Messenger RNAs for calcitonin (CT) and calcitonin gene related peptide (CGRP) have been detected in a human medullary thyroid carcinoma cell line. DNA sequences of their cloned cDNAs, and genomic restriction mapping, indicate that both mRNAs probably originate from a single gene; the separate mRNAs are derived by alternative processing. The calcitonin gene is expressed in 10 of 10 examined culture lines of human lung cancer; most of these lines express a higher ratio of CGRP to CT specific mRNA than does the medullary thyroid carcinoma cell line.
