Chrysin is a bioflavonoid compound found in passion flower, chamomile, propolis and honey at high levels. Post-thawed sperm quality and fertility of Chrysin-fed roosters were assessed in this study. Twenty 40-week-old male broiler breeders were randomly divided into four groups and fed basal diet supplemented with different levels of Chrysin including 0 (Ch-0), 25 (Ch-25), 50 (Ch-50) or 75 (Ch-75) mg/day for 12 consecutive weeks. Semen samples were weekly collected from 6th to 9th week of experiment to evaluate some sperm quality parameters including total and progressive motility, plasma membrane integrity and functionality (in fresh and post-thawed samples) and mitochondrial activity (only in post-thawed samples)...

Oxidative stress has been implicated in the pathogenesis of many kinds of neurodegenerative disorders, particularly Parkinson's disease. Quercetin is a bioflavonoid found ubiquitously in fruits and vegetables, and has antioxidative activity. However, the underlying mechanism of the antioxidative effect of quercetin in neurodegenerative diseases has not been well explored. Here, we investigated the antioxidative effect and underlying molecular mechanisms of quercetin on PC-12 cells. We found that PC-12 cells pretreated with quercetin exhibited an increased cell viability and reduced lactate dehydrogenase (LDH) release when exposed to hydrogen peroxide (H₂O₂)...

Inhibition of P-glycoprotein (P-gp)'s function may conduct significant changes in the prescription drugs' pharmacokinetic profiles and escalate potential risks in taking place of drug/herb-drug interactions. Computational modelling was advanced to scrutinise some bioflavonoids which play roles in herb-drug interactions as P-gp inhibitors utilising molecular docking and pharmacophore analyses. Twenty-five flavonoids were utilised as ligands for the modelling. The mouse P-gp (code: 4Q9H) was acquired from the PDB...

Intracerebral hemorrhage (ICH) contributes to 10-15% of all strokes and is a high risk factor for morbidity and mortality as compared to other subtypes of stroke, that is, cerebral ischemia and subarachnoid hemorrhage. Oxidative stress (OS)-induced neuroinflammation and neuronal cell death contribute towards the hallmarks of ICH. Spared antioxidant levels, increased inflammatory cytokines and free radicals in ICH lead to neuronal death and exaggerate the hallmarks of ICH. Intracerebroventricular (ICV) collagenase (COL-induced neuronal cell damage and cognitive deficits form a widely recognized experimental model for ICH...

Metastasis is the major cause of death from lung cancer. Quercetin, a widely distributed bioflavonoid, is well known to induce growth inhibition in a variety of human cancer cells, but how it affects lung cancer cell invasion and metastasis is unclear. Herein, we found that quercetin inhibited the migration/invasion of non-small cell lung cancer (NSCLC) cell lines and bone metastasis in an orthotopic A549 xenograft model by suppressing the Snail-mediated epithelial-to-mesenchymal transition (EMT). Moreover, survival times of animals were also prolonged after quercetin treatment...

BACKGROUND AND AIMS: To explore hepatoprotective action of curcumin (CMN, a bioflavonoid) on oxaliplatin (Oxa)-triggered mitochondrial oxidative stress and respiratory chain complexes in liver of rats. Oxa is a ubiquitously utilized platinum-based chemotherapeutic agent commonly used for the treatment of colorectal cancer. Mitochondria have recently emerged as targets for anticancer drugs in several kinds of toxicity including hepatotoxicity that can lead to neoplastic disease. There is a dearth of evidence involving the role of mitochondria in mediating Oxa-evoked hepatotoxicity and its underlying mechanism is still debatable...

Diabetes mellitus is characterized by hyperglycemia and associated complications. However, long-term diabetes control is not often sustained by currently available therapeutic approaches. Research on nanoparticle-mediated drug delivery systems is in progress. Here we have tested a ligand (argpyrimidine)-tagged drug (rutin)-encapsulated biocompatible (ethylene glycol dimers) nanoparticle for targeted drug delivery in streptozotocin-induced diabetic rats. Argpyrimidine, being an advanced glycation end product (AGE), directs the nanoparticles to interact with cell surface receptors of AGEs (RAGE) and delivers the drug into the cells...

Rhabdomyolysis is defined as dissolution of striped muscle characterized by leakage of intracellular muscle components into the circulation, which can ultimately lead to renal failure with a possible fatal outcome. This is an uncommon side effect of trabectedin which is used in second-line therapy of metastatic sarcoma after anthracycline and ifosfamide failure. Here, we describe a case of reversible rhabdomyolysis in a male patient with recurrent metastatic synovial sarcoma of the hand, with marked (18)F-FDG uptake into his skeletal muscles, after 4 cycles of trabectedin, and who at the same time was taking an alternative medicine (bioflavonoids) suspected of triggering this adverse event...

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...
