Exposure to UV irradiation results in abnormal, extensive apoptosis of skin cells. This excessive cell death can promote inflammation and alter the microenvironment, increasing the risk of skin cancer. Despite extensive research, few materials are effective at simultaneously protecting against both UVA and UVB irradiation.

Understanding drought resistance mechanisms is crucial for breeding poplar species suited to arid and semi-arid regions. This study explored the drought responses of three newly developed 'Zhongxiong' series poplars using integrated transcriptomic and physiological analyses. Under drought stress, poplar leaves showed significant changes in differentially expressed genes (DEGs) linked to photosynthesis-related pathways, including photosynthesis-antenna proteins and carbon fixation, indicating impaired photosynthetic function and carbon assimilation.

Backgorund: This study aimed to explore the relationship between different types of skin cancer and factors such as sun exposure and photoprotection measures in a Greek cohort on the island of Crete.
Methods: This cross-sectional observational study was conducted in the Dermatology Department of the University Hospital in Heraklion, Crete, between January 2019 and January 2024. The study population included consecutive patients diagnosed with basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and malignant melanoma (MM), as well as healthy controls.
10(E)-Pentadecenoic Acid Inhibits Melanogenesis Partly Through Suppressing the Intracellular MITF/Tyrosinase Axis.

Melanogenesis, the biological process responsible for melanin synthesis, plays a crucial role in determining skin and hair color, photoprotection, and serving as a biomarker in various diseases. While various factors regulate melanogenesis, the role of fatty acids in this process remains underexplored. This study investigated the anti-melanogenic properties of 10(E)-pentadecenoic acid (10E-PDA) through both in silico and in vitro analyses.
