Fig 1. Expression of N-cadherin in the UROtsa parent and the As⁺³-and Cd⁺²-transformed cell lines.

(A and B). Real time-RT-PCR analysis of N-cadherin expression. The data is expressed as the number of transcripts of N-cadherin per 1000 transcripts of β-actin and is plotted as the mean ± SEM of triplicate determinations. (C and D). Western analysis of N-cadherin protein. * denotes significant difference from UROtsa parent cells (p<0.05).
