In addition, we have analyzed different mRNAs of PTECs of the patients with T2DM compared with those of the normal individuals in our previous study (Tsai et al., 2018), and we also found that FBLN1 mRNA expression was elevated in PTECs of the patients with T2DM (fold change of 7.14 as compared with the normal individuals). Here, FBLN1 is linked to type 2 diabetes mellitus.
