Breast cancer resistance protein (Bcrp/Abcg2) localized at the blood-brain barrier (BBB) limits permeability into the brain of many xenobiotics, including pharmacological agents. Peroxisome proliferator-activated receptor α (Pparα), a ligand-activated transcription factor, primarily involved in lipid metabolism, has been shown to regulate the functional expression of Bcrp in human cerebral micr...
Peroxisome proliferator-activated receptor alpha (PPARα) is a nuclear hormone receptor involved in the transcriptional regulation of lipid metabolism, fatty acid oxidation, and glucose homeostasis. Its activation stimulates antioxidant enzymes such as catalase, whose expression is decreased in aged human skin. Here we investigated the expression of PPARα in aged and ultraviolet (UV)-irradiated ...
Brown adipocytes and myocytes develop from a common adipomyocyte precursor. PPARα is a nuclear receptor important for lipid and glucose metabolism. It has been suggested that in brown adipose tissue, PPARα represses the expression of muscle-associated genes, in this way potentially acting to determinate cell fate in brown adipocytes. To further understand the possible role of PPARα in these pro...
Type 2 diabetes mellitus (T2DM) is a chronic metabolic disease characterized by lack of insulin and high glucose levels. T2DM can cause bone loss and fracture, thus leading to diabetic osteoporosis. Promoting osteogenic differentiation of osteoblasts may effectively treat diabetic osteoporosis. We previously reported that Sirtuin 1 (Sirt1), a NAD+-dependent deacetylase, promotes osteogenic diff...
زمینه و هدف: پروتئین فعال کننده نوتروفیلی (hp-nap) یک آنتی ژن حفاظتی و یک فاکتور بیماری زایی اصلی هلیکوباکتر پیلوری است. تحریک سیستم ایمنی جهت درمان این باکتری نقش کارآمد دارد. هدف مطالعه حاضر بررسی اثر پروتئین نوترکیب فعال کننده نوتروفیلی از هلیکوباکتر پیلوری بر میزان تکثیر و بقای ماکروفاژهای صفاقی موشی مدل بالب سی می باشد. مواد و روش ها: طی یک مطالعه تجربی – آزمایشگاهی، پروتئین نوترکیب hp-nap...
Widely varied compounds, including certain plasticizers, hypolipidemic drugs (e.g., ciprofibrate, fenofibrate, WY-14643, and clofibrate), agrochemicals, and environmental pollutants, are peroxisome proliferators (PPs). Appropriate dose of PPs causes a moderate increase in the number and size of peroxisomes and the expression of genes encoding peroxisomal lipid-metabolizing enzymes. However, hig...
Ventral tegmental area dopamine neurons control reward-driven learning, and their dysregulation can lead to psychiatric disorders. Tonic and phasic activity of these dopaminergic neurons depends on cholinergic tone and activation of nicotinic acetylcholine receptors (nAChRs), particularly those containing the β2 subunit (β2*-nAChRs). Nuclear peroxisome proliferator-activated receptors type-α (P...
The peroxisome proliferator-activated receptor-α (PPARα) plays a key role in lipid metabolism and energy combustion. Chronic activation of PPARα in rodents leads to the development of hepatocellular carcinomas. The ability of PPARα to induce expression of its target genes depends on Mediator, an evolutionarily conserved complex of cofactors and, in particular, the subunit 1 (Med1) of this compl...
Metabolic reprogramming plays a crucial role in the development of cancer. The aim of this study was to explore the effect of fenofibrate, an agonist of peroxisome proliferator-activated receptor alpha (PPARα), on gene expression profiles of mitochondrial energy metabolism. Our results showed that PPARα expression was negatively correlated with tumor progression in an oral cancer mouse model. A...
یکی از ویژگی های ویروس hsv-1 توانایی آن در خفته شدن در میزبان برای تمام طول زندگی میزبان و عودهای وقت و بی-وقت عفونت است. طی فرایند خفتگی ژن های فاز لیتیک بیان نمی شوند و در عوض ترانسکریپت lat به همراه dna ویروس قابل شناسایی است. پس از ساخته شدن lat طی فرایند اسپلایسینگ تعدادی ترانسکریپت کوچک تر به همراه اینترون های وابسته در هسته مجتمع می گردد. خاموش شدن ژن های آلفا عامل اصلی ایجاد خفتگی است. ...
