Early-onset acute myocardial infarction (AMI) may have a higher genetic predisposition than late-onset AMI does. The present study aimed to identify and characterize germline variants that affect early-onset AMI using whole-genome sequencing (WGS). We performed a genome-wide association study based on WGS of 1,239 Koreans, including 596 early-onset AMI patients and 643 healthy individuals. Patients with AMI who underwent percutaneous coronary intervention (PCI) caused by atherothrombotic occlusive lesions were included in the study. A total of 29 novel loci were found to be associated with early-onset AMI. These loci are involved in thrombosis, fibrinolysis, inflammation, and lipid metabolism. One of the associated single nucleotide variants (SNVs), rs1614576, located upstream of PRKCB, is known to be associated with thrombus formation. Additionally, the results revealed a novel locus, rs78631167, located upstream of PLAUR which plays a critical role in regulating plasminogen activation and is related to fibrinolysis. The association between early-onset AMI and rs9357455, which is located upstream of PHACTR1 that regulates inflammation in AMI, was found. Moreover, we could identify a lipid metabolism related genetic risk locus, rs5072, in the APOA1-AS gene. This study provides new evidence supporting the genetic association between early-onset AMI and thrombosis and fibrinolysis, as well as inflammation and lipid metabolism, by analyzing the whole-genome of 596 patients with early-onset AMI who have been treated with PCI. Our findings highlight potential genetic markers for the prediction and management of AMI, as well as for understanding the etiology of AMI.

Anti-oviposition induced by Cordyceps fumosorosea FG340 to Spodoptera exigua and its persistence had been assessed on the Chinese cabbage seedlings sprayed with 0, 106, 107 and 108 conidia per mL in greenhouse and laboratory. In a randomized complete block, four couples (males and females) of moths were released in each cage. In the laboratory, the percentage of egg laid varied significantly between treatments with 59.8, 14.8, 11.9, and 13.5% on 0, 106, 107 and 108 conidia per mL; respectively. Similarly, in the greenhouse, the percentage of eggs laid differed significantly between suspensions with 88.18, 8.7, 0, and 3.13% on 0, 106, 107, and 108 conidia per mL; respectively. Repellence study showed that there is a major difference between suspensions with average 34.55, 35.21 and 40.02% for 106, 107 and 108 conidia per mL; respectively. Endophytic C. fumosorosea and its culture fluid affect the behavior of armyworm larvae. The concentration of 108 conidia per mL can affect the oviposition of the armyworm.

Background Amaranth (Amaranthus spp. L) is not native in South Korea but cultivated in small scales for ornamental purpose as well as a leafy vegetables and pseudo cereals. In this study, a new species within the genus Fusarium was isolated from amaranth showing stem rot symptom from a farmer field in Hwaseong, South Korea. The diseased characterized by dark-brown spot with black border and then get withered.Methods and results Phylogenetic analysis based concatenated sequences of translation elongation factor 1-alpha and DNA-dependent RNA polymerase II second largest subunit genes, revealed that the obtained isolate was clearly distinct other species of Fusarium fujikuroi species complex and the closely related to F. circinatum. Cultural and morphological characteristics and pathogenicity on healthy amaranth plant (stem and leaves) were examined. The isolate was readily differentiating from F. circinatum based on 1–5 septate macro conidia and absence of sterile hyphae.Conclusions Based on molecular and morphological characteristics, this fungus demonstrated to be a new species and described here as Fusarium amaranthuense, the causal agent of stem rot of amaranth in South Korea.

One of the causes of sarcopenia is that homeostasis between anabolism and catabolism breaks down due to muscle metabolism changes. Rutin has shown antioxidant and anti-inflammatory effects in various diseases, but there are few studies on the effect on muscle loss with aging. The effect of rutin on muscle loss was evaluated using dexamethasone-induced muscle loss C2C12 myoblast and mouse model. In the group treated with dexamethasone, the muscle weight of gastrocnemius (GA), tibialis anterior (TA), and extensor digitorum longus (EDL) in the mouse model were significantly decreased (p < 0.0001 in GA, p < 0.0001 in TA, and p < 0.001 in EDL) but recovered (p < 0.01 in GA, p < 0.0001 in TA, and p < 0.01 in EDL) when treated with rutin. MAFbx, MuRF1, and FOXO3 protein expression of C2C12 myoblast were significantly increased (p < 0.01 in MAFbx, p < 0.01 in MuRF1, and p < 0.01 in FOXO3) when treated with dexamethasone, but it was recovered (p < 0.01 in MAFbx, p < 0.01 in MuRF1, and p < 0.01 in FOXO3) when rutin was treated. In addition, MAFbx and FOXO3 protein expression in GA of mouse model was significantly increased (p < 0.0001 in MAFbx and p < 0.001 in FOXO3) when treated with dexamethasone, but it was also recovered (p < 0.01 in MAFbx and p < 0.001 in FOXO3) when rutin was treated. The present study shows that rutin blocks the FOXO3/MAFbx and FOXO3/MuRf1 pathways to prevent protein catabolism. Therefore, rutin could be a potential agent for muscle loss such as sarcopenia through the blocking ubiquitin-proteasome pathway associated with catabolic protein degradation.

