TIIVISTELMÄ( Suomenosta)Abstract
- Idiopaattisessa keuhkofibroosissa (IPF) on pahenevaa hengenahdistusta ja keuhkojen toiminnallista huononemaa, keuhkojen rakenneosissa tapahtuvien muutoksien takia, esim. epiteliaaliset mesenkymaaliset solut myös muuntuvat.
- ADAM33 on disintegriini ja metalloproteaasi domaanin sisältävä valkuaisaine, joka saattaa korreloida keuhkofibroosiin vaikuttamalla angiogeneesiä ja keuhkojen muuntumisia. Sentakia tutkijat halusivat arvioida ADAM33 SNP yksittäisten nukelotidien polymorfian ja idiopaattisen keuhkofibroosin riskin.
BACKGROUND: Idiopathic pulmonary fibrosis (IPF) is characterized by progressive dyspnea and worsening lung function due to remodeling of the lung, including epithelial mesenchymal transition. ADAM33 is a disintegrin and metalloprotease domain-containing protein, which may be related to lung fibrosis by exerting angiogenesis and remodeling of the lung. Thus, we evaluated the association of single-nucleotide polymorphisms (SNPs) of ADAM33 with the risk of IPF.
He tutkivat 237 IPF -potilaan ja 183 terveen henkilön geenipolymorfian ADAM33 geenin suhteen, He tutkivat polymorfiat ja haplotyypit analysoiden IPF riskin statistisin keinoin iän, sukupuolen ja tupakanpolttotavat huomioon ottaen.
METHODS: A total of 237 patients with IPF and 183 healthy subjects participated in the present study. Nine polymorphisms were selected. Genotyping was performed by single-base extension. Polymorphisms and haplotypes were analyzed for associations with the risk of IPF using multiple logistic regression models controlling for age, gender, and smoking status as covariates.
RESULTS: All SNPs were in Hardy-Weinberg equilibrium. The minor allele frequency (MAF) of rs628977G>A in intron 21 was significantly lower in subjects with surgical IPF than in normal controls in the recessive model [33.2 vs. 38.0 %, p = 0.02, OR = 0.40 (0.19-0.84)]. When the subjects with clinical IPF were included, the difference in MAF persisted with a p value of 0.03 [OR = 0.50 (0.27-0.94)].
Yhteenveto: Havaittin marginaallista assosioitumista idiopaattisen keuhkofibroosin alentuneeseen riskiin resessiivisessa mallissa ADAM33 rs628977G>A
CONCLUSIONS: ADAM33 rs628977G>A was marginally associated with a decreased risk of IPF in a recessive model.

1,25-(OH)(2)D(3) has a direct inhibitory effect on passively sensitized HASMCs in vitro, including the inhibition of cell proliferation and the expressions of MMP-9 and ADAM33, which maybe associated with the beneficial role of 1,25-(OH)(2)D(3) in the prevention and therapy of asthmatic airway remodeling.
