cefe.cnrs-mop.fr Under natural selection, individuals tend to adapt to their local environmental conditions, resulting in a pattern of LOCAL ADAPTATION (see Glossary). Local adaptation can occur if the direction of selection changes for an allele among habitats (antagonistic environmental effect), but it might also occur if the intensity of selection at several loci that are maintained as polym...
Stimulation of μ-opioid receptors (OPRMs) brings powerful pain relief, but it also leads to the development of tolerance and addiction. Ensuing withdrawal in abstinent patients manifests itself with severe symptoms, including cold hyperalgesia, often preventing addicted patients from successfully completing the rehabilitation. Unsurprisingly, OPRMs have been a central point of many studies. Non...
Social mammals engage in affiliative interactions both when seeking relief from negative affect and when searching for pleasure and joy. These two motivational states are both modulated by μ-opioid transmission. The μ-opioid receptor (MOR) system in the brain mediates pain relief and reward behaviors, and is implicated in social reward processing and affiliative bonding across mammalian species...
Background and Object Whether opioid-receptor mu 1 (OPRM1) A118G polymorphism (rs1799971) is associated with nicotine dependence is controversial. We analyzed the combined results from published studies of this possibility. Methods Literature reviews were performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Web of Science, Chinese Nati...
BACKGROUND AND PURPOSE Despite moderate heritability, the phenotypic heterogeneity of ischemic stroke has hampered gene discovery, motivating analyses of diagnostic subtypes with reduced sample sizes. We assessed evidence for a shared genetic basis among the 3 major subtypes: large artery atherosclerosis (LAA), cardioembolism, and small vessel disease (SVD), to inform potential cross-subtype an...
مطالعات انجام شده روی مکانیسمهای تکوینی و تکاملی گلبولهای قرمز منجر به دستیابی بشر به مفاهیم پایه و مهمی در ارتباط با مکانیسمهای عمومی تنظیم بیان ژن وشکل گیری بافتها شده است. تمایز اختصاصی به رده ارتیروئید و هر رده دیگری، شدیداً وابسته به تنظیم در سطح بیان ژن و فاکتورهای کنترلی خاص نظیر سیتوکین ها، فاکتورهای نسخه برداری ویژه، عناصر کنترل کننده چرخه سلولی، تکثیر،آپوپتوز و عناصر سیگنالینگ داخل سلو...
