MicroRNA plays a crucial role in post-transcriptional gene regulation and has recently emerged as a factor linked to aging, but the underlying regulatory mechanisms remain incompletely understood. In this study, we observed lifespan-extending effects in miR-80-deficient Caenorhabditis elegans at 20°C but not 25°C. At 20°C, miR-80 deletion leads to NLP-45 upregulation, which positively correlates to increased abu transcripts and extended lifespan. Supportively, we identified miR-80 binding regions in the 5' and 3' UTR of nlp-45. As the temperature rises to 25°C, wildtype increases miR-80 levels, but removal of miR-80 is accompanied by decreased nlp-45 expression, suggesting intervention from other temperature-sensitive mechanisms. These findings support the concept that microRNAs and neuropeptide-like proteins can form molecular regulatory networks involving downstream molecules to regulate lifespan, and such regulatory effects vary on environmental conditions. This study unveils the role of an axis of miR-80/NLP-45/UPRER components in regulating longevity, offering new insights on strategies of aging attenuation and health span prolongation.
