^aThe intensities of signals were quantified by densitometry. Positive control included in the array blot was used to normalize and compare the results from different membranes. Values obtained from the control K_CTRL/F_CTRL OTC were arbitrarily assigned a value of 1. Values represent the mean fold increase as compared with control OTC (n = 3).

^bmRNA expression levels of these genes were further verified by qPCR.

^cP < 0.01.

^dP < 0.1.
