Além disso, estudos do nosso grupo de pesquisa demonstram que a restrição proteica materna impacta o desenvolvimento e aumenta a incidência de lesões prostáticas na prole de ratos velhos. Apesar disto, os mecanismos moleculares que desencadeiam estas alterações ainda são pouco conhecidos. Neste contexto, o avanço das metodologias de estudo de expressão gênica e proteica em larga-escala, associado à possibilidade de integração destes dados utilizando ferramentas de bioinformática, tem possibilitado uma visão integrativa global dos mecanismos moleculares em condições normais e patológicas. Assim, o objetivo deste trabalho foi identificar o perfil de expressão global de RNAs mensageiros (transcriptoma) e de proteinas (proteômica) em amostras de próstatas de ratos que sofreram restrição proteica perinatal e integrar o perfil global de expressão de mRNAs e proteínas para identificar redes de regulação e vias moleculares envolvidas no desenvolvimento prostático em animais normais e restritos. Foram analisados ratos machos da linhagem Sprague Dawley com 21 dias de idade pós-natal nascidos de mães alimentadas com ração padrão (17% de proteína) ou de mães alimentadas com ração hipoproteica (6% proteína) durante a gestação e lactação. Após este período, os animais foram eutanasiados com overdose de anestésico, pesados e a próstata ventral foi coletada. Foram analisados o transcriptoma por sequenciamento de última geração (HigSeq-2500, Illumina) e do proteoma, por espectrometria de massas (LC-Ms/Ms). Foram selecionados alguns alvos de interesse para serem validados por RT-qPCR, assim como por imunohistoquímica e western blotting. Estes resultados foram comparados aos dados de transcriptoma e do proteoma para adenocarcinoma prostático, disponíveis na literatura, como o objetivo de investigar se a restrição proteica perinatal é responsável por alterar a expressão gênica e proteica de alvos relacionados ao desenvolvimento de lesões prostáticas. Outros animais forma eutanasiados com 540 dias de idade com o objetivo de se identificar possíveis alvos alterados tanto pela restrição proteica em ratos jovens como no câncer prostático. Este projeto de doutorado faz parte de um projeto maior (auxílio regular à pesquisa), onde também foi analisado o microRNoma e o perfil de metilação global na próstata de ratos submetidos à restrição proteica perinatal. Com isso espera-se obter uma visão global dos efeitos da restrição proteica perinatal sobre a biologia prostática. Maternal exposure to a protein-deficient diet during pregnancy is associated with the development of diseases in the offspring, especially cardiovascular, renal, metabolic and even cancer. In addition, studies by our research group demonstrate that maternal low protein diet (LPD) impacts development and increases the incidence of prostatic lesions in the offspring of old rats. The molecular mechanisms that trigger these changes are still poorly understood. Thus, in this study was to identify the global expression profile of messenger RNAs (transcriptome) and proteins (proteome) in ventral prostate (VP) samples from young rats submitted to maternal LPD during gestation and lactation, and to integrate molecular pathways involved in prostate development in normal and restricted animals. We used male Sprague Dawley rats on the postnatal day (PND) 21 born to dams fed standard diet (17% protein) (control group -CTR), or damsfed LPD (6% protein) during gestation and lactation (gestation and lactation LPD group -GLLP). After this period, the animals were euthanized with anesthetic overdose, weighed and the VP collected. We observed a delay in the stages of prostate development (lower body weight and PV weight) at birth on PND 1), accompanied by disbalance hormonal (increased levels of cholesterol, testosterone and estrogen on PND 21). Proteome analyzes (LC-MS/MS) revealed changes in the pretein profile of the prostate gland in these animals, showing enrichment of molecular pathways associated with the estrogenic disturbance and cancer profile. Transcriptome analysis (HigSeq-2500, Ilumina) revealed a distinct gene profile between the CTR and GLLP groups, showing genes alteraed by maternal LPD were involved in development, cytochrome p450 and cancer pathways. All results were compared to the transcriptome and proteome data for prostate adenocarcionoma (PRAD) in The Cancer Genome Atlas (TCGA) database, with the aim of investigating whether maternal LPD is responsible for altering the gene and protein expression of targets related to the development of lesions prostatic, data associated with the profile of animals in DPN 50 submitted to maternal LPD. Our results highlight that the role of RPM in the normal development of the prostate, altering the molecular pathways that promote the carcinogenesis of the slow-growing prostate with aging. In addition, in silico analysis can be a useful tool to characterize potential biomarkers and molecular pathways involved in rodent and human prostate carcinogenesis. FAPESP: 17/08715-0 CAPES 001

