 This study explored the role of type 11 collagen, COL11A1, in lung cancer by analysing its expression level, biological function, and impact on cell viability, apoptosis, cell cycle, migration, and signalling pathways in lung cancer cells. The results suggest that COL11A1 may contribute to the malignancy and pathogenesis of lung cancer. This article was authored by Hongbin 2, Jing Li, Lei Lin, and others.
