Quantitative real-time PCR was performed to analyze mRNA expression. shows the expression of from the eight age groups normalized to mRNA. demonstrates fold change in expression relative to the calibrator of the 20-year-old group. is the comparison of the average level of mRNA expressed in HCECs between the young (≤ 30 years) and old (≥ 50 years). Data are presented as mean±standard deviation, and a
