Embryos showed exclusive paternal expression of the SNRPN gene at day 17. Allele specific transcript
analysis at day 40 (liver, muscle, brain, heart and placenta) showed exclusive paternal expression
except in heart (3%) and placenta (7%), demonstrating SNRPN imprinting is maintained after
implantation in cattle fetal tissues and placenta (Suzuki J Jr et al, 2009).
O'Doherty AM et al (2011) found bisulphite
clones harbouring both fully methylated and fully unmethylated sequences consistent with
