Core Tip

Core tip: Forkhead box O (FoxO)3a has recently been highlighted as a critical protein that regulates numerous cell functions from proliferation/apoptosis to stress-resistance and aging. FoxO3a has been found to be deregulated in several diseases and FoxO3a targeting approaches are currently underway to treat various types of cancers. This review will describe the current concept of FoxO3a’s pathological role in various diseases and elucidate the regulatory mechanisms involved. It will also provide the clinical significance and strategies to target FoxO3a to limit the progression of human diseases.
