The exogenous lactate accelerated the proliferation, oxaliplatin resistance and aerobic glycolysis in GC that inhibited by HNRNPC silencing. Moreover, HNRNPC silencing up-regulated the iron concentration accumulation and ferroptosis, and the exogenous lactate and ferrostatin-1 (Fer-1, ferroptosis specific inhibitor) co-administration reduced the iron concentration. Mechanistically, MCT1 was identified as the downstream target of HNRNPC, and HNRNPC targeted MCT1 to fortify the lactate accumulation, thereby accelerating the ferroptosis resistance in GC.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Overall, these findings revealed the novel role of ferroptosis-related HNRNPC on GC lactate accumulation and lactate-induced tumorigenesis in GC tumor microenvironment.
