کشت گانگلیون های ریشه پشتی نخاع، یکی از روش های آزمایشگاهی مهم جهت مطالعه رشد به خارج آکسون ها، ارزیابی بقا سلول ها و مکانیسم های دخیل در مرگ سلولی می باشد. در این تحقیق، طی کشت گانگلیون های ریشه پشتی نخاع موش بالغ، به نحوه مرگ نورون های حسی و همچنین مکانیسم دخیل در مرگ این نورون ها پرداخته شد. در این پژوهش، پس از باز نمودن ناحیه پشتی موش های بالغ، یک جفت گانگلیون l5، خارج و سپس برای 24،48،72...
programmed cell death is a highly regulated form of cell death, mostly distinguished by the activation of a family of cystein-aspartate proteases (caspases) that cleave various proteins resulting in morphological and biochemical changes characteristic of this form of cell death. several recent studies have addressed the role of programmed cell death in inflammatory and chronic pain states. casp...
Purpose: The aim of this study was to investigate effects of insulin and ascorbic acid on rate of Caspase – 3 activity and DNA Laddering in hippocampus of STZ-induced diabetic rats.Materials and Methods: Thirty male Wistar rats in five groups, 6 in each group: one control group (group C) and four diabetic groups [diabetic control (group D), treatment with insulin (group I), with ascorbic acid (...
Hexameric hemoprotein (HTHP) is employed as a scaffold protein for the supramolecular assembly and activation of apoptotic signalling enzyme caspase-9, using short DNA elements modular recruitment domains. Caspase-9 on HTHP platform due to enhanced proximity followed by combinatorial inhibition at high concentrations. The domains allow reversible switching caspase-9 activity state modulatory st...
objective: this study aimed to evaluate the incidence of apoptosis in vitrified and non-vitrified human ovarian tissue by the use of morphological analysis and apoptosis assay techniques. methods: we obtained human ovarian tissue biopsies from 30 women who underwent elective caesarean sections. tissues were transported to the laboratory in pre-warmed, equilibrated leibovitz l-15 medium within 2...
Background: Gastric cancer is the most prevalent cancer with poor survival in gastrointestinal tract. Caspase 3 and 9 play an important role in the development and progression of cancer. Polymorphisms in the genes for these enzymes can affect gene activity and thus may influence susceptibility to gastric cancer. In this study, caspase 3 and 9 genes polymorphisms in patients with gastric cancer ...
Objective(s): Menopause and diabetes obviously increase the risk of cardiovascular disease in women. The aims of the present study were to evaluate the effects of ovariectomy in type 2 diabetes on the histology and expression of miRNA-29, miRNA-133, IGF-1 and Bcl-2 genes and Bcl-2 protein and caspase 3 activity in the hearts of female rats. Materials and Methods: Forty Female Wistar rats were ...
The pathogenesis of equine grass sickness (EGS) has not fully understood. A better understanding of the exact pathogenesis of diseases can help to make an accurate diagnosis. Previous studies reported some pathological damage of neuronal cells in EGS patients. In this study, primarily cytotoxicity of serum from three clinically EGS-diagnosed horses on PC12 Tet-off (PTO) cells was assessed. Subs...
Background and objectives: Ziziphora tenuior is considered as an appropriate protoscolicidal agent yet the mechanism of such effect is not known so far. The aim of this study was to evaluate the apoptotic effect of Z. tenuior extract on protoscolices of hydatid cyst. Methods: Protoscolices were collected aseptically and the Bradford test was e...
Background & Aim: Evidence suggests that apoptosis plays an important role in the aging process. Today, regular physical activity is recognized as a defense strategy in delaying aging and related diseases. This study aimed to evaluate the effect of 12 weeks of resistance training on serum levels of p53, caspase-3, and caspase-9 in sedentary elderly men. Methods: In this quasi-experimental stud...
