Article Title: | Growth hormone-induced alteration of morphology and tubulin expression in 3T3 preadipose cells |
Abstract: | Effects of growth hormone on morphology and cytoskeletal protein expression were examined in 3T3-F442A preadipocytes in serum-free medium. Between 2 and 5 days of culture 2 nM methionyl human growth hormone converted 3T3-F442A cells from a flat fibroblastic morphology to a rounded form with numerous membrane convolutions. Growth hormone treated cultures manifested a 30-40% reduction in cell volume. Growth hormone induced changes in morphology and volume preceded and were independent of lipogenesis. In cells treated with growth hormone, expression of α and β-tubulin as determined by Western blotting was found to increase approximately 50% within 72 h as compared to untreated cells. After 7 days, tubulin levels in growth hormone treated cells were approximately 40% of control levels. This indicated that morphological changes and alteration of tubulin expression were signatures of growth hormone action on 3T3-F442A cells. © 1989. |
