1 Stimulation of cultured bovine chromaffin cells with histamine (10(-5) M), nicotine (10(-6) M), and veratridine (2 x 10(-6) M) results in a time-dependent up to 5-fold increase in proenkephalin (Penk) mRNA levels. Nicotine proenkephalin Bos taurus
2 Stimulation of cultured bovine chromaffin cells with histamine (10(-5) M), nicotine (10(-6) M), and veratridine (2 x 10(-6) M) results in a time-dependent up to 5-fold increase in proenkephalin (Penk) mRNA levels. Nicotine proenkephalin Bos taurus
3 Similarly, incubation of chromaffin cells with cycloheximide (10(-6) M), given at 0-6 h, blocks the increase in Penk mRNA after stimulation with histamine and nicotine indicating that ongoing protein synthesis is necessary for the delayed rise of Penk mRNA. Nicotine proenkephalin Bos taurus
