Increased expression of hypoxia-inducible factor-1 and connective tissue growth factor accompanied by fibrosis in the rat testis of varicocele

Blockade of Hypoxia: The Impact on Tumor Growth in an Experimental Tumor Model

Background: Tumor microenvironment is an active factor participating in immunoregulation, thereby preventing immunosurveillance and limiting the efficacy of anticancer therapies. Hypoxia as a major characteristic of solid tumors causes the expression of Hypoxia-Inducible Factor-1α (HIF-1α). This is a transcription factor that mediates hypoxic responses of tumor cells and involves in the express...

The Effect of Aerobic Training on Tumor Necrosis Factor alpha, Hypoxia-Inducible Factor-1 alpha & Vascular Endothelial Growth Factor Gene Expression in Cardiac Tissue of Diabetic Rats

Objective: The goal of this research was to determine the influence of 4 weeks aerobic training on gene expression of tumor necrosis factor alpha (TNF-α), hypoxia-inducible factor-1 alpha (HIF-1α) and vascular endothelial growth factor (VEGF) in the cardiac tissue of diabetic rats. Materials and Methods: In an experimental study, 30 male wistar rats were partitioned into three groups (n=10), d...

Effect of High-Intensity Interval Training (HIIT) on Hypoxia-Inducible Factor-1 Alpha (HIF-1α) Gene Expression in Heart Tissue and Insulin Resistance Index in Type 2 Diabetic Rats

 Background and Aim: One of the most common metabolic diseases is diabetes with hyperglycemic properties and endogenous insulin dysfunction. This study aimed to evaluate the effect of 10 weeks HIIT on HIF-1α gene expression in heart tissue of rats with type 2 diabetes. Methods: In this experimental study, 36 Wister rats with a mean weight of 200±58g were randomly assigned to control, diabetic,...

Effect of 8 weeks of Aerobic Training on Genes Expression of Hypoxia Inducible Factor HIF-1α, Vascular Endothelial Growth Factor (VEGF) and Angiostatin in Hippocampus of Male Rats with Wistar Model

Introduction: Many studies have been done about the effects of exercise on angiogenic inhibitor and stimulator factors in muscles, but few studies have examined the role of these factors in the brain especially the hippocampus. Therefore, the purpose of the current study was to investigate the effect of 8 weeks of aerobic training on gene expression of HIF-1α, VEGF and angiostatin in hippocampu...
