Figure Lengend Snippet: Core Hippo kinase regulation of CSPG4 in TcdB exposed pericytes . A , pericytes were exposed to 1 ng/ml of TcdB2 for 24 h and colonic epithelial cells were exposed to 10 ng/ml of TcdB2 for 24 h. Multiple wells from each treatment were combined for RNA isolation. RT-qPCR was used to quantify CSPG4 transcripts. RT-qPCR data are presented as mean (n = 3) ± S.D. with each data point as a technical replicate. ∗ p < 0.05 determined by Student’s t test. B , Immunoblots from protein lysates acquired from pericytes exposed for 24 h to 1 ng/ml of TcdB. C , immunoblots from protein lysates obtained from pericytes or HeLa cells exposed for 24 h to 1 ng/ml of TcdB. Phosphorylated LATS1 (pLATS1) was detected with an antibody recognizing phosphorylation at Thr 1079. D , densitometry analysis of pLATS1 immunoblots. Relative band density is presented as mean (n = 2) ± S.D. with each data point as a technical replicate. ∗ p < 0.05 determined by Student’s t test. E , immunoblots from protein lysates acquired from pericyte or HeLa cells exposed for 24 h to 1 ng/ml of TcdB in the presence or absence of 10 μM XMU-MP-1. F , immunoblots from protein lysates taken from HeLa cells exposed for 24 h to 1 ng/ml of TcdB with and without of 30 μM TRULI.
