Transcriptional networks orchestrate complex developmental processes, and such networks are commonly instigated by master regulators for development. By now, considerable progress has been made in elucidating GATA factor-dependent genetic networks that control red blood cell development. Here we reported that GATA-1 and GATA-2 co-regulated the expression of two microRNA genes, microRNA-27a and ...
Dysregulation of microRNAs has been demonstrated to contribute to malignant progression of cancers, including hepatocellular carcinoma (HCC). MiR-24-3p was previously reported to be significantly upregulated in HCC. However, the potential role and mechanism of action of miR-24-3p in the initiation and progression of HCC remain largely unknown. Quantitative reverse transcription polymerase chain...
Numerous cardiac diseases, including myocardial infarction (MI) and chronic heart failure, have been associated with cardiomyocyte apoptosis. Promoting cell survival by inhibiting apoptosis is one of the effective strategies to attenuate cardiac dysfunction caused by cardiomyocyte loss. miR-24 has been shown as an anti-apoptotic microRNA in various animal models. In vivo delivery of miR-24 into...
زمینه و هدف: افزایش سن مانند بسیاری از صفات پیچیده از تعامل میان ژنوم و شرایط محیطی حاصل میگردد و اپیژنتیک بهعنوان یک مکانیسم رابط مرکزی، این دو عامل را به هم مرتبط میسازد. تاکنون مطالعاتی برای یافتن صفات وابسته به سن و نشانگرهای زیستی که پیشبینی کنندهی طول عمر و خطر بروز مرگ میباشند انجام شده، اما هنوز هیچ توافق جامعی وجود ندارد. دوقلوهای همسان یک مدل مناسب برای مطالعه تغییرات اپیژنتیک...
BACKGROUND MicroRNAs (miRNAs) are small, non-coding RNA molecules with an important role in cancer. In prostate cancer, several miRNAs are expressed abnormally suggesting they may be useful markers for diagnosis, prognosis, and potential therapeutic intervention in this disease. However, the contribution of individual miRNAs to the development and progression of this disease remains poorly unde...
background and purpose: micrornas are small non-coding rnas with 1924- nucleotides in length. up- or downregulation 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...
Background: Expression of the tumor suppressor p16 increases during aging and replicative senescence. Methodology/Principal Findings: Here, we report that the microRNA miR-24 suppresses p16 expression in human diploid fibroblasts and cervical carcinoma cells. Increased p16 expression with replicative senescence was associated with decreased levels of miR-24, a microRNA that was predicted to ass...
A screen of microRNA (miRNA) expression following differentiation in human foreskin keratinocytes (HFKs) identified changes in several miRNAs, including miR-24 and miR-205. We investigated how expression of Human Papilloma Virus Type-16 (HPV16) onco-proteins E6 and E7 affected expression of miR-24 and miR-205 during proliferation and differentiation of HFKs. We show that the induction of both m...
OBJECTIVE Ischemia hypoxia induces cardiomyocyte (CM) apoptosis in the process of acute myocardial infarction (AMI). It was showed that pro-apoptosis factor BIM participates in regulating tumor cell apoptosis under ischemia or hypoxia condition, while its role in CM apoptosis after AMI is still unclear. It was revealed that miR-24 expression was significantly reduced in myocardial tissue after ...
it was known that il-1β-induced rapid expression of mir-146a, which regulated the secretion of inflammatory chemokines in human a549 alveolar epithelial cells. however, little is known about the level of primary mir-146a and the downstream biogenesis of mir-146a in a549 cells. we examined the levels of primary mir-146a and mature mir-146a in a549 cells following treatment with pharmacological i...
