Researchers at the Max Planck Institute for Biology of Aging have discovered that manipulating the transcription factor TFEB in worms can induce a senescent-like state, closely resembling the aging processes observed in mammals.

This study highlights the critical role of TFEB in regulating gene expression in response to nutrient availability, as well as its function in preventing cellular senescence during periods of nutrient scarcity.

Under normal conditions, worms exhibit the ability to regenerate and rejuvenate after fasting; however, in the absence of TFEB, they enter a senescent-like state marked by DNA damage and inflammation.

This senescent-like condition in worms is characterized by several features, including DNA damage, nucleolar enlargement, increased mitochondrial reactive oxygen species (ROS), and the activation of inflammatory signals, mirroring the aging process in mammals.

Genetic screens conducted in this study identified crucial growth factors, such as insulin and transforming growth factor beta (TGFbeta), which are disrupted when TFEB is absent.

The findings from this research provide a novel model for exploring senescence and may pave the way for new treatments targeting age-related diseases and cancer dormancy.

The researchers aim to leverage their findings to investigate potential therapies that specifically target senescent cells, particularly in the context of aging and cancer.

Additionally, the TFEB-TGFbeta signaling axis plays a significant role in cancer biology, particularly in the diapause state where cancer cells enter dormancy to survive chemotherapy.

This groundbreaking research was published in the journal Nature Aging on June 30, 2025, and offers a new perspective on the mechanisms and effects of senescence at an organismal level.

Future research will focus on utilizing this worm model to develop innovative treatments for age-related diseases and to further understand cancer dormancy.
