Glioblastoma is the most common and malignant form of primary astrocytoma. Upon
investigation of the insulin-like growth factor (IGF) pathway, we found the IGF2BP3/IMP3
transcript and protein to be up-regulated in GBMs but not in lower grade astrocytomas (p<
0.0001). IMP3 is an RNA binding protein known to bind to the 5′-untranslated region of IGF-
2 mRNA, thereby activating its translation. Overexpression-and knockdown-based studies
establish a role for IMP3 in promoting proliferation, anchorage-independent growth …
