Pro-inflammatory cytokines are key mediators in the selective and progressive destruction of insulin-producing beta cells during type 1 diabetes development. However, the mechanisms of cytokine-induced beta cell apoptosis are not fully understood. This study demonstrates that pro-inflammatory cytokines strongly modified the expression of the anti-apoptotic protein Bcl-2 and the pro-apoptotic BH...
OBJECTIVE In this study, locally advanced bladder cancer was treated by radiation combined with cisplatin therapy and a retrospective analysis was conducted to predict the clinical response to chemoradiotherapy (CRT) based on the immunohistochemistry of apoptosis-related proteins. METHODS Sixty-two patients (median age, 68 years; range, 45-89 years) with transitional cell carcinoma of the bla...
BACKGROUND MicroRNAs (miRNAs) play vital regulatory roles in many cellular processes. The expression of miRNA (miR)-34c is highly enriched in adult mouse testis, but its roles and underlying mechanisms of action are not well understood. METHODOLOGY/PRINCIPAL FINDINGS In the present study, we show that miR-34c is detected in mouse pachytene spermatocytes and continues to be highly expressed in...
Objective: Physical activity and herbal medicine can inhabit apoptosis with two different mechanisms. The aim of this study was to assess the combined effect of regular aerobic exercise with garlic extract on heart apoptosis regulatory factors in aged rats with chronic kidney disease. Materials and Methods: In this experimental research, 42 aged male Wistar rats (48-52 weeks) were selected and...
background : biomarkers accepted for clinical use in breast cancer have low sensitivity and specificity. thus, there is a need for new markers to assist in the diagnosis, prognosis and follow-up of breast cancer patients. this study aims to investigate the diagnostic, prognostic and follow-up role of serum bcl-2, bax and p53 proteins in breast cancer patients in comparison with those of serum c...
The aim of the present study was to investigate the protective effects of N‑acetylcysteine (NAC) on contrast‑induced acute kidney injury in rats with unilateral hyronephrosis. Eighty‑two male Sprague Dawley rats were randomized to undergo sham operation (n=14) or unilateral ureteral obstruction (UUO) (n=68). After 3 weeks, the UUO animals were randomized to three groups: NAC gastric perfusion, ...
The reports show that rutin has good potentials as an anticancer agent; however, poor bioavailability due to its low aqueous solubility. present study was aimed at preparing and evaluating physicochemical properties well the activities of nanocrystals (RNs). RNs were prepared via ultrasonication method. then physicochemically characterized by conventional techniques. cytotoxic effect free on HN...
Intracerebroventricular stereptozotocin (STZ) treatment has been described as a suitable model for sporadic Alzheimer’s disease (sAD). Centrally administered STZ decreases insulin and insulin receptors in the brain and interrupts PI3/Akt signaling pathway and GSK-3β. Additionally it raises Bax/Bcl-2 ratio and prompts hippocampal apoptosis. Agmatine, a polyamine derived from L-arginin...
The aim of this study was to investigate the roles of Fas/FasL, Bcl-2/Bax, and Caspase-8 mRNA expressions in nonalcoholic fatty liver disease (NAFLD). The apoptosis percentage was measured by flow cytometry, the immunohistochemical assay was performed for the determination of Fas, FasL, Bcl-2, and Bax expressions, and a real-time polymerase chain reaction (PCR) assay was performed to detect Cas...
