| heal.abstract | We have tested the hypothesis that differentiation and growth arrest of Y-79 human retinoblastoma cells in culture is associated with a modification of gene expression. We first examined proteins translated from mRNAs isolated from Y-79 cells growing in suspension and in attachment cultures in serum-containing medium and found them to be markedly different. This suggests that membrane-substrate interactions are of major consequence in the biochemical differentiation of these cells. Secondly, we examined the patterns of proteins translated from attached cells which had been induced to morphologically differentiate into neuronal-like and glial-like cells by serum-withdrawal and dibutyryl cAMP treatment respectively. The in vitro translatable proteins of mRNAs isolated from these cultures were found to be markedly different from those of the suspension and attachment cultures. Thirdly, we found that treatment of cells growing in attachment culture in serum-containing medium supplemented with 8-bromo cAMP, butyrate and retinoic acid as well as dibutyryl cAMP resulted in discreet alterations in proteins translated in vitro from extracted mRNAs. Although all these substances inhibit the growth of Y-79 cells, only dibutyryl cAMP and butyrate result in morphological differentiation of cells. Our results suggest that (1) attachment and morphological differentiation of Y-79 cells are both related to specific alterations in gene expression and (2) differentiation and inhibition of cell growth by various agents can be correlated with changes in translatable mRNA species although all agents do not act in the same mode. | en |
