Studysummary This review discusses the diverse roles of the TRPS1 gene in regulating cartilage, kidney, and hair follicle development, highlighting its functions and interactions, but provides no new experimental results. Our plain-language summary of this paper — not a Tressless recommendation.

The review discussed the role of the TRPS1 gene, which encodes a GATA-type transcription factor with nine zinc-finger motifs, in the development and differentiation of bone, kidney, and hair follicles. Mutations in TRPS1 were linked to Tricho-rhino-phalangeal syndrome, affecting skeletal development. Studies using TRPS1Δgt and Trps1-deficient mice revealed that TRPS1 played a crucial role in cartilage by regulating chondrocyte differentiation, proliferation, and apoptosis. In kidney development, TRPS1 functioned downstream of BMP7, influencing nephron formation and suppressing renal fibrosis by decreasing Arkadia expression. In hair follicles, TRPS1 was expressed in dermal papillae and mesenchymal cells, with its loss significantly impacting hair follicle development. The review highlighted the diverse functions of TRPS1 in these tissues.

research Dynamic Expression of the Zinc-Finger Transcription Factor Trps1 During Hair Follicle Morphogenesis and Cycling

46 citations , November 2007 in “Gene Expression Patterns”

This study observed that Trps1 gene expression in mice is precisely regulated in skin development, particularly during hair follicle morphogenesis, with distinct localization patterns in different cell types.

research Molecular Mechanisms Regulating Hair Follicle Development

854 citations , February 2002 in “The journal of investigative dermatology/Journal of investigative dermatology”

This review summarizes recent advances in understanding the molecular mechanisms of hair follicle formation and discusses potential future clinical applications for treating hair loss and skin tumors, but it reports no new clinical results.

research Principles of Hair Cycle Control

109 citations , December 1998 in “The Journal of Dermatology”

This review discusses the hair follicle cycle's complex regulation and highlights the potential for targeting catagen control in future therapies without presenting new experimental data.

research The Secret Life of the Hair Follicle

745 citations , February 1992 in “Trends in genetics”

This article describes the potential role of various growth factors and molecules in regulating mammalian hair follicle development but does not present new experimental results.

research Dermal-Epidermal Interactions in Hair Follicle Development and Cycling

65 citations , October 1988 in “Clinics in dermatology”

This study found that dermal papilla cells may play a critical role in hair follicle development and cycling by promoting epidermal proliferation and potentially mediating systemic factors that influence follicle behavior.
