Abstract 

Defects in differentiation are frequently observed in cancer cells. By appropriate treatment specific tumor cell types can be induced to terminally differentiate. Metastatic HO-1 human melanoma cells treated with IFN-β plus mezerein (MEZ) undergo irreversible growth arrest and terminal differentiation followed by apoptosis. In order to define the molecular changes associated with this process, changes in gene expression were analyzed by cDNA microarray hybridization and by semi-quantitative and quantitative RT-PCRs of representative 44 genes. The expression of 210 genes was changed more than two-fold at either 8 or 24 h post-treatment (166 up and 44 down). Major biological processes associated with the up-regulated genes were response to endogenous/exogenous stimuli (38%), cell proliferation (13%), cell death (16%) and development (30%). Approximately 34% of the down-regulated genes were associated with cell cycle, 9% in DNA replication and 11% in chromosome organization, respectively. Suppression of cell cycle associated genes appeared to directly correlate with growth arrest observed in the terminal differentiation process. Expression of Calpain 3 (CAPN3) variant 6 was suppressed by the combined treatment and maintained high in various melanoma cell lines. However, over-expression of the CAPN3 did not significantly affect growth kinetics and cell viability, suggesting that up-regulation of CAPN3 alone may not be a causative, but an associated change with melanoma development. This analysis provides further insights into the spectrum of up-regulated and the first detailed investigation of down-regulated gene changes associated with and potentially causative of induction of loss of proliferative capacity and terminal differentiation in human melanoma cells.
