A class of flavanone was found to improve melanogenesis in B16F10 mouse melanoma cell line, but little is known about its target. Herein we described the synthesis and bioevaluation of sixteen 3',4',7-trihydroxyflavanone analogues and further synthesized a novel fluorescent flavanone-BODIPY, which could improve melanogenesis in B16F10 cell line by selectively binding to its endoplasmic reticulum. The fluorescent flavanone-BODIPY was proved to be a valuable probe for studying the localization of intracellular flavanone on living cells.

Alopecia universalis (AU) is a severe form of alopecia areata characterized by the complete loss of scalp and body hair. While Janus kinase (JAK) inhibitors like baricitinib have shown promise in promoting hair regrowth in severe cases of AU, unexpected side effects, such as hair depigmentation, have not been widely reported. We present the case of a young male with AU who experienced progressive and extensive whitening of his scalp and body hair following treatment with baricitinib.

The aim of this study was to investigate how ultraviolet B (UVB) light regulates AP-1 expression via the β2-adrenergic receptor (β2-AR) in epidermal keratinocytes, which in turn regulates melanin synthesis in melanocytes, thereby modulating downstream melanin production in skin hair follicles and altering mouse skin color. We established a UV-irradiated mouse model to investigate the effects of UV radiation on changes in skin color. By measuring changes in the expression of genes related to cutaneous sympathetic nerves, norepinephrine synthesis and melanin synthesis, we investigated the relationship between β2-AR expression and cutaneous melanogenesis and determined the localization of β2-AR in cells.

, a salt-tolerant plant, has demonstrated antioxidant effects, the ability to prevent prostate enlargement, antifungal properties, and skin moisturizing benefits. This study aimed to explore the anti-melanogenic potential of the 70% ethanol extract of (TME) along with its ethyl acetate (TME-EA) and water (TME-A) fractions. TME (10-200 µg/mL), TME-EA (1-15 µg/mL), and TME-A (100-1000 µg/mL) were prepared and applied to B16F10 cells with or without α-MSH for 72 h.

This study investigated the protective effects of a ceramides derivates from the peach (PF3) on photoaging by UV-irradiated hairless mice. Mice were randomly divided into seven groups: AIN93G without UVB exposure (normal control, NC), AIN93G with UVB exposure (control, C), AIN93G supplemented 100 mg/kg body weight (BW) of L-ascorbic acid with UVB exposure (AA), AIN93G supplemented 100 mg/kg BW of arbutin with UVB exposure (Arbutin), AIN93G supplemented 10 mg/kg BW of PF3 with UVB exposure (10PF3), AIN93G supplemented 20 mg/kg BW of PF3 with UVB exposure (20PF3), and AIN93G supplemented 40 mg/kg BW of PF3 with UVB exposure (40PF3). The study examined the impact of PF3 on skin hydration, wrinkle formation, and melanogenesis using enzyme-linked immunosorbent assay (ELISA), real-time polymerase chain reaction (real-time PCR), and Western blot analysis.

Despite identifying genes regulating the coat colour in Western pig breeds, the genetic basis of the coat colour in Chinese indigenous pigs is still not understood due to the diversity of indigenous breeds and their genetic differences from exotic pigs. In this study, 215 Wuzhishan pigs with three coat colour patterns (white, black, and black-back/white-belly) were used to conduct a genome-wide association analysis. We found that genes responsible for the coat colour in the Wuzhishan breed are located on chromosome 8.
