Objective(s) Curative treatment of breast cancer patients using chemotherapy often fails as a result of intrinsic or acquired resistance of the tumor to the drug. ERK is one of the main components of the Ras/Raf/MEK/ERK cascade, which mediates signal from cell surface receptors to transcription factors to regulate different gene expression. In this study, cytotoxicity and the expression of Erk...
Objective(s): Naringin has been reported to regulate bone metabolism. However, its effect on osteogenesis remains unclear. The aim was to investigate the effect of naringin on osteogenic differentiation of human bone marrow mesenchymal stem cells (hBMSCs) through the activation of the ERK signaling pathway in osteogenic differentiation. Materials and Methods: Annexin V-FITC assay and MTT assay ...
In this research we used forward-backward sweep method(FBSM) in order to solve optimal control problems. In this paper, one hybrid method based on ERK method of order 4 and 5 are proposed for the numerical approximation of the OCP. The convergence of the new method has been proved .This method indicate more accurate numerical results compared with those of ERK method of order 4 and 5 for solvin...

Introduction: Bisphenol A (BPA) is a toxic chemical that is used as a monomer in the production of plastic products. The BPA has an endocrine-disrupting effect and induces damage to the nervous system. Crocin, an active ingredient of Crocus sativus L. has neuroprotective effects. Therefore, this study aimed to evaluate crocin’s effects on BPA-induced memory impairment in rats and the levels ...
Objective(s): Crocus sativus L. and its active constituent, crocin, have neuroprotective effects. The effects of crocin on memory impairment have been mentioned in studies but the signaling pathways have not been evaluated. Therefore, the aim of this study was to evaluate the effects of crocin on the hyoscine-induced memory impairment in rat. Additionally, the level o...
زمینه و هدف: تا به امروز بیش از 100 نوع کیناز شناخته شده است، یکی از معروفترین آن ها خانواده بزرگ کیناز فعال شده توسط میتوژن (MAPK) است که کیناز تنظیم شده توسط پیام خارج سلولی (ERK) یکی از زیر واحدهای این خانواده می باشد؛ ERK بسیاری از عملکردهای مهم سلولی را کنترل می کنند اما تأثیر تمرین مقاومتی بر پروتئین ERK به روشنی آشکار نشده است. بنابراین هدف از تحقیق حاضر، بررسی تأثیر 8 هفته تمرین مقا...
Background: Xanthohumol is one of the main bioactive compounds extracted from the female flowers of the hops plant (Humulus lupulus L), that has been shown in several studies to have anti-cancer effects.The MAPK/ERK pathway is one of the key pathways in the regulation of gene expression, cell growth and survival. The abnormal activation of this pathway leads to the uncontrolled cell proliferati...
Background Poly cystic ovarian syndrome (PCOS) is known as a common endocrine disorder in women at reproductive ages and may cause developmental abnormality in oocyte. ERK has found as a regulator protein of Gap junctions (GJ) function and the level of exchanges between two neighbors cells, for example oocyte and surrounding cumulus cells (CCs) in the mammalian ovary. Such exchange is essential...
هدف: در این طرح تولید سلول های بنیادی جنینی هاپلوئید پارتنوژنتیک در حضور مهارکننده های مسیرهای پیام رسانی erk و tgf-β بررسی شده است. مواد و روش ها: ابتدا بلاستوسیست های پارتنوژنتیک حاصل از فعال سازی شیمیایی اووسیت ها، در محیط r2i (حاوی pd0325901 و sb431542 که بهترتیب مسیرهای پیام رسانی erk و tgf-β را مهار می کنند) کشت شدند. سپس رده های سلول های بنیادی جنینی پارتنوژنتیک در این محیط تکثیر و نگه...
