Core Viewpoint - The study highlights the potential of NSD2 inhibitors as a therapeutic strategy for treating lung and pancreatic cancers, particularly in patients with KRAS mutations, and supports the clinical evaluation of combined therapies with KRAS inhibitors [4][9]. Group 1: NSD2 Inhibitors and Their Mechanism - NSD2 inhibitors (NSD2i) can reshape chromatin to treat lung and pancreatic cancers and work synergistically with KRAS G12C inhibitor Sotorasib [4]. - The research demonstrated that targeting NSD2 creates an epigenetic dependency, showing broad therapeutic efficacy in KRAS-driven preclinical cancer models [7]. - NSD2i effectively inhibits NSD2 activity at nanomolar concentrations (IC50) and shows high selectivity for related methyltransferases [7]. Group 2: Efficacy in Cancer Models - Continuous exposure to NSD2i can reverse pathological H3K36me2-driven chromatin plasticity, silencing oncogene expression and significantly reducing the survival rate of pancreatic and lung cancer cells [7]. - NSD2i has shown comparable effects in extending survival in advanced spontaneous KRAS G12C-driven pancreatic and lung cancer mouse models to those of Sotorasib [8]. - The combination of NSD2i and Sotorasib leads to significant tumor regression and even clearance, outperforming the effects of either treatment alone by several times [8]. Group 3: Implications for Treatment Strategies - Targeting the NSD2-H3K36me2 signaling axis presents an effective treatment strategy for refractory cancers, providing a theoretical basis for the clinical evaluation of combined NSD2 and KRAS inhibitors [9].