Introduction: Worldwide, 158 million people over the age of 50 are estimated to have high risk of osteoporotic fractures. It is important to prevent the occurrence of primary fractures by diagnosing and treating osteoporosis at an early stage. Dual energy absorptiometry (DEXA) is one of the preferred modality for screening or diagnosis of osteoporosis and can predict the risk of hip fracture to some extent. However, the DEXA test may be difficult to implement easily in some developing countries and fractures have been observed before patients underwent DEXA. The purpose of this systematic review is to search for studies that predict the risk of hip fracture using AI or ML, organize the results of each study, and analyze the usefulness of this technology. Methods: PubMed Central, OVID Medline, Cochrane Collaboration Library, Web of Science, EMBASE, and AHRQ databases were searched to identify relevant studies published up to June 2022 with English language restriction. The following search terms were used ("hip fractures"[MeSH Terms] OR ("hip"[All Fields] AND "fractures"[All Fields]) OR "hip fractures"[All Fields] OR ("hip"[All Fields] AND "fracture"[All Fields]) OR "hip fracture"[All Fields]) AND ("artificial intelligence"[MeSH Terms] OR ("artificial"[All Fields] AND "intelligence"[All Fields]) OR "artificial intelligence"[All Fields]). Results: 7 studies are included in this study. The total number of subjects included in the 7 studies was 330,099. There were 3 studies that included only women, and 4 studies included both men and women. One study conducted AI training after 1:1 matching between fractured and non-fractured patients. The AUC of AI prediction model for hip fracture risk was 0.39–0.96. The accuracy of AI prediction model for hip fracture risk was 70.26–90%. Conclusion: We believe that predicting the risk of hip fracture by the AI model will help select patients with high fracture risk among osteoporosis patients. However, in order to apply the AI model to the prediction of hip fracture risk in clinical situations, it is necessary to identify the characteristics of the dataset and AI model and use it after performing appropriate validation.

Background In the emergency room, clinicians spend a lot of time and are exposed to mental stress. In addition, fracture classification is important for determining the surgical method and restoring the patient's mobility. Recently, with the help of computers using artificial intelligence (AI) or machine learning (ML), diagnosis and classification of hip fractures can be performed easily and quickly. The purpose of this systematic review is to search for studies that diagnose and classify for hip fracture using AI or ML, organize the results of each study, analyze the usefulness of this technology and its future use value. Methods PubMed Central, OVID Medline, Cochrane Collaboration Library, Web of Science, EMBASE, and AHRQ databases were searched to identify relevant studies published up to June 2022 with English language restriction. The following search terms were used [All Fields] AND (", "[MeSH Terms] OR (""[All Fields] AND "bone"[All Fields]) OR "bone fractures"[All Fields] OR "fracture"[All Fields]). The following information was extracted from the included articles: authors, publication year, study period, type of image, type of fracture, number of patient or used images, fracture classification, reference diagnosis of fracture diagnosis and classification, and augments of each studies. In addition, AI name, CNN architecture type, ROI or important region labeling, data input proportion in training/validation/test, and diagnosis accuracy/AUC, classification accuracy/AUC of each studies were also extracted. Results In 14 finally included studies, the accuracy of diagnosis for hip fracture by AI was 79.3–98%, and the accuracy of fracture diagnosis in AI aided humans was 90.5–97.1. The accuracy of human fracture diagnosis was 77.5–93.5. AUC of fracture diagnosis by AI was 0.905–0.99. The accuracy of fracture classification by AI was 86–98.5 and AUC was 0.873–1.0. The forest plot represented that the mean AI diagnosis accuracy was 0.92, the mean AI diagnosis AUC was 0.969, the mean AI classification accuracy was 0.914, and the mean AI classification AUC was 0.933. Among the included studies, the architecture based on the GoogLeNet architectural model or the DenseNet architectural model was the most common with three each. Among the data input proportions, the study with the lowest training rate was 57%, and the study with the highest training rate was 95%. In 14 studies, 5 studies used Grad-CAM for highlight important regions. Conclusion We expected that our study may be helpful in making judgments about the use of AI in the diagnosis and classification of hip fractures. It is clear that AI is a tool that can help medical staff reduce the time and effort required for hip fracture diagnosis with high accuracy. Further studies are needed to determine what effect this causes in actual clinical situations.

