Overexpression of Citron Rho-Interacting Serine/Threonine Kinase Associated with Poor Outcome in Bladder Cancer.

ABSTRACT: Objective: Citron Rho-Interacting Serine/Threonine Kinase (CIT) was originally identified as a binding partner of active forms of the small GTPases Rho and Rac. This kinase participated in the regulation of cytokinesis and loss of CIT was associated with chromosomal instability. Here, we assume that CIT might be a potential prognostic biomarker for bladder cancer. Materials and Methods: The expression and prognostic significance of CIT mRNA were validated on 5 published microarray data sets, including 948 bladder cancer cases. To further confirm the results, we collected 54 non-carcinomatous human bladder tissue samples and 315 bladder cancer tissues from Zhejiang Provincial People's Hospital to detect the protein level of CIT based on the immunohistochemistry analysis. The Kaplan-Meier method and Cox proportional hazards regression model were used in survival analysis. Results: Analysis results showed that high CIT expression was associated with tumor size (p=0.0001), tumor grade (p<0.0001), smoking status (p=0.0143), TNM stage (p=0.0024), pathological tumor stage (p<0.0001) and aggressive phenotypes of bladder cancer. Independent and pooled survival analyses both indicated that overexpression of CIT was significantly associated with poor survival of bladder cancers. Conclusions: In conclusion, these findings indicated that overexpression of CIT was significantly associated with poor survival outcome in bladder cancers. CIT might serve as a promising prognostic biomarker and therapeutic target for bladder cancers.

Project description:Liver necroptosis of chicks is induced by selenium (Se)/vitamin E (VE) deficiencies and may be associated with oxidative cell damage. To reveal the underlying mechanisms of liver necrosis, a pool of the corn-soy basal diet (10 μg Se/kg; no VE added), a basal diet plus all-rac-α-tocopheryl acetate (50 mg/kg), Se (sodium selenite at 0.3 mg/kg), or both of these nutrients were provided to day-old broiler chicks (n = 40/group) for 6 weeks. High incidences of liver necrosis (30%) of chicks were induced by -SE-VE, starting at day 16. The Se concentration in liver and glutathione peroxidase (GPX) activity were decreased (P < 0.05) by dietary Se deficiency. Meanwhile, Se deficiency elevated malondialdehyde content and decreased superoxide dismutase (SOD) activity in the liver at weeks 2 and 4. Chicks fed with the two Se-deficient diets showed lower (P < 0.05) hepatic mRNA expression of Gpx1, Gpx3, Gpx4, Selenof, Selenoh, Selenok, Selenom, Selenon, Selenoo, Selenop, Selenot, Selenou, Selenow, and Dio1 than those fed with the two Se-supplemented diets. Dietary Se deficiency had elevated (P < 0.05) the expression of SELENOP, but decreased the downregulation (P < 0.05) of GPX1, GPX4, SELENON, and SELENOW in the liver of chicks at two time points. Meanwhile, dietary Se deficiency upregulated (P < 0.05) the abundance of hepatic proteins of p38 mitogen-activated protein kinase, phospho-p38 mitogen-activated protein kinase, c-Jun N-terminal kinase, phospho-c-Jun N-terminal kinase, extracellular signal-regulated kinase, phospho-mitogen-activated protein kinase, receptor-interacting serine-threonine kinase 1 (RIPK1), receptor-interacting serine-threonine kinase 3 (RIPK3), and mixed lineage kinase domain-like (MLKL) at two time points. In conclusion, our data confirmed the differential regulation of dietary Se deficiency on several key selenoproteins, the RIPK1/RIPK3/MLKL, and mitogen-activated protein kinase signaling pathway in chicks and identified new molecular clues for understanding the etiology of nutritional liver necrosis.
