Cytotoxic and Apoptotic Effects of Pinostilbene and Bortezomib Combination Treatment on Human Multiple Myeloma Cells. (PubMed, Int J Mol Sci)
BTZ as well as RES and its derivatives pinostilbene (PIN) and piceatannol (PIC) decreased MM cell viability in a dose- and time-dependent manner and increased expression of cleaved proapoptotic proteins poly(ADP-ribose) polymerase 1 (PARP1) and caspase-3 in a dose-dependent manner. Expression of oxidative stress defense proteins (catalase, thioredoxin, and superoxide dismutase) in RPMI 8226 cells were reduced after 24 h treatment, and cytotoxic effects of the treatment were ameliorated by antioxidant N-acetylcysteine (NAC), suggesting the treatment impacts antioxidant levels in RPMI 8226 cells. Our results suggest that this combination of BTZ and PIN decreases MM cell viability synergistically by inducing apoptosis and oxidative stress in MM cells.

The Mechanisms of Piceatannol in Inhibiting the Malignant Biological Characteristics of Acute Myeloid Leukemia Cells (PubMed, Zhongguo Shi Yan Xue Ye Xue Za Zhi)
Piceatannol can inhibit the proliferation of AML cells and induce programmed death, which may be related to the inhibition of Akt/NF-κB signaling pathway, the hydrolysis of caspase-3 and the down-regulation of Bcl-2 protein expression, and the suppression of the expression of some drug resistance genes.

The Antiproliferative Activity of Adiantum pedatum Extract and/or Piceatannol in Phenylhydrazine-Induced Colon Cancer in Male Albino Rats: The miR-145 Expression of the PI-3K/Akt/p53 and Oct4/Sox2/Nanog Pathways. (PubMed, Molecules)
However, the administration of AP or P or AP + P as therapy or prophylaxis significantly ameliorated these changes and upregulated the colonic mir-145 and mRNA expression of P53 and PDCD-4 while downregulating the colonic mRNA expression of PI3K, AKT, c-Myc, CK-20, SOX-2, OCT-4, and NanoG compared to the PHZ group. These findings suggest that the candidate drugs may exert their anti-cancer effects through multiple mechanisms, including antioxidant and apoptotic activities.

Protective Effects of Piceatannol on DNA Damage in Benzo[a]pyrene-Induced Human Colon Epithelial Cells. (PubMed, J Agric Food Chem)
The upregulation of phase II detoxification enzymes, such as nicotinamide adenine dinucleotide phosphate (NADPH) and quinone oxidoreductase 1 (NQO1), and the antioxidative enzyme, heme oxygenase 1 (HO-1), via the activation of the nuclear factor erythroid 2-related factor 2 (Nrf2) pathway was observed in the PIC-treated group. Our results suggest that PIC is a potential CRC-blocking agent due to its ability to alleviate DNA damage, decrease intracellular ROS production, modulate the metabolism and detoxification of B[a]P, and activate the Nrf2 signaling pathway in B[a]P-induced NCM460 cells.

Inhibition of Colorectal Cancer Cell Proliferation by Treatment with Itadori Leaf Extract. (PubMed, J Oleo Sci)
Itadori extracts are rich in neochlorogenic acid and rutin and also contain quercetin and piceatannol. These polyphenols are thought to be involved in the observed DNA fragmentation and caspase 3/7 activation in colon cancer cells and may thus have anticancer effects. There is hence scope for development of the leaf of itadori, which currently has only a few known uses, as a novel anti-tumor therapeutic.

Main Determinants Affecting the Antiproliferative Activity of Stilbenes and Their Gut Microbiota Metabolites in Colon Cancer Cells: A Structure-Activity Relationship Study. (PubMed, Int J Mol Sci)
The antiproliferative IC values of pterostilbene, oxy-resveratrol, piceatannol, resveratrol, dihydroresveratrol, lunularin, 3,4'-dihydroxy-trans-stilbene, pinosylvin, dihydropinosylvin, 4-hydroxy-trans-stilbene, 4-hydroxydibenzyl, 3-hydroxydibenzyl, and 4-trans-stilbenemethanol were calculated...These results (i) suggest that gut microbiota metabolism determines the antiproliferative effects of dietary stilbenes. Therefore, RSV consumption might exert different effects in individuals depending on their gut microbiota metabotypes associated with RSV metabolism, and (ii) could help design customized drugs with a stilbenoid and (or) dibenzyl core against colorectal cancer.

Piceatannol induces apoptotic cell death through activation of caspase-dependent pathway and upregulation of ROS-mediated mitochondrial dysfunction in pancreatic cancer cells. (PubMed, Mol Biol Rep)
Our results show that piceatannol has an anti-cancerogenic effect on PANC-1 and MIA PaCa-2 cells, and exerts this effect by suppressing proliferation and inducing apoptosis. Therefore, piceatannol could be considered to be a potential chemotherapeutic agent candidate for the treatment and prevention of PC.

Piceatannol, a Dietary Polyphenol, Alleviates Adipose Tissue Loss in Pre-Clinical Model of Cancer-Associated Cachexia via Lipolysis Inhibition. (PubMed, Nutrients)
Moreover, piceatannol protected tumor-bearing mice against weight-loss in early stages of CAC largely through preserving adipose tissue, with no effect on survival. This study demonstrates the use of a dietary compound to preserve adipose in models of early stage CAC and provides groundwork for further investigation of piceatannol or piceatannol-rich foods as alternative medicine in the preservation of body fat mass and future CAC therapy.

