Analysis of the SMURF2 gene expression in the http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE21933 dataset (gene expression profiles of tumor and paired normal lung tissues from primary NSCLC patients in Taiwan) from the GEO database showed that SMURF2 expression was upregulated in NSCLC (Fig. 1C). Here, SMURF2 is linked to non-small cell lung carcinoma.
