US/Russia Collaborate to Make Proteins To Fight Intestinal Cancer
Russian scientist Anna Prokhorchuck working with UK and US scientists has found that mice lacking a protein called Kaiso show resistance to intestinal cancer. Kaiso, which this study showed is upregulated in intestinal tumors in mice and is expressed in human colon cancers, seems to play “an essential role in mammalian synapse-specific transcription.” they say in a study published this month in Molecular and Cellular Biology.
Mice bred to lack the Kaiso protein were healthy and fertile, with no detectable abnormalities of development or gene expression. “However, when crossed with mice bred to develop intestinal tumors, Kaiso-null mice showed a delayed onset of intestinal tumorigenesis,” the researchers say. “Our data suggest that Kaiso plays a role in intestinal cancer and may therefore represent a potential target for therapeutic intervention.”
