KIFC1 and breast cancer: Analysis of RNA sequencing data in the UALCAN portal also showed that the expression levels of ATAD2 (Figure 3J), E2F1 (Figure 3K), and FOXM1 (Figure 3L) oncogenes were the highest in TNBCs among breast cancer subtypes, suggesting that the simultaneous overexpression of (i) ATAD2, E2F1, and FOXM1; (ii) centrosome amplification genes; and (iii) the centrosome clustering genes KIFC1, AURKB, BIRC5, and CDCA8 could play a key role in the tumor biology of TNBC.
