We studied the effect of incubation at 41 C on a clone of GC cells that had previously been stably transfected with a gene construct, pGHXGPT, containing -1800 to +8 of the rat growth hormone promoter fused to the structural gene for E. Coli xanthine guanine phosphor ibosyl-transferase. The effect of incubation of the clone containing pGHXGPT at 41 C was to enhance triiodothyronine induction of growth hormone secretion (2-fold, p<0.01) and of xanthine quanine phosphoribosyl-transferase activity (3-fold, p< 0.01). We conclude that the increase in triiodothyronine-induced growth hormone production during heat stress occurs by stimulation of the growth hormone promoter.
