Interestingly, breast cancer subtype analyses using TCGA RNA sequencing data available on The University of Alabama at Birmingham CANcer data analysis portal (UALCAN) [72,73] platform showed that the expression levels of KIFC1 (Figure 2I), AURKB (Figure 2J), BIRC5 (Figure 2K), and CDCA8 (Figure 2L) were the highest in TNBCs, suggesting their high importance in driving the biology of breast tumors with TN status. The gene discussed is CDCA8; the disease is breast cancer.
