Leveraging the available expression data from TCGA and GTEX, as tumour and respectively normal control lung samples (referring as ‘Lung’ in figures), we have investigated differential expression patterns of XIST, TSIX, hnRNPu, Bcl-2, and BRAC1 in lung adenocarcinoma (LUAD) and lung squamous carcinoma (LUSC) (Supplementary Figure S1). This evidence concerns the gene TSIX and lung adenocarcinoma.
