Quantification of Zonula Occludens-1 mRNA expression in cultu-red bovine retinal endothelial cells, using SYBR green real-time PCR

A simple and rapid real-time reverse transcription-PCR (RT-PCR) technique using SYBR green fluorescence was developed to quantify Zonula Occludens-1 (ZO-1) mRNA expression in histamine-treated cultured bovine retinal microvessel endothelial cells. There was no dif-ference between the quantity of ZO-1 mRNA expression in histamine-treated (10-7M to 10-9 M) and untreated bovine retinal endothelial cells at high magnesium levels. Immunohisto-chemistry staining and western blot assay unequivocally demonstrated the approximately similar levels of ZO-1 protein in both histamine-treated and non-treated endothelial cells at high magnesium concentrations.
