Rationale: Despite improved understanding of the underlying genetics, pulmonary arterial hypertension (PAH) remains a severe disease. Extensive remodeling of small pulmonary arteries, including proliferation of pulmonary artery smooth muscle cells (PASMCs), characterizes PAH. MicroRNAs (miRNAs) are noncoding RNAs that have been shown to play a role in vascular remodeling. Objective: We assessed...

MiR-145 could regulate tumor growth, apoptosis, migration, and invasion. In our present study, we investigated its role in epithelial-mesenchymal transition (EMT). Expression of miR-145 was decreased in breast tumor tissues at T3&4 stages in comparison with those at T1&2. Over-expression of miR-145 mimics enhanced protein levels of E-cadherin and dampened those of α-SMA and Fibronectin, indicat...
UNLABELLED Triple-negative (ER(-), HER2(-), PR(-)) breast cancer (TNBC) is an aggressive disease with a poor prognosis with no available molecularly targeted therapy. Silencing of microRNA-145 (miR-145) may be a defining marker of TNBC based on molecular profiling and deep sequencing. Therefore, the molecular mechanism behind miR-145 downregulation in TNBC was examined. Overexpression of the lo...
Colorectal cancer (CRC) is one of the leading causes of cancer-associated mortality worldwide. There is increasing evidence that microRNAs (miRNAs) are involved in development and progression of colorectal carcinoma. miR-145 is a tumor suppressor and has been confirmed as a negative regulator of colorectal cancer. Although multiple target genes have been identified for miR-145, the molecular me...
Recent studies have demonstrated functions of miR-145 in vascular smooth muscle cells (VSMCs) phenotypes and vascular diseases. In this study, we aim to determine whether CD40 is involved in miR-145 mediated switch of VSMC phenotypes. In cultured VSMCs, the effects of miR-145 and CD40 on TNF-α, TGF-β, and Homocysteine (Hcy) induced cell proliferation were evaluated by over-expression of miR-145...
MiR-145 inhibits the epithelial-to-mesenchymal transition via targeting ADAM19 in human glioblastoma
In recent years, increasing studies demonstrated that miR-145 plays a tumor suppressor role in many human cancers. In the present study, we evaluated the expression of miR-145 and A Disintegrin and Metalloproteinase 19 (ADAM19) in glioblastoma multiforme (GBM) tissues and cells. Furthermore, we investigated the mechanisms underlying miR-145/ADAM19-induced GBM biology. Here, we found that miR-14...
In the present study, we sought to elucidate the effect of miR‑145 on glioma cell progression and its mechanisms of action. We examined the effects of miR‑145 on proliferation and invasion of U87 glioma cells and on capillary tube formation. Our data show that restoration of miR‑145 in U87 glioma cells significantly reduced their in vitro proliferation, invasion and angiogenesis. However, decre...
Venous thromboembolism (VTE), the third leading cardiovascular complication, requires more understanding at molecular levels. Here, we have identified miR-145 as a key molecule for regulating thrombus formation in venous thrombosis (VT) employing network based bioinformatics approach and in vivo experiments. Levels of miR-145 showed an inverse correlation with thrombus load determined by coagul...
