Expression and survival analysis of PRGs in PDAC. A The protein expression score of staining and intensity of NLRP1 and CASP4 proteins in all PDAC samples (HPA database). Protein expression score is based on immunohistochemical data manually scored with regard to staining intensity (negative, weak, moderate or strong) and fraction of stained cells (< 25%, 25–75% or > 75%). B Immunohistochemical staining of NLRP1 and CASP4 proteins in PDAC. C Methylation levels of CASP4 at chr11:104838825–104841325 and chr11:104826922–104829422 in PDAC and para-cancer tissues. D The OS survival curves of NLRP1 and CASP4 mRNA expression level in PDAC. E CASP4 and NLRP1 immunohistochemistry for patients from Zhongnan Hospital (×200)
