Small, Persistent Increase in the Expression of NOD1 May Promote Cancer Risk

ISB researchers have found that a small, persistent increase in the expression of NOD1 could be responsible for higher cancer risks. The research team found that a slight 1.5-fold uptick in NOD1 expression can activate the protein and downstream signaling pathways in a manner similar to vast (30- to 200-fold) overexpression.

While scientists have long studied bacterial infections, less attention has been paid to how the host immune response affects bacterial gene expression in the body. In a just-published paper in PNAS, ISB researchers detailed how the bacterium Salmonella conceals itself from the host immune system.
