WebIn glioma, PTEN mutations occur in approximately 44% of high-grade tumors, whereas mutations are rare in lower grade astrocytic tumors. PTEN mutations are found in 12–15% of primary prostate tumors and in 60% of metastatic prostate cancer. Thus, similar to glioma, PTEN loss in prostate cancer is associated with a more aggressive tumor. WebRecurrent point mutations in SPOP define a distinct molecular subclass of prostate cancer. Here, we describe a mouse model showing that mutant SPOP drives prostate tumorigenesis in vivo. ... Conditional expression of mutant SPOP in the prostate dramatically altered phenotypes in the setting of Pten loss, with early neoplastic lesions (high ...
