STAT3 and HIF-1α cooperatively enhance PD-L1 expression in EML4-ALK-translocated pADC cells under hypoxia. Taken together, these findings suggest that EML4-ALK might increase HIF-1α expression under hypoxia by enhancing transcription and inhibiting ubiquitination of HIF-1α, resulting in the stabilization of HIF-1α, consequently contributing to HIF-1α-mediated upregulation of PD-L1 under hypoxia. |
