Besides, RACK1 can modulate PI3K/Akt signaling or activates Akt to propel cell proliferation and invasion/metastasis in VEGF/Flt1-mediated endothelial cells [26], mouse hepatocarcinoma cells [27], renal cell carcinoma [28], and some other cancers [29, 30]. This evidence concerns the gene RACK1 and renal cell carcinoma.
