Project description:Although mutations in p53 are infrequent in human melanoma, its function is abnormal. In this study, whole genome bead arrays were used to examine the expression of p53 target genes in extracts from 6 melanoma cell lines, compared to extracts derived from diploid human melanocytes and fibroblasts, to provide a global assessment of aberrant p53 function. The expression of these genes was also examined in extracts derived from melanocytes and melanoma cell lines in which p53 expression had been inhibited using shRNA and compared to cells that had been transduced with a control shRNA. Total RNA extracted from 18 samples was analysed representing duplicates of 6 melanoma cell lines, 1 melanocyte cell line and 2 fibroblast cell lines. Melanoma cell lines were compared to normal cell lines. In addition, IgR3, Mel-RM and melanocyte cell lines were transduced with either control shRNA or p53 shRNA to evaluate the effect of p53 on its target genes. Cell lines transduced with control shRNA were compared to cell lines transduced with p53shRNA. Duplicates were analysed.

Project description:Although mutations in p53 are infrequent in human melanoma, its function is abnormal. In this study, whole genome bead arrays were used to examine the expression of p53 target genes in extracts from 82 metastatic melanoma samples, compared to extracts derived from diploid human melanocytes, to provide a global assessment of aberrant p53 function.

Project description:Maternally Expressed Gene 3 (MEG3) encodes a lncRNA which is suggested to function as a tumor suppressor. MEG3 functions as a tumor suppressor in hepatoma cells, whose action is mediated by interaction with p53 protein to activate p53-mediated transcriptional activity and influence the expression of partial p53 target genes. Total RNA was isolated from hepatoma cells (HepG2 and SK-Hep-1) transfected with either control or MEG3 overexpression/knockdown constructs for global expression analysis.
