Figure 3: A) Representative agarose gel photographs showing ethidium bromide stained RT-PCR products in Normal cells exposed with normal serum (NC+NS) and patient cells exposed with normal serum (PC+NS). B) The signal intensities of these RT-PCR products were measured using SCION IMAGE analysis software. The relative levels of target mRNA expression were determined by normalizing their individual band intensity to β actin band intensity. The mRNA expression of each gene in PC+NS is plotted as percentage of that in NC+NS. Each bar represents mean SD for the combined results of six separate experiments from different individuals in triplicate. (Statistical significance is shown by **= p<0.05).
