MicroRNAs (miRNAs) are small, noncoding RNAs that can contribute to cancer development and progression by acting as oncogenes or tumor suppressor genes. Recent studies have also linked different sets of miRNAs to metastasis through either the promotion or suppression of this malignant process. Interestingly, epigenetic silencing of miRNAs with tumor suppressor features by CpG island hypermethyl...
Tissue-specific detargeting by miRNAs has been demonstrated to be a potent strategy to restrict adenoviral replication to cancer cells. These studies have generated adenoviruses with miRNA target sites placed in the 3'UTR of early gene products. In this work, we have studied the feasibility of providing tissue-specific selectivity to replication-competent adenoviruses through the regulation of ...
Nonsmall cell lung cancer (NSCLC) is one of the leading causes of death worldwide. TNF-related apoptosis-inducing ligand (TRAIL) has been shown to induce apoptosis in malignant cells without inducing significant toxicity in normal cells. However, several carcinomas, including lung cancer, remain resistant to TRAIL. MicroRNAs (miRNAs) are small noncoding RNAs of ∼ 24 nt that block mRNA translati...
گاز خردل (سولفور موستارد) از گروه سلاحهای شیمیایی تاول زا است. علیرغم دانش کافی در مورد آثار پاتولوژیک ناشی از مواجهه با گاز خردل، مکانیسم دقیق مولکولی عملکرد این گاز هنوز به درستی مشخص نیست. micrornaها مولکولهای rnaی غیر کدکننده ای هستند که بسیاری از مسیرهای مهم سلولی را تنظیم می نمایند. در این مطالعه، پروفایل بیانی 739 microrna، در نمونه ی سرم 43 مصدوم شیمیایی و 27 نمونه کنترل تعیین شد. آنالی...
With the advent of deep sequencing technology, a variety of miRNA length and sequence variants, termed isomiRNAs (isomiRs), have been discovered. However, the functional roles of these commonly detected isomiRs remain unknown. In this paper, we demonstrated that miRNAs regulate the expression of the HTT gene, whose mutation leads to Huntington's disease (HD), a hereditary degenerative disorder....

STUDY HYPOTHESIS DNA methylation is regulated by hypoxia in endometriosis. STUDY FINDING Hypoxia causes global hypomethylation through AU-rich element binding factor 1 (AUF1)/microRNA-148a (miR-148a)-mediated destabilization of DNA methyltransferase 1 (DNMT1) mRNA. WHAT IS KNOWN ALREADY Eutopic endometrial and ectopic endometriotic stromal cells have the same genetic background, but differ ...
BACKGROUND MicroRNAs (miRNAs) play an important role in the development and progression of acute myeloid leukemia (AML). The miR-148/152 family has been reported to be express differently in various kinds of tumors. We investigated the expression level of the miR-148/152 family in AML patients and their clinical significance. MATERIAL AND METHODS Expression levels of the miR-148/152 family in 8...
