  • a The growth-inhibitory effects of AdCAPTEN infection were calculated as (x − y)/x (x, mean cell number 5 days after AdCA infection at 100 MOI; y, mean cell number 5 days after AdCAPTEN infection at 100 MOI).

  • b The correlations between transcription levels of Integrin αv and adenoviral transduction efficiencies or growth-inhibitory effects were both statistically significant (Integrin αv versus growth inhibition, P = 0.009, ρ = 0.924; Integrin αv versus transduction efficiency, P = 0.014, ρ = 0.869; Spearman’s rank correlation).

  • c Mean percentages of 5-bromo-4-chloro-3-indolyl-β-d-galactopyranoside-positive cells were measured microscopically 24 h after AdCALacZ infection at 100 MOI.

  • d The transcription levels of PTEN, PIK3CA, Integrin αv, Integrin β3, and Integrin β5 were examined using semiquantitative RT-PCR. The intensity of each band was calculated as a ratio against the intensity of the corresponding β2-microglobulin band by densitometric analysis.