Background: Recently, open pose estimation using artificial intelligence (AI) has enabled the analysis of time series of human movements through digital video inputs. Analyzing a person's actual movement as a digitized image would give objectivity in evaluating a person's physical function. In the present study, we investigated the relationship of AI camera-based open pose estimation with Harris Hip Score (HHS) developed for patient-reported outcome (PRO) of hip joint function. Method: HHS evaluation and pose estimation using AI camera were performed for a total of 56 patients after total hip arthroplasty in Gyeongsang National University Hospital. Joint angles and gait parameters were analyzed by extracting joint points from time-series data of the patient's movements. A total of 65 parameters were from raw data of the lower extremity. Principal component analysis (PCA) was used to find main parameters. K-means cluster, X-squared test, Random forest, and mean decrease Gini (MDG) graph were also applied. Results: The train model showed 75% prediction accuracy and the test model showed 81.8% reality prediction accuracy in Random forest. “Anklerang_max”, “kneeankle_diff”, and “anklerang_rl” showed the top 3 Gini importance score in the Mean Decrease Gini (MDG) graph. Conclusion: The present study shows that pose estimation data using AI camera is related to HHS by presenting associated gait parameters. In addition, our results suggest that ankle angle associated parameters could be key factors of gait analysis in patients who undergo total hip arthroplasty.

Accelerated global warming is leading to the loss of plant species diversity, and

This study aimed to investigate the effect of light [a long-day photoperiod (16 h light/8 h dark cycle)] and dark treatment on the production of rosmarinic acid in P. frutescens microgreens and to determine its antioxidant and antibacterial activities. Microgreens of P. frutescens were grown under light and dark conditions and harvested after 10, 15, 20, and 25 days of each treatment. Although dry weight values of microgreens gradually increased from 10 to 25 days of both treatments, the microgreens grown under light treatment possessed slightly higher levels of dry weight than those grown in the dark. Rosmarinic acid and total phenolic content (TPC) were also analyzed using high-performance liquid chromatography (HPLC) and Folin–Ciocalteu assay. The accumulation patterns of rosmarinic acid and TPC gradually increased and decreased, respectively, in P. frutescens microgreens grown in continuous darkness. The highest accumulation was observed in microgreens grown for 20 days. However, rosmarinic acid and TPC values were not significantly different in microgreens grown under light conditions. According to the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical inhibition assay, the extracts of P. frutescens microgreens were confirmed to be strong antioxidants, and their ability to scavenge DPPH radicals was positively correlated with the total phenolic content in the microgreens after 10, 15, 20, and 25 days of both treatments. Considering the relatively higher values of dry weight, rosmarinic acid, TPC, and DPPH assay, P. frutescens microgreens after 20 days of darkness and 20 days of light treatment, respectively, were selected for screening antibacterial activity using nine pathogens. Both microgreen extracts showed strong antibacterial activity against pathogens. In particular, the extracts of microgreens grown for 20 days under light treatment showed higher antimicrobial effects. Therefore, the light treatments for 20 days, as well as the darkness treatment for 20 days, were the best conditions for P. frutescens microgreen production because of their high levels of dry weight, phenolics, and biological activities.

Gom-chwi (Ligularia fischeri) is severely infected with Phytophthora drechsleri, the causal organism of Phytophthora root rot, an economically important crop disease that needs management throughout the cultivation period. In the present study, Phytophthora root rot was controlled by using bacterial isolates from rhizosphere soils collected from various plants and screened for antagonistic activity against P. drechsleri. A total of 172 bacterial strains were isolated, of which, 49 strains showed antagonistic activities by dual culture assay. In the seedling assay, six out of the 49 strains showed a predominant effect on suppressing P. drechsleri. Among the six strains, the ObRS-5 strain showed remarkable against P. drechsleri when treated with seed dipping or soil drenching. The ObRS-5 strain was identified as Enterobacter asburiae based on 16S ribosomal RNA gene sequences analysis. The bacterial cells of E. asburiae ObRS-5 significantly suppressed sporangium formation and zoospore germination in P. drechsleri by 87.4% and 66.7%, respectively. In addition, culture filtrate of E. asburiae ObRS-5 also significantly inhibited sporangium formation and zoospore germination by 97.0% and 67.6%, respectively. Soil drenched bacterial cells, filtrate, and culture solution of E. asburiae ObRS-5 effectively suppressed Phytophthora root rot by 63.2%, 57.9%, and 81.1%, respectively. Thus, E. asburiae ObRS-5 could be used as a potential agent for the biological control of Phytophthora root rot infecting gom-chwi.

