Figure 8. Upregulation of lncRNA GAS5 alleviated DN in vivo. (A) H&E staining of DN results. The LV-GAS5 group was injected with LV-GAS5, and the LV-NC group was injected with LV-NC (LV-GAS5 group=8, LV-NC group=8); (B) The expression level of lncRNA GAS5 was measured by qPCR in both groups; (C) Urinary albumin excretion rate was decreased in the LV-GAS5 group compared with that in the LV-NC group; (D–F) The expression level of FN (D), Col-4 (E), and TGFβ1 (F) were measured by qPCR in the DN rat model transfected with LV-GAS5 or LV-NC; (G–H) The expression level of FN, Col-4, and TGFβ1 were measured by western blot in the DN rat model transfected with LV-GAS5 or LV-NC; (I) qPCR results revealed that the expression level of miR-221 decreased in the DN rat model transfected with LV-GAS5; (J–L) The expression level of SIRT1 was upregulated in the DN rat model transfected with LV-GAS5; (M–O) The expression level of p53 was upregulated in DN transfected with LV-GAS5; (P) qPCR results revealed that there is positively correlation between lncRNA GAS5 and SIRT1 (
