EpCAM is expressed in RB tumors.

<p>(A) EpCAM mRNA ranges from 2-100 fold in RB tumors (n = 30). Pooled non-neoplastic retinas (n = 3) was used as control. Data is expressed as fold change relative to control. (B) Immunoblot for protein levels of EpCAM siRNA knockdown in Y79 and WERI-Rb-1 cell lines.
