Searching for Jouvence SnoRNA in the Horse Genome
Abstract
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.

Research summary
The paper is relevant to longevity research as it investigates the role of a snoRNA associated with lifespan determination and gut homeostasis, which are important factors in aging. However, the study primarily focuses on identifying a candidate snoRNA in the horse genome and its expression in aging equine cartilage, which represents a solid but limited contribution to the field. The findings may provide insights into snoRNA functions in aging but do not present groundbreaking advancements or solutions to the root causes of aging.
