RNA Transcript Study Identifies Shared Ageing Patterns Across Species

A study published in Nature analyzed RNA transcripts collected from rodents, monkeys, and humans. The analyses identified recurring molecular patterns linked to ageing across the three groups. The patterns, described as hallmarks of ageing, were consistent enough that the authors suggested they could help guide future research on interventions.

Samples came from multiple tissues in each species.

The study compared transcript levels at different ages within each species and then looked for overlaps between species. Researchers reported that certain transcripts changed in similar directions and magnitudes during ageing, regardless of the organism examined.

The authors stated that these shared signatures might shorten the time needed to test candidate anti-ageing compounds. They noted that the findings provide a reference set of molecular changes that could be measured in future experiments. No specific interventions were tested in the reported work.
