An international team of scientists has uncovered a mechanism by which acute myeloid leukemia (AML) cells sustain their growth. AML cells prevent the synthesis of proteins that suppress their growth by forcibly isolating the mRNAs that encode such proteins within structures known as P-bodies. These findings offer a novel perspective into the survival mechanisms of AML and possibilities for new anti-cancer therapies.
