Hong Wu, MD, PhD (Damon Runyon Fellow ‘92-‘95, Former Sponsor) of UCLA’s Jonsson Comprehensive Cancer Center, Los Angeles, demonstrated that the loss or reduction of the tumor suppressor gene PTEN is involved in the transformation of benign nerve tumors called neurofibromas into a deadly form of sarcoma, malignant peripheral nerve sheath tumors.  In the future, the researchers plan to screen drugs that may be able to target the PTEN pathway and block signals that instruct cells to change from a benign state to a malignant one.  These findings were published in the journal Proceedings of the National Academy of Sciences.
