Immunoblot analyses of the ±DDR/−COL1 tumours revealed that neither DDR1b nor DDR2 expression altered the levels of either YAP1 and its phosphorylated forms (Supplementary Fig. 8A,B), MST1 and MST2 (Supplementary Fig. 8C,D), LATS1 (Supplementary Fig. 8E,F) or KIBRA (Supplementary Fig. 8G,H), when compared to tumours with repressed DDRs (+DOX). Here, YAP1 is linked to neoplasm.
