Hormonal Regulation of Actin and Tubulin in an Epithelial Cell Line From Chironomus tentans

摘要

The morphogenetic changes in an epithelial cell line from Chironomus tentans that are evoked by molting hormones and molting hormone agonists are accompaniend by transient changes in the concentration of actin and #beta#-tubulin protein and mRNA. As copmpared to controls, actin protein and mRNA concentrations increase by about 50%, whereas tubulin reaches maxima of 100% increase. The proportion between globular and filamentous actin remains constant after hormone treatment.
