We are excited to share our new work, "Altered expression of the m6A methyltransferase METTL3 in Alzheimer's disease", which has just been published in eNeuro. Here we report a decrease in the expression of METTL3 mRNA and soluble protein in the postmortem hippocampal tissues of Alzheimer's disease (AD) patients. We also identified a striking alteration in the METLL3 protein expression, including enhanced insolubility and immunoreactivity in the AD hippocampus. Our results suggest that perturbation of m6A signalling may present a novel cellular mechanisms underpinning dysregulation of gene expression associated with AD pathophysiology. Congratulations to River and Jocelyn who led this study and to our QBI collaborators, Drs. Judith Camats-Perna and Rodrigo Medeiros.
