In this study, we found that MAEL mRNA was expressed at higher levels in gastric cancer, glioblastoma, invasive breast cancer and lung adenocarcinoma than in their corresponding normal tissues (fold change ≥2, p-value < 0.05) by online analysis of transcriptomic datasets from cancer patients on the Oncomine platform. The gene discussed is MAEL; the disease is invasive breast carcinoma.