Hyperuricemia plays an essential role in the development of gout. Despite the clinical importance of hyperuricemia, a direct relationship between oral health and hyperuricemia has not been established. Therefore, we aim to investigate the association between oral health and hyperuricemia in Korean adults.We selected 17,584 subjects from the Korea National Health and Nutrition Examination Survey 2016–2019 database. Oral health-related variables included the number of dental caries, regular tooth brushing, use of secondary oral products, and regular dental examination. The odds ratio (OR) and 95% confidence intervals (CIs) for hyperuricemia were calculated using a multivariable-adjusted logistic regression model.In all subjects, oral health status with dental caries and oral health behaviors, including tooth brushing; secondary oral products; and regular dental examination, were significantly associated with hyperuricemia. The adjusted OR and 95% CIs for hyperuricemia comparing more than three dental caries with no dental caries were 1.28 (1.08–1.51). The adjusted OR and 95% CIs for hyperuricemia in regular tooth brushing, use of secondary oral products, and regular dental examination were 0.78 (0.67–0.91), 0.91 (0.82–1.00), and 0.86 (0.78–0.95), respectively. Notably, the association between oral health and hyperuricemia was more prominent in male subjects. In addition, when subjects were grouped by the scoring system regarding oral health, the prevalence of hyperuricemia was lower in groups with a better oral health score.In conclusion, we demonstrated that oral health status and behaviors were associated with hyperuricemia, especially in males. Further complementary studies are needed to confirm the definite association between oral health and hyperuricemia.

The formation and pollution of particulate matter (PM), a side effect of rapid industrialization and urbanization, is considered a global issue. However, various plant species are able to effectively capture and reduce atmospheric PM concentrations. We investigated the indoor growth and morphology of 21 indigenous Korean evergreen species at low light intensities to ascertain their ability to reduce PM of aerosol particles in a closed acrylic chamber. The decrease in PM mass concentration differed significantly across species, with a significant correlation (8 h, p &lt, 0.001). The reduction in the mass concentration of PM differed with particle size and across species. The highest reduction of PM2.5 occurred after 8 h with Dryopteris lacera (86.8%), Ilex × wandoensis (84.9%), Machilus thunbergii (84.3%), and Rhododendron brachycarpum (84.0%). Reduction of PM10 after 8 h was highest with Cephalotaxus harringtonii (98.3%), I. × wandoensis (98.5%), M. thunbergii (98.5%), and R. brachycarpum (98.3%). Plant morphological characteristics (category, plant height, leaf shape, leaf area) and relative humidity were closely related to the decrease in PM mass concentration. In conclusion, our findings can be used to identify Korean plant species that can reduce PM concentration and are suitable for indoor use.

This study endeavored to sustainably control aphids and anthracnose after spraying endophytic Isaria javanica pf185 under field conditions. Under two different tents, one batch of seedlings was sprayed with a 107 conidia/mL I. javanica pf185 suspension, while another was sprayed with 0.05% Tween 80® in distilled water. Six leaf discs from the top, middle, and bottom part of the plant canopy were weekly collected and placed on moistened filter paper in a Petri dish for insecticidal and antifungal bioassays against Myzus persicae and Colletotrichum acutatum. Differences were noticed from the 18th day after spraying with mortality (86.67 ± 0.57% versus 36.67 ± 0.64%) and leaf damage (13.45 ± 0.03% versus 41.18 ± 0.06%) on fungus-treated and controlled, respectively. The corrected insecticidal efficacy was 20.43, 39.82, 72.32, 66.43 and 70.04%, while the corrected fungicidal efficacy was 26.07, 38.01, 53.35, 29.08 and 41.81% during five successive weeks. A positive correlation was evident between insecticidal efficacy and relative humidity (r2 = 0.620) and temperature (r2 = 0.424), respectively. No correlation was found between antifungal activity and relative humidity (r2 = 0.061) and temperature (r2 = 0), respectively. The entomopathogenic fungus survived on leaf surface area and in tissues after spraying.

