For a functional characterization of TRPM7 in lung cancer, we accessed and analyzed TRPM7 gene expression profile in early stage NSCLC dataset with the series accession number GSE19188 and consisting of large-cell carcinoma (LCC, n = 19), adenocarcinoma (ADC, n = 45), squamous cell cancer (SCC, n = 27) and normal lung tissue (n = 65) were accessed via the Gene Expression Omnibus (GEO) browser. The gene discussed is TRPM7; the disease is lung cancer.
