Abstract
We isolated cDNA clones that represent genes whose expression is enhanced when resting Swiss mouse 3T3 cells are stimulated to proliferate with serum. Two clones (designated pME1 and pMR6) were analyzed further. A partial sequence analysis of the pME1 insert DNA indicated that it contained a 104-base-pair stretch with extensive homology to the 3' untranslated region of gamma actin. Similar analysis of the insert DNA from the pMR6 clone indicated that it did not correspond to any previously reported gene sequence. We used the pME1 clone as a probe to determine the level of gamma actin-specific transcript in 3T3 cells under a variety of conditions. The level of gamma actin-specific mRNA began to increase in resting cells upon serum stimulation and reached a peak at 6 h. Thereafter its level declined, and by 24 h it was hardly detectable. In contrast, pMR6-specific transcript was detectable in resting cells but remained elevated even at 24 h poststimulation. The level of gamma-actin mRNA was elevated in resting cells by 12-O-tetradecanoylphorbol-13-acetate, calcium ionophore A23187, and bombesin and to a lesser extent by cholera toxin, fibroblast-derived growth factor, and dibutyryl cyclic AMP. However, insulin, vasopressin, or epidermal growth factor failed to enhance gamma-actin mRNA levels in resting cells. Inhibitors of transcription diminished the induction of gamma-actin mRNA. Gamma-actin gene was superinduced in serum-stimulated cells by cycloheximide, an inhibitor of translation. Analysis of proteins from serum-stimulated cells by two-dimensional gel electrophoresis indicated that enhanced transcription of gamma-actin mRNA resulted in a concomitant increase in the corresponding actin protein. The possible role of gamma actin, a component of the cytoskeleton, in the regulation of cell growth is discussed.
