Abstract
The edible Rosa hybrida (RH) petal is utilized in functional
foods and cosmetics. Although the biological function of RH petal extract is
known, mechanism of action studies involving tumor-associated angiogenesis have
not yet been reported. Herein, we investigated the regulatory effect of the
ethanol extract of RH petal (EERH) on tumor growth and tumor angiogenesis
against bladder cancer. EERH treatment inhibited the bladder carcinoma T24 cell
and 5637 cell proliferation because of G1-phase cell cycle arrest by
inducing p21WAF1 expression and reducing cyclins/CDKs level. EERH regulated
signaling pathways differently in both cells. EERH-stimulated suppression of T24
and 5637 cell migration and invasion was associated with the decline in
transcription factor-mediated MMP-9 expression. EERH oral administration to
xenograft mice reduced tumor growth. Furthermore, no obvious toxicity was
observed in acute toxicity test. Decreased CD31 levels in EERH-treated tumor
tissues led to examine the angiogenic response. EERH alleviated VEGF-stimulated
tube formation and proliferation by downregulating the VEGFR2/eNOS/AKT/ERK1/2
cascade in HUVECs. EERH impeded migration and invasion of VEGF-induced HUVECs,
which is attributed to the repressed MMP-2 expression. Suppression of
neo-microvessel sprouting, induced by VEGF, was verified by treatment with EERH
using the ex vivo aortic ring assay. Finally, kaempferol was identified as the
main active compound of EERH. The present study demonstrated that EERH may aid
the development of antitumor agents against bladder cancer.

Piceatannol, a Natural Analog of Resveratrol, Exerts Anti-angiogenic Efficiencies by Blockage of Vascular Endothelial Growth Factor Binding to Its Receptor. Molecules 2020; 25:molecules25173769. [PMID: 32824997 PMCID: PMC7504081 DOI: 10.3390/molecules25173769] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2020] [Revised: 08/17/2020] [Accepted: 08/17/2020] [Indexed: 12/21/2022] Open
Abstract
Piceatannol is also named as trans-3,4,3′,5′-tetrahydroxy-stilbene, which is a natural analog of resveratrol and a polyphenol existing in red wine, grape and sugar cane. Piceatannol has been proved to possess activities of immunomodulatory, anti-inflammatory, antiproliferative and anticancer. However, the effect of piceatannol on VEGF-mediated angiogenesis is not known. Here, the inhibitory effects of piceatannol on VEGF-induced angiogenesis were tested both in vitro and in vivo models of angiogenesis. In human umbilical vein endothelial cells (HUVECs), piceatannol markedly reduced the VEGF-induced cell proliferation, migration, invasion, as well as tube formation without affecting cell viability. Furthermore, piceatannol significantly inhibited the formation of subintestinal vessel in zebrafish embryos in vivo. In addition, we identified the underlying mechanism of piceatannol in triggering the anti-angiogenic functions. Piceatannol was proposed to bind with VEGF, thus attenuating VEGF in activating VEGF receptor and blocking VEGF-mediated downstream signaling, including expressions of phosphorylated eNOS, Erk and Akt. Furthermore, piceatannol visibly suppressed ROS formation, as triggered by VEGF. Moreover, we further determined the outcome of piceatannol binding to VEGF in cancer cells: piceatannol significantly suppressed VEGF-induced colon cancer proliferation and migration. 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.
