Overexpression of hTERT and HPV16-E7 in imAPAD and imGPAD cell lines. (A) overexpression of hTERT and HPV16-E7 protein was confirmed by Western blotting in the paired imAPAD and imGPAD cell lines (passage 15–17) and compared with 1°APAD and 1°GPAD preadipocytes (passage 6) from the same donor. Labeling for actin is shown as a loading control. (B) Telomerase activity was determined in imAPAD and imGPAD cell lines (passage 11) and 1°APAD and 1°GPAD cells (passage 6) (n = 3, mean ± SEM; *P < 0.05, paired samples t-test). Heat treatment was used to inactivate telomerase as a negative control.
