Establishment and Validation of a C57BL/6J Mouse Model for Melasma.
Article in Cell proliferation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Melasma is a recurrent and treatment-resistant hyperpigmentation disorder characterized by a complex and multifactorial pathogenesis. However, the lack of a stable and reliable animal model has hindered systematic investigations into its onset and progression. In this study, we established a melasma-like model in C57BL/6J mice by combining broadband UVB irradiation, intramuscular progesterone administration, and induced emotional stress. The affected skin areas exhibited irregular, brown hyperpigmented patches. Histopathological analysis revealed an accumulation of melanin granules in the epidermis and superficial dermis, elevated levels of tyrosinase (TYR) in both skin and plasma, systemic oxidative stress imbalance, and reduced autophagic activity in the lesional skin. Furthermore, this model displayed distinct differences from a UV-induced post-inflammatory hyperpigmentation (PIH) model. Notably, the melasma-like mice responded to tranexamic acid treatment in a manner that closely resembled clinical outcomes observed in human patients. Collectively, these findings establish a stable, reproducible, and clinically relevant mouse model of melasma, providing a valuable platform for future research into its pathogenesis and treatment.
