6、2体外研究 Mangiferin is glucosylxanthone extracted from plants of the Anacardiaceae and Gentianaceae families. Mangiferin (50M) significantly increases Nrf2 protein accumulation in HL-60 cells, particularly in the nucleus. Mangiferin alsoenhances the binding of Nrf2 to an antioxidant response element (A

7、RE), significantly up-regulates NAD(P)H:quinoneoxidoreductase 1 (NQO1) expression and reduces intracellular ROS in HL60 cells. Mangiferin alone dose-dependentlyinhibits the proliferation of HL-60 cells. In mononuclear cells (MNCs), Mangiferin significantly relieves oxidative stress,but attenuates et

8、oposide-induced cytotoxicity1. Mangiferin is a natural phytopolyphenol that exhibits variouspharmacological properties. Mangiferin is present in several plant species such as Mangifera indica, Iris unguicularis,and Anemarrhena asphodeloides. Mangiferin downregulates TNF-induced MMP-9 mRNA and protei

9、n expressionby suppressing NF-B activity, consequently suppressing the invasion of LNCaP cells.To assess whether Mangiferininfluences the viability of LNCaP cells, MTT assay is performed 24 h after treatment with different concentrations ofMangiferin in the presence or absence of TNF- in serum and s

10、erum-free conditions. There are no cytotoxic evidentin LNCaP cells treated with up to 400 M of Mangiferin alone under both serum and serum-free conditions.Additionally, in the presence of TNF- (20 ng/mL), Mangiferin does not affect cell viability. Mangiferin (400 M)treatment significantly decreases

11、the NF-B luciferase activity in TNF-stimulated LNCaP cells. Pretreatment withMangiferin (400 M) for 1 h significantly decreases TNF-induced NF-B activity. The RT-PCR shows that Mangiferin(400 M) significantly suppresses the TNF-induced MMP-9 expression in LNCaP cells2.PROTOCOLCell Assay 2 LNCaP cell

Briefly, LNCaP cells (1105 cells/mL) are plated onto 24 well plates and incubatedovernight in serum and serum-free RPMI media. The cells are treated with the indicated conc

13、entrations of Mangiferin(100, 200, and 400 M) for 1 h and then stimulated with TNF- (20 ng/mL) for 24 h. Then, the cells are incubatedwith a solution of 0.5 mg/mL MTT and incubation for 45 min at 37C and 5% CO2. Supernatant is removed and theformation of formazan is observed by monitoring the signal
