Matrix metalloproteinase-14 and secreted frizzled-related protein 4 (near a polymorphism recently associated with Dupuytren's disease) were significantly up-regulated in nodules.
As a proof of principle, we demonstrated correlation of the high-risk genotype at the statistically most strongly associated variant with decreased secretion of the soluble WNT-antagonist SFRP4, in surgical specimen-derived DD myofibroblasts.
Fibroblasts harvested from Dupuytren's disease (DD) and carpal tunnel (CT) tissues were cultured in the presence or absence of TGF-β1 (10 ng/ml) and/or PFD (800 μg/ml).
In this study, we tested for an association between Dupuytren's disease (DD) and a novel insertion polymorphism within the 5'-untranslated region (5'-UTR), of the TGFbeta(2) gene.
Vitamin D deficiency may stimulate fibroblasts in Dupuytren's disease via mitochondrial increased reactive oxygen species through upregulating transforming growth factor-β1.
HLA-DRB1*15 phenotype frequency was higher in DD positive Caucasoids (37.3%) when compared with control data (20.9%) (corrected P=0.029): we conclude that in Caucasoids of European origin, HLA-DRB1*15 is associated with risk of developing DD.
Then, among the genomic variations observed in DD, alterations in the copy number of genes in chromosomal regions 10q22, 16p12.1 and 17p12, associations with the HLA-DRB1*15 allele and a mutation in the rRNA 16s identified in forms with a matrilinear heredity, were reported.
Matrix metalloproteinase-14 and secreted frizzled-related protein 4 (near a polymorphism recently associated with Dupuytren's disease) were significantly up-regulated in nodules.
