Project description:Using a CRISPR-based autochthonous SCLC GEMM to study the consequences of KDM6A/UTX inactivation, we found that KDM6A inactivation induced plasticity from ASCL1 to NEUROD1 resulting in SCLC tumors with open chromatin at the NEUROD1 promoter that express both ASCL1 and NEUROD1. Mechanistically, KDM6A binds and maintains ASCL1 target genes in an active chromatin state with its loss increasing H3K27me3 near their promoters leading to a cell state that is primed for ASCL1 to NEUROD1 subtype switching. This work identifies KDM6A as an epigenetic regulator that controls ASCL1 to NEUROD1 subtype plasticity and provides a novel autochthonous SCLC GEMM to model ASCL1 and NEUROD1 subtype heterogeneity and plasticity, which is found in 35-40% of human SCLCs.

Mechanistically, KDM6A binds and maintains ASCL1 target genes in an active chromatin state with its loss decreasing H3K4me1 and increasing H3K27me3 at enhancers of neuroendocrine genes leading to a cell state that is primed for ASCL1 to NEUROD1 subtype switching. This work identifies KDM6A as an epigenetic regulator that controls ASCL1 to NEUROD1 subtype plasticity and provides a novel autochthonous SCLC GEMM to model ASCL1 and NEUROD1 subtype heterogeneity and plasticity, which is found in 35-40% of human SCLCs.

Project description:The UTX/KDM6A gene encodes the UTX histone H3K27 demethylase, which plays an important role in mammalian development and is frequently mutated in cancers and particularly, in urothelial cancers. Using BioID technique, we explored the interactome of different UTX isoforms.

Project description:Small cell lung cancer (SCLC) exists broadly in four molecular subtypes: ASCL1, NEUROD1,POU2F3, and Inflammatory. Initially SCLC subtypes were thought to be mutually exclusive, butrecent evidence shows intra-tumoral subtype heterogeneity and plasticity between subtypes.Using a CRISPR-based autochthonous SCLC GEMM to study the consequences of KDM6A/UTXinactivation, we found that KDM6A inactivation induced plasticity from ASCL1 to NEUROD1resulting in SCLC tumors with open chromatin at the NEUROD1 promoter that express bothASCL1 and NEUROD1. Mechanistically, KDM6A binds and maintains ASCL1 target genes in anactive chromatin state with its loss increasing H3K27me3 near their promoters leading to a cell state that is primed for ASCL1 to NEUROD1 subtype switching. This work identifies KDM6A as \an epigenetic regulator that controls ASCL1 to NEUROD1 subtype plasticity and provides a novel autochthonous SCLC GEMM to model ASCL1 and NEUROD1 subtype heterogeneity and plasticity, which is found in 35-40% of human SCLCs.
