CDC5L and familial pancreatic carcinoma: Then, the KIF4A and CDC5L gene and protein expression were shown in the related website (https://www.proteinatlas.org/ENSG00000090889-KIF4A or ENSG0000096401-CDC5L/pathology), and we could find the results in the following: the expression level of KIF4A protein in peripheral blood of pancreatic cancer has guiding significance for prognosis (P < 0.05, Supplementary Figure S1), and there are more KIF4A and CDC5L proteins in tumor (Supplementary Figure S1 and S2).
