BACKGROUND/AIMS MicroRNAs (miRNAs) play important roles in tumorigenesis. We investigated the roles and mechanisms of miR-138 in human non-small cell lung cancer (NSCLC). METHODS The expression of miR-138 was first examined in NSCLC cell lines and tumour tissues by real-time PCR The in vitro and in vivo functional effect of miR-138 was examined further. A(More)
CONTEXT MicroRNAs (miRNAs) are strongly implicated in many cancers, including papillary thyroid carcinoma (PTC), which is the most common malignancy in thyroid tissue. Recently, miRNA-155 (miR-155) has been proved to play a substantial role in liposarcoma and breast cancer, but its functions in the context of PTC remain unknown. OBJECTIVES The objective(More)
Coronary artery disease (CAD) is associated with high mortality and occurs via endothelial injury. Endothelial progenitor cells (EPCs) restore the integrity of the endothelium and protect it from atherosclerosis. In this study, we compared the expression of microRNAs (miRNAs) in EPCs in atherosclerosis patients and normal controls. We found that miR-221(More)
Bone marrow stromal stem cells (MSCs), which normally differentiate into mesenchymal derivatives, have recently reported to trans-differentiate into neurons. However, the findings from different groups and interpretations have been challenged. The purpose of this paper is to re-evaluate the phenomenon of neuronal trans-differentiation of MSCs and compare(More)
Breast cancer remains the leading cause of cancer mortality in females, and about 70% of the primary breast cancer patients are diagnosed ERα-positive, which is the most common type of breast cancer. MicroRNA-34a (miR-34a) has been shown to be a master regulator of tumor suppression in many types of cancers including breast cancer. However, the role of(More)
The long noncoding RNA H19 is overexpressed in many cancers and acts as an oncogene. Here, we investigated the role of H19 in thyroid carcinogenesis and its relation to microRNA miR-17-5p and its target gene YES1. H19 expression was higher in tumor samples and in thyroid cancer cell lines than nontumor tissues and normal thyroid cells. H19 knockdown and(More)
BACKGROUND/AIMS There is growing evidence that some cancer progression is closely associated with beta- adrenoreceptors (β-ARs). However, the underlying mechanisms for β-ARs mediated proliferation of pancreatic cancer cell are poorly understood. In the current study, we evaluated the possible function of β-ARs on the proliferation of human pancreatic ductal(More)
Mounting evidence has shown that microRNAs (miRNAs) are implicated in carcinogenesis and can function as oncogenes or tumor suppressor genes in human cancers. Recent profile studies of miRNA expression have documented a deregulation of miRNA (miR-214) in hepatocellular carcinoma (HCC). However, its potential functions and underlying mechanisms in(More)
BACKGROUND Glucokinase (GCK) is the key glucose phosphorylation enzyme which has attracted considerable attention as a candidate gene for type 2 diabetes (T2D) based on its enzyme function as the first rate-limiting step in the glycolysis pathway and regulates glucose-stimulated insulin secretion. In the past decade, the relationship between GCK and T2D has(More)
Indoleamine 2,3-dioxygenase (IDO) converts tryptophan to l-kynurenine, and it is noted as a relevant molecule in promoting tolerance and suppressing adaptive immunity. In this study, to investigate the effects of IDO in carbon tetrachloride (CCl(4) )-induced hepatitis model, the levels of IDO enzymic activities in the mock group, the control group and the(More)
