BACKGROUND AND PURPOSE MicroRNAs are small non-coding RNAs with 19-24 nucleotides in length. Up- or down-regulation of many miRNAs has been shown by stimulation of Toll-like receptors (TLRs) in the innate immune system. Up-regulation of miR-146a has been reported by both TLR and heat-killed Candida albicans. In this study, we aimed to evaluate the expression of miR-146a in cultured monocyte-der...
OBJECTIVE The function of microRNAs is highly context and cell type dependent because of their highly dynamic expression pattern and the regulation of multiple mRNA targets. MicroRNA-155 (miR-155) plays an important role in the innate immune response by regulating macrophage function; however, the effects of miR-155 in macrophages on atherosclerosis are controversial. We hypothesized that the s...
Aim: MC (continuous administration of low doses of conventional chemotherapeutics) is characterized by an excellent therapeutic index. In fact, we recently demonstrated that 24% of patients with ABC receiving daily dalteparin and oral cyclophosphamide, twice-weekly methotrexate, and daily prednisone (dalCMP) achieved clinical benefit with minimal toxicity. While there are no predictive markers ...
OBJECTIVE Myocardin, a potent transcriptional coactivator of serum response factor, is involved in vascular development and promotes a contractile smooth muscle phenotype. Myocardin levels are reduced during vascular injury, in association with phenotypic switching of smooth muscle cells (SMCs). However, the direct role of myocardin in vascular disease is unclear. APPROACH AND RESULTS We show...
Актуальність. Куркумін і кверцетин виявилися дуже ефективними проти раку молочної залози. Однак повністю їх протипухлинні механізми невідомі. У цьому дослідженні вивчено вплив куркуміну та кверцетину на ріст лінії клітин залози людини MCF-7 MDA-MB-231 шляхом регуляції miR-632 miR-137. Матеріали методи. Клітини обробляли куркуміном кверцетином у різних розведеннях протягом 24 48 годин. Життєздат...
Purpose: To investigate the effect of micro-ribonucleic acid (miR)-208a on heart failure (HF) in rats through β-catenin pathway.Methods: A total 24 specific pathogen-free female Sprague-Dawley were enrolled and randomly divided into 3 equal groups, namely, control (normal group), model, study group (miR-208a), with 8 each. Echocardiography was utilized to evaluate cardiac function, terminal deo...
The predictive value of circulating microRNAs (miRNAs) in hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) has been demonstrated in retrospective studies, but it has rarely been tested in prospective studies. In a cohort of 373 cancer-free HBV patients with a median follow-up of 4.5 years, we measured the expression of 24 retrospectively identified HCC-related miRNAs in baseline s...
Background and Aims: Cadmium (Cd) is a nephrotoxic environmental pollutant, and microRNAs have been recently investigated as potential biomarkers for the diagnosis and pathology study of certain diseases. The present study aimed to determine the protective effect of aerobic physical activity on the changes of mir-21 and mir-146-b in renal tissue caused by cadmium chloride in male rats. Materia...
فیبرز کبد یکی از پیامدهای بالینی آسیب مزمن کبد در اثر عواملی از قبیل عفونت مزمن با ویروس های هپاتیت، الکلیسم و دیگر عوامل به سلول های کبدی است که می تواند به عوارض پیچیده تری مانند سیروزکبد، ناکارایی سلولهای کبدی، سرطان کبد و نهایتا مرگ بیانجامد. فعال شدن سلول های ستارهای کبد(hscs) نقش بسیار حیاتی در شکل گیری فیبرز کبد ایفا می کند. tgf-?1 به عنوان فاکتور اصلی تحریک کننده مسئول برای فعالسازی hsc...
