miR-146a : یک سرکوبگر احتمالی تومور در مالتیپل میلوما

mir-۱۴۶a : یک سرکوبگر احتمالی تومور در مالتیپل میلوما

چکیده سابقه و هدف میکروrnaها با تنظیم بیان ژن در سطح پس از رونویسی، نقش کلیدی را در کنترل پاسخ­های ایمنی، التهاب، رشد و مرگ سلولی ایفا می­نمایند. بسیاری از میکروrnaها به عنوان انکوژن، سرکوبگر تومور و تعدیل کننده رشد سلول­های بنیادی سرطانی عمل می­نمایند. mir-146a ، از میکروrnaهایی است که نقش مهمی در بروز سرطان­ها ایفا نموده و می­تواند به عنوان محرک رشد و یا سرکوبگر تومور عمل کند. مطالعه حاضر به­...

miR-146a in gastric cancer Clinical significance of miR-146a in gastric cancer cases

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...

miR-146a and miR-196a2 polymorphisms in ovarian cancer risk.

We investigated the relationship between miR-146a and miR-196a2 genetic polymorphisms and development of ovarian cancer in a Chinese population. A total of 134 patients and 227 control subjects were involved in our study between January 2012 and October 2014 from China-Japan Union Hospital of Jilin University. Genotyping of miR-146a and miR-196a2 was accomplished by polymerase chain reaction co...

Effect of miR-146a and miR-155 on cardiac xenotransplantation

The aim of the present study was to investigate the expression levels of miR-146a and miR-155 in a cardiac xenograft model treated with the immunosuppressant FK506, and to construct lentiviral vectors to further study the roles of miR-146a and miR-155 in cardiac xenotransplantation. Expression levels of miR-146a and miR-155 were examined by quantitative polymerase chain reaction analysis and pr...

Epigenetic control of epileptogenesis by miR-146a

Treatments for epilepsy, a multi-etiology brain disorder affecting over 50 million people worldwide, are so far limited to drugs which provide mere symptomatic control of seizures, have many adverse effects and are ineffective in up to 40% of patients [1]. These considerations urge on the development of therapies with disease-modifying properties targeting the key pathogenic mechanisms generati...
