Oxidative stress has impacts on the KRas and Nrf2/Keap1 pathways, which have multiple interactions with each other and play important roles in colorectal cancer (CRC). This study investigated the expressions of proteins in the KRas and Nrf2/Keap1 pathways and their associations with clinicopathological features in CRC. The protein levels of Nrf2, Keap1, Bach1, p62, HO1, KRas, Erk, Raf1 and PI3K in both the tumour and normal tissues of 60 CRC subjects were determined by Western blot and their T/N (tumour/normal tissue) ratios were correlated with clinicopathological features. The T/N ratios of proteins in the KRas and Nrf2/Keap1 pathways had correlation patterns and proximity profiles in cluster dendrograms different in CRC with different status of lymphovascular invasion (LVI) or lymph node/distant metastases. The Keap1 protein T/N ratio was a significant predictor (odd ratio: 2.24; 95% confidence interval: 1.26 − 4.38) of LVI, which in turn predicted metastases (11.0; 3.49 − 39.8). The interactions between the KRas and Nrf2/Keap1 pathways may be affected differently by LVI and metastases, and the protein T/N ratio of Keap1 may be helpful for predicting LVI in CRC.

Systemic inflammation plays a pivotal role in colorectal cancer (CRC) development. Two hallmarks reflect the severity of inflammation—circulating cytokines and nutrition-inflammation biomarkers (NIBs); however, their interplay has not been fully investigated. In total, 128 CRC patients were included. Ten circulating cytokines (TNF-α, TGF-β, IFN-γ, IL-1β, IL-4, IL-6, IL-10, IL-12, IL-13, and IL-23) and NIBs were analyzed. The relationship between cytokines, NIBs, clinicopathological variables, and overall survival (OS) was assessed using univariate and multivariate analyses. Three NIBs (CRP-to-albumin ratio [CAR]), neutrophil-to-lymphocyte ratio [NLR]), and prognostic nutritional index [PNI]) were associated with OS in univariate analysis; however, CAR was better for OS prediction in multivariate analysis (P = 0.015). None of the serum cytokines analyzed showed a significant association with OS. High CAR (≥0.25) and high IL-10 (≥76.6 pg/mL), high NLR (≥8.2) and high IL-23 (≥51.2 pg/mL), and high PNI (≥42.4) and high IL-1β (≥14.3 pg/mL) values were correlated. CAR, NLR, and PNI were not correlated with each other, whereas circulating cytokines were closely interrelated. High CAR was an independent predictor of poor OS in patients with CRC. Different NIBs have unique cytokine profiles, but show no correlation with each other. There is a close association among the circulating cytokines. [ABSTRACT FROM AUTHOR]

The Nrf2 (nuclear factor erythroid 2-like 2; NFE2L2)/Keap1 (Kelch-like ECH-associated protein 1) pathway and the TXN (thioredoxin)/GSH (glutathione) system interact mutually and regulate cellular redox with impacts on cancer metastasis and S-glutathionylation of protein, which is an indicator of cell distress. This study investigates the levels of proteins in the Nrf2/Keap1 pathway and the TXN/GSH system and SGP (S-glutathionylated protein) in CRC (colorectal cancer) with or without metastasis. The protein levels of Nrf2, Keap1, Bach1 (BTB domain and CNC homolog 1), TXN, TXNRD1 (thioredoxin reductase 1), GSR (glutathione reductase) and SGP with molecular weight 31–172 kDa in the normal and tumour tissues of 64 CRC subjects were determined by Western blot. The protein levels and their T/N (tumour/normal tissue) ratios of the Nrf2/Keap1 pathway, the TXN/GSH system and SGP were correlated to different extents in the tissues of CRC subjects with or without lymph node/distant metastasis. The T/N ratios of SGP (odd ratio: 0.19; 95% CI: 0.04–0.74) and lympho-vascular invasion (4.2; 1.39–13.73) were significant predictors for metastasis. SGPs have protein levels correlated with those of the Nrf2/Keap1 pathway and their T/N ratios are a negative predictor for metastasis in CRC. [ABSTRACT FROM AUTHOR]

- Abstract
Cancer stem cells play critical roles in tumor initiation, progression, and relapse. Since we previously found that GATA6 promotes the stemness in HCT‐116 and HT‐29 human colorectal cancer (CRC) cells, we aimed to identify the downstream mediator(s) of the stemness‐stimulating effect of GATA6 herein. LRH‐1 was found as a direct target of GATA6 and its upregulation promoted the stemness in both HCT‐116 and HT‐29 cells. Subsequently, hypoxia‐inducible factor‐1α (HIF‐1α) was identified as a direct target of LRH‐1 and its expression level and activity were significantly elevated in the LRH‐1‐overexpressing clones established from the aforementioned two CRC lines. Accordingly, the expression levels of several HIF‐1α targets were also markedly increased, resulting in a stronger glycolysis associated with dramatic elevations of the lactate levels in these cells. Strikingly, higher mitochondrial activities were also found in these clones which might be attributed to the increase of PGC‐1α stimulated by the lactate uptaken through the upregulated MCT‐1. Finally, significant increases in the self‐renewal ability, intracellular radical oxygen species levels and mitochondrial mass were detected in the CD133+/CD44+ subpopulations isolated from CRC cells regardless of their LRH‐1 expression levels. Together, our results suggest a novel metabolic symbiosis between different colorectal cancer stem cell subpopulations critical for maintaining their mutual stemness. [ABSTRACT FROM AUTHOR]

