Expression of the cholecystokinin (CCK), gastrin and enkephalin A genes were studied by Northern blot analysis and a library of sequence-specific radioimmunoassays in human cell lines. The human small-cell lung carcinoma line (SCLC) U-1690 expressed moderate levels of CCK mRNA as compared to the human neuroepithelioma cell line SK-N-MC. Neither gastrin nor (pro)enkephalin A mRNAs were detectable in the U-1690 cell line. In contrast, the SCLC-line H-69 expressed Enk A but no CCK mRNA. The radioimmunoassays showed that the CCK mRNA transcript in the SCLC line U-1690 also is translated, and that preproCCK is processed into bioactive, carboxyamidated CCK peptides. Thus, the human small cell carcinoma cell line U-1690 is a useful model for studies of cell-specific CCK gene expression.
