Apoptosis-related gene and protein expression analysis under the different oxygen concentrations. (a) Expression levels of apoptosis-related genes were analyzed using RT-PCR. (b) Representative immunoblots and statistical analysis of protein levels in the experimental groups. Data are presented as the . , , and versus p5; ^#, ^##, and ^### versus p15; ^†, ^††, and ^††† versus C-NP cells at the same passage number.
