Keratinocytes exposed to ultraviolet A and ultraviolet B radiation induce responses in melanocytes

open access: yesPhotochemistry and Photobiology, EarlyView.
Keratinocyte‐derived soluble factors regulate melanocyte responses following UV exposure. Conditioned medium from irradiated keratinocytes enhances melanocyte mitochondrial activity, cell proliferation, and cell cycle progression while improving survival after UVA‐induced damage.

Development of a genetically encoded melanocortin sensor for high sensitivity in vivo imaging

open access: yesMolecular Metabolism
Objective: The central melanocortin system, composed of peptides derived from pro-opiomelanocortin (POMC) such as the melanocyte-stimulating hormones (α-, β-, γ-MSH) and melanocortin 4 receptors (MC4R), along with the agouti-related protein (AgRP), plays

Ribosomal S6 kinase 2-forkhead box protein O4 signaling pathway plays an essential role in melanogenesis

open access: yesScientific Reports
Although previous studies have examined the signaling pathway involved in melanogenesis through which ultraviolet (UV) or α-melanocyte-stimulating hormones (α-MSH) stimuli act as key inducers to produce melanin at the stratum basal layer of the epidermis,

Integrated Phytochemical Characterisation, Pharmacological Evaluation and Computational Investigation of Acampe papillosa Stem Extract

open access: yesAnalytical Science Advances, Volume 7, Issue 2, December 2026.
The pharmacological potential of the methanolic stem extract of Acampe papillosa is evaluated using in vivo and in silico approaches. The extract demonstrates significant anxiolytic, sedative, anti‐inflammatory, and antipyretic activities in experimental models, while molecular docking supports the observed biological effects through favorable ...

Streamlining Diagnosis of Bardet–Biedl Syndrome: New Diagnostic Algorithm With Updated Criteria

open access: yesAmerican Journal of Medical Genetics Part A, Volume 200, Issue 10, Page 2181-2198, October 2026.
ABSTRACT Considerable advances have been made in our understanding of Bardet–Biedl syndrome (BBS), particularly in its core clinical features and molecular genetics, warranting an update to the existing diagnostic criteria framework. Using a rigorous, evidence‐based, and consensus‐driven process, a multidisciplinary group of international experts and ...

Exploring the Cosmeceutical Potential of Six Malaysian Indigenous Tropical Fruit Trees: Radical Scavenging, Anti‐Tyrosinase, and Photoprotective Activities Evaluation

open access: yesChemistry &Biodiversity, Volume 23, Issue 10, October 2026.
B. macrophylla leaf ethyl acetate fractionated extract exhibits the highest TPC, very strong radical‐scavenging activities, and the highest SPF value of 28.64 ± 0.51. LC‐MS analysis identifies m‐trigallic acid, cis‐coutaric acid, and ellagic acid, which may contribute to its bioactivities. The present work highlights B.
