The human pancreatic cancer cell line Panc-1, which has previously been genotyped as homozygous for the NQO1*2 polymorphism [17] and characterized as NQO1 null, did not demonstrate detectable immunofluorescent staining for NQO1 either in the cytosol or mitotic spindles. The gene discussed is NQO1; the disease is familial pancreatic carcinoma.
