The results showed that fucoxanthin could upregulate the mRNA and protein levels of the cytoprotective genes and promote the nuclear translocation of Nrf2, which could be inhibited by the PI3K inhibitor of “type”:”entrez-nucleotide”,”attrs”:”text”:”LY294002″,”term_id”:”1257998346″,”term_text”:”LY294002″LY294002. Pretreatment of fucoxanthin resulted in decreased LDH leakage and intracellular ROS content but enhanced intracellular reduced glutathione. Interestingly, pretreatment using fucoxanthin guarded against the oxidative damage in a nonconcentration-dependent manner, with fucoxanthin of 5 tvalue smaller than 0.05. 3. Results 3.1. Effects P7C3-A20 cost of HTreatment in the Viability of L02 Cells L02 cells had been treated with H2O2 at different concentrations (100, 200, 400, 600, 800, 1000, 1200, and 1600 P 0.01).

Treatment of VE (50 P 0.01). Pretreatment with aforementioned several concentrations of fucoxanthin led to the GSH articles of 110.69 4.39%, 120.98 6.72%, 103.97 7.12%, and 96.05 5.59%, respectively (weighed against model group,P 0.01).

After getting pretreated with several above mentioned concentrations of fucoxanthin, the ROS articles slipped to 132.60 16.55%, 96.61 19.72%, 105.48 13.65%, and 110.65 11.00%, respectively (in comparison to model group,P 0.01). The decreased fluorescence intensities, as is certainly shown in Body 6(h), also recommended the intracellular ROS scavenge P7C3-A20 cost capability of fucoxanthin in H2O2-treated L02 cells.
