The article I chose to review discussed how protein, or more specifically the p53 protein, is used by the body to help prevent cancer. The p53 protein helps to prevent cancer in three different ways. This protein helps to stop cancer from developing by sensing stress and then turning on the genes that prevent cell division. P53 also combines with other molecules to trigger a process called apoptosis in over stressed cells. Apoptosis is a type of cellular suicide. New studies have found that p53 also helps to slice RNA into smaller regulatory molecules called microRNAs. MicroRNAs are used by the body to help control the production of proteins; some of these proteins are involved in cell proliferation. If cell proliferation is left unchecked it can lead to cancer. All three of these functions require the protein to attach to specific DNA
