CYLD mutations skin tumors CYLD cutaneous syndrome topical aspirin nuclear factor KB pathway

Studysummary This study observed that patients with CYLD mutations frequently experienced severe, painful tumors beyond the head and neck, impacting their quality of life, with hormonal factors possibly contributing to tumor development. Our plain-language summary of this paper — not a Tressless recommendation.

In 2009, researchers studied 34 individuals from two families with CYLD mutations to understand the clinical features of related skin tumors. They found significant variability in symptoms and tumor locations, with an average onset age of 16. The study revealed that CYLD mutations lead to a range of skin tumors, with 50 different mutations identified, mostly at the gene's carboxyl terminus. This variability complicates genetic counseling and prognostication. The term "CYLD cutaneous syndrome" was proposed to encompass the range of associated clinical diagnoses. The study also noted the limited effectiveness of topical aspirin and the potential for treatments targeting the nuclear factor KB pathway, emphasizing the need for further research in this area.

research Premature Senescence of Balding Dermal Papilla Cells In Vitro Is Associated With p16INK4a Expression

141 citations , November 2007 in “Journal of Investigative Dermatology”

This study found that balding dermal papilla cells show premature senescence and altered expression of stress and DNA damage markers, suggesting sensitivity to environmental stress in androgenetic alopecia.

research Cylindroma as a Tumor of Hair Follicle Origin

57 citations , February 2006 in “Journal of Investigative Dermatology”

Cylindromas likely originate from hair follicle stem cells, not sweat glands.

research Characterization and Isolation of Stem Cell-Enriched Human Hair Follicle Bulge Cells

550 citations , December 2005 in “The Journal of clinical investigation/The journal of clinical investigation”

This study found that bulge cells marked by CD200+ in human hair follicles show high colony-forming efficiency, suggesting successful enrichment of keratinocyte stem cells.
