Abstract

Background Several single nucleotide polymorphisms have been proposed as potential predictors of the development of age-related diseases.Objective To explore whether Tumor Necrosis Factor Alpha (TNFA) gene variants were associated with inflammatory status, thus facilitating the rate of telomere shortening and its relation to cellular aging in a population with established cardiovascular disease from the CORDIOPREV study (NCT00924937).Materials and methods SNPs (rs1800629 and rs1799964) located at the TNFA gene were genotyped by OpenArray platform in 840 subjects with established cardiovascular disease. Relative telomere length was determined by real time PCR and plasma levels of C-reactive protein by ELISA. In a subgroup of 90 subjects, the gene expression profiles of TNFA, IKKβ, p47phox, p40phox, p22phox and gp91phox were determined by qRT-PCR.Results GG subjects for the SNP rs1800629 at the TNFA gene showed shorter relative telomere length and higher plasma levels of hs-CRP than A-allele subjects (p<0.05). Consistent with these findings, the expression of pro-inflammatory (TNFA) and pro-oxidant (p47phox and the gp91phox) genes was higher in GG subjects than A allele subjects (p<0.05).Conclusion Subjects carrying the GG genotype for the SNP rs1800629 at the TNFA gene show a greater activation of the proinflammatory status than A-allele carriers, which is related to ROS formation. These ROS could induce DNA damage especially in the telomeric sequence, by decreasing the telomere length and inducing cellular aging. This effect may also increase the risk of the development of age-related diseases.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
