Angioproliferative tumors induced by the Kaposi’s Sarcoma associated herpesvirus (KSHV) have been successfully treated with rapamycin, which provided direct evidence of the clinical activity of mTOR inhibitors in human malignancies. However, prolonged mTOR inhibition may raise concerns in immunocompromised patients, including AIDS-KS. Here, we explored whether KSHV-oncogenes deploy cell-type specific signaling pathways activating mTOR, which could be exploited to halt KS development while minimizing immune suppressive effects. We found that PI3Kγ, a PI3K isoform exhibiting restricted tissue distribution, is strictly required for signaling from the KSHV-encoded vGPCR oncogene to Akt/mTOR. Indeed, by using an endothelial-specific gene delivery system modeling KS development, we provide genetic and pharmacological evidence that PI3Kγ may represent a suitable molecular target for therapeutic intervention in KS.
