EZH2 inhibition reshapes 3D chromatin architecture to induce immunogenic phenotype in small cell lung cancer [RNA-Seq]
Listed in NCBI GEO
EZH2, the enzymatic core of the Polycomb Repressive Complex 2 (PRC2), is overexpressed in small cell lung cancer (SCLC).
Description
Previous studies have shown that EZH2 enforces epigenetic silencing of immune and DNA repair genes, including Class I MHC molecules (HLA‑A/B/C) and SLFN11. To investigate how EZH1/2 inhibition reshapes the 3D chromatin landscape and its relationship to transcriptional regulation, we performed multi‑omic profiling of a neuroendocrine SCLC cell line (NCI‑H146) treated with the dual EZH1/2 inhibitor valemetostat for 9 days.
We employed Micro‑C sequencing for high‑resolution 3D genome mapping, ATAC‑sequencing for chromatin accessibility profiling, and RNA‑sequencing for whole‑transcriptome analysis. This is the RNA‑sequencing dataset.
