KIF11 and pancreatic adenocarcinoma: Apart from this experimental evidence, Liu et al. have further shown by IHC that KIF11 was overexpressed in PAC clinical specimens (n = 95) compared to normal pancreatic tissue samples (n = 10), tissues adjacent to pancreatic adenocarcinomas (n = 10), and benign pancreatic cystadenomas (n = 12) [15].
