Researchers subjected pregnant mice several protocols that mimic jet lag and evaluated the effect on the subsequent offspring. Along with reduced bone strength and muscle mass, the authors identified hypermethylation of the miR17-92 micro RNA gene cluster and differential methylation within the circadian clock gene.
Methylation was determined using the MeD-seq protocol (Boers et al. 2018). With MeD-seq, PippinHT was used to isolate 32 bp insert sequencing libraries. MeD-seq uses the restriction enzyme LpnPI which cuts at methylation sites but is blocked by fragments smaller than 32 bp.
