ACSS2 and neoplasm: To investigate the expression of FasL in clinical patients and the relationship between ACSS2 and FasL expression, our mIHC assay of tissues from 105 patients with paired PNETs showed that the expression of FasL in tumor tissues was higher than that in adjacent normal tissues (Figure 7A,B), and there was a strong positive correlation with the expression of ACSS2 (Figure 7C).
