Sulforaphane Attenuates CD36-mediated platelet Hyperreactivity through Modulating cAMp/pKA/NOX2 Signaling in Hyperlipidemic Conditions

引用

Food Science and Human Wellness 2024年

Hyperlipidemia is a risk factor for clinically significant thrombotic events in cardiovascular diseases. platelet reactivity in hyperlipidemic conditions is enhanced when platelet scavenger receptor CD36 recognizes oxidized lipids in oxidized low-density lipoprotein (ox-LDL) particles， a process that induces atherothrombosis. Sulforaphane (SFN) is a dietary isothiocyanate enriched in cruciferous vegetables and exerts multiple biological activities. The current study sought to investigate the efficacy of SFN on platelet hyperreactivity under hyperlipidemic conditions in vitro and in vivo. Using a series of platelet functional assays in human platelets in vitro， we demonstrated that SFN attenuated ox-LDL-increased platelet aggregation and activation (surface CD62p expression). Mechanistically， studies using pharmacological inhibitors clarified that these inhibitory effects of SFN were mainly modulated by down-regulating CD36-mediated activation of Src kinases， leading to enhanced activation of cAMp/pKA signaling， and resultant inhibition of NAD phosphate oxidase 2 (NOX2)-dependent generation of reactive oxygen species (ROS). Moreover， 12-week supplementation of SFN-enriched broccoli sprout extract (BSE， 0.06% diet) in hyperlipidemic C57BL/6J mice also decreased platelet hyperreactivity. Studies using pharmacological inhibitors of CD36， pKA and NOX2 showed that the efficacy of BSE supplementation was mainly through modulating CD36-mediated the cAMp/pKA/NOX2 signaling. Thus， through modulating the cAMp/pKA/NOX2 pathway and attenuating CD36-mediated platelet hyperreactivity， SFN may play important protective roles in atherothrombosis under hyperlipidemic conditions.

Nitrate reduction capacity of the oral microbiota is impaired in periodontitis:potential implications for systemic nitric oxide availability

The reduction of nitrate to nitrite by the oral microbiota has been proposed to be important for oral health and results in nitric oxide formation that can improve cardiometabolic conditions. Studies of bacterial composition in subgingival plaque suggest that nitrate-reducing bacteria are associated with periodontal health, but the impact of periodontitis on nitrate-reducing capacity(NRC)and, therefore, nitric oxide availability has not been evaluated. The current study aimed to evaluate how periodontitis affects the NRC of the oral microbiota. First, 16S rRNA sequencing data from five different countries were analyzed, revealing that nitratereducing bacteria were significantly lower in subgingival plaque of periodontitis patients compared with healthy individuals(p ples per dataset). Secondly, subgingival plaque, saliva, and plasma samples were obtained from 42 periodontitis patients before and after periodontal treatment. The oral NRC was determined in vitro by incubating saliva with 8 mmol/L nitrate(a concentration found in saliva after nitrate-rich vegetable intake) and compared with the NRC of 15healthy individuals. Salivary NRC was found to be diminished in periodontal patients before treatment(p healthy levels 90 days post-treatment. Additionally, the subgingival levels of nitrate-reducing bacteria increased after treatment and correlated negatively with periodontitis-associated bacteria(p periodontal treatment on the baseline saliva and plasma nitrate and nitrite levels was found, indicating that differences in the NRC may only be revealed after nitrate intake. Our results suggest that an impaired NRC in periodontitis could limit dietary nitrate-derived nitric oxide levels, and the effect on systemic health should be explored in future studies.
