Figure Lengend Snippet: Graphic abstract of molecular mechanisms of MED1 promoting tumor progression in OSCC. A For untreated metastatic OSCC cells, MED1 facilitates MMP9 expression by promoting the transcription of MMP9, resulting in heightened migration and invasion of metastatic OSCC cells, just like strengthen the destructive force of "bandits". Additionally, MED1 upregulates PD-L1 expression via activation of the Notch signaling pathway, resulting in diminished cytotoxicity of CD8 + T cells within the tumor microenvironment and consequent attenuation of anti-tumor immunity responses. This behavior is similar to weaken the fighting capacity of "police". B For MED1 knockdown metastatic OSCC cells, the transcription of MMP9 is inhibited, leading to decreased migration and invasion of metastatic OSCC cells, just like weaken the destructive force of "bandits". This inhibition also leads to a decrease in PD-L1 expression through the suppression of Notch signaling pathway, indirectly enhancing the cytotoxic activity of CD8 + T cells in the TME and strengthening antitumor immunity responses. This behavior is similar to strengthen the fighting capacity of "police".

Figure Lengend Snippet: ( A ) Kaplan-Meier plot showing time to biochemical recurrence in months for NDUFS1 in the IHC cohort ( n = 60). p -values were estimated by log-rank test. Hazard ratio of 2.188 with a confidence interval of 1.056 to 4.530. Blue = low expression, orange = high expression. ( B ) Kaplan-Meier plot showing time to biochemical recurrence in months for ATP5O in the IHC cohort ( n = 61). p -values were estimated by log-rank test. Hazard ratio of 2.953 with a confidence interval of 1.364 to 6.391. Blue = low expression, orange = high expression.
