    Figure Lengend Snippet: CASP8 promotes NLRP12/NLRP3/NLRC4 and CASP1 activation upon HIF-1α signaling. a-b The protein and mRNA levels of NLRP12/NLRP3/NLRC4 and CASP1 was detected in retinas from WT mice with or without CASP8 knockdown (20 μΜ) that were harvested at the seventh day after reperfusion ( n = 6). The protein and mRNA levels were normalized to β-actin levels. c-d CASP8 elimination diminished the activation of NLRP12/NLRP3/NLRC4 and CASP1 in BV2 microglia exposed to OGDR ( n = 6). The protein and mRNA levels were normalized to β-actin levels. e-h Immunoblot and qRT-PCR analyses of targeting NLRP12/NLRP3/NLRC4 and CASP1 in vivo and in vitro (n = 6) with or without HIF-1α knockdown. The protein and mRNA levels were normalized to β-actin levels. i-j Protein and mRNA levels of HIF-1α upon NLRP12/NLRP3/NLRC4 suppression in vitro ( n = 6). The mRNA and protein levels were normalized to β-actin levels. k-l Knockdown of CASP1 suppressed the production of HIF-1α protein and mRNA in vitro ( n = 6). The data shown are representative of at least three independent experiments. The data are represented as the mean ± SD. * P < 0.05, ** P < 0.01, one-way ANOVA

    Activation of the CASP8-HIF-1α pathway elicits pyroptosis and promotes IL-1β production which in turn magnifies inflammatory cascades via the CASP8-HIF-1α-NLR axis. a The protein levels of cleaved GSDMD were detected in retinas from WT mice with or without CASP8 knockdown (20 μΜ) that were harvested at the seventh day after reperfusion ( n = 6). The protein levels were normalized to β-actin levels. b Western blot analysis of cleaved CASP1 and GSDMD in extracts from WT BV2 microglia and CASP8-specific KO cell line after OGDR injury ( n = 6). The protein levels were normalized to β-actin levels. c-d Cytotoxicity c and IL-1β production d in BV2 microglia under OGDR injury ( n = 6). e-f The protein levels of cleaved GSDMD were detected in vivo and in vitro with or without HIF-1α knockdown. The protein levels were normalized to β-actin levels. g-h Cytotoxicity g and IL-1β processing h were measured in the presence or absence of HIF-1α siRNA treatment in BV2 microglia ( n = 6, both). i Western blotting detection of the indicated proteins in BV2 microglia subjected to OGDR and OGDR concomitant with IL-1β neutralizing antibody treatment ( n = 6). The protein levels were normalized to β-actin levels. j CASP8 activity ( n = 6). The data shown are representative of at least three independent experiments. Data are represented as the mean ± SD. * P < 0.05, ** P < 0.01, experiments were assessed by one-way ANOVA, two-way ANOVA or two-tailed unpaired t-test
