MicroRNAs (miRNAs or miRs) have been advocated as potentially robust and highly stable biomarkers of diverse disease conditions including cancer. The primary aim of this study was two-fold: i) to profile the expression levels of selected mature miRNA signature genes, such as miR-145, miR-195, miR-29 and miR-92, in a paired-study design of 20 colorectal cancer (CRC) tissues from patients versus ...
Introduction Polychlorinated biphenyls (PCBs), organic lipophilic pollutants that accumulate through diet and increase with age, have been associated polycystic ovary syndrome (PCOS) shown to affect microRNA (miRNA) expression. This work aimed determine if PCBs were circulating miRNAs whether there any correlations serum PCB/miRNA levels hormonal changes. Methods 29 non-obese PCOS healthy contr...
Recent evidence has shown that deregulated expression of members of the microRNA-29 (miR-29) family may play a critical role in human cancer, including hematological malignancies. However, the roles of miR-29 in the molecular pathophysiology of T-cell acute lymphoblastic leukemia (T-ALL) has not been investigated. Here, we show that lower levels of miR-29a were significantly associated with hig...
سرطان معده (gc) از متداولترین سرطانها و دومین سرطان منجر به مرگ و میر انسانها در اثر سرطان در جهان است. mir-372 عملکردی شبه انکومیری دارد و از طریق ژن هدفش lats2 در انواع سرطانها باعث تهاجم و نیز عدم تنظیم چرخه سلولی، آپوپتوز و تکثیر سلولی می گردد. cd44 در سرطان معده مارکر سطح سلولی بنیادی سرطانی است و باعث تهاجم و متاستاز می گردد. در این مطالعه، بیان mir-372 با ترانسداکشن لنتی ویروس حامل آن در...
We previously reported that microRNA (miR)-29b is down-regulated and has a tumor suppressor role in acute myeloid leukemia (AML). However, little is known about the mechanisms responsible for miR-29b expression downregulation in AML. In this work we screened for mutations that could affect miR-29b expression. Using Sanger sequencing, we identified a germline thymidine (T) base deletion within t...
BACKGROUND Recent studies have shown that microRNA-29 (miR-29) is significantly decreased in liver fibrosis and that its downregulation influences the activation of hepatic stellate cells (HSCs). In addition, inhibition of the activity of histone deacetylases 4 (HDAC4) has been shown to strongly reduce HSC activation in the context of liver fibrosis. OBJECTIVES In this study, we examined whet...
MicroRNA-29 (miR-29) is found to modulate hepatic stellate cells' (HSCs) activation and, thereby, reduces liver fibrosis pathogenesis. Histone methyltransferase regulation of epigenetic reactions reportedly participates in hepatic fibrosis. This study is undertaken to investigate the miR-29a regulation of the methyltransferase signaling and epigenetic program in hepatic fibrosis progression. mi...
This study aimed to investigate the potential regulatory role of miRNAs in the development of gastrointestinal tract (GIT) during the early life of dairy calves. Rumen and small intestinal (mid-jejunum and ileum) tissue samples were collected from newborn (30 min after birth; n = 3), 7-day-old (n = 6), 21-day-old (n = 6), and 42-day-old (n = 6) dairy calves. The miRNA profiling was performed us...
