Osimertinib is an irreversible, oral third-generation TKI that targets the mutation at T790M, which causes cancer cells to acquire resistance to drugs. Osimertinib could be effective in the treatment of EGFR mutations with minimal effects on the activity of wild-type EGFR. Absent in melanoma 2 (AIM2) is highly expressed in glioma cells, promoting the maturation of pro-cancer cytokines and contributing to progression of glioma. However, the secretion of pro-cancer cytokines of tumour cells has been regarded as the resistance mechanism to EGFR-TKIs, including osimertinib.

This study aimed to investigate the role of lemur tyrosine kinase 2 (LMTK2) in AD as well as its relevant mechanism. To establish an in vitro cell model, PC12 cells were challenged with 20 µmol/l Ab 25-35 for 24 h. RT-qPCR and western blot examined LMTK2 mRNA and protein expressions. With the application of CCK-8, TUNEL, iron colorimetric assay kit and DCFH-DA, the viability, apoptosis, Fe 2+ and ROS content in PC12 cells were assessed. Besides, the expressions of oxidative stress-, apoptosis-, ferroptosis- and Nrf2/ARE signalling-related proteins were evaluated with western blot. Moreover, commercial kits examined SOD, MDA and CAT contents. The results manifested that LMTK2 expression was noticeably downregulated in Ab 25-35 -treated PC12 cells. Notably, LMTK2 overexpression exhibited inhibitory effects on oxidative stress, apoptosis and ferroptosis in PC12 cells exposed to Ab 25-35 . The upregulated Nrf2, NQO1 and HO-1 expressions in LMTK2 overexpressed-PC12 cells with Ab 25-35 induction revealed that LMTK2 overexpression could activate the Nrf2/ARE signalling pathway.
