To further explore the potential mechanism of PCMT1 in breast cancer, we used the LinkedOmics database to study the coexpression of PCMT1. The results showed that there was a significant positive correlation between PCMT1 and NUP43 (r = 0.6322, P = 4.75e − 123) (Figures 5(a) and 5(b)). The gene discussed is PCMT1; the disease is breast cancer.
