زمینه و هدف: سرطان کولورکتال سومین دلیل مرگ و میر ناشی از سرطان در سراسر جهان است. miRNA ها، گروهی از RNA های کوچک غیر کدکننده میباشند که باعث مهار ترجمه mRNA هدف میشوند. miR-146a-5p به عنوان تومور ساپرسور میباشد که بیان نابجای آن در بسیاری از سرطان ها نشان داده شده است. در این مطالعه که یک مطالعه بنیادی و پایه بود، هدف بازگردانی سطح بیان miR-146a-5p به حد طبیعی و بررسی تاثیر آن بر بیا...
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...
PURPOSE The profiles of microRNAs change significantly in gastric cancer. MiR-146a is reported to be a tumor suppressor in pancreatic cancer, breast cancer, and prostate cancer. We investigated the clinical significance of miR-146a in gastric cancer, in particular focusing on hypothetical miR-146a target genes, such as epidermal growth factor receptor (EGFR) and interleukin-1 receptor-associate...
PURPOSE We investigated prognostic implications of microRNAs in extranodal NK/T cell lymphoma (NKTL). EXPERIMENTAL DESIGN We measured miRNA expression in NKTL tissues and cell lines, using real-time PCR, and analyzed its role in NKTL, using cell lines. RESULTS Multivariate analysis showed low miR-146a expression (P < 0.001; HR = 13.110), primary non-upper aerodigestive tract lesion (non-UAT...

مقدمه: لوسمی لنفوبلاستی حاد سلولt (t-all) حاصل نقص در بلوغ پیشتاز سلول t به سلول t بالغ می باشد. t-all یکی از انواع بدخیمی های خونی است که پیش آگهی ضعیفی دارد. به منظور دستیابی به یک روش درمانی موفق، درک و شناخت بیولوژی تکامل سلول t و مولکول هایی که در این فرایند تکاملی شرکت دارند ضروری می باشد. در این مطالعه، از رده سلولی jurkat t، که برای بررسی آزمایشگاهی t-all به عنوان سلول های مدل اثبات شده...
MicroRNAs are small non-coding RNAs that can regulate a variety of immune functions. MicroRNA146a (miRNA-146a) is regarded as crucial regulator posttranscriptional gene expression, suggesting role in autoimmune disorders. This study was performed to investigate association miRNAs-146a expression and its polymorphisms patient with Rheumatoid arthritis. The current includes 120 subjects classifie...
BACKGROUND/AIMS There have been many studies on the etiology of osteoarthritis (OA) with regard to the function of inflammatory cytokines, the process of cartilage degradation, the function of miR-146a, hypoxia stimulation and autophagy in OA chondrocytes, but there have been no reports on the relationship between miR-146a and autophagy in cartilage, especially under hypoxia. This study aimed t...
Background and purpose: Colorectal cancer (CRC) is one of the most common types of cancer. Its incidence has increased in Iran during the last 25 years. Micro-RNAs are used as new approach in cancer researches. The roles of miR-146a have been detected in different tumors. This study aimed at investigating the expression of microRNA146 in tumor tissue of colorectal adenocarcinoma in various stag...
microRNA-146a (miR-146a) has been previously implicated as an essential molecular brake, preventing immune overreaction and malignant transformation by attenuating NF-κB signaling, putatively via repression of the Traf6 and Irak1 genes. The exact contribution of miR-146a-mediated silencing of these genes to the control of immune activation is currently unknown. Therefore, we defined the role of...
