Aims
Emerging resistance to Lenvatinib, which is used as a first-line agent for the treatment of advanced hepatocellular carcinoma (HCC), is still a concern. The aim of this study was to determine core factors of Lenvatinib resistance (LR) and their underlying molecular mechanisms.
Methods
CRISPR screening in HCC cells was conducted, which identified E3 ubiquitin ligase deltex 2 (DTX2) as a core LR-related gene. In vivo and in vitro models were used to clarify the function of DTX2 on LR and ferroptosis. The upstream regulators and downstream effectors of DTX2 were identified, revealing its complex regulatory network.
