We downloaded and analyzed the sequencing data of GSE19188 and GSE33532 datasets from R2 and found that JPX was significantly upregulated in lung adenocarcinoma tissues in comparison to normal lungs, with a fold change of 1.45 (p = 0.0001) and 1.21 (p = 0.0103), respectively (Figure 1a,b). Here, JPX is linked to lung adenocarcinoma.
