NEW YORK, May 11, 2021 /PRNewswire/ A research team has designed a molecule with potential to interfere in a new way with altered proteins that cause abnormal growth in 35 percent of pancreatic cancers.
Published online in
Nature Communications on May 11, a new study found that a molecule called a monobody clings to cancer-causing versions of the KRAS protein and keeps them from transmitting their signals. Changes in the DNA of the
KRAS gene – which encodes a molecular switch that toggles between active and inactive states to regulate growth – cause the related protein to become stuck in the on mode. Cells with such mutations continually multiply and give rise to cancer.

An antioxidant found in green tea may increase levels of p53, a natural anti-cancer protein, known as the âguardian of the genomeâ for its ability to repair DNA damage or destroy cancerous cells. Published today in Nature Communications, a study of the direct interaction between p53 and the green tea compound, epigallocatechin gallate (EGCG), points to a new target for cancer drug discovery.
âBoth p53 and EGCG molecules are extremely interesting. Mutations in p53 are found in over 50% of human cancer, while EGCG is the major anti-oxidant in green tea, a popular beverage worldwide,â said Chunyu Wang, corresponding author and a professor of biological sciences at Rensselaer Polytechnic Institute. âNow we find that there is a previously unknown, direct interaction between the two, which points to a new path for developing anti-cancer drugs. Our work helps to explain how EGCG is able to boost p53âs anti-cancer activity, opening the door to dev