Cilostazol exerts potent anti-inflammatory effects and celecoxib, a COX-2 specific inhibitor, improves the unsatisfactory profile of NSAIDs. It was aimed to assess the anti-arthritic potential of celecoxib add-on for cilostazol therapy in collagen induced arthritis (CIA), and to elucidate the implication of interleukin (IL)-10 in the action of cilostazol and celecoxib cotreatment. Cotreatment of RAW 264.7 cells with 10 μM cilostazol and 0.3 μM celecoxib synergistically suppressed RANKL-induced increases in RANK mRNA and protein levels. When cultured in the presence of RANKL for 5 days, RANKL-stimulated expressions of osteoclastogenic genes (OSCAR, DC-STAMP, and cathepsin K mRNA) and the expression of RANK mRNA were markedly elevated. Furthermore, these gene expressions, including that of RANK, were significantly suppressed by cotreatment with cilostazol (10 μM) and celecoxib (0.3 μM). In addition, this co-treatment strongly down-regulated RANKL-induced NFATc1 protein and TRAP activity (key osteoclastogenic factors), and these down-regulations were significantly prevented by pretreating cells with IL-10 neutralizing antibody. Furthermore, increased osteoclast formation and extensive resorption pit formation by bone marrow-derived monocytes obtained from C57BL/6 mice cultured in the presence of M-CSF/RANKL were markedly suppressed by cilostazol and celecoxib cotreatment. Consequently, hindlimb paw thicknesses in DBA/1J CIA mice were significantly reduced by cilostazol (10 mg/kg/d) and celecoxib (5 mg/kg/d) cotreatment. These results were accompanied by synergistic suppression of cartilage depletion and bone erosion and reductions in arthritis scores in the CIA mice. In conclusion, serum IL-10 levels in these mice were markedly increased by cilostazol and celecoxib cotreatment, whereas elevated serum IL-1β levels were markedly reduced. Cotreatment with low-dose cilostazol and celecoxib may ensure the synergistic anti-arthritic potential.

Cilostazol (an inhibitor of phosphodiesterase type III) has potent anti-inflammatory effects, and celecoxib (a COX-2 specific inhibitor) has been reported to improve the unsatisfactory profile of NSAIDs. This study investigated the synergistic anti-arthritic potential of a multitarget-based cotreatment, in which cilostazol was used as an add-on therapy for celecoxib, using the synovial fibroblasts of RA patients (RASFs). Increased COX-2 protein expression and PGE2 synthesis by LPS (1 μg/ml) were significantly and synergistically attenuated by cotreatment with 3 μM cilostazol and 30 μM celecoxib, whereas monotherapy with either cilostazol or celecoxib showed little effects. IL-10 mRNA levels in LPS-treated RASFs were moderately increased by pretreating cilostazol (1–10 μM) or celecoxib (10–50 μM) monotherapy, but 3 μM of cilostazol add-on for 30 μM celecoxib treatment synergistically increased IL-10 mRNA levels and IL-10 release to culture media. Cilostazol and celecoxib cotreatment similarly showed synergistic increase in SOCS3 mRNA levels. Accordingly, LPS-induced increases in IL-1β and IL-6 mRNA and TNF-α release were significantly and synergistically diminished by cilostazol and celecoxib cotreatment. Moreover, synovial cell proliferation was significantly suppressed by cotreatment. Summarizing, cotreatment with cilostazol and celecoxib exhibited a synergistic increase in IL-10 production and SOCS3 expressions, thereby resulted in synergistic decreases in IL-1β mRNA, IL-6 mRNA expression and TNF-α synthesis in association with synergistic decreases in COX-2 and PGE2 protein expression in the RA synovial fibroblasts. In conclusion, these observations suggest low concentrations of cilostazol and celecoxib cotreatment may ensure a synergistic anti-arthritic potential.

In South Korea, comprehensive taxation, which is a combination of income from various sources, has been applied to financial income exceeding a certain amount. However, criticism continues to be raised that the level of financial income is lower compared with other incomes, and South Korea’s taxation authorities lowered the standard amount in 2013, thereby increasing the tax burden on financial income. This study aims to analyze the response of the bond market to the reduction of the standard amount of comprehensive taxation for financial income. This study analyzes the implicit tax phenomenon that the pre-tax return of bonds with large tax benefits is relatively low, in Korean bond market. It suggests that the sustainability level of the bond market has increased as the difference between the yield of the National Housing Bond, which has a large tax burden after 2013, and that of the general Korean Treasury Bond has decreased to a statistically significant level. Therefore, this study proposes that tax reforms on financial income may affect not only the level of tax burden but also the macro-economy of money transfers among financial instruments and financial markets.

