Regulation of pancreatic gene expression by the secretory stimulants cholecystokinin-pancreozymin, caerulein and pilocarpine was studied in the rat, by using cloned cDNA probes to quantify concentrations of specific mRNAs (amylase, trypsinogen I and chymotrypsinogen B). It is concluded that long-term pancreatic stimulation results in pre-translational regulation of secretory-protein gene expression, with a preferential accumulation of RNA transcripts encoding serine proteinases, compared with that for amylase.

Gene expression in the rat dorsolateral prostate gland has been studied using cloned cDNA probes to the most abundant expressed mRNAs. One cDNA clone (pM-40) corresponds to two closely homologous mRNAs of about 880 nucleotides which code for two proteins of 23 and 21 kilodaltons (kDa). At least the 23-kDa protein contains a signal peptide. Another clone (pRWB) corresponds to a 1550-nucleotide mRNA which codes for a 52-kDa protein which also contains a signal peptide. The steady-state levels of these specific mRNAs increase in the dorsolateral prostate with sexual maturation. In castrated mature male rats, the M-40 mRNAs are inducible either by androgens or zinc, while the RWB mRNA is only responsive to androgens. In situ cDNA–mRNA hybridization histochemistry has been used to study the localization of the M-40 and RWB gene transcripts. Both M-40 and RWB mRNAs are most abundant in the epithelium of the lateral tip of the dorsolateral prostate. Following castration, the RWB mRNA decreases, while the M-40 mRNAs continue to be expressed in isolated areas of the epithelium. These castration-resistant cells maintain normal morphology in the absence of androgens.
