Figure Lengend Snippet: Mechanisms of PD-L1 regulation in lung cancer. PD-L1 expression in tumor cells is regulated at multiple levels. The p53–p21 axis can negatively influence PD-L1 transcription, while oncogenic pathways such as PI3K/AKT and JAK/STAT promote its up-regulation. Epigenetic mechanisms play a critical role: histone acetylation and methylation dynamically regulate chromatin accessibility, and DNA methylation (e.g., via DNMT1) can repress or activate PD-L1 transcription depending on context. Collectively, these mechanisms contribute to PD-L1-mediated immune evasion and tumor survival.
