Strong Support
When skin cells are exposed to UVB light in a lab, they start two types of cell death: one fast kind (within a few hours) and one slower kind (after 6 hours), and both depend on a protein called ZAKα.

The ribotoxic stress response drives acute inflammation, cell death, and epidermal thickening in UV-irradiated skin in vivo
Randomized Controlled Trial
Animal
2024 Dec 19The study shows that UVB light causes skin cell damage through a stress pathway involving ZAKα, which triggers two types of cell death—one through p38 and another through JNK—just like the claim says.
