Multiple molecular pathways to longevity with opposing gene expression programs defining distinct aging strategies in Caenorhabditis elegans.

Multiple distinct gene expression programs define at least three different longevity strategies in Caenorhabditis elegans, with some pathways modulating genes in opposing directions.

• Why it matters: Understanding diverse aging mechanisms is crucial for developing targeted therapies to promote healthy aging and combat age-related neurodegenerative diseases, which are linked to the aging process.
• What they did: RNA sequencing was performed on nine long-lived C. elegans mutants representing seven different lifespan-extending pathways, revealing common and distinct gene expression patterns across mutants.
• The result: Identifying 258 genes consistently modulated in long-lived mutants, some of which individually extend lifespan when knocked down or overexpressed, highlights potential targets for aging interventions.
