Rhodamine diabetic retinopathy BRB rat

Y Zhang, G Xu, Q Ling, C Da
This study examined aquaporin 4 (AQP4) and Kir4.1 (a potassium channel subunit) in normal and diabetic adult Sprague-Dawley rats, and determined the effect of minocycline treatment. Retinal expression of the AQP4 and Kir4.1 genes was examined using double immuno fluorescence, Western blot analysis, and real-time reverse transcription-polymerase chain reaction. Retinal levels of vascular endothelial growth factor (VEGF), ionized calcium-binding adaptor molecule (Iba)-1 and interleukin (IL)-1β were also ascertained...

Blood-retinal barrier (BRB) breakdown is a hallmark of diabetic retinopathy, but the molecular changes that cause this pathology are unclear. Occludin is a transmembrane component of interendothelial tight junctions that may regulate permeability at the BRB. In this study, we examined the effects of vascular endothelial growth factor (VEGF) and diabetes on vascular occludin content and barrier function. Sprague-Dawley rats were made diabetic by intravenous streptozotocin injection, and age-matched animals served as controls...
