As indicated by qRT-PCR and western blot analyses of kidney biopsy tissue, expression of renal FN and Col IV, as well as STAT1 and TGFβ1 was significantly higher in renal tissue from patients with DN than in control tissue obtained from non-diabetic subjects (Figure 1), the whole western blots seen in the Supplementary Figure 1. Here, TGFB1 is linked to liver dysplastic nodule.
