Inhibition of AIF-1 alleviates laser-induced macular neovascularization by inhibiting endothelial cell proliferation via restrained p44/42 MAPK signaling pathway
This study aimed to understand how AIF-1 effects the proliferation of CECs and the subsequent progression of MNV. To study this, a mouse MNV model was established through laser injury, and the AIF-1 expression levels were then measured using western blot and immunohistochemistry. AIF-1 siRNA was intravitreally injected to silence AIF-1 gene expression. Western blot and choroidal flat mount were performed to measure the progression of MNV and proliferation of the CECs. These results showed that the protein expression of AIF-1 was significantly elevated in the laser-induced mouse MNV model, and the expression trend was consi...

Kojic acid inhibits senescence of human corneal endothelial cells via NF- κB and p21 signaling pathways.
In this study, we investigated the anti-senescence effect of kojic acid on HCEC. Cell viability, migration ability and senescence were evaluated by MTT assay, migration assay, and senescence-associated beta-galactosidase (SA-β-Gal) staining, respectively. Senescence-related protein expression was analyzed by western blotting and immunofluorescence assay. Angiogenesis of human umbilical vein endothelial cells (HUVEC) was examined by tube formation assay and spheroid sprouting assay. The results showed that kojic acid could inhibit HCEC senescence, characterized by enhancing migration, decreasing the levels of SA-β-Gal sta...
