Rationale: Aging represents a major risk factor for coronary artery disease and aortic aneurysm formation. MicroRNAs (miRs) have emerged as key regulators of biological processes, but their role in age-associated vascular pathologies is unknown. Objective: We aim to identify miRs in the vasculature that are regulated by age and play a role in age-induced vascular pathologies. Methods and Result...
هدف: سرطان پروستات دومین سرطان شایع و پنجمین عامل مرگ ناشی از سرطان مردان در سال 2012 در جهان است. مسیر pi3k/akt نقش اساسی در بیماریزایی سرطان پروستات دارد و بهدلیل نقش کلیدی این مسیر در پیشروی سرطان آن را به هدف جذابی برای استراتژی های جدید درمانی تبدیل می کند. یکی از روند های تنظیمی ژن ها، میکرو rnaها است که توانایی ویژه ای برای کنترل چندین ژن و مسیر به طور هم زمان، آن ها را کاندید قابل توج...
BACKGROUND microRNAs (miRNAs) can regulate the sensitivity of cancer cells to chemotherapy and radiotherapy. Aberrant expression of miR-195 has been found to be involved in colorectal cancer (CRC); however, its function and underlying mechanism in the radioresistance of CRC remains unclear. METHODS The levels of miR-195 and CARM1 were detected by quantitative reverse transcription-polymerase ...
Myocardial ischaemia/reperfusion (I/R)-induced remodelling generally includes cell death (necrosis and apoptosis), myocyte hypertrophy, angiogenesis, cardiac fibrosis, and myocardial dysfunction. It is becoming increasingly clear that microRNAs (miRNAs or miRs), a group of highly conserved small (∼18-24 nucleotide) non-coding RNAs, fulfil specific functions in the reperfused myocardium towards ...

Initial events after exposure determine HIV-1 disease progression, underscoring a critical need to understand host mechanisms that interfere with initial viral replication. Although associated with chronic HIV-1 control, it is not known whether interleukin-21 (IL-21) contributes to early HIV-1 immunity. Here we take advantage of tractable primary human lymphoid organ aggregate cultures to show ...
Cytomegalovirus (CMV) infection leads to notable morbidity and mortality in immunosuppressed patients. Current antiviral drugs are effective but seriously limited in their long-term use due to their relatively high toxicity. In the present study, we characterized the expression of murine CMV microRNAs (MCMV miRNAs) both in vitro and in vivo. Although 29 miRNAs were detectable during in vitro in...