The interaction between hyaluronan and CD44, an important cancer stem‐cell marker, stimulates various tumor cell‐specific functions such as the stemness of tumor cells. microRNA‐203 (miR‐203) can be downregulated by this interaction in human colorectal cancer (CRC) cells, which increases their stemness; however, the underlying mechanism is not yet defined. Here, we show that overexpression and sequestration of miR‐203 in HCT‐116 and HT‐29 human CRC cells reduces and enhances their stemness, respectively. We also show that GATA‐binding factor 6 (GATA6) is a direct target of miR‐203. Our results indicate that upregulated expression of this transcription factor not only restores the self‐renewal abilities of miR‐203‐overexpressing HCT‐116 and HT‐29 cells but also promotes the stemness properties of their parental counterparts. More important, we show that silencing the expression of either LRH‐1 or Hes‐1 is sufficient to diminish the stemness‐promoting effects of GATA6 in human CRC cells. Together, our findings delineate the stemness‐inhibitory mechanism of miR‐203 in human CRC cells and suggest that this miR is a potential therapeutic agent for colorectal cancer.

BACKGROUND: Both mitochondria and the Nrf2/Keap1 pathway are targets of cancer therapy. Reactive oxygen species released from mitochondria can activate Nrf2, and the Nrf2/Keap1 pathway affects glycolysis, oxidative phosphorylation, mitochondrial biogenesis and mitophagy. OBJECTIVE: This study investigates the associations between the expressions of proteins in the Nrf2/Keap1 pathway and those related to mitochondrial function and glycolysis in colorectal cancer (CRC) with or without metastasis. METHODS: The protein levels of HO1, Nrf2, Keap1, Bach1, p21, p62, NRF1, LC3, ATP5B, HSP60 and GAPDH in the normal and tumor tissues of 60 CRC subjects were determined by Western blot. RESULTS: The Keap1 protein levels, the ATP5B/HSP60 ratio and the BEC index were higher in the tumor than in the normal tissues of CRC with or without metastasis. The following clusters were found in the dendrogram: Nrf2 and p21 with ATP5B and GADPH in all the tissues and with NRF1 in all except the tumor tissues with metastasis; Bach1 with ATP5B and GAPDH in the tumor tissues; Keap1 with p62 in all the tissues, with LC3 in the tumor tissues and with NRF1 and HO1 in the tumor tissues with metastasis. CONCLUSIONS: Nrf2, Keap1, Bach1 and p21 have the association with the proteins related to mitochondrial functions different among the tissues of CRC with or without metastasis. [ABSTRACT FROM AUTHOR]

HEME oxygenase ,TUMOR growth ,GENE expression ,MESSENGER RNA ,POLYMERASE chain reaction - Abstract
Heme oxygenase 1 (Hmox1) plays an important role in the growth and spread of tumor, and its expression is regulated positively by Nrf2 [nuclear factor (erythroid-derived 2)-like 2; NFE2L2] and negatively by kelch-like ECH-associated protein 1 (Keap1) and by BTB and CNC homology 1 (Bach1). Both Hmox1 and Nrf2 contribute to distant metastasis of cancer. The mRNA levels of Hmox1, Nrf2, Keap1, and Bach1 in the tumor and normal tissues of 84 subjects with colorectal cancer (CRC) were determined by real-time polymerase chain reaction. The tumor had lower Hmox1 but higher Bach1 mRNA levels than the normal tissue. The correlations of Hmox1 with components of the Nrf2 pathway were not significant in the tumor tissue of CRC subjects with distant metastasis. The ratio of Hmox1/Nrf2 mRNA level (by percentage) in the tumor tissue was lower in the subjects with distant metastasis (97.4% (84.4–111.1%)) than in those without (101.0% (92.7–136.5%)) and was a predictor for distant metastasis in CRC (odds ratio: 0.83; 95% confidence interval: 0.68–0.97) along with serum carcinoembryonic antigen (1.0027, 1.006–1.064). The mRNA level of Hmox1 in the tumor tissue of CRC is not correlated with that of the Nrf2 pathway molecules, and its ratio to the Nrf2 level may be useful for suggesting distant metastasis in CRC.

