Nanopore Direct RNA sequencing of mice hippocampal brain tissues

We tested mouse hippocampi RNA samples, using a Nanopore direct RNA-seq protocol that in addition to long poly A selected RNAs allows sequencing also of non-poly A RNAs as well as short RNAs < 200nt (including SINE B2 RNAs and other non poly A non coding RNAs). We provide here as a resource a direct RNA-sequencing dataset generated from mouse brain tissues that includes both mRNAs and non poly A or short non-coding RNAs such as SINEs.

Elevated SINE B2 RNA Adenosine to Inosine editing is consistently observed across hippocampal tissues of a mouse model of amyloid beta accumulation compared to hippocampi of wild type animals. Nanopore direct RNA sequencing supports increased RNA modification signals at the sameSINE B2 RNA regions identified by short-read Illumina sequencing in these hippocampi.
