Is inhibition of protein kinase C sufficient to prevent or reverse effects of VEGF165 on claudin-1 and permeability in microvascular retinal endothelial cells?
In iBRECs, PKC isoforms are not crucially involved in the VEGF(165)-initiated signal transduction that affects permeability and expression of claudin-1. This finding is in contrast to published results concerning only short-term effects of VEGF(165). The results also confirmed that claudin-1 is a highly relevant component of functional tight junctions in retinal endothelial cells.
Using the 24-h blood pressure as a standard, home blood pressure was superior to office blood pressure in estimating blood pressure control in renal transplant patients. Nocturnal hypertension, however, was observed frequently, adding important clinical information about blood pressure control in this high-risk population.
