Heat Stress Promotes Fibroblast‐Derived WNT5A Secretion Through m6A Modification to Activate Melanogenesis

Advanced Science, EarlyView.
Heat stress promotes WNT5A secretion from fibroblasts via METTL3/YTHDC1‐dependent m6A methylation. Subsequently, WNT5A binds to FZD10 on melanocytes, activating β‐catenin‐driven melanogenesis. ABSTRACT As the impact of global warming continues to intensify, the effects of heat stress on the skin are becoming increasingly evident.

Greener Solvents for the Photoisomerization and Catalytic Heat Release of a Norbornadiene‐Based Molecular Solar Thermal Energy Storage System

Advanced Science, EarlyView.
A Molecular Solar Thermal (MOST) system combining a scalable norbornadiene–quadricyclane photoswitch, a biodegradable solvent, propylene carbonate, and noble and first‐row metal catalysts, is presented. Propylene carbonate boosts photoisomerization quantum yield by 25% compared to toluene, prolongs energy storage by an additional 15 days, and enables ...

GSDME deficiency leads to the aggravation of UVB-induced skin inflammation through enhancing recruitment and activation of neutrophils

Cell Death and Disease, 2022
Gasdermin E (GSDME)-mediated pyroptosis is induced in keratinocytes of UVB-challenged skin. The role of GSDME in UVB-caused skin damage remains unknown. To explore the role of GSDME in UVB-induced skin inflammation.

The response of bacterial community to UVB was significantly different between immature periphyton and mature periphyton, but not for physiological indicators

Ecotoxicology and Environmental Safety, 2022
Periphyton has important ecological functions. It can even exist in environments with strong ultraviolet radiation. However, knowledge of periphyton under ultraviolet is limited, which limits the understanding and application of periphyton in ...
