Background: A growing body of literature has revealed the effective role of miR-34a, as a tumor suppressor and regulator of expression of multiple targets in tumorigenesis and cancer progression. This study aimed at evaluating the potential effects of miR-34a alone or in combination with paclitaxel on breast cancer cells. Methods: After miR-34a transduction by lentiviral vectors in two MCF-7 an...
Objective(s):Breast cancer is an important leading cause of death from cancer. Stathmin and tau proteins are regulators of cell motility, and their overexpression is associated with the progression and bad prognosis of breast cancer. Memantine, an N-methyl-D-aspartate (NMDA) receptor antagonist, is the potential inhibitor of tau protein in neurons. This study determines the effect of memantine ...
Background & Objective: Angiopoietin-like Proteins 8 (ANGPTL8) which secreted form adipose tissue due to downstream PGC-1α pathways, is the main factor for regeneration of beta cell. The aim of this study was to investigate the effect of 4 endurance training program on PGC-1α expression in adipose tissue, ANGPTL8 serum concentration and beta cell function (HOMA.B) in diabetic rats. Materials & ...
introduction: in order to study the alterations of beta 1 and 2 integrins mrna level in rat lumbar spinal cord following the induction of chronic pain and its effect on the development of tolerance to morphine analgesia, we examined the level of expression of these genes in the presence of chronic pain, which is an inhibitor of morphine tolerance. we used induction of chronic pain alone and in ...
Background: IL-17/IL-23 axis plays an important role in the pathogenesis of several autoimmune diseases such as experimental autoimmune encephalomyelitis (EAE) and multiple sclerosis (MS). The immunomodulatory properties of ginger are reported in previous studies. Objective: To evaluate the effects of ginger extract on the expression of IL-17 and IL-23 in a model of EAE. Methods: EAE was induc...
Background: DNA vaccination with plasmid encoding bacterial, viral, and parasitic immunogens has been shown to be an attractive method to induce efficient immune responses. Bacteria of the genus Brucella are facultative intracellular pathogens for which new and efficient vaccines are needed. Methods: To evaluate the use of a DNA immunization strategy for protection against brucellosis, a pla...
Background and Aims: Prostate cancer (PCa) is one of the most common cancers among men in Iran. Since changes in the regulation of proto-oncogenes expression are the main causes of most human cancers, including PCa, evaluating the expression of marker genes can be helpful for early diagnosis of cancer and better understanding of its etiology. The present study compared c-Myc expression level in...
background: the uterus is a dynamic tissue responding to hormonal changes during reproductive cycles. as such, uterine stem cells have been studied in recent years. transcription factors oct4 and sox2 are critical for effective maintenance of pluripotent cell identity. objective: the present research evaluated the mrna expression of oct4 and sox2 in the uterine tissues of ovariectomized mice tr...
Introduction: Previous studies have shown altered levels of n-3LCPUFA in the pathophysiologcal conditions such as preeclampsia .Also elevated expression of sFlt-1 in preeclampsia plays a major role in the pathogenesis of this serious disorder especially in reduced placental oxygenation. The present study examines the hypothesis that Eicosapentaenoic acid (EPA 20:5), an omega-3 long-chain polyun...
Background: Matrix MetalloProteinases (MMPs) degrade extracellular matrix components to provide normal remodeling and contribute to pathological tissue destruction and cell migration in endometriosis. It is accepted that MMPs are resistant to suppression by progesterone in endometriotic tissues. The physiological effects of progesterone are mediated by its two progesterone receptor (PR) isoform...
