CHR8 (chr8 accessibility complex subunit 1) is a component of the chr8 remodeling complex that regulates chr8 accessibility and gene expression. The protein functions as an accessory subunit that facilitates chr8 reorganization through interactions with chr8 remodeling machinery 1. While CHR8's canonical role involves nucleosome assembly and DNA replication processes, recent evidence reveals critical roles in cancer progression. In lung cancer, CHR8 overexpression promotes cell proliferation and migration by binding to the transcription coactivator YAP and enhancing downstream Hippo pathway oncogenes 2. Similarly, in breast and cervical cancers, CHR8 facilitates oncogenic YAP transcription to drive tumorigenesis 3. CHR8 amplification has been identified as a driver gene in high-grade serous ovarian cancer 1 and represents one of seven prognostic genes associated with ovarian cancer progression and poor survival outcomes 4. Beyond cancer, CHR8 overexpression exacerbates doxorubicin-induced cardiotoxicity through the IRF9/GSDMD/CASP-1 pyroptotic pathway 5. Elevated CHR8 expression correlates with type 2 diabetes 6. These findings establish CHR8 as a multifunctional regulator with significant clinical relevance as a potential therapeutic target across multiple disease contexts.
