The list of aging-associated proteins known to be involved in cancer is growing longer, according to research by investigators at Vanderbilt-Ingram Cancer Center and the National Institutes of Health (NIH). The new study, published Oct. 17 in Cancer Cell, identifies the protein SIRT2 as a tumor suppressor linked to gender-specific tumor development in mice. Along with two other “sirtuin” proteins previously linked to cancer, the new finding suggests the existence of a rare “family” of tumor suppressors.
