WebMar 28, 2024 · PARP Inhibitor Upregulates PD-L1 Expression and Enhances Cancer-Associated Immunosuppression. Clin Cancer Res. 2024 Jul 15;23(14):3711-3720. doi: 10.1158/1078-0432.CCR-16-3215. Epub 2024 Feb 6. WebThe data showed that P-STAT1 and PD-L1 expression was inhibited by the addition of inhibitor-treated cells. Similarly, the reduction of P-STAT1 and PD-L1 expression was more significant after the combined addition of Rh4 (50 μM) and HDAC2 inhibitor (Fig. 4 E). It appears that Rh4 inhibits PD-L1 by suppressing the HDAC2-JAK/STAT pathway.
