Introduction: Memory impairment is one of the complications of diabetes which may accompany with changes in expression of apoptotic and antiapoptotic genes. The aim of the present study was the evaluation of intra-hippocampal injection of aminoguanidine (AG), as an antioxidant and inducible nitric oxide synthase inhibitor, on passive avoidance memory and Bcl-2 family genes expression in diab...

Abstract This study was to investigate whether high-intensity interval training (HIIT) and saffron aqueous extract (SAE) would provide a synergistic effect improve tumor volume reduction also modulate pro- anti-apoptotic protein expression in tissue of 4T1 breast cancer-bearing mice. Female mice following induction cancer through injection cell lines were randomly divided into four groups: (1) ...

BACKGROUND The aim of this study was to examine the expressions of the bcl-2, bax, fas and c-myc apoptosis-related genes in benign prostatic hyperplasia (BPH) and prostate carcinoma (CaP) to determine whether significant differences exist within each disease and between the two groups of patients. The correlation between gene expression and tumour diameter, stage, Gleason score and serum PSA wa...

Bcl-2, Bcl-x and Bax are members fo a family of cytoplasmic proteins that influence cell survival. Whereas increased expression of Bcl-2 or Bcl-x promotes cell survival following withdrawal of survival factors, increased expression of Bax is thought to suppress survival. To investigate the potential roles of these proteins in regulating the survival of developing neurons, we compared the effect...

It is proposed that both preand postnatal as well as genetically determined abnormalities of the apoptotic processes are among factors responsible for the development of schizophrenia. The ultimate vulnerability of cells to diverse apoptotic stimuli is determined by the relative ratio of various pro-apoptotic and anti-apoptotic members of the B-cell lymphoma 2 (Bcl-2) family proteins among whic...

Introduction: To enhance radiation therapy efficiency it is crucial to implement an individual-based treatment. The aim of present study was to identify the mechanism of intrinsic apoptosis pathway on radiosensitivity and normal tissue complications caused by the radiotherapy.   Materials and Methods: radiation-induced apoptosis in periphera...

OBJECTIVE Neuroimaging findings have identified lower cortical gray matter volume in schizophrenia. Apoptosis (programmed cell death) has been proposed as a contributing pathophysiological mechanism. Levels of antiapoptotic Bcl-2 protein are low in the temporal cortex of schizophrenia patients. Bcl-2 interacts with the proapoptotic Bax protein at an upstream checkpoint to regulate the activatio...

We studied the expression of Bcl-2 family proteins during cytokine- and verotoxin (VT)-induced apoptosis in primary human umbilical vein endothelial cells (HUVECs). Our experiments demonstrated that high initial expression of Bcl-2 protein was significantly downregulated in HUVECs treated with IFN-gamma whereas TNF-alpha gave a less pronounced decrease in Bcl-2 level. Treatment with the combina...

BACKGROUND Apoptotic genes regulate apoptosis by the action of their pro- and antiapoptotic products. Among the most important proteins are p53 and Bcl-x family proteins. PATIENTS AND METHODS The differential expression of these apoptotic genes were analyzed in relation to clinicopathological criteria in women with endometrial carcinoma. Thirty-three fresh tissues and 191 paraffin-embedded ti...
