From: THZ1 targeting CDK7 suppresses c-KIT transcriptional activity in gastrointestinal stromal tumours
CDK7 inhibition leads to the suppression of c-KIT transcriptional activity and protein expression in GIST cells. A, B qRT–PCR and immunoblotting analysis of c-KIT expression after siRNA-mediated CDK7 knockdown in GIST-T1 and GIST-882 cells. C, D qRT–PCR and immunofluorescence assays showed that c-KIT expression changed after THZ1 treatment in GIST-T1 and GIST-882 cells. E Immunoblotting analysis showed that the expression of c-KIT and downstream ERK and AKT signalling pathway components was inhibited following THZ1 treatment at the indicated concentration in GIST-T1 and GIST-882 cells for 24 h. F Immunoblotting analysis indicated that combination treatment with imatinib and THZ1 enhanced c-KIT expression inhibition in GIST-T1 and GIST-882 cells for 24 h
