MicroRNA-185 suppresses pancreatic cell proliferation by targeting transcriptional coactivator with PDZ-binding motif in pancreatic cancer.
Authors: Xia D, Li X, Niu Q, Liu X, Xu W, Ma C, Gu H, Liu Z, Shi L, Tian X, Chen X, Zhang Y Abstract The aim of the present study was to compare the expression of transcriptional coactivator with the PDZ-binding motif (TAZ) in pancreatic cancer (PC) patients, and to investigate the regulation mechanisms of TAZ in the proliferation of PC. PC tissues and matched peritumoral tissues, pancreatic juice and serum were collected from PC patients who underwent pancreatectomy between June 2012 and December 2015 at the Affiliated Hospital of Qingdao University (Qingdao, China). Pancreatic juice and serum were collected from ...

MicroRNA-216b is Down-Regulated in Human Gastric Adenocarcinoma and Inhibits Proliferation and Cell Cycle Progression by Targeting Oncogene HDAC8
We reported a significantly decreased expression of miR-216b in GC clinical specimens compared with paired non-cancerous tissues. We also observed a significant down-regulation of miR-216b expression in GC cell lines AGS and GC9811 (p < 0.0001). The introduction of miR-216b suppressed GC cell proliferation and cell cycle progression by targeting HDAC8, an oncogene shown to promote malignant tumor development with a potential miR-216b binding site in its 3′ untranslated region. HDAC8 expression was shown to be significantly increased in AGS and GC9811 cell lines (p < 0.0001) and GC tissues compared with cont...

Abstract 1214: TP53 affects SOX2 copy number alterations and expression in non-small cell lung cancer
Background: Amplifications of the transcription factor, SRY (sex determining region Y)-box 2 (SOX2), are common in non-small cell lung cancer (NSCLC). SOX2-signaling is important in maintaining the stem cell-like phenotype of cancer cells and contributes to the pathogenesis of lung cancer. TP53 is recognized as a critical regulator of stem cell pluripotency, and it is known that TP53 represses many stem cell associated genes following DNA damage. We hypothesized that SOX2 copy number alterations in lung tumors could be correlated to mutational status of TP53 gene in tumors and that TP53 played a role in regulation of SOX2 ...
