FGFR3 and diabetes mellitus: FOXA1 expression was positively correlated to the four other diabetes-related genes, PAK4, FGFR3, MTA3, and KIF22, found in the HR+ breast cancer, but not to the genes highly expressed in TNBC such as TNFAIP3, IL1B, ANXA1, and CDC20. This suggests that FOXA1 has a positive correlation to other diabetes-related genes in HR+ breast cancer (Figure 3a,b).
