Colon cancer constitutes a major challenge all over the world, which has fourth highest incidence and third mortality rate of cancers. Although therapeutic modalities have been improved in recent years, 5 y survival remains low. Oxymatrine is one main active compounds extracted from roots Sophora flavescens was found with effect for colon Recently, microRNAs recognized as type diagnostic progno...
PURPOSE MicroRNAs are approximately 22 nucleotide noncoding RNA molecules that posttranscriptionally regulate gene expression. The aim of this study was (a) to determine a role of microRNA-21 in esophageal squamous cell carcinoma and (b) to elucidate the regulation of the programmed cell death 4 (PDCD4) gene by microRNA-21. EXPERIMENTAL DESIGN MicroRNA-21 expression was investigated in 20 mat...
Osteosarcoma is the most common primary bone tumor and poor prognosis for osteosarcoma patients is mainly due to chemotherapy resistance. MicroRNAs are important to maintain pathophysiological mechanisms of cancer and influence cell sensitivity to chemotherapy. In this study, we tested the functions of microRNA-21 for malignant features as well as for drug resistance of osteosarcoma. We used No...
Interaction of microRNA-21/145 and Smad3 domain-specific phosphorylation in hepatocellular carcinoma
MicroRNAs 21 and 145 exhibit inverse expression in Hepatocellular carcinoma (HCC), but how they relate to Smad3 C-terminal and Link region phosphorylation (pSmad3C and pSmad3L) downstream of TGF-β/MAPK signaling, remains inconclusive. Our results suggest microRNA-145 targets Smad3 in HepG2 cells. Decreased tumor volume and increased apoptosis were produced in both microRNA-21 antagomir and micr...
BACKGROUND The aim of this study was to assess the differences in microRNA 21 expression among neuroblastoma (NB), embryonic tissue, and normal adrenal tissue and to identify correlations between microRNA 21 expression, the biological features of the tumor, and prognosis. METHODS A total of 70 patients with NB were selected from December 2005 and December 2007. Real-time polymerase chain reac...
OBJECTIVE Previous studies suggested that microRNA-21 may be upregulated in the liver in non-alcoholic steatohepatitis (NASH), but its role in the development of this disease remains unknown. This study aimed to determine the role of microRNA-21 in NASH. DESIGN We inhibited or suppressed microRNA-21 in different mouse models of NASH: (a) low-density lipoprotein receptor-deficient (Ldlr-/-) mi...
The management of cerebral glioma (CG) remains challenging. Recently, methods based on the study expression levels miRNAs in blood plasma have proven to be promising. volume tumor tissue is known correlate with increased microRNA-21 and -210. MicroRNA-15, -16, -34, -126 -342 are involved regulation proliferative potential, microRNA-128 metabolic activity. aim was evaluate extended protocol for ...
BACKGROUND MicroRNAs are noncoding RNA molecules that posttranscriptionally regulate gene expression. The aim of this study was to determine the role of microRNA-21 in cholangiocarcinomas and its relationship to cholangiocarcinoma RBE cell capacity for invasion and metastasis. METHODS MicroRNA-21 expression was investigated in 41 cases of cholangiocarcinoma samples by in situ hybridization an...
BACKGROUND Non-alcoholic fatty liver disease (NAFLD) is a major risk factor for hepatocellular carcinoma (HCC). However, the mechanistic pathways that link both disorders are essentially unknown. OBJECTIVE Our study was designed to investigate the role of microRNA-21 in the pathogenesis of NAFLD and its potential involvement in HCC. METHODS Wildtype mice maintained on a high fat diet (HFD) ...
