Interestingly, DSS1 expression was markedly increased (55.6; median of DSS1 relative expression) in the group of breast cancer cases with low Ki67 labeling indices (< 20%) compared with the expression (36.0; median of DSS1 relative expression) in the group with high Ki67 labeling indices (≥ 20%). Here, MKI67 is linked to breast carcinoma.
