These findings, however, seem to be conceivable because of the short duration of the study (3 months) not allowing gross renal fibrosis develop; it should, additionally, be underlined that the indices of renal fibrosis, i.e., TGF-β, collagen type IV, and fibronectin were detected to be decreased at gene expression levels. The gene discussed is FN1; the disease is renal fibrosis.
