HNF4A impairs angiogenesis in PDR by regulating the CACNA1A/VEGFA axis in vitro. (A) Expression of HNF4A, CACNA1A, and VEGFA in HRMECs treated with sh-HNF4A, sh-VEGFA, and oe-CACNA1A either separately or in combination determined by qPCR. (B) Expression of HNF4A, CACNA1A, and VEGFA in HRMECs treated with sh-HNF4A, sh-VEGFA, and oe-CACNA1A either separately or in combination determined by Western blot. (C) Tube-forming ability of HRMECs treated with sh-HNF4A, sh-VEGFA, and oe-CACNA1A either separately or in combination. */#
P < 0.05, compared with HRMECs treated with sh-NC + oe-NC + sh-NC. The cell experiment was run in triplicate independently.
