Data analyzed using the GEPIA2 web server indicate that while ERK3 mRNA (as MAPK6 gene expression) is increased in tumor samples, reaching statistical significance in lung squamous cell carcinoma, DGKζ (as DGKZ gene expression) has a non-statistically significant decrease in the same samples (Supplementary Figures S3A, S3B) (Tang et al., 2017). The gene discussed is MAPK6; the disease is squamous cell lung carcinoma.
