Bcl-2 gene silencing in pediatric epithelial liver tumors.

BACKGROUND Proteins of the Bcl-2 family prevent cells of various tumor types from undergoing apoptosis and thus contribute to their chemotherapy resistance. The phenotype of multidrug resistance is a major factor for poor treatment results of advanced epithelial liver tumors in children. The role of Bcl-2 proteins in these tumors is yet unclear. The purpose… CONTINUE READING
