Compartmentalisation of m6A (N6-methyladenosine) methylated RNA in somatic or axonal subcellular locations is dependent on Nerve Growth Factor (NGF) state in sympathetic neurons [Axon-meRIP-seq]

Cells were then subjected to NGF starvation for 18 hours followed by 1 hour of restimulation. RNA was collected from either cell bodies (CB) or axons (Ax) from these neurons for meRIP-seq.

Here, we find a strong compartmentalisation effect, in which RNA is hypermethylated in axons in both control and restimulated conditions. We also find that a select few RNA species are hypermethylated in restimulated axons compared to control axons, suggesting a fast time-dependent function for m6A marks in these RNAs.
