Ultraviolet light-induced collagen degradation inhibits melanoma invasion [PDF]
Nature Communications, 2021 Ultraviolet radiation (UVR) increases melanoma incidence. Here, the authors report that UVR-damaged dermal fibroblasts upregulate MMP1 to degrade collagen which inhibits melanoma invasion and that aged primary melanomas in skin with degraded collagen ...

Light-induced degradation of rhodamine B by tellurium quantum dots [PDF]
Water Science and Technology, 2021 Tellurium quantum dots (Te QDs) were prepared using bulk tellurium as the precursor. Te QDs can be a highly active photocatalyst for boosting the photocatalytic degradation of rhodamine B (RhB) under visible light irradiation.

Light-induced Degradation in Multicrystalline Silicon: The Role of Copper
Energy Procedia, 2016 AbstractIn this contribution, we provide an insight into the light-induced degradation of multicrystalline (mc-) silicon caused by copper contamination. Particularly we analyze the degradation kinetics of intentionally contaminated B- and Ga-doped mc-Si through spatially resolved photoluminescence (PL) imaging.

Light-Induced Dynamic Change of Phytochrome B and Cryptochrome 1 Stabilizes SINATs in Arabidopsis
Frontiers in Plant Science, 2021 Ubiquitin-dependent protein degradation plays an important role in many plant developmental processes. We previously identified a class of SINA RING-type E3 ligases of Arabidopsis thaliana (SINATs), whose protein levels decrease in the dark and increase ...
