Justine Bélik has published as a preprint the first epigenetic clock in the mangrove rivulus, and the first ever on a self-fertilizing species. She has been working on brain tissue samples from 96 individuals from Emerson Point Preserve, Florida, up to 1000 days of age. With this clock, we’re able to predict the chronological age of the fish with a mean absolute error of 28.7 days, which is quite accurate. Also, This article is the first to correlate the epigenetic clock with functional annotation in the brain, leading to new insights into the brain aging process. Congratulations Justine for this nice work and looking forward to the final publication. The preprint can be found on bioRxiv here.
