The phosphatidylinositol-4,5-bisphosphate 3-kinase (PI3K)/serine/threonine-specific protein kinase (Akt)/mammalian target of rapamycin (mTOR) pathway regulates cell proliferation and cell growth and is often stimulated in cancer, which makes it an important target pathway for cancer therapies [1, 2]. Here, DYRK1A is linked to cancer.