Synergistic Effects of Resveratrol Derivatives with Bortezomib on Reducing Viability and Inducing Apoptosis in Multiple Myeloma Cells. (PubMed, FASEB J)
We found that BTZ as well as RES and its derivatives pinostilbene (PIN) and piceatannol (PIC) decreased MM cell viability in a dose- and time-dependent manner and increased expression of cleaved proapoptotic proteins PARP1 and caspase-3 in a dose-dependent manner. We screened different combinations of RES derivatives with BTZ for synergistic effects on MM viability using CompuSyn and selected the combination of 5 nM BTZ and 5 μM PIN for further assessment as a synergistic treatment. In conclusion, a combination of low doses of BTZ and PIN synergistically decreases MM cell viability, possibly through inducing apoptosis.

Piceatannol, a Structural Analog of Resveratrol, Is an Apoptosis Inducer and a Multidrug Resistance Modulator in HL-60 Human Acute Myeloid Leukemia Cells. (PubMed, Int J Mol Sci)
Our findings also imply that HL-60 cells are able to acquire resistance to piceatannol toxicity via mechanisms related to MRP1 activity. Our results suggest that the use of piceatannol as a potential chemotherapeutic agent may be associated with the risk of multidrug resistance, warranting its use in combination with other chemotherapeutic agents.

Long-Term Oral Administration of Piceatannol (3,5,3',4'-Tetrahydroxystilbene) Attenuates Colon Tumor Growth Induced by Azoxymethane Plus Dextran Sulfate Sodium in C57BL/6J Mice. (PubMed, Nutr Cancer)
In mice administered piceatannol (12.5 mg/kg), the tumor number, tumor area, and Ki-67-positive cell numbers decreased by 30.1%, 57.2%, and 89.1%, respectively, colon MCP-1 and PD-1 levels showed reductions of 43.8% and 70.9%, respectively, and COX-2-positive cell numbers declined by 60.2%. The inhibitory effects of piceatannol on AOM/DSS-induced colon tumor growth appear to be associated with reductions in colon MCP-1 and PD-1 levels through the downregulated expression of COX-2 in the tumor microenvironment.

Comparison of the Effects of Resveratrol and Its Derivatives on the Radiation Response of MCF-7 Breast Cancer Cells. (PubMed, Int J Mol Sci)
The aim of this study was to investigate whether the stilbene derivatives piceid, resveratrol, and piceatannol have a radiosensitising effect on breast cancer cells (MCF-7)...This was due to a significant decrease in the activity of antioxidant enzymes, which resulted in the accumulation of formed reactive oxygen species (ROS). The effect of resveratrol and IR enhanced the expression of apoptotic genes, such as Bax, p53, and caspase 8, leading to apoptosis.

Real-Time Analysis of Polyphenol-Protein Interactions by Surface Plasmon Resonance Using Surface-Bound Polyphenols. (PubMed, Chemistry)
A selection of bioactive polyphenols of different structural classes, such as the ellagitannins vescalagin and vescalin, the flavanoids catechin, epicatechin, epigallocatechin gallate (EGCG), and procyanidin B2, and the stilbenoids resveratrol and piceatannol, were chemically modified to bear a biotin unit for enabling their immobilization on streptavidin-coated sensor chips. The types and levels of SPR responses unveiled major differences in the association, or lack thereof, and dissociation between a given protein analyte and different polyphenolic ligands. Thus, this multi-analysis SPR technique constitutes a valuable methodology to rapidly screen and qualitatively compare various polyphenol-protein interactions.

Piceatannol attenuates fat accumulation and oxidative stress in steatosis-induced HepG2 cells. (PubMed, Curr Res Food Sci)
Moreover, piceatannol significantly suppressed FA-induced oxidative stress and inhibited phosphorylation of c-Jun N-terminal kinase (JNK) and extracellular signal-regulated kinases 1/2 (ERK1/2). Overall, it is suggested that piceatannol reduced fat accumulation in steatosis-induced HepG2 cells by suppressing lipogenesis (SREBP1 and ACC) and FA uptake (CD36), and promoting FAs oxidation (FXR, PPARα and CPT1α).

Piceatannol suppresses proliferation and induces apoptosis by regulation of the microRNA‑21/phosphatase and tensin homolog/protein kinase B signaling pathway in osteosarcoma cells. (PubMed, Mol Med Rep)
In addition, we further verified that phosphatase and tensin homolog (PTEN), a tumor suppressor gene, is the functional target of miR‑21 and Pice blocks the PTEN/AKT signaling pathway through inhibiting miR‑21 expression in OS cells. Our findings suggested that Pice may exert anticancer effects on OS cells via mediating the miR‑21/PTEN/AKT signaling pathway and could be considered to be a potential anticancer agent for treating OS.

Piceatannol, a Natural Analog of Resveratrol, Exerts Anti-angiogenic Efficiencies by Blockage of Vascular Endothelial Growth Factor Binding to Its Receptor. (PubMed, Molecules)
Thus, these lines of evidence supported the conclusion that piceatannol could down regulate the VEGF-mediated angiogenic functions with no cytotoxicity via decreasing the amount of VEGF binding to its receptors, thus affecting the related downstream signaling. Piceatannol may be developed into therapeutic agents or health products to reduce the high incidence of angiogenesis-related diseases.
