سرطان یکی از مهمترین عوامل مرگ و میر در جهان است؛ لذا توجه به پیشگیری و درمان آن از اهمیت زیادی برخوردار است. تغییرات ناهنجار اپی ژنتیک شامل متیلاسیون dna و تغییرات هیستونی نقش مهمی در سرطان زایی دارند. از آن جایی که این تغییرات نسبت به تغییرات ژنتیکی برگشت پذیرند، بالقوه درمان اپی ژنتیکی در برگرداندن برخی از این تغییرات ناهنجار کارا می باشد. آنالیز ترانسکریپتوم حاکی از رونویسی 90% ژنوم در یوکا...

MicroRNA (miRNA) have gained widespread attention for their role in diverse vascular processes including angiogenesis, apoptosis, proliferation, and migration. Despite great understanding of miRNA expression and function, knowledge of long noncoding RNA (lncRNA) molecular mechanisms still remains limited. The influence of miRNA on lncRNA function, and the converse, is now beginning to emerge. l...

Accumulating experimental studies have indicated that lncRNAs play important roles in various critical biological process and their alterations and dysregulations have been associated with many important complex diseases. Developing effective computational models to predict potential disease-lncRNA association could benefit not only the understanding of disease mechanism at lncRNA level, but al...

Genetic regulation of organisms involves complicated RNA–RNA interactions (RRIs) among messenger RNA (mRNA), microRNA (miRNA), and long non-coding (lncRNA). Detecting RRIs is beneficial for discovering biological mechanisms as well designing new drugs. In recent years, with more experimentally verified being deposited into databases, statistical machine learning, especially deep-learning-based ...

Long non-coding RNAs (lncRNAs) play key roles in various cellular contexts and diseases by diverse mechanisms. With the rapid growth of identified lncRNAs and disease-associated single nucleotide polymorphisms (SNPs), there is a great demand to study SNPs in lncRNAs. Aiming to provide a useful resource about lncRNA SNPs, we systematically identified SNPs in lncRNAs and analyzed their potential ...

Estrous cycle is one of the placental mammal characteristics after sexual maturity, including estrus stage (ES) and diestrus (DS). important in female physiology its disorder may lead to diseases, such as polycystic ovary syndrome, ovarian carcinoma, anxiety, epilepsy. In latest years, effects non-coding RNAs messenger RNA (mRNA) on estrous have started arouse much concern, however, a whole tra...

Abstract Background LncRNAs (Long non-coding RNAs) are a type of RNA molecule with transcript length longer than 200 nucleotides. LncRNA has been novel candidate biomarkers in cancer diagnosis and prognosis. However, it is difficult to discover the true association mechanism between lncRNAs complex diseases. The unprecedented enrichment multi-omics data rapid development machine learning techno...

Gastric cancer is one of the most common cancers and has the highest mortality rate worldwide. It is worthwhile to explore the mechanism of gastric cancer progression. An increasing number of studies have found that non-coding RNAs including miRNA and lncRNA play important roles in gastric cancer progression. This review summarized the role of ectopic miRNA in gastric cancer proliferation, grow...
