Regulating p53 translation and function (SJ-05-0002)

St. Jude Reference #SJ-05-0002


Methods are provided for modulating the activity of p53 tumor suppressor protein by affecting p53 translational regulation. The methods involve affecting the function of a p53 5’-untranslated region (5’UTR), including its interaction with proteins such as Ribosomal Protein L26 (RPL26), nucleolin, and p53. Use of RPL26 siRNA to downregulate p53 induction is shown. These methods can be developed for treatment of cancer, neurodegenerative disorders and minimizing the negative effects of cellular stresses.
