Does microinjected profilin affect cytoplasmic streaming in plant cells by rapidly depolymerizing actin microfilaments?
Profilin can act as a potent regulator of actin organization in living plant cells. Its rapid effect on the integrity of cytoplasmic strands and cytoplasmic streaming supports a model in which organelle movements depend upon microfilaments that exist in dynamic equilibrium with the pool of monomeric actin.
Our study showed that wogonin pre-treatment can protect RPE cells from H2O2-induced apoptosis. This suggests potential effect of wogonin in the prevention of retinal diseases associated with H2O2-induced oxidative stress such as AMD.
