PTK2 and non-small cell lung carcinoma: Liu et al. [18] found that nuclear factor-erythroid 2-like 2 (NRF2) inhibitor (brusatol) could enhance the sensitivity of NSCLC cells to cystine deprivation-induced ferroptosis depending on FOCAD-FAK signaling, and the combination of brusatol and erastin showed better therapeutic effect of NSCLC.
