The Isothiocyanate Sulforaphane Depends on the Nrf2/ γ-GCL/GSH Axis to Prevent Mitochondrial Dysfunction in Cells Exposed to Methylglyoxal.
The Isothiocyanate Sulforaphane Depends on the Nrf2/γ-GCL/GSH Axis to Prevent Mitochondrial Dysfunction in Cells Exposed to Methylglyoxal. Neurochem Res. 2021 Jan 03;: Authors: Brasil FB, Gobbo RCB, de Almeida FJS, Luckachaki MD, Dos Santos Petry F, de Oliveira MR Abstract Methylglyoxal (MG) is a reactive dicarbonyl presenting both endogenous (e.g. glycolysis) and exogenous (e.g. food cooking) sources. MG induces neurotoxicity, at least in part, by affecting mitochondrial function, including a decline in the oxidative phosphorylation (OXPHOS) system activity, bioenergetics failure, and redox disturba...

Chalcone flavokawain A attenuates TGF- β1-induced fibrotic pathology via inhibition of ROS/Smad3 signaling pathways and induction of Nrf2/ARE-mediated antioxidant genes in vascular smooth muscle cells.
In this study, flavokawain A (FKA, 2-30 μM), a naturally occurring chalcone in kava extracts, was evaluated for its anti-fibrotic and antioxidant properties in TGF-β1-stimulated vascular smooth muscle (A7r5) cells, as well as its underlying molecular mechanism of action. Immunofluorescence data showed down-regulated F-actin expression with FKA treatment in TGF-β1-stimulated A7r5 cells. Western blotting demonstrated that FKA treatment suppressed the expression of α-SMA and fibronectin proteins under TGF-β1 stimulation. Findings from wound-healing and invasion experiments showed that FKA inhibits TGF-β1-mediated migra...

Ferulic Acid Protected from Kidney Ischemia Reperfusion Injury in Mice: Possible Mechanism Through Increasing Adenosine Generation via HIF-1 α
AbstractFerulic acid (FA), derived from fruits and vegetables, is well-known as a potent antioxidant of scavenging free radicals. However, the role and underlying mechanism of FA on kidney ischemia reperfusion (I/R) injury are limited. Here, we explored the effects of FA on kidney I/R injury. The kidney I/R injury models were carried out by clamping bilateral pedicles for 35  min followed by reperfusion for 24 h. Mice were orally pretreated with different doses of FA for three times 24 h before I/R. The renal function was assessed by serum creatine (Scr) and blood urea nitrogen (BUN). Kidney histology was examined by he...

Isoquercitrin promotes the osteogenic differentiation of osteoblasts and BMSCs via the RUNX2 or BMP-pathway.
Authors: Li M, Zhang C, Li X, Lv Z, Chen Y, Zhao J Abstract Isoquercitrin is widely present in fruits, vegetables and medicinal herbs. As a natural phytoestrogen, isoquercitrin has been considered a possible osteoporosis prevention option to avoid the risk of hormone therapy. In this work, we studied the effects of isoquercitrin on the cell proliferation and osteogenic differentiation of osteoblasts and bone mesenchymal stem cells (BMSCs), as well as the molecular mechanism of isoquercitrin action. The cell proliferation of osteoblasts and BMSCs was promoted by isoquercitrin at low concentrations. High concentratio...

Sulforaphane Promotes Mitochondrial Protection in SH-SY5Y Cells Exposed to Hydrogen Peroxide by an Nrf2-Dependent Mechanism
AbstractSulforaphane (SFN; C6H11NOS2) is an isothiocyanate found in cruciferous vegetables, such as broccoli, kale, and radish. SFN exhibits antioxidant, anti-apoptotic, anti-tumor, and anti-inflammatory activities in different cell types. However, it was not previously demonstrated whether and how this natural compound would exert mitochondrial protection experimentally. Therefore, we investigated here the effects of a pretreatment (for 30  min) with SFN at 5 μM on mitochondria obtained from human neuroblastoma SH-SY5Y cells exposed to hydrogen peroxide (H2O2) at 300  μM for 24 h. We found that SFN prevented loss of...

Potential role of nucleoside diphosphate kinase in myricetin-induced selective apoptosis in colon cancer HCT-15  cells.
In this study, we evaluated the anti-cancer effects induced by MYR treatment in colon cancer HCT-15 cells. To detect cell proliferation, we conducted MTT assay and real time-cell electronic sensing (RT-CES). We next performed comet assay and Annexin V and PI staining to detect cellular apoptotic features. After that, we conducted two-dimensional electrophoresis (2-DE) analysis to identify apoptotic proteins. The results of this analysis revealed that eight spots were differentially expressed. Among the spots, we selected nucleoside diphosphate kinase (NDPK) for further investigation, as it has been shown to regulate canc...

Molecules, Vol. 22, Pages 1285: Fisetin Induces Apoptosis Through p53-Mediated Up-Regulation of DR5 Expression in Human Renal Carcinoma Caki Cells
Kwon Fisetin is a natural compound found in fruits and vegetables such as strawberries, apples, cucumbers, and onions. Since fisetin can elicit anti-cancer effects, including anti-proliferation and anti-migration, we investigated whether fisetin induced apoptosis in human renal carcinoma (Caki) cells. Fisetin markedly induced sub-G1 population and cleavage of poly (ADP-ribose) polymerase (PARP), which is a marker of apoptosis, and increased caspase activation. We found that pan-caspase inhibitor (z-VAD-fmk) inhibited fisetin-induced apoptosis. In addition, fisetin induced death receptor 5 (DR5) expression at the trans...
