Frequency of Pro475Ser Polymorphism of ADAMTS13 Gene and Its Association with ADAMTS-13 Activity in the Korean Population

چکیده
PURPOSE The in vitro study suggested that proline to serine polymorphism in codon 475 (C1423T) of the A Disintegrin and Metalloprotease with ThromboSpondin type 1 repeats-13 (ADAMTS-13) gene is related to reduced activity of ADAMTS-13. In this study, the frequency of the Pro475Ser polymorphism in Koreans was studied and plasma ADAMTS-13 activity was measured to find out whether this polymorphism contributes to decreased ADAMTS-13 activity in Koreans. PATIENTS AND METHODS The frequency of the C1423T allele of the ADAMTS13 gene was studied along with measuring plasma ADAMTS-13 activity in 250 healthy Korean individuals. RESULTS The allele frequency of C1423T polymorphism was 4%, and the median activity of CT type was 107 (69-143)%, which was lower than in controls with the CC genotype [118 (48-197)%, (p=0.021)]. CONCLUSION Therefore, the Pro475Ser polymorphism seems to be popular in the Korean population, and attenuates ADAMTS-13 plasma activity.

Background: MiRNAs are one of the most important genetic regulators that regulate more than 50 percent of the human genome. MiR-124-a-3 is a tumor suppressor miRNA which its expression dramatically reduced in prostate cancer tumor cells. Since miRNA binding to the transcript of target genes by seed sequence, any mutations and changes in this region could be effective on its performance and iden...
