Abstract 한글 요약
Immune escape and ferroptosis resistance contribute to non-small cell lung cancer (NSCLC) carcinogenesis. This study aimed to investigate the role of N-methyladenosine (mA) reader heterogeneous nuclear ribonucleoprotein A2B1 (HNRNPA2B1) in NSCLC immune escape and ferroptosis resistance. HNRNPA2B1 expression was clinically elevated both in the NSCLC samples and single-cell transcriptome sequencing (scRNA-Seq). In vitro co-culture with activated CD8 T cells, HNRNPA2B1 high-expression hampered the CD8 T cell-mediated killing effect and accelerated the immune escape. Besides, the enforced HNRNPA2B1 high-expression alleviated the ferroptosis. Furthermore, HNRNPA2B1 targeted the LDHA mRNA mA modified site to enhance LDHA mRNA stability and lactate accumulation, thereby assisted NSCLC cells to evade CD8 T antitumor immunity and reduced IFN-γ secretion by CD8 T. Furthermore, IFN-γ could stimulate ferroptosis of NSCLC cells. Taken together, these findings revealed an important role for HNRNPA2B1 on NSCLC immune escape and ferroptosis resistance, which provided novel insight into mA modification in NSCLC.
