Processing of pro-CGRP in a rat medullary thyroid carcinoma cell line transfected with protease inhibitors.


A rat medullary thyroid carcinoma cell line, CA77, was used to study the effect of a series of biosynthesized protease inhibitors on the proteolytic cleavage of the endogenously synthesized pro-CGRP. This cell line efficiently converted the pro-CGRP to mature CGRP as assessed by chromatography of cell extracts followed by radioimmunoassay for CGRP. CA77… (More)
