CONTEXT Nonclassic congenital lipoid adrenal hyperplasia (lipoid CAH) is a recently recognized disorder caused by mutations in the steroidogenic acute regulatory protein (StAR) that retain partial function. Affected individuals can present with a phenotype of late onset adrenal insufficiency with only mild or minimally disordered sexual development. OBJECTIVES The aim was to delineate the cli...
Introduction: According to the American Society of Radiation Oncology, all patients receive radiation therapy during their illness, where radiation is delivered by the medical linear accelerator (Linac). The aim of this study was to evaluate the quality assurance (QA) of the Linac in analyzing the used dose profile in the treatment of cancer tumors. Materi...
تنش دمای پایین یکی از مهم ترین عوامل محیطی است که عملکرد گیاهان را محدود می نماید. شبکه وسیعی از ژن های مختلف در تنظیم تحمل گیاه به این تنش نقش ایفا می نمایند. در این تحقیق، نخست 921 عدد از ژن های مذکور از تحقیقات و مقالات معتبر علمی استخراج گردید و سپس به منظور شناسایی ژن های مشابه با آنها در ژنوم کامل دو گیاه سیب (malus domestica)و انگور (vitis vinifera)، توالی آمینو اسیدی این ژن ها در گیاه م...
IRF4 gene, IRF2 and IRF8 genes have been studied in sea star which is the only invertebrate, to possess these factors, playing a rôle in the immune adaptative immunity of A. rubens. Evidence of Irf4 Gene, Irf2, Irf8 Genes in an Invertebrate: The Sea Star Asterias rubens Michel Leclerc1* and Nicolas Kresdorn2 1Department of Cell Biology, Developmental Biology, Immunology, University of Orléans, ...
Imagine an intelligent life form dwelling several light years away in a Milky Way star staring curiously at a peta-scale IBM Blue Gene machine on the earth and wondering somewhat skeptically whether that infinitesimal object possesses at all any form of intelligence or computational power! Imagine the same machine at that time is spewing out calculations in the battle of the millennium, the Chi...
Estradiol (E2) is suppressed in prepubertal females exposed maternally to lead (Pb); thus, we assessed effects of Pb on ovarian steroidogenic acute regulatory protein (StAR) as a potential mechanism for this action. Adult Fisher 344 females were dosed with 12 mg of lead acetate per ml of Pb acetate (PbAc) or sodium acetate (NaAc; control), beginning 30 days prior to breeding and continuing unti...
The cholesterol transfer function of steroidogenic acute regulatory protein (StAR) is uniquely integrated into adrenal cells, with mRNA translation and protein kinase A (PKA) phosphorylation occurring at the mitochondrial outer membrane (OMM). The StAR C-terminal cholesterol-binding domain (CBD) initiates mitochondrial intermembrane contacts to rapidly direct cholesterol to Cyp11a1 in the inner...
Intracellular transport and processing of ligands is critical to the activation of signal transduction pathways that guide development. Star is an essential gene in Drosophila that has been implicated in the trafficking of ligands for epidermal growth factor (EGF) receptor signaling. The role of cytoplasmic motors in the endocytic and secretory pathways is well known, but the specific requireme...
BACKGROUND Marine organisms provide appreciable source of novel bioactive compounds with pharmacological potential. There is little information in correlation with anti-cancer activities of brittle star. In the present study, anti-neoplastic efficacy of Ophiocoma erinaceus methanol extract against human cervical cancer cells was investigated. METHODS The HeLa cells were cultured and exposed t...
Normal human cells can undergo a limited number of divisions, whereas transformed cells may have an extended life span and can give rise to immortal cells. To isolate genes involved in the immortalization process, gene expression in SV40-transformed preimmortal human fibroblasts was compared with expression in SV40-transformed immortalized fibroblasts using an mRNA differential display. We foun...
