The molecular mechanism of down-regulated microRNA-145 (miR-145) expression in lung adenocarcinoma (LAC) remains largely unknown. We hypothesized that aberrant hyper-methylation of the CpG sites silenced the expression of miR-145 in LAC. In consideration of its pivotal role in LAC development and progression, we also evaluated the clinical utility of miR-145 as a prognostic marker. We assessed ...

BACKGROUND To assess the preoperative nutritional status of patients with various disorders and to provide data for pre- and postoperative patient management plans, particularly in the elderly. There is no published information on age-matched and disease-matched preoperative nutritional/immunologic status for orthopedic patients, especially in the elderly, in Jeju. METHODS In total, 331 patie...

AIM To determine the potential roles of CD4 and microRNA (miR)-145 in gastric cancer. METHODS The levels of CD44 and miR-145 were determined in gastric cancer cells. Quantitative real-time polymerase chain reaction was used to measure to the level of CD44 mRNA. A luciferase reporter assay and western blotting were performed to examine the effect of miR-145 on CD44 expression. Tumor sphere and...

The expression of miR-145 with tumor suppressor function is decreased in lung cancer cells. Epidermal growth factor receptor (EGFR) signaling pathway is abnormally activated in lung cancer cells. It is not clear whether the EGFR signaling pathway is involved in the regulation of miR-145 expression in lung cancer. In the present study, we found that the reduction of miR-145 was associated with E...

MicroRNA (miR)-145-5p has been reported to function as a suppressor of cancer and plays an important role in cancer invasiveness. Epithelial-mesenchymal transition (EMT) is an important process in cancer invasion and migration. However, the involvement of miR-145-5p in EMT in human gastric cancer (GC) remains unclear. In this study, we aimed to investigate the molecular mechanisms by which miR-...

Multiple myeloma (MM) is a disease with an adverse outcome and new therapeutic strategies are required to combat this disease. It is well known that tumor‑suppressor microRNA (miRNA) acts as a new potential anticancer agent. Accumulating evidence showed that microRNA-145 (miR-145) is a candidate tumor suppressor miRNA. However, whether miR-145 is involved in the development and progression of M...

Background: The aim of this study was to investigate the effect of methanolic extract of Achillea millefolium L. (MEA) on the antiproliferative activity of bleomycin on human prostate cancer and normal skin cells. Materials and Methods: Human prostate cancer cell (DU-145) and human non-malignant fibroblast cell (HFFF2) were treated with MEA at various concentrations ( 20, 100, 500, 1000 and ...
