In addition to this, the use of LaFeO3 perovskite nanocrystals–enzymes, which present enzyme-mimicking activities, including oxidase, peroxidase, GPx, and CAT activities, reverse the hypoxic microenvironment and the depletion of endogenous glutathione and promote the continuous production of ROS and the process of pyroptosis, presenting an alternative in the treatment of BC [186]. Here, CAT is linked to breast cancer.
