Searching for Jouvence SnoRNA in the Horse Genome

In humans, various pathologies have been associated with snoRNAs. Others have shown that the expression of a non-canonical snoRNA Jouvence is involved in lifespan determination in relation to gut homeostasis. As snoRNAs are evolutionary conserved, both structurally and functionally, a jouvence orthologue has been identified in humans. This study aimed to locate the Jouvence snoRNA in the horse genome. Using our previous snoRNA data in ageing equine cartilage along with equine genome data we identified a putative equine Jouvence snoRNA gene. ECABCGRLG0000000730 was the primary candidate horse Jouvence snoRNA. The expression of equine Jouvence snoRNA was increased in ageing equine cartilage.
