Piceatannol has potent anti-inflammatory, immunomodulatory, anticancer and antiproliferative effects. However, little is known about the mechanism by which piceatannol inhibits invasion and metastasis. The aim of the current study was to investigate the effects of piceatannol on the expression of
Piceatannol (3,5,3',4'-tetrahydroxy- trans-stilbene), a resveratrol analogue, is a polyphenol present in the skins of grapes and in wine and other foods. The present study aimed to investigate for the first time the cardioprotective effects of piceatannol on vascular smooth muscle cells (VSMC). The
Piceatannol, a bioactive component in grape and blueberry, was examined for its potential in decreasing the inflammatory activities in adipocytes using a cocultured adipocyte and macrophage system, and suppressing tumor necrosis factor-α (TNF-α)-mediated inflammation and the related insulin
The intensity and duration of an inflammatory response depends on the balance of factors that favor perpetuation versus resolution. At sites of inflammation, neutrophils adherent to other cells or matrix components are exposed to tumor necrosis factor-alpha (TNFalpha). Although TNFalpha has been
Neutrophils up-regulate beta2 integrins like CD11b/CD18 in response to lipopolysaccharide (LPS). Up-regulation of beta2 integrins causes neutrophils to adhere to surfaces, and to release superoxide anion (O2-). When neutrophils are exposed to LPS plus plasma under conditions not favorable for
Piceatannol is an anti-inflammatory and anti-proliferative plant-derived stilbene. Heme oxygenase-1 (HO-1) is a cytoprotective enzyme to activate by various phytochemicals. In this study, we examined the ability of piceatannol to upregulate HO-1 expression in endothelial cells. We found piceatannol
Inflammatory processes are involved in the etiology of diseases. We analyzed the effect of resveratrol, piceatannol, synthetic tri-acetoxystilbene (TAS), and genistein (Bonistein(TM)) on the production of inflammatory mediators including prostaglandin E2 (PGE2), tumor necrosis factor-alpha
Piceatannol (PIC), a natural analog of resveratrol (RES), is a phytochemical found in passion fruit seeds. To clarify the effects of PIC on obesity-induced inflammation in adipose tissue, we investigated the anti-inflammatory activity of PIC-related compounds (PIC, RES, and metabolites from PIC) in
Piceatannol is a phenolic stilbenoid and a metabolite of resveratrol which is found in red wine. Piceatannol (PIC) commonly exhibits anti-inflammatory, antiplatelet and antiproliferative activity. In the present study, the anti-allergic and anti-inflammatory mechanisms of PIC were investigated by
Piceatannol (PIC) is a natural hydroxylated analog of resveratrol (RSV) and considered as a potential metabolic regulator. The purpose of this study was to compare the effects of PIC and RSV on parameters affecting inflammation, oxidative stress, and sirtuins (Sirt). Male C57BL/6J mice, 20 weeks
This study investigates the molecular mechanisms of the nephroprotective effect of piceatannol (PIC) against cisplatin-induced nephrotoxicity in rats. PIC (10 mg/kg i.p.) was given for 7 days, starting 2 days before cisplatin single injection (7 mg/kg i.p.). Serum creatinine, blood urea nitrogen
Proinflammatory mediators, such as prostaglandin E(2) (PGE(2)), nitric oxide (NO), and proinflammatory cytokines [interlukin (IL)-1beta, IL-6, and tumor necrosis factor (TNF)-alpha] play pivotal roles in brain injuries. Anti-inflammatory responses are associated with significant downregulation of
The Cutibacterium acnes (also called Propionibacterium acnes, P. acnes)-induced proliferation and migration of keratinocytes contribute to acne vulgaris (AV), which is a common inflammatory skin disease that causes physical and psychological impairments. Piceatannol (3, 5, 3',
Resveratrol (Res) and its two natural analogs that are also related to Res metabolism, piceatannol (Pic) and 3,5,4'-trans-trimethoxystilbene (TMS), were compared in their ability to suppress lipopolysaccharide (LPS)-induced production of proinflammatory tumor necrosis factor-α (TNF-α) and
Growing evidence suggests that the elevation of free fatty acids, including palmitic acid (PA), are associated with inflammation and oxidative stress, which may be involved in endothelial dysfunction, characterized by the reduced bioavailability of nitric oxide (NO) synthesized from endothelial NO
