Patients and control subjects were from the Han population in northern China. Enzyme- linked immunosorbent assay analysis revealed increased levels of serum pregnancy-associated plasma protein-A （PAPP-A） in ischemic cerebrovascular disease patients compared with healthy controls. In addition, the patients exhibited greater frequency of genotype CC and C alleles in a missense A/C （Tyr/Ser） polymorphism （dbSNP： rs7020782） of exon 14 in the PAPP-A gene. Multiple-factor logistic regression analysis on correction of age, gender, history of smoking, hypertension, diabetes mellitus, hypercholesteremia, and ischemic stroke family history showed that the risk for ischemic cerebrovascular disease in the population without the A allele at the A/C genetic locus in exon 14 of the PAPP-A was 2-folds greater than the population expressing the A allele. These experimental findings suggested that ischemic cerebrovascular disease correlated with the C allele in exon 14 of PAPP-A. In addition, the A allele is likely a protective gene; individuals carrying the A allele were less prone to ischemic cerebrovascular disease compared with individuals without the A allele.展开更多

Atherosclerotic arteries obtained at autopsy from patients who died suddenly of cardiac causes indicate that pregnancyassociated plasma protein-A （ PAPP-A ） was abundantly expressed in plaque cells and in the extracellular matrix of ruptured and eroded unstable plaques, but not in stable plaques. Here we examined circulating PAPP-A levels in patients with ACS in order to evaluate its potential use in identifying vulnerable patients.展开更多
