PKD1 and cancer: Using Cancer Cell Line Encyclopedia (CCLE) gene expression data63, we found that the expression of genes such as PKD1, a marker of poor metastasis-free survival64 (Fig. 6d) and MVP, which is linked to chemoresistance (effect size > 2, t-test P-value <0.05)65 was enriched in TNBC lines with extended S-phases (as compared to all other TNBC lines).
