MicroRNA-29a (miR-29a) is a well characterized fibro-inflammatory molecule and its aberrant expression linked to variety of pathological liver conditions. The long-term effects high-fat diet (HFD) in combination with different levels EtOH consumption on miR-29a pathobiology are unknown. Mice at 8 weeks age were divided into five groups (calorie-matched plus water (CMD) as control group, HFD dis...

Hepatocellular carcinoma (HCC), the most common primary tumor of the liver, has a poor prognosis and rapid progression. MicroRNAs (miRNAs) play important roles in carcinogenesis and tumor progression. Insulin-like growth factor 1 receptor (IGF1R) is a transmembrane heterotetrameric protein that has been reported to promote transformation to malignancy and cancer cell proliferation and survival....

OBJECTIVE Vascular calcification significantly increases cardiovascular morbidity and mortality. We recently reported that the deficiency of cartilage oligomeric matrix protein (COMP) leads to vascular mineralization. We characterized the COMP-degrading metalloproteinase, a disintegrin and metalloproteinase with thrombospondin motifs-7 (ADAMTS-7). Here, we tested whether ADAMTS-7 facilitates va...

Activation of pulmonary adventitial fibroblasts plays a key role in the pulmonary vascular remodeling in hypoxic pulmonary hypertension. Previous studies showed that miRNAs participated in the regulation of fibroblast activation. This study explored the role of miR-29 in the activation of pulmonary adventitial fibroblasts and the therapeutic potential in hypoxic pulmonary hypertension. We found...

Intrauterine growth retardation (IUGR) induces metabolic syndrome, which is often characterized by insulin resistance (IR), in adults. Previous research has shown that microRNAs (miRNAs or miRs) play a role in the target genes involved in this process, but the mechanisms remain unclear. In the present study, we examined miRNA profiles using samples of skeletal muscles from both IUGR and control...

PURPOSE Circulating microRNAs (miRNA) are emerging as promising diagnostic biomarkers for colorectal cancer, but their usefulness for detecting early colorectal neoplasms remains unclear. This study aimed to identify serum miRNA biomarkers for the identification of patients with early colorectal neoplasms. EXPERIMENTAL DESIGN A cohort of 237 serum samples from 160 patients with early colorect...

Circulating microRNAs have been investigated as markers of disease severity in a variety of conditions. We examined whether circulating miR-21 and miR-29a could serve as markers of hepatic fibrosis and disease etiology in children with various liver diseases. Circulating miR-21 and miR-29a were determined in 58 children (21 female, age 0.1-17.8 (median 9.8) years)) with chronic liver disease an...

Although microRNAs (miRNAs) are increasingly linked to various physiologic processes, including hematopoiesis, their function in the myeloid development is poorly understood. We detected up-regulation of miR-29a and miR-142-3p during myeloid differentiation in leukemia cell lines and CD34(+) hematopoietic stem/progenitor cells. By gain-of-function and loss-of-function experiments, we demonstrat...

MicroRNAs are involved in a number of cellular processes; thus, their deregulation is usually apt to the occurrence of diverse diseases. Previous studies indicate that abnormally up-regulated miR-29a is associated with several diseases, such as human acute myeloid leukemia and diabetes; therefore, the proper level of miR-29a is critical for homeostasis. Herein, we observed that miR-29a was repr...
