Troxerutin is a bioflavonoid, which can be used to treat venous disorders, thrombosis and cerebrovascular diseases. Recent studies have demonstrated that it may also be used to prevent edemas. However, it is not known whether troxerutin protects against the cardiomyopathic complications of diabetes. In the present study, a rat model of type 2 diabetes was used to investigate the potential for troxerutin to protect against diabetic cardiomyopathy, through changes to nuclear factor‑κB (NF‑κB) expression...

Recent clinical and experimental evidences strongly acclaim Yes-associated protein (Yap), a key oncogenic driver in liver carcinogenesis, as a therapeutic target. Of the known multiple schemes to inhibit Yap activity, activation of Mammalian Sterile 20-like Kinase 1 (Mst1), an upstream regulator of Yap, appears to be a promising one. In this study, we hypothesize that morin, a bioflavonoid, mediates its anti-cancer effect through the activation of Mst1/hippo signaling in liver cancer cells. To test this hypothesis, both full length Mst1 (F-Mst1) and kinase active N-terminal Mst1 (N-Mst1)-overexpressed HepG2 cells were used...

Osteoarthritis (OA) is a degenerative joint disease characterized by a progressive articular cartilage degradation manifested with significant functional impairment in consort with signs and symptoms of inflammation, stiffness, and loss of mobility. Current OA management is inadequate due to the lack of nominal therapies proven to be effective in hampering disease progression where symptomatic therapy focused intervention masks the primary etiology leading to irreversible structural damage. In this study, we describe the effect of UP1306, a composition containing a proprietary blend of two standardized extracts from the heartwood of Acacia catechu and the root bark of Morus alba, in maintaining joint structural integrity and alleviating OA associated symptoms in monosodium-iodoacetate (MIA)-induced rat OA disease model...

The bioflavonoid apigenin has been shown to possess cancer-preventive and anti-cancer activities. In a drug screening, we found that apigenin can inhibit Wnt/β-catenin signaling, a pathway that participates in pivotal biological functions, which dis-regulation results in various human diseases including cancers. However, the underlying mechanism of apigenin in this pathway and its link to anti-cancer activities remain largely unknown. Here we showed that apigenin reduced the amount of total, cytoplasmic, and nuclear β-catenin, leading to the suppression in the β-catenin/TCF-mediated transcriptional activity, the expression of Wnt target genes, and cell proliferation of Wnt-stimulated P19 cells and Wnt-driven colorectal cancer cells...

Naringin is a bioflavonoid that is rich in citrus plants and possesses enormous health benefits. However, the use of naringin as a nutraceutical is significantly limited by its low bioavailability. In this study, a novel water-soluble ternary nanoparticle material consisting of amylose, α-linoleic acid and β-lactoglobulin was developed to encapsulate naringin to improve its bioavailability. The physicochemical characteristics of the ternary nanoparticle-naringin inclusion complex were analysed by ultraviolet-visible spectroscopy (UV), Fourier transform infrared spectroscopy (FT-IR), differential scanning calorimetry (DSC), high-resolution transmission electron microscopy (TEM), X-ray diffractometry (XRD) and particle size distribution...

BACKGROUND: Liver fibrosis is one of the major complications from upper right quadrant radiotherapy. MicroRNA-17-5p (miR-17-5p) is hypothesized to act as a regulator of hepatic stellate cell (HSCs) activation by activation of the canonical Wnt-β-catenin pathway. Diosmin (Dios), a citrus bioflavonoid, is known to possess potent antioxidant, anti-inflammatory, and anti-apoptotic properties. PURPOSE: To explore the molecular mechanisms that underlie radiation-induced liver fibrosis, and to evaluate the possible influence of Dios on the miR-17-5p-Wnt-β-catenin signaling axis during fibrogenesis provoked by irradiation (IRR) in rats...

Rutin is a bioflavonoid found in medicinal plants used to reduce anxiety. Evidence is lacking of rutin's anxiolytic-like activity, putative mechanism(s) of action, and neural sites of effects. The basolateral amygdala (BLA) is the main brain region that regulates anxiety, through GABAA/benzodiazepine (BDZ) receptors, which are modulated by flavonoids. Therefore, the main aim of this study was to investigate whether the anxiolytic-like effect of rutin involves GABAA/BDZ receptors in the BLA. Rutin was administered systemically (30-1000 mg/kg, intraperitoneal) or microinjected into the BLA (16 nmol/4 µl, intracerebral), and its effects were assessed in the elevated plus-maze and open-field tests...

One of the pivotal mechanisms projected for bioflavonoids in cancer chemoprevention is through their intervention against mutagen-DNA interaction. Recent literatures emphasize the role of troxerutin (TXER) as an emerging anticancer agent. However, there are no reports on its intervention in any carcinogen-DNA interaction. The present study investigates the possibility of TXER, in prevention of 2-aminoanthracene (2-AA) contact with DNA. Steady state and time resolved fluorescence spectroscopy results, highlight the direct contact of 2-AA with DNA, while presence of TXER prevented this interaction...

Quercetin, a bioflavonoid contained in several vegetables daily consumed, has been studied for long time for its antiinflammatory and anticancer properties. Quercetin interacts with multiple cancer-related pathways such as PI3K/AKT, Wnt/β-catenin and STAT3. These pathways are hyperactivated in primary effusion lymphoma (PEL), an aggressive B cell lymphoma whose pathogenesis is strictly linked to the oncogenic virus Kaposis' Sarcoma-associated Herpesvirus (KSHV). In this study, we found that quercetin inhibited PI3K/AKT/mTOR and STAT3 pathways in PEL cells, and as a consequence, it down-regulated the expression of the prosurvival cellular proteins such as c-FLIP, cyclin D1 and cMyc...
