Abstract Background Gastric cancer (GC) remains an important worldwide. Further understanding of the molecular mechanisms gastric carcinogenesis will enhance diagnosis and treatment GC. Methods The expression DLEU2 ETS2 was analyzed in several GC cell lines using GEPIA online analyze, qRT-PCR immunohistochemistry. biological behavior cells detected by CCK8, clone formation, transwell, wound hea...

One mechanism by which endogenous microRNAs (miRNAs) function is to suppress translation of target mRNAs. Computational identification of target mRNAs is hampered by the partial complementarity between miRNAs and their targets and the lack of in vivo approaches to identify targets. Here, we identify mRNAs that are regulated by specific endogenous miRNA by detecting shifts in individual mRNA abu...

Inactivation of the von-Hippel Lindau ( VHL ) tumor suppressor gene occurs in 90% of human clear cell renal cell carcinomas (ccRCC) and leads to the stable expression of the hypoxia-inducible factors HIF1α and HIF2α. The constitutive expression of HIF1α in a majority of VHL defi cient tumors is counterintuitive, given that HIF1α functions as a tumor suppressor in ccRCC, whereas HIF2α clearly en...

MicroRNAs (miRNAs) are present in human plasma and known as a non-invasive biomarker for cancer detection. Our study was designed to identify plasma miRNAs specific for rheumatoid arthritis (RA) by a comprehensive array approach. We performed a systematic, array-based miRNA analysis on plasma samples from three RA patients and three healthy controls (HCs). Plasma miRNAs with more than four time...

Clear cell renal cell carcinoma (ccRCC), the most frequent subtype of renal cell cancer, is characterized by mutation of the von Hippel-Lindau (VHL) tumor suppressor gene, which results in stabilization of hypoxia-inducible factor (HIF) α proteins. In this issue of Cancer Discovery, Mathew and colleagues report that miR-30c-2-3p and miR-30a-3p downregulation in ccRCC promotes increased expressi...

and CD24 –/lo have aberrant expression of miRNAs and much greater self-renewal activity, proliferation and tumor initiation than other cancer cells. The high expression of miR-21, miR-181a and miR-181b has been observed in breast CSCs; however, these cells express very low levels of let-7, miR-34, miR-200, miR-29, miR-30a and miR-93. Similar to breast CSCs, prostate CSCs express a very low leve...

PURPOSE Epithelial ovarian cancer (EOC) is one of the most lethal gynecologic diseases, with survival rate virtually unchanged for the past 30 years. EOC comprises different histotypes with molecular and clinical heterogeneity, but up till now the present gold standard platinum-based treatment has been conducted without any patient stratification. The aim of the present study is to generate mic...

As crucial small regulatory molecules, serum microRNAs (miRNAs) have been widely identified as potential noninvasive biomarkers. To survey and identify serum miRNAs associated with workers who had experienced injury to their nerve system from carbon disulfide (CS2), we profiled abnormally expressed miRNAs using the microarray technique and further performed qRT-PCR validation in case and contro...

Lung cancer is one of the most common deadly diseases worldwide, most of which is non-small cell lung cancer (NSCLC). The epidermal growth factor receptor (EGFR) mutant NSCLCs frequently respond to the EGFR tyrosine kinase inhibitors (EGFR-TKIs) treatment, such as Gefitinib and Erlotinib, but the development of acquired resistance limits the utility. Multiple resistance mechanisms have been exp...
