TLDR LEF1 interacts with Vitamin D Receptor, affecting hair follicle regeneration and this could be linked to hair loss conditions.
The document from May 1, 2011, details a study on the interaction between the Vitamin D Receptor (VDR) and Lymphoid Enhancer-binding Factor-1 (LEF1) in keratinocytes. The study discovered that VDR interacts with the DNA-binding domain of LEF1 independently of β-catenin, which is essential for normal Wnt signaling, a pathway important for hair follicle regeneration. Mutations in the VDR that disrupt this interaction impair the VDR's ability to enhance Wnt signaling, which could have implications for hair loss conditions like alopecia totalis. The research provides insights into the molecular mechanisms of VDR in skin and hair follicle biology, particularly its role in the regulation of Wnt and Hedgehog signaling pathways. The study was based on cellular and molecular experiments and did not involve human subjects.
