Matrilysin-2 (matrix metalloproteinase (MMP)-26) is a small protein of the MMP family expressed in some epithelial carcinomas and normal tissues. We studied its role in benign skin disorders characterized by epithelial proliferation, in wound repair, skin cancer, and regulation in keratinocyte (KC) cultures. MMP-26 is expressed by laminin-5-positive KC in(More)
The PSORS1 locus in the major histocompatibility complex region is the major genetic determinant for psoriasis vulgaris. Within the PSORS1 region reside at least three potential candidate genes for psoriasis susceptibility. Specific allelic variants of the genes HLA-Cw*6, HCR*WWCC, and CDSN*5 are strongly associated with psoriasis vulgaris and are in strong(More)
The major susceptibility locus for psoriasis, PSORS1, resides on chromosome 6p and includes the candidate genes HLA-C, HCR, and CDSN. Based on a nationwide collection of psoriasis patients and genotyping for the PSORS1 susceptibility haplotype, we selected for a genome scan nine families who do not show association with PSORS1 to more easily detect minor(More)
The PSORS1 locus is the consistently replicated genetic risk factor for psoriasis. Clinical associations with the main marker allele of PSORS1, HLA-Cw6, have been addressed in a number of studies, but clinical associations have not been used as a way to distinguish the effects of the neighbouring candidate genes in PSORS1. Our results show that HLA-Cw6 and(More)
Epilysin (MMP-28) is the newest member of the matrix metalloproteinase enzyme family. Several members of this enzyme family have been associated with various aspects of wound repair and cancer invasion. The aim of this study was to characterize in different types of wounds, skin cancers, and keratinocyte cultures factors that contribute to epilysin(More)
PSORS1, near HLA-C, is the major genetic determinant of psoriasis. We present genetic and structural evidence suggesting a major role for the HCR gene at the PSORS1 locus. Genotyping of 419 families from six populations revealed that coding single-nucleotide polymorphisms of HCR formed a conserved allele HCR*WWCC that associated highly significantly with(More)
MMP-19 (also designated RASI) is a recently discovered member of a large family of zinc-dependent proteolytic enzymes, most of which have been implicated in cancer growth and metastasis. It differs from the others by its chromosomal location and structure and is expressed by endothelial and vascular smooth muscle cells in vivo. Our aim was to study the(More)
In skin biology, matrix metalloproteinases (MMPs) have been implicated in inflammatory matrix remodeling, neovascularization, wound healing and malignant transformation. Psoriasis is histologically characterized by keratinocyte hyperproliferation, infiltration of inflammatory cells, neoangiogenesis and production of cytokines, such as TNF-alpha, IL-1beta,(More)
The CCHCR1 gene (Coiled-Coil alpha-Helical Rod protein 1) within the major psoriasis susceptibility locus PSORS1 is a plausible candidate gene for the risk effect. We have previously generated transgenic mice overexpressing either the psoriasis-associated risk allele CCHCR1*WWCC or the normal allele of CCHCR1. All transgenic CCHCR1 mice appeared(More)
