Expression of aquaporin 1, 3 and 5 in colorectal carcinoma: correlation with clinicopathological characteristics and prognosis.

ABSTRACT: Background: Prognostic biomarkers in colorectal carcinoma (CRC) have an important role in therapeutic strategy. Studies have shown that high expression of Aquaporin (AQP) is associated with poor prognosis in a variety of human tumors. AQP is involved in the initiation and development of CRC. The present study aimed to investigate the correlation between the expression of AQP1, 3 and 5 and clinicopathological features or prognosis in CRC. Methods: The AQP1, 3 and 5 expressions were analyzed based on the immunohistochemical staining of tissue microarray specimens including 112 patients with CRC between June 2006 and November 2008. The expression score of AQP (Allred_score and H_score) was digitally obtained with Qupath software. Patients were divided into high or low expression subgroups based on the optimal cut-off values. The relationship between expression of AQP and clinicopathological characteristics were evaluated using chi-square test, t-test, or one-way ANOVA, when appropriate. Survival analysis of 5-year progression free survival (PFS) and overall survival (OS) was performed with time-dependent ROC, Kaplan-Meier curves, univariate and multivariate COX analysis. Results: The AQP1, 3 and 5 expressions were associated with regional lymph node metastasis, histological grading, and tumor location in CRC, respectively (p < 0.05). Kaplan-Meier curves showed that patients with high AQP1 expression had worse 5-year PFS than those with low AQP1 expression (Allred_score: 47% vs. 72%, p = 0.015; H_score: 52% vs. 78% p = 0.006), as well as 5-year OS (Allred_score: 51% vs. 75%, p = 0.005; H_score: 56% vs. 80%, p = 0.002). Multivariate Cox regression analysis indicated that AQP1 expression was an independent risk prognostic factor (p = 0.033, HR = 2.274, HR95% CI: 1.069-4.836). There was no significant correlation between the expression of AQP3 and 5 and the prognosis. Conclusion: The AQP1, 3 and 5 expressions correlate with different clinicopathological characteristics and the AQP1 expression may be a potential biomarker of prognosis in CRC.

Project description:ObjectiveTo investigate the correlation between expression levels of adipokine and clinicopathological features and prognosis of patients with upper tract urothelial carcinoma (UTUC) based on immunohistochemical staining and bioinformatics analysis.MethodsThe 8 adipokines in this study included adiponectin (AdipoQ), leptin (LEP), interleukin (IL)-6, IL-10 and their receptors (AdipoR1, AdipoR2, LEPR, IL-6R, IL-10RA, IL-10RB). Tissue samples of patients with UTUC who underwent surgical treatment in Peking University People's Hospital from January 2014 to April 2021 were selected for immunohistochemical staining. Their quantitative gene expression data were calculated by H-Score, and relevant clinical and follow-up data were collected retrospectively. Transcription group sequencing data of UTUC patients in Gene Expression Omnibus database (GSE134292 dataset) were downloaded for comparison. Chi-square test or t-test was used to compare the expression level of adipokine between non-muscle invasive group and muscle invasive group. Univariate and multivariate Cox regression analysis and Kaplan-Meier survival curve were utilized to analyze independent predictors of overall survival (OS), disease-free survival (DFS), intravesical recurrence-free survival (IVRFS) in the both cohorts. The P < 0.05 was considered statistically significant.ResultsIn the study, 63 tissue samples of the patients with UTUC who underwent surgical treatment in Peking University People's Hospital and 57 UTUC patients in GSE134292 dataset were selected. In immunohistochemical cohort, the expressions of AdipoQ (P=0.003 6), AdipoR1 (P=0.006 5), LEP (P=0.007 7), IL-10 (P=0.006 9), and IL-10RA (P=0.008 9) were statistically higher in muscle invasive group. In GSE134292 cohort, the expressions of AdipoR1 (P=0.000 4), AdipoR2 (P=0.000 4), IL-6 (P=0.005 0), IL-10 (P=0.001 7), and IL-10RA (P=0.008 1) were statistically higher in muscle invasive group. Kaplan-Meier survival curve and multivariate Cox regression analysis showed that high IL-10RA expression was an independent predictive factor of IVRFS (P=0.044, HR=0.996, 95%CI: 0.992-0.998) in immunohistochemical cohort, which was confirmed in GSE134292 cohort (P=0.014, HR=0.515, 95%CI: 0.304-0.873).ConclusionThe expression levels of AdipoQ, AdipoR1, IL-10, and IL-10RA were correlated with tumor stage, suggesting that these adipokines played important roles in tumor progression. IL-10RA was an independent predictor of IVRFS, suggesting that IL-10 and its receptor played a critical role in tumor recurrence.

Project description:BackgroundMicroRNA (miRNA) expression is known to be deregulated in ovarian carcinomas. However, limited data is available about the miRNA expression pattern for the benign or borderline ovarian tumors as well as differential miRNA expression pattern associated with histological types, grades or clinical stages in ovarian carcinomas. We defined patterns of microRNA expression in tissues from normal, benign, borderline, and malignant ovarian tumors and explored the relationship between frequently deregulated miRNAs and clinicopathologic findings, response to therapy, survival, and association with Her-2/neu status in ovarian carcinomas.MethodsWe measured the expression of nine miRNAs (miR-181d, miR-30a-3p, miR-30c, miR-30d, miR-30e-3p, miR-368, miR-370, miR-493-5p, miR-532-5p) in 171 formalin-fixed, paraffin-embedded ovarian tissue blocks as well as six normal human ovarian surface epithelial (HOSE) cell lines using Taqman-based real-time PCR assays. Her-2/neu overexpression was assessed in ovarian carcinomas (n = 109 cases) by immunohistochemistry analysis.ResultsExpression of four miRNAs (miR-30c, miR-30d, miR-30e-3p, miR-370) was significantly different between carcinomas and benign ovarian tissues as well as between carcinoma and borderline tissues. An additional three miRNAs (miR-181d, miR-30a-3p, miR-532-5p) were significantly different between borderline and carcinoma tissues. Expression of miR-532-5p was significantly lower in borderline than in benign tissues. Among ovarian carcinomas, expression of four miRNAs (miR-30a-3p, miR-30c, miR-30d, miR-30e-3p) was lowest in mucinous and highest in clear cell samples. Expression of miR-30a-3p was higher in well-differentiated compared to poorly differentiated tumors (P = 0.02), and expression of miR-370 was higher in stage I/II compared to stage III/IV samples (P = 0.03). In multivariate analyses, higher expression of miR-181d, miR-30c, miR-30d, and miR-30e-3p was associated with significantly better disease-free or overall survival. Finally, lower expression of miR-30c, miR-30d, miR-30e-3p and miR-532-5p was significantly associated with overexpression of Her-2/neu.ConclusionsAberrant expression of miRNAs is common in ovarian tumor suggesting involvement of miRNA in ovarian tumorigenesis. They are associated with histology, clinical stage, survival and oncogene expression in ovarian carcinoma.
