Gene expression profiling in pachyonychia congenita skin

Development of skin-humanized mouse models of pachyonychia congenita.

Molecular characterization and assessment of therapeutic outcomes for inherited cutaneous disorders requires faithful preclinical models. In this study we report the establishment of two different skin-humanized pachyonychia congenita (PC) model systems, based on permanent engraftment of bioengineered skin equivalents generated from patient skin cells onto immunodeficient mice. Using keratinocy...

Therapeutic siRNAs for dominant genetic skin disorders including pachyonychia congenita.

The field of science and medicine has experienced a flood of data and technology associated with the human genome project. Over 10,000 human diseases have been genetically defined, but little progress has been made with respect to the clinical application of this knowledge. A notable exception to this exists for pachyonychia congenita (PC), a rare, dominant-negative keratin disorder. The establ...

Treatment of pachyonychia congenita.

There are currently no specific treatments for pachyonychia congenita (PC). Available treatments generally are directed at specific manifestations of the disorder, and an effective treatment plan must recognize that different patients are more or less troubled by different manifestations of the disease. Treatment for all aspects of PC has been less than completely satisfactory. Very few studies...

Pachyonychia Congenita in a Toddler

Pachyonychia Congenita-Associated Alopecia

A 5-year-old female, known case of pachyonychia congenita, presented with diffuse hair loss; remaining hairs were easily plucked kinky hairs. Hair samples from patient were investigated using a light microscope. The hairs of the patients were mainly anagen hairs and unlike normal plucked anagen hairs, showed keratinization and cornification of their hair bulbs. No specific hair shaft abnormalit...
