Vitreal growth factors activate their respective receptors of cells in the vitreous, trigger their downstream signaling transduction (e.g. phosphoinositide 3 kinases (PI3Ks)/Akt), and drive cellular responses intrinsic to the pathogenesis of PVR.
Our findings are crucial steps in determining the critical roles of the PI3K/Akt signaling pathway and miRNA-29b in pathogenesis of proliferative vitreoretinopathy (PVR) which may be a potential target for preventing or treating PVR.
