6-gingerol is a monophenolic compound derived from rhizome of Zingiber officinale Roscoe [222], which can promote ferroptosis of lung cancer in vitro and in vivo by inhibiting the expression of autophagy-related protein ubiquitin-specific peptidase 14 (USP14) and regulating the downstream of autophagy-dependent ferroptosis [223]. Here, USP14 is linked to lung cancer.
