As in many other cell types, autoregulation of tubulin synthesis is evident in the intestinal epithelium of normal (vitamin D-replete) chicks: Suppression of protein (tubulin) synthesis by cycloheximide administration in vivo resulted within 30 min in a two-fold increase in RNA hybridizing with an alpha-tubulin probe. Vitamin D status revealed an additional regulatory component. alpha-Tubulin mRNA was elevated in vitamin D-deficient (-D) chicks and those treated with 1,25(OH)2D3 for 1-10 h prior to sacrifice, but declined precipitously 15-20 h after hormone, and in normal birds. These results suggested hormonally increased tubulin levels which in turn suppressed cellular alpha-tubulin mRNA. Analyses of total tubulin levels by [3H]-colchicine binding revealed low levels of the protein(s) in -D chicks, increased levels at 1-15 h after 1,25(OH)2D3, and maximum binding at 20 h after hormone and in normal birds.
