Small RNA modifications in Alzheimer's disease.

ABSTRACT: Background While significant advances have been made in uncovering the aetiology of Alzheimer's disease and related dementias at the genetic level, molecular events at the epigenetic level remain largely undefined. Emerging evidence indicates that small non-coding RNAs (sncRNAs) and their associated RNA modifications are important regulators of complex physiological and pathological processes, including aging, stress responses, and epigenetic inheritance. However, whether small RNAs and their modifications are altered in dementia is not known. Methods We performed LC-MS/MS-based, high-throughput assays of small RNA modifications in post-mortem samples of the prefrontal lobe cortices of Alzheimer's disease (AD) and control individuals. We noted that some of the AD patients has co-occurring
