... The vector, which carries the gene into your cells, is considered harmless in humans. However, it is possible that the virus could grow and/or make the cells cancerous. There is a risk that the vector may enter the normal tissue surrounding the tumor, or other sites in the body. Another risk is that ...

Polycomb Group Proteins and Cancer

The Polycomb-group proteins (PcGs) are a family of proteins that use epigenetic mechanisms to maintain or repress expression of their target genes. They were originally discovered in Drosophila (fruit flies), though they've been shown to be conserved in many species due to their vital roles in embryonic development. These proteins' ability to alter gene expression has made them targets of investigation for research groups seeking to understand disease pathology and oncology.
