Ubiquitination degradation of GATA4 by CUL4B promotes ovarian cancer metastasis by inducing lysosomal acidification

Xin Yin & Junlin He et al. · 2026-02-09

TL;DR

It is demonstrated that GATA4 suppresses lysosomal acidification and epithelial–mesenchymal transition, while its CRL4B-mediated ubiquitination and degradation in metastatic ovarian cancer cells leads to reduced H3K27ac modification at tumor suppressing genes.
