To investigate the relationship between KIFC1 and BUB1B in PC, we analysed transcriptomic data from The Cancer Genome Atlas (TCGA) Spearman's correlation analysis confirmed a strong positive correlation between the expression of KIFC1 and that of BUB1B in PC (r = 0.835; Figure 4B). Here, BUB1B is linked to pachyonychia congenita.
