Transcriptome changes associated with targeting mTORC2 in lung squamous cell carcinoma

GSE269711 Homo sapiens Expression profiling by high throughput sequencing 6 samples Submitted 2024/10/31 Platform GPL28038
Summary
Lung squamous cell carcinoma (LUSC) represents 30% of NSCLC and is associated with high mortality and a lack of therapies. Targeted therapies for lung adenocarcinoma (LUAD) improve overall survival, but such advances have not been made for treatment of LUSC irrespective of frequent molecular abnormalities. Immune checkpoint inhibitor therapies have achieved some success in LUSC patients. However, most patients do not respond adequately to such treatment, thereby patients are left with fewer specific treatment options. Exploring vulnerabilities in NSCLC, we showed that a high percentage of LUSC patients bear genetic alterations in the PI3K-mTOR-AKT signaling pathway. Loss of function of mTORC2 in LUSC cells inhibits glycolysis and lactate secretion in cultured cells and tumor growth in vivo. The goal of this study was to investigate how targeting mTORC2 impacts LUSC and the tumor microenvironment, which can be harness for therapeutic options.
