Figure 3. Expression profile of all UPR related genes from the PCR array. The scatter plot shows expression levels of UPR related genes tested in FECD samples compared to normal controls. Of 84 UPR related genes, 42 (51%) were altered. The red circles represent the genes that had at least a twofold increase in expression, and the green circles are those that had a twofold decrease in expression compared to the control.
