A Common Aging Pattern: Changes in RNA Splicing and Processing Across Human Tissues

As we age, every tissue in the body undergoes gradual molecular changes. A long-standing question in aging research is whether these changes follow common patterns across tissues or whether each tissue ages on its own. While DNA-based “epigenetic clocks” can estimate age accurately across different tissues, identifying consistent patterns in gene expression has been much more challenging. One reason for this difficulty is methodology. Most studies focus on whether genes increase or decrease their expression levels with age. However, genes do not function in isolation. They operate within complex networks, coordinating their activity with many others. Changes in these relationships may be important aspects of the aging process. To understand this, researchers from the University of São Paulo performed a study titled “A combination of differential expression and network connectivity analyses identifies a common set of RNA splicing and processing genes altered with age across human tissues.” Full blog - https://aging-us.org/2026/01/a-common-aging-pattern-changes-in-rna-splicing-and-processing-across-human-tissues/ Paper DOI - https://doi.org/10.18632/aging.206347 Corresponding author - Nadja C. de Souza-Pinto - nadja@iq.usp.br Abstract video - https://www.youtube.com/watch?v=A1slKwaSd6g Sign up for free Altmetric alerts about this article - https://aging.altmetric.com/details/email_updates?id=10.18632%2Faging.206347 Subscribe for free publication alerts from Aging - https://www.aging-us.com/subscribe-to-toc-alerts Keywords - aging, gene expression, co-expression network analysis, RNA processing To learn more about the journal, please visit https://www.Aging-US.com​​ and connect with us on social media at: Bluesky - https://bsky.app/profile/aging-us.bsky.social ResearchGate - https://www.researchgate.net/journal/Aging-1945-4589 Facebook - https://www.facebook.com/AgingUS/ X - https://twitter.com/AgingJrnl Instagram - https://www.instagram.com/agingjrnl/ YouTube - https://www.youtube.com/@Aging-US LinkedIn - https://www.linkedin.com/company/aging/ Pinterest - https://www.pinterest.com/AgingUS/ Spotify - https://open.spotify.com/show/1X4HQQgegjReaf6Mozn6Mc MEDIA@IMPACTJOURNALS.COM
