Project description:Wilm’s tumor(WT) is the most common malignant renal tumor in children, representing approximately 6-14% of all childhood cancers and about 95% of all pediatric renal malignancies. SKI-5C is a newly developed Sphk1 inhibitor. This small molecular inhibitor was firstly reported at 2009 by Wang et al. This study investigated the antitumor activity of SKI-5C in SK-NEP-1 cells. SKI-5C inhibited cell proliferation of SK-NEP-1 cells in a dose-dependent manner. Annexin V, Tunel and Hochest 33342 staining analysis showed that SKI-5C-treated cells showed more apoptotic features compared with the control.
Project description:Wilms tumor (WT) is an embryonic kidney cancer, for which histone acetylation might be a therapeutic target. LBH589, a novel targeted agent, suppresses histone deacetylases in many tumors. This study investigated the antitumor activity of LBH589 in SK-NEP-1 cells. LBH589 inhibited cell proliferation of SK-NEP-1 cells in a dose-dependent manner. Annexin V, Tunel and Hochest 33342 staining analysis showed that LBH589-treated cells showed more apoptotic features compared with the control. LBH589 treatment inhibited the growth of SK-NEP-1 xenograft tumors in nude mice. Arraystar Human LncRNA Array analysis of genes and lncRNas regulated by LBH589 identified 6653 mRNAs and 8135 lncRNAs in LBH589-treated SK-NEP-1 cells. The most enriched gene ontology terms were those involved in nucleosome assembly. KEGG pathway analysis identified cell cycle proteins, including CCNA2, CCNB2, CCND1, CCND2, CDK4, CDKN1B and HDAC2, etc. Ingenuity Pathway Analysis identified important upstream molecules: HIST2H3C, HIST1H4A, HIST1A, HIST1C, HIST1D, Histone H1, Histone H3, RPRM, HSP70 and MYC.
Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
