Of note, the NEFM expression was up-regulated in both MG and non-MG thymomas compared to hyperplastic MG and control thymuses (Figure 4a), with no significant difference observed between the two thymoma groups, as well as between thymomas from corticosteroid-naïve and -treated MG patients (Figure 4c). The gene discussed is NEFM; the disease is thymoma.
