In the context of glioma, neuron-derived exosomal miR-200c-3p was shown to reduce the levels of the m6A writer ZC3H13 in microglia, impairing the methylation of dual specificity phosphatase 9 (DUSP9) mRNA, activating the p-ERK pathway, and ultimately inducing microglial M2 polarization [62]. The gene discussed is DUSP9; the disease is glioma.
