هدف از این پژوهش، بررسی صفت تعداد نتاج در هر زایش میش به‌عنوان یک صفت تولید‌مثلی مهم بود. بدین منظور از رکوردهای فنوتیپی هفت نژاد گوسفند وادی، هوی، ایسلندی، فین‌شیپ و رومانوف با باروری بالا و نژادهای تکسل و راهمنی با باروری پایین، برای مطالعه پویش ژنومی بر پایه آنالیز غنی‌سازی به منظور شناسایی مکانیسم‌‌های زیستی استفاده شد. ارزیابی پویش کل ژنومی در بسته GenABEL برنامه R انجام شد. آنالیز غنی‌ساز...
Introduction: Complex molecular pathways involve in development of different tissues such as teeth. Differential gene expression patterns during teeth development generates different tooth types. Teeth development results from interactions between oral epithelium and underlying ectomesenchyme cells with neural crest origin. Teeth development are regulated by different signaling networks. In thi...
materials and methods an oligogearray® (an oligonucleotide-based gene expression array platform) containing 126 wnt signaling pathway-related genes was used to compare gene expressions between primary hcc and adjacent non-tumorous liver tissues from 10 patients with hcc. selected differential genes were identified with real-time rt-pcr and immunohistochemistry (ihc). in particular, the protein ...
purpose a metabolic abnormality such as obesity is a major obstacle in the maintenance of the human health system and causes various chronic diseases including type 2 diabetes, hypertension, cardiovascular diseases, as well as various cancers. this study was designed to summarize the recent scientific knowledge regarding the anti-obesity role of curcumin (diferuloylmethane), which is isolated f...
Background: Survival of the conceptus is dependent on continuous progesterone signaling in the maternal decidua but how this is achieved under conditions of oxidative stress that characterize early pregnancy is unknown. Materials and Methods: Laboratory-based analysis of endometrial biopsies and primary endometrial cultures. Results: Using primary cultures, we show that modest levels of reactiv...
Objective(s): Non-invasive treatment options for retinoblastoma (RB), the most common malignant eye tumor among children, are lacking. Epithelial growth factor receptor (EGFR) accelerates cell proliferation, survival, and invasion of many tumors including RB. However, RB treatment by targeting EGFR has not yet been researched. In the current study, we investigated the effect of EGFR down-regula...
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 ...
Background and aim: Aberrant activation of diverse intracellular signaling pathways involved in differentiation, cell growth, apoptosis. These pathways include known oncogenic pathways such as Janus kinase-signal transducer and activator of transcription (JAK/STAT) pathway. The JAK/STAT signaling pathway plays an important role in many cellular functions. This pathway can be activated by variou...
Synaptic plasticity in the central nervous system (CNS) of mammals has been discussed for many years. Several forms of synaptic plasticity of mammal’s CNS have been identified, such as those that occur in long-term potentiation (LTP). Different types of LTP have been observed in distinctive areas of the CNS of mammals. The hippocampus is one of the most important areas in the CNS that pla...
Backgroud: Protein-protein interaction, plays a key role in signal transduction in signaling pathways. Different approaches are used for prediction of these interactions including experimental and computational approaches. In conventional node-edge protein-protein interaction networks, we can only see which proteins interact but ‘structural networks’ show us how these proteins inter...
