New Tardigrade Species Reveals Mechanisms of Radiation Resistance

Researchers discover how Hypsibius henanensis withstands extreme radiation through unique genetic adaptations.

Scientists identified a new tardigrade species, Hypsibius henanensis, that offers insights into its remarkable radiation tolerance.
The study found that 285 stress-related genes are upregulated in response to radiation exposure in these tardigrades.
Key mechanisms for radiotolerance include the DOPA dioxygenase 1 gene, which produces protective betalain pigments.
Tardigrade-specific protein TDP1 aids in rapid DNA repair, while BCS1 shields cells from mitochondrial radiation damage.
These findings could inspire advancements in human health and disease prevention by mimicking tardigrade resilience.
