Generally, the top 10 co-cited references focused on reviews (three reviews were published in 2017 and 2016), mechanisms (include targets and genes, such as GPX4, glutamine, GSH, iron-carrier protein transferrin, p53, SLC7A11, ACSL4, system xc−, PUFAs, lipoxygenase, etc.), and related diseases of ferroptosis (such as cancers, acute renal failure, ischemia/reperfusion-induced hepatic and heart damage etc.), all these were the foundations of ferroptosis research. Here, SLC7A11 is linked to cancer.
