Capsaicin induces ferroptosis of NSCLC by regulating SLC7A11/GPX4 signaling in vitro.

ABSTRACT: NSCLC is the first cause of cancer-related deaths in China and threatens life expectancy of the people. Novel drugs and treatment strategies are urgently required. Capsaicin is noticed as a potential new drug for lots of tumors due to its anti-proliferative effect on cancer cells. Our study evaluated the roles of capsaicin in NSCLC cells (A549 and NCI-H23) and further explored its underlying mechanisms. Effect of capsaicin treatment on cell viability was determined by MTT assay and IC50 values for A549 and NCI-H23 cells were ascertained. The iron kit detected the total iron levels and the ferric divalent ions levels in A549 and NCI-H23 cells. GSH kit was used to detect the expression of GSH in A549 and NCI-H23 cells. Additionally, mRNA and protein levels of SLC7A11 and GPX4 were analyzed b
