Project description:Study of transcriptional effects of Vorinostat, Sorafenib and Resveratrol on SNU-387 and HepG2/C3A hepatocellular carcinoma cell lines
Project description:Sorafenib, lenvatinib and regorafenib, the multi-RTK inhibitors with potent anti-angiogenesis effects, are currently therapeutic drugs generally recommended for the patients with advanced hepatocellular carcinoma (HCC). To date, however, there have been no published studies on the mechanism underling differential effects of the three drugs on HCC cell proliferation, and the proteomic analysis in HCC cell lines treated by regorafenib or lenvatinib.The present project for the first time performed a direct comparison of their pharmacological interventions for influencing whole cell proteomics using tandem mass tag-based peptide-labeling technique.
Project description:To investigate the specific roles of SIRT1 in the development of hepatocellular carcinoma, we employed large-scale gene expression analysis to identify the molecular signature that may affect enabling characteristics of cancer cells. Differentially expressed genes were analyzed on the SNU-182 cells transfected with SIRT1 siRNA and recapitulated molecular signatures that related to hallmarks of cancer. SIRT1 expression in hepatocellular carcinoma was analyzed by RT-PCR and western blot. RNA interference-mediated protein knockdown method was used to investigate oncogenic potential of SIRT1 in hepatocelluar carcinoma
Project description:Transforming Growth Factor beta (TGF-beta) is a pleiotropic cytokine playing a key role in liver carcinogenesis. The goal of this study was to identify genes differentially expressed in hepatocellular carcinoma cell lines PRC/PRF/5 and SNU-449 after a treatment with TGF-beta and/or Galunisertib, an inhibitor of the type I TGF-beta receptor (TGFBRI). Thus, cells were treated for 16 hours with 1 ng/mL recombinant human TGF-β1 (R&D Systems, Minneapolis, MN) and/or 10 μM LY2157299 (Sigma-Aldrich, St. Louis, MO) after overnight serum starvation. Gene expression profiling was performed using Agilent SurePrint G3 Human GE 8x60K microarrays.

Project description:We present an approach, named Drug Ranking Using ML (DRUML), which uses omics data to produce ordered lists of > 400 drugs based on their effectiveness in decreasing cancer cell proliferation. We trained and validated DRUML using in-house proteomics and phosphoproteomics data from a panel of 26 AML, 10 esophageal and 12 hepatocellular carcinoma cell lines in triplicate (three independent cultures per cell line) by LC-MS/MS
Project description:Hepatocellular carcinoma (HCC) is a highly prevalent and deadly disease world-wide. The survival of HCC patients is usually very poor due to the lack of efficient anti-cancer drugs acting against HCC cells. Structural modification is one of the important routes in chemical field for finding novel drugs with more potential bioactivities and broad bioactive spectra. Hence, a dehydroabietylamine derivative (DAAD-2) is prepared and subjected for cytotoxic activities on HCC cell lines.
