Project description:12-O-tetradecanoylphorbol-13-acetate (TPA) promotes skin carcinogenesis. CDDO is a potential antioxidative and antiinflammatory agent to prevent the TPA-induced skin cell transformation at nanomolar scale. We characterized the transcriptome, CpG methylome, and pathway network of JB6 cells treated with TPA and TPA + CDDO using RNA sequencing, methyl sequencing, and QIAGEN Ingenuity Pathway Analysis.

Project description:The two-stage cell transformation assay is an in vitro model cell culture system to identify the ability of chemicals to act as initiators or promoters of cell transforma- tion and also to study the cellular and molecular mechanisms of chemically induced morphological and neoplastic cell transformation. The global gene expression profiles of 3- methylcholanthrene (MCA)+12-O-tetradecanoylphorbol-13- acetate (TPA)-transformed C3H/10T1/2 cells are not known. Therefore, we have investigated the global transcriptional profile of MCA+TPA-transformed C3H10T1/2 cells using an 8×60 k probe microarray. The study revealed a differential regulation of pathways and gene expressions. Multifold dysregulation was seen in pathways of cancer, phagosomal activity, and tumor cell microenvironment information pro- cessing systems, notably the neuroactive ligand–receptor in- teraction, actin cytoskeleton regulation, tight junction, axon guidance, and cell adhesion molecules. The genes FGF1, EIF4E1B, MAGI1,and GRIA3 showed upregulation; these encoded the pluripotent fibroblast growth factor, the transla- tion initiation factor, the tight junction scaffolding protein, and the antiapoptotic as well as the enhancer of proliferation and migration, respectively. The genes CXCL7/CXCL5/CXCL12, H2DMB1,and HSPA1A showed downregulation; these encoded the chemotactic agent protein, the protein involved
