CASP8 levels are elevated in prostate cancer tissues. (A) IHC for CASP8 on tissue microarrays (TMAs) containing benign/normal prostate tissues (n = 16), BPH (n = 16), and prostate cancers samples (n = 26). The staining intensity of CASP8 was scored as 0 (negative), 1 (low), to 2 (medium/high). Representative images are shown. Scale bars represent 20 microns. (B) The protein levels of CASP8 are higher in prostate cancer when compared to normal tissues and BPH. The distribution of CASP8 intensity scores of patient samples are shown.
