We observed that the levels of cadherin 1 RNA were 36-fold lower in RIP-Tag; RIP-tva tumor cells infected with RCASBP-Bcl-xL than in uninfected parental cells (data not shown), suggesting that Bcl-xL is likely to lower expression of cadherin 1 at the transcriptional level. This evidence concerns the gene CDH1 and neoplasm.
