Gene expression profiles of BxPC-3, MiaPaCa-2 and PANC-1 cell lines treated with DMSO and THZ1 respectively
By screening an epigenetic-related compound library, we identified THZ1, a covalent inhibitor of CDK7, as a promising candidate. Multiple long-established and patient-derived PDAC cell lines (PDC) were used to validate the efficacy of THZ1 in vitro. In addition, patient-derived xenograft (PDX) models and animal models of PDAC were utilized for examining THZ1 efficacy in vivo. Furthermore, RNA-Seq and H3K27Ac-based Super-Enhancers (SEs) analyses were performed to reveal the molecular mechanism of THZ1 treatment. Lastly, PDAC cell lines with primary or acquired resistance to THZ1 were investigated to explore the potential mechanism of THZ1 susceptibility. Overall design: Briefly, BxPC-3, MiaPaCa-2 and PANC-1 cell lines were treated with DMSO or THZ1(100nM) for 6hr were collected in biological triplicates.Each sample has 3 repeats. Each sample has 3 repeats.
