Objective(s):An earlier meta-analysis on gene expression data derived from four microarray, two cDNA library, and one SAGE experiment had identified RGS5 as one of only ten non-housekeeping genes that were reported to be expressed in human trabecular meshwork (TM) cells by all studies. RGS5 encodes regulator of G-protein signaling-5. The TM tissue is the route of aqueous fluid outflow, and is r...
micrornas are tiny, 18-25 nucleotides in length, non-coding rna molecules preserved throughout evolution. these molecules primarily control gene expression at the post-transcriptional and transcriptional levels. micrornas control target gene expression by a phenomenon known as rna interference. rna interference based therapeutics that utilize target gene silencing/degradation by specific micror...
Introduction: MicroRNAs are small, non-coding, and protected RNA molecules that regulate gene expression after transcription by mRNA degradation or inhibition of protein synthesis. The function of these molecules is critical to many cellular processes, including growth, development, differentiation, homeostasis, apoptosis, aging, stress resistance. In addition, some diseases including cancer, a...
rna های غیرکدکننده شامل rna های غیرکدکننده ی بلند (long non-coding rnas) و micrornas در سال های اخیر در سرطان زایی بسیار مورد توجه قرار گرفته است. رونوشت های lncrnas از طریق دخالت در فرآیند هایی چون تنظیم پرتوانی سلول ها? تنظیم پیرایش های متناوب و سایر فرآیندهای مهم زیستی? در تنظیم پیچیدگی موجودات درگیر می باشند.احتمالا بیان lincrna-ror و واریانت های b21 وa1 با تومورزایی در ارتباط می باشند که ا...

Gastric cancer (GC) is one of the most common types of cancer and the second leading cause of cancer-associated mortality. Identification of novel biomarkers is critical to prolonging patient survival. MicroRNAs (miRNAs) proved to play diverse roles in the physiological and pathological state in cancers including GC. Herein we were aimed at performing a meta-analysis on miRNA profiling studies ...
exosomes, as a mediator of cell-to-cell transfer of genetic information, act an important role in intercommunication between tumor cells and their niche including fibroblasts, endothelial cells, adipocytes and monocytes. several studies have shown that tumor cells can influence their neighboring cells by releasing exosomes. these exosomes provide signaling cues for stimulation, activation, prol...
the eukaryotic complexity involves the expression and regulation of genes via rna-dna, rna-rna, dna-protein and rna-protein interactions. recently, the role of rna molecules in the regulation of genes in higher organisms has become more evident, especially with the discovery that about 97% of the transcriptional output in higher organisms are represented as noncoding rnas: rrna, snornas, trna, ...
in the retinoblastoma research, it is of great interest to identify molecular markers associated with the genetics of tumorigenesis. micrornas (mirnas) are small non-coding rna molecules that play a regulatory role in many crucial cellular pathways such as differentiation, cell cycle progression, and apoptosis. a body of evidences showed dysregulation of mirnas in tumor biology and many disease...
diffuse large b-cell lymphoma is the most common type of non-hodgkin lymphoma. micrornas (mirnas) are endogenous small rna, which can regulate gene expression at the post-transcriptional level. mirna profiling has shown a great potential as novel diagnostic and prognostic biomarkers. the present study was performed at the nemazee teaching hospital (shiraz, iran) from 2011 to 2013.the aim of thi...
