Detection of a single nucleotide polymorphism in the IL-6 promoter region of ancient nuclear DNA

摘要

In the current study a method was developed to examine the G/C single nucleotide polymorphism (SNP) at position -174 in the IL-6 promoter from nuclear DNA samples isolated from human skeletal remains from Manitoba, Canada, dating to as early as 3500 years ago. The IL-6 (-174) SNP was detected in three ancient samples and determined, as expected, in three out of three to be homozygous G/G. The analysis of cytokine SNPs of ancient nuclear DNA may provide novel insights into the genetic basis of autoimmune diseases and the susceptibility/resistance to infectious agents.
