Elevated Farnesoid X Receptor (FXR) and Retinoid X Receptors (RXRs) expression is associated with less tumor aggressiveness and favourable prognosis in patients with pancreatic adenocarcinoma.

Abstract：

UNLABELLED:Farnesoid X Receptor (FXR) and its co-partners Retinoid X Receptors (RXRs) are considered to participate in crucial biochemical and cellular processes, being involved in the pathogenesis of several diseases, including cancer. The present study aimed to evaluate the clinical significance of FXR alone and in conjunction with RXRs expression, in pancreatic adenocarcinoma. FXR, RXR-α, -β and -γ protein expression was assessed immunohistochemically on tumoral samples of 55 pancreatic adenocarcinoma cases and was statistically analyzed with clinicopathological characteristics, tumor proliferative capacity and patients' survival. Enhanced FXR expression was borderline associated with earlier histopathological stage (p=0.054). Concomitant elevated FXR/RXR-α expression was significantly associated with decreased tumor histological grade (p=0.017), while concomitant enhanced FXR/RXR-β and FXR/RXR-γ expression with earlier histopathological stage (p=0.017 and p=0.004, respectively) and smaller tumor size (p=0.037 and p=0.005, respectively). Concomitant enhanced FXR/RXR-γ expression was additionally significantly associated with the absence of lymph node metastases (p=0.018). Pancreatic adenocarcinoma patients with enhanced FXR, FXR/RXR-β or -γ expression showed significantly longer survival times compared to those with low expression (p=0.013, p=0.021 and p<0.001, respectively). In multivariate analysis, FXR and FXR/RXR-γ expression were identified as independent prognostic factors (p=0.044 and p=0.001, respectively). CONCLUSION:The present study suggested that FXR and RXRs were implicated in pancreatic malignant disease progression, reinforcing their utility as clinical markers for patients' management and prognosis, as well as targets for potential therapeutic interventions. KEYWORDS:FXR, RXR, pancreatic adenocarcinoma, immunohistochemistry, clinicopathological parameters, patients' survival.
