Identification Of Transcriptional Mechanisms Downstream Of Nf1 Gene Defeciency In Malignant Peripheral Nerve Sheath Tumors, Daochun Sun
Wayne State University Dissertations
Malignant peripheral nerve sheath tumor (MPNST) is a type of soft tissue sarcoma that occurs in carriers of mutations in the neurofibromatosis type I gene (Nf1) as well as sporadically. Plexiform neurofibromas in NF1 patients have a significant risk of developing into MPNSTs leading to increased morbidity and mortality from this syndrome. Surgery is the primary intervention but it is not always effective due to the tendency of MPNSTs to infiltrate the surrounding tissue or grow in an inoperable location. Neurofibromin, the protein coded by the Nf1 gene, functions as a GTPase activating protein (GAP) whose mutation leads to constitutive …
