Another study exploring miRNA expression in MG thymomas showed elevation of miR-19b-5p in the neoplastic thymic tissue of MG patients compared to normal thymuses, as well as the ability of this miRNA to post-transcriptionally inhibit the expression of thymic stromal lymphopoietin (TSLP), which indeed was down-regulated in MG thymomas [90]. The gene discussed is TSLP; the disease is myasthenia gravis.
