Dihydrohomoplantagin and Homoplantaginin, Major Flavonoid Glycosides from Salvia plebeia R. Br. Inhibit oxLDL-Induced Endothelial Cell Injury and Restrict Atherosclerosis via Activating Nrf2 Anti-Oxidation Signal Pathway
In this study, we evaluated the effect of homoplantaginin and its derivative dihydrohomoplantagin on oxLDL-induced endothelial cell injury and atherosclerosis in apoE-/- mice. Our results showedthat both dihydrohomoplantagin and homoplantaginin inhibited apoptosis and the increased level of ICAM-1 and VCAM-1 in oxLDL-stimulated HUVECs and the plaque endothelium of apoE-/- mice. Additionally, both of them restricted atherosclerosis development of apoE-/- mice. Mechanistic studies showed that oxLDL-induced the increase in ROS production, phosphorylation of ERK and nuclear translocation of NF-κB in HUVECs was significantly i...

Apigenin Modulates Dendritic Cell Activities and Curbs Inflammation Via RelB Inhibition in the Context of Neuroinflammatory Diseases
AbstractNeuroinflammation leads to tissue injury causing many of the clinical symptoms of Multiple Sclerosis, an autoimmune disorder of the central nervous system (CNS). While T cells, specifically Th1 and Th17 cells, are the ultimate effectors of this disease, dendritic cells (DCs) mediate T cell polarization, activation, etc. In our previous study, Apigenin, a natural flavonoid, has been shown to reduce EAE disease severity through amelioration of demyelination in the CNS as well as the sequestering of DCs and other myeloid cells in the periphery. Here, we show that Apigenin exerts its effects possibly through shifting D...

Genistein suppresses psoriasis-related inflammation through a STAT3-NF- κB-dependent mechanism in keratinocytes.
In this study, we investigated the effects of genistein on imiquimod (IMQ)-induced psoriasis-like skin lesions in vivo and explored the mechanisms underlying those effects in vitro. It was found that genistein can significantly improve IMQ-induced pathological scores of cutaneous skin lesions in mice, reduce epidermal thickness, and inhibit the expression of inflammatory factors，including interleukin (IL)-1β, IL-6, tumour necrosis factor-alpha (TNF-α), chemokine ligand 2 (CCL2), IL-17 and IL-23. In vitro studies, genistein inhibited the proliferation of human keratinocyte HaCaT cells and inhibited the expression of inf...

Orientin-mediated Nrf2/HO-1 signal alleviates H2O2-induced oxidative damage via induction of JNK and PI3K/AKT activation.
Abstract Oxidative stress is closely associated with the pathogenesis of various diseases. Orientin (Ori), a flavonoid component isolated from natural plants, possesses antioxidant activity. Accordingly, we focused on exploring the potential therapeutic effects of Ori on hydrogen peroxide (H2O2)-induced oxidative impairment in RAW 264.7 cells and the underlying antioxidative mechanisms. Our findings suggested that Ori exposure effectively alleviated H2O2-stimulated cytotoxicity, inhibited reactive oxygen species (ROS) generation, and glutathione (GSH) depletion, which were involved in induction of heme oxygenase-1...

The Involvement of p62-Keap1-Nrf2 antioxidative signaling pathway and JNK in the protection of natural flavonoid quercetin against hepatotoxicity.
Abstract Quercetin, one of the most abundant dietary flavonoids, is reported to have protective function against various hepatotoxicants-induced hepatotoxicity. The present study aims to investigate the critical role of nuclear factor erythroid 2-related factor 2 (Nrf2) antioxidative signaling pathway in the protection of quercetin against hepatotoxicity. Quercetin prevented the cytotoxicity induced by a variety of hepatotoxicants including clivorine (Cliv), acetaminophen (APAP), ethanol, carbon tetrachloride (CCl4), and toosendanin (TSN) in human normal liver L-02 cells. Quercetin induced the nuclear translocatio...
