The regulatory protein 14-3-3z promotes cellular growth and survival, and high expression levels of 14-3-3z are associated with mortality in multiple cancer types. 14-3-3z binds cellular proteins in a phosphorylation-dependent manner to modulate their functions. We have been characterizing the interactome of 14-3-3z which will likely lead to candidates for novel therapies for chemoresistant cancers. Tumor cells must be able to survive in a variety of stresses within the tumor microenvironment, including hypoxia, which occurs when tumors lack adequate blood supply. Previous data from our lab suggested that 14-3-3z promotes the adaptation of tumor cells to hypoxic stress. Our hypothesis …
