Fibronectin-1 (Fn1) and Il23 genes were increased in TAMs and BMDMs from 4T1 mice treated with calcitriol and from the 5000 IU group (Fig. 4A and B), but this observation was confirmed in BMDMs only for the group of mice fed a VD3 deficiency diet and treated with calcitriol (100 IU + cal) (Fig. 4C). Here, FN1 is linked to hyperinsulinemic hypoglycemia, familial, 4.
