Extended Data Fig. 3: nPD-L1 and p-Y705-Stat3 are required for hypoxia-induced GSDMC expression.

(a) Real-time quantitative polymerase chain reaction (RT–qPCR) analysis of mRNA levels of gasdermin family members in the indicated MDA-MB-231 stable transfectants. Data are shown as mean ± SD of n = 3 independent experiments. (b and c) GSDMC mRNA (b) and protein (c) levels in MDA-MB-231 cells under hypoxia. Data of (b) are shown as mean ± SD of n = 3 independent experiments. Blots are representative of three independent experiments. N, normoxia; H, hypoxia. (d) RT–qPCR analysis of mRNA levels of GSDMC in the indicated MDA-MB-231 stable transfectants. Data are shown as mean ± SD of n = 3 independent experiments. (e-g) MDA-MB-231 cells were cultured under hypoxia and treated with HO-3867 (20 μM) or ivermectin (25 μM). GSDMC mRNA (e) and protein (f) levels were analysed by RT–qPCR and immunoblotting, respectively. GSDMC promoter luciferase reporter plasmids were transfected to cells, and luciferase activity was measured in (g). Data of (e) and (g) are shown as mean ± SD of n = 3 independent experiments. Blots are representative of three independent experiments. P values of all statistical analysis were determined by two-sided Student’s t-test. Statistical source data and unprocessed blots are provided in Source Data Extended Data Fig. 3.
