Simultaneously, ROS oxidize the regulatory domain of PTP1B, inhibiting leptin receptor signal transduction [344], and activate the hepatic IKK/NF-B pathway, inducing lipid deposition [348]
Nevertheless, these potential effects require further research validation, and no definitive clinical application protocols have been established to date
