Evaluation of New Targeted Therapies in 3D Culture Models for Pancreatic CancerAvedikian, Saro; The University of Arizona College of Medicine - Phoenix; Han, Haiyong (The University of Arizona., 2021)Pancreatic Ductal Adenocarcinoma (PDAC) is a deadly cancer that displays a highly heterogeneous and complex tumor microenvironment. Novel therapeutic agents that target DNA regulatory networks known as super-enhancers (SEs) have recently gained attention in the potential treatment of PDAC. In order to accurately study the effects of super-enhancer inhibitors, cell culture models that accurately mimic the tumor microenvironment are necessary. In this experiment, two PDAC cell lines (B011 and B028) are grown under both 3D and 2D culture conditions and the growth inhibitory effects of three super-enhancer inhibitors (triptolide, THZ1, and THZ2) are determined. The 3D PDAC cell cultures of the B011 cell line demonstrate greater resistance to all three drugs tested from the class of super-enhancer inhibitors. Based on these findings, 3D PDAC culture models may provide more accurate means to study novel chemotherapy agents than traditional 2D culture methods. The implications of this are significant as it may pave the way for quick and affordable precision medicine modalities in the future for the treatment of PDAC.