The correlations of pretreatment serum concentrations of proinflammatory cytokines such as interleukin (IL)-1 β, IL-6, and tumor necrosis factor- α (TNF α) with the clinicopathologic features and progression of colorectal cancer (CRC) were investigated. The pretreatment serum levels of IL-1 β, IL-6, and TNF α were measured in 164 CRC patients before treatment. The relationships between changes in proinflammatory cytokine and C-reactive protein (CRP) levels and both clinicopathologic variables and disease progression were examined by univariate and multivariate analysis. Advanced tumor stage was associated with a poorer histologic differentiation, higher CRP level, lower albumin level, and inferior progression-free survival rate (PFSR). Furthermore, high levels of CRP (>5 mg/L) were associated with proinflammatory cytokine intensity, defined according to the number of proinflammatory cytokines with levels above the median level (IL-1 β ≥10 pg/mL; IL-6 ≥ 10 pg/mL; and TNF α ≥55 pg/mL). Under different inflammation states, proinflammatory cytokine intensity, in addition to tumor stage, independently predicted PFSR in patients with CRP <5 mg/L, whereas tumor stage was the only independent predictor of PFSR in patients with CRP ≥5 mg/L. Proinflammatory cytokine intensity and the CRP level are clinically relevant for CRC progression. Measurement of IL-1 β, IL-6, and TNF α serum levels may help identify early cancer progression among patients with CRP <5 mg/L in routine practice. [ABSTRACT FROM AUTHOR]

- Abstract
Limited studies have assessed the associations of pretreatment serum glutamine level with clinicopathological characteristics and prognosis of colorectal cancer (CRC) patients. This study focuses on clarifying the clinical significance of baseline serum glutamine level in CRC patients. We retrospectively examine 123 patients with newly diagnosed CRC between 2009 and 2011. The associations of pretreatment serum glutamine level with clinicopathological characteristics, proinflammatory cytokines, overall survival (OS), and progression-free survival (PFS) were analyzed. We executed univariate and multivariate analyses to assess the associations between serum glutamine level and clinicopathological variables able to predict survival. Low glutamine levels were associated with older age, advanced stage, decreased albumin levels, elevated carcinoembryonic antigen levels, higher C-reactive protein levels, higher modified Glasgow prognostic scores, and higher proinflammatory cytokine levels. Furthermore, patients with low glutamine levels had poorer OS and PFS than those with high glutamine levels (p < 0.001 for both). In multivariate analysis, pretreatment glutamine level independently predicted OS (p = 0.016) and PFS (p = 0.037) in CRC patients. Pretreatment serum glutamine level constitutes an independent prognostic marker to predict survival and progression in CRC patients. [ABSTRACT FROM AUTHOR]

Background and Objectives: To examine the relationship between malnutrition criteria, serum glutamine and arginine concentrations, and clinicopathological features in Taiwan colorectal cancer patients.Methods and Study Design: Three malnutrition criteria (body weight loss>5% over past 6 months, body mass index (BMI)<18.5 kg/m2, and hypoalbuminemia) and serum levels of glutamine and arginine were measured in 164 colorectal patients. Malnutrition status and serum glutamine and arginine concentrations were tested for their association with each other, as well as with the clinicopathological variables.Results: Of the 164 patients, 38 (23.5%) had body weight loss, 19 (11.9%) had low BMI, and 57 (35.8%) had hypoalbuminemia. The univariate analysis showed hypoalbuminemia was correlated with advanced tumour stage, lower concentrations of glutamine, higher C-reactive protein level, and progression-free survival rate. Univariate analysis also showed glutamine levels were lower in advanced tumour stage, but arginine levels were not associated with any clinicopathologic variables. Neither the nutrition criteria used in this study nor glutamine and arginine levels were correlated with hospital stay or progression-free survival rate in multivariate analysis.Conclusions: Different nutrition assessment criteria produced different malnutrition rates in colorectal cancer patients; however, pre-treatment malnourished status and low serum glutamine and arginine concentrations were not correlated with hospital stay and progressionfree survival rate.

- Abstract
Objectives: This study was conducted to evaluate the safety and efficacy of single sebacoyl dinalbuphine ester (SDE) injection (150 mg/2 mL) when administered intramuscularly to patients who underwent hemorrhoidectomy for postoperative long-acting analgesia., Methods: A total of 221 patients scheduled for hemorrhoidectomy from 6 centers in Taiwan were randomly divided into SDE group and placebo group, and received the treatment, vehicle or SDE, 1 day before the surgery. Visual analogue scale (VAS) was recorded up to 7 to 10 days. Pain intensity using VAS AUC through 48 hours after surgery was calculated as the primary efficacy endpoint., Results: Area under the curve of VAS pain intensity scores (VAS AUC) through 48 hours after hemorrhoidectomy was significantly less in SDE group than those in placebo group (209.93 vs. 253.53). VAS AUC from the end of surgical procedure to day 7 was also significantly different between SDE and placebo group (630.79 vs. 749.94). SDE group consumed significantly less amount of other analgesics, such as PCA ketorolac and oral ketorolac. Median time from the end of surgery to the first use of pain relief medication was also shortened in the placebo group than in the SDE group. Most adverse events were assessed as mild and tolerable in both groups., Discussion: SDE injection demonstrated an extended analgesia effect, with a statistically significant reduction in pain intensity through 48 hours and 7 days after hemorrhoidectomy.
