Red wine compound piceatannol inhibits the development of fat cellsPosted on Monday, 16 April, 2012 by anthony
Piceatannol (3,4,3′,5′-tetrahydroxy-trans-stilbene), a metabolite of resveratrol found in red wine, grapes, rhubarb, passion fruit seeds, blueberries, and peanuts appears to inhibit adipogenesis – the process by which preadipocytes (immature fat cells) develop into adipocytes (mature fat cells) – in part through the inhibition of insulin receptor activity in preadipocytes (Kwon et al., 2012). The research suggests that piceatannol may therefore be beneficial for the treatment/prevention of obesity.
Why is the inhibition of adipogenesis important?
Any inhibition of adipogenesis is important since when adipocyte numbers increase significantly – as is the case with obesity - there is often a concomitant increase in the release of pro-inflammatory molecules, fatty acids and hormones which may lead to a permanent pro-inflammatory state. It is believed that the inflammation associated with obesity may play a significant role in a number of health conditions including, metabolic syndrome, type 2 diabetes, atherosclerosis, and nonalcoholic fatty liver disease.
Other health benefits of Piceatannol
Piceatannol has been shown to have a number of potential health benefits including: 1) the suppression of both the growth and metastasis (spread) of cancer cells (Kita et al., 2012; Vo et al., 2010; Kim et al., 2009; Woolter et al., 2002); 2) beneficial effects in the treatment of some cardiovascular diseases (Woo et al 2010); 3) an anti-atherosclerotic effect and beneficial effects in the treatment of atherosclerosis (hardening of the arteries) (Choi et al 2010; Lee et al., 2009); 4) possible beneficial effects in the treatment of inflammatory bowel diseases (Kim et al., 2008), and; 5) protection against Beta-amyloid induced oxidative stress and cell death (Kim et al., 2007).
