Apoptosis has been proposed to play an important role in the progression of renal scarring. The mechanisms that determine whether a cell enters the apoptotic program are complex. Bax and Bcl-2 are recognized modulators of this event; their relative levels determine the fate of cells. A role for apoptosis in the progression of renal scarring in the remnant kidneys of rats submitted to subtotal n...

Background and Objective: Ghrelin has different functions in the body and one of its newly known roles is the antiapoptotic effect. However, this effect of ghrelin has not been considered in the probable hypoxia induced apoptosis in the animal lung tissue. The aim of this study was to examine the effect of ghrelin treatment on Bax/Bcl-2 gene expression in the lung tissue of rats with chronic hy...

Introduction: Diabetes is a metabolic disease, which is directly correlated with increased physical disabilities and muscle tissue damage. The present study aimed to investigate the anti-apoptotic effects of interval and continued training and crocin on diabetic rats. Methods: In this study, 49 adult rats aged eight weeks with diabetes inducaed by a high-fat di...

Introduction: Hesperidin (HES), as the most abundant flavonoid existing in the citrus, is widely used by human daily. The radio-protective effects of Hesperidin have been confirmed in various measurement systems. This study aimed to evaluate the effects of Hesperidin on the changes in the apoptosis level and expression of apoptotic genes target (bax, bcl-2 and ration of bax/bcl-2) in the periph...

background and objectives: giant cell tumor of bone (gct) is often regarded as a benign tumor, but its clinical course is unpredictable, has a high rate of recurrence, and even can metastases and transform to a malignant tumor. histological features of the tumor often could not predict its future biologic behavior, so it is just called ''giant cell tumor'' without indicating malignancy or benig...

objective(s):valproic acid (vpa), a drug used in the treatment of neurological disorders, has been shown to have cytotoxic effects on cancer cells through different mechanisms. telomerase, a ribonucleoprotein reverse transcriptase, is responsible for elongation of the telomere and is activated in cancers. a relation between telomerase activity and resistance to apoptosis has been established. t...

BACKGROUND In this study the possible relation of Bax (an apoptosis promoter) to Bcl-2 (an apoptosis inhibitor) ratio with the apoptosis co-ordination enzyme, caspase-3, in the thymus of patients with myasthenia gravis (MG) was investigated in correlation with long-term clinical prognosis. PATIENTS AND METHODS The study included 46 patients (17M/29F, mean age 36.60 +/- 16.09 yr) with MG, who ...