- Abstract
HbSC disease, a less severe form of sickle cell disease, affects the retina more frequently and patients have higher rates of proliferative retinopathy that can progress to vision loss. This study aimed to identify differences in the expression of endothelial cell-derived molecules associated with the pathophysiology of proliferative sickle cell retinopathy (PSCR). RNAseq was used to compare the gene expression profile of circulating endothelial colony-forming cells from patients with SC hemoglobinopathy and proliferative retinopathy (n = 5), versus SC patients without retinopathy (n = 3). Real-time polymerase chain reaction (qRT-PCR) was used to validate the RNAseq results. A total of 134 differentially expressed genes (DEGs) were found. DEGs were mainly associated with vasodilatation, type I interferon signaling, innate immunity and angiogenesis. Among the DEGs identified, we highlight the most up-regulated genes ROBO1 (log2FoldChange = 4.32, FDR = 1.35E-11) and SLC38A5 (log2FoldChange = 3.36 FDR = 1.59E-07). ROBO1 , an axon-guided receptor, promotes endothelial cell migration and contributes to the development of retinal angiogenesis and pathological ocular neovascularization. Endothelial SLC38A5, an amino acid (AA) transporter, regulates developmental and pathological retinal angiogenesis by controlling the uptake of AA nutrient, which may serve as metabolic fuel for the proliferation of endothelial cells (ECs) and consequent promotion of angiogenesis. Our data provide an important step towards elucidating the molecular pathophysiology of PSCR that may explain the differences in ocular manifestations between individuals with hemoglobinopathies and afford insights for new alternative strategies to inhibit pathological angiogenesis., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 da Silva Costa, Ito, da Cruz, De Souza, Rios, Bertozzo, Camargo, Viturino, Lanaro, de Albuquerque, do Canto, Saad, Ospina-Prieto, Ozelo, Costa and de Melo.)

- Abstract
Aim: To evaluate the sex-specific effects of a hydroalcoholic extract from Eugenia punicifolia (HEEP) leaves on gastric ulcer healing., Methods: In this rat study involving males, intact (cycling) females, and ovariectomized females, gastric ulcers were induced using acetic acid. A vehicle, lansoprazole, or HEEP was administered for 14 d after ulcer induction. Body weight was monitored throughout the treatment period. At the end of treatment, the rats were euthanized and the following in vivo and in vitro investigations were performed: macroscopic examination of the lesion area and organ weights, biochemical analysis, zymography, and evaluation of protein expression levels. Additionally, the concentration-dependent effect of HEEP was evaluated in terms of subacute toxicity and cytotoxicity., Results: Compared to the vehicle, HEEP demonstrated a great healing capacity by substantially reducing the ulcerative lesion area in males (52.44%), intact females (85.22%), and ovariectomized females (65.47%), confirming that HEEP accelerates the healing of acetic acid-induced gastric lesions and suggesting that this effect is modulated by female sex hormones. The antiulcer effect of HEEP was mediated by prostaglandin E
2 only in male rats. Overall, the beneficial effect of HEEP was the highest in intact females. Notably, HEEP promoted the expression of vascular endothelial growth factor (intact vs ovariectomized females) and decreased the expression of Caspase-8 and Bcl-2 (intact female vs male or ovariectomized female). Additionally, HEEP enhanced fibroblast proliferation and migration into a wounded area in vitro , confirming its healing effect. Finally, no sign of subacute toxicity or cytotoxicity of HEEP was observed., Conclusion: In gastric ulcers, HEEP-induced healing (modulated by female sex hormones; in males, mediated by prostaglandin) involves extracellular matrix remodeling, with gastric mucosa cell proliferation and migration., Competing Interests: Conflict-of-interest statement: The authors declare that they have no commercial, personal, political, intellectual, or religious interests related to the work presented herein.- Published
