Polo‐like kinases and UV‐induced skin carcinogenesis: What we know and what's next

Photochemistry and Photobiology, EarlyView.
The polo‐like kinase (PLK) family plays distinct and critical roles in the regulation of cell cycle progression, and its dysregulation has been implicated in various cancers. Ultraviolet (UV) radiation is a well‐established environmental factor in the development of skin cancer.

Apoptosis kinetics of purified and PBMC‐associated lymphocytes after photopheresis‐like 8‐methoxypsolaren/UVA treatment

Photochemistry and Photobiology, EarlyView.
Extracorporeal photopheresis (ECP) induces apoptosis in circulating immune cells, but its kinetics vary slightly depending on the cell type. We compared the progression of apoptosis in PBMCs versus highly purified T cells exposed to 8‐methoxypsoralen and ultraviolet A.

Constitutive nitric oxide synthases deficiency impairs cyclobutane pyrimidine dimer repair following solar UV exposure in cells and mice

Photochemistry and Photobiology, EarlyView.
Proposed model for the dual role of cNOS in DNA damage and repair upon UV radiation. Abstract Solar ultraviolet (sUV) radiation is a major environmental factor that induces DNA damage, promoting skin aging and carcinogenesis. The formation of cyclobutane pyrimidine dimers (CPDs) is one of the most prevalent forms of UV‐induced DNA lesions, playing a ...

Exploring natural sunscreens: UVB protection and antioxidant properties in gadusol‐rich fish roes extracts

Photochemistry and Photobiology, EarlyView.
Gadusol‐rich extracts provide effective UVB protection and antioxidant activity in HaCaT cells and C. elegans, highlighting their potential as natural photochemoprotective agents for pharmaceutical and cosmetic applications. It also demonstrates remarkable in vitro antioxidant capacity and thermal stability over time.

Alleviation of photoaging‐associated MMP upregulation, prostanoid biosynthesis, and cell cycle arrest with titanium dioxide, zinc oxide, and inorganic‐only (ZnO + TiO2) sunscreens

Photochemistry and Photobiology, EarlyView.
Inorganic sunscreens containing the UV filters titanium dioxide (TiO2) and/or zinc oxide (ZnO) alleviated various biomarkers of photoaging in human dermal fibroblasts, at a gene and protein level. The study provides novel insights that observe the impact of inorganic photoprotection through the molecular biology of skin.
