Several studies have now confirmed that PCAT6 is not only highly expressed in a variety of human cancers but may also act through miRNA sponges to activate the Wnt/β-catenin signaling pathway and PI3K/Akt/mTOR pathway, which in turn affects cell proliferation, migration, invasion, cycle, and apoptosis [42,43]. The gene discussed is AKT1; the disease is cancer.
