Specific and redundant roles for Gli2 and Gli3 in establishing cell fate during murine hair follicle development.
Article in The EMBO journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Formation of skin epithelial appendages like hair follicles requires hedgehog (Hh) signal reception, its conduction through the primary cilium and activation of Gli transcription factors. How Hh signalling induces cell-type-specific responses through Gli transcription factors in hair follicle stem cells and their cilia-dependence remains unclear. Here, we use conditional mouse mutants to genetically dissect the roles of Gli2 and Gli3 transcription factors and cilia in the skin epithelium. Upon keratinocyte-specific depletion of Gli2, hair follicle morphogenesis is delayed whereas sebaceous gland formation is enhanced, suggesting a dual role for Gli2 during appendage development. Gli2 promotes proliferation of sebaceous gland stem cells, impacting the number and size of individual sebaceous gland lobes. While ablation of Gli3 shows no detectable phenotypes, hair follicle cell fate is blocked in Gli2/Gli3 double knockout (dKO) mice, suggesting functional compensation. Finally, loss of cilia phenocopies the depletion of Gli2 but not the Gli2/3 dKO mutants. Our study reveals compartment-specific regulation of murine skin morpohogenesis by Gli2 and cilia-independent activator functions of Gli3 in the absence of Gli2.
