SMYD3 Impedes Small Cell Lung Cancer Sensitivity to Alkylation Damage Through RNF113A Methylation-Phosphorylation Cross-talk

Abstract

Significance: SCLC rapidly becomes resistant to conventional chemotherapy, leaving patients with no alternative treatment options. Our data demonstrate that SMYD3 upregulation and RNF113A methylation in SCLC are key mechanisms that control the alkylation damage response. Notably, SMYD3 inhibition sensitizes cells to alkylating agents and promotes sustained SCLC response to chemotherapy. This article is highlighted in the In This Issue feature, p. 2007.
