Polydatin ameliorates ovalbumin‐induced asthma in a rat model through NCOA4‐mediated ferroautophagy and ferroptosis pathway

FEBS Open Bio, EarlyView.
In this research, a rat model of asthma was created using OVA, and polydatin served as an intervention. By inhibiting ferroautophagy mediated by NCOA4 and averting ferroptosis, polydatin has been demonstrated to reduce asthma. This work presents new ideas for investigating the mechanism of polydatin's ability to alleviate asthma, in addition to ...