Numerous small-molecule inhibitors (SMIs) have been approved as adjuvant or first-line therapies for malignancies. Based on cancer treatment using SMIs, next-generation SMIs that can be used to optimize the therapeutic index, overcome drug resistance, and establish combination therapies are in development. Osteoarthritis (OA) is the most common chronic joint disease with senescence, and there are various approaches to OA treatment; however, the gold standard treatment is controversial. Therefore, in this manuscript, we demonstrated the potential of using SMIs in OA treatment and described the general strategies for using SMIs in OA treatment.

The abnormal self-assembly of amyloid-beta (Aβ) peptides into oligomers, as well as insoluble fibrils, has been identified as a key factor for monitoring the progression of Alzheimer’s disease (AD). The noninvasive imaging of Aβ aggregates utilizing chemical probes can be a powerful and practical technique for accurately diagnosing and monitoring the progress of AD, as well as evaluating the effectiveness of therapeutic drug candidates in treating or managing it. Particularly, the near-infrared (NIR) fluorescence imaging of Aβ plaques is a potentially promising approach toward the efficient detection of the biomarker. In this study, we describe a new NIR fluorophore, which was based on curcumin derivatives. The fluorophore is equipped with desirable optical properties for in vivo brain imaging. The emission wavelength of the probe, 8b, is 667 nm, and its fluorescent intensity is significantly increased through binding with the Aβ aggregates. The probe allows the clear visualization of the Aβ plaques 10 min post administration, and the intensity of the fluorescent signal in the brain of a 5XFAD transgenic mouse model is more than three times higher than that of the normal control group. These results demonstrate that the designed probe can be an effective tool for visualizing Aβ plaques, as well as investigating the pathological progress of AD.

Increasing urbanization has highlighted the need for more green spaces in built-up areas, with considerable attention of vertical installations such as green walls and rooftop gardens. This study hypothesizes that the rooftop-garden-induced temperature reduction effects vary depending on the type of arrangements. Therefore, the objective of this study is to find the most efficient arrangement of the roof gardens for temperature reduction. This paper presents the results of a quantitative analysis of the temperature reduction effect of rooftop gardens installed on structures and sites on the campus of Seoul National University. An ENVI-Met simulation is utilized to analyze the effects of roads, buildings, green areas, and vacant land on temperature and humidity. The effects of the following five rooftop garden configurations were compared: extreme, linear (longitudinal), linear (transverse), checkerboard, and unrealized rooftop gardens. The extreme and linear (longitudinal) gardens achieved the maximum temperature reduction, &minus, 0.3 &deg, C, while the lowest maximum reduction of &minus, 0.2 &deg, C was achieved by the checkerboard pattern. Over larger areas, the greatest impact has been recorded in the mornings rather than in the afternoons. The results of this study will be useful for those planning and installing rooftop gardens at the district and city levels.

Nonalcoholic fatty liver disease (NAFLD) is an increasingly studied condition that can progress to end-stage liver disease. Although NAFLD was first described in 1980, a complete understanding of the mechanism and causes of this disease is still lacking. Six-transmembrane protein of prostate 2 (STAMP2) plays a role in integrating inflammatory and nutritional signals with metabolism. Our previous study suggested that STAMP2 may be a suitable target for treating NAFLD. In the current study, we performed a focused drug-screening and found that cilostazol could be a potential STAMP2 enhancer. Thus, we examined whether cilostazol alleviates NAFLD through STAMP2. The in vivo and in vitro pharmacological efficacies of cilostazol on STAMP2 expression and lipid accumulation were analyzed in NAFLD mice induced by high-fat diet (HFD) and in HepG2 cell lines treated by oleic acid (OA), respectively. Cilostazol increased the expression of STAMP2 through transcriptional regulation in vivo and in vitro. Cilostazol also dampened the STAMP2 downregulation caused by the HFD and by OA in vivo and in vitro, respectively. Cilostazol activated AMP-activated protein kinase (AMPK) in vivo and in vitro, and AMPK functions upstream of STAMP2, and reversed downregulation of STAMP2 expression through AMPK in the NAFLD model. Cilostazol ameliorates hepatic steatosis by enhancing hepatic STAMP2 expression through AMPK. Enhancing STAMP2 expression with cilostazol represents a potential therapeutic avenue for treatment of NAFLD.
