Abstract

Background Vitamin D is a potent inhibitor of the proinflammatory response and thereby diminishes turnover of leukocytes. Leukocyte telomere length (LTL) is a predictor of aging-related disease and decreases with each cell cycle and increased inflammation.Objective The objective of the study was to examine whether vitamin D concentrations would attenuate the rate of telomere attrition in leukocytes, such that higher vitamin D concentrations would be associated with longer LTL.Design Serum vitamin D concentrations were measured in 2160 women aged 18-79 y (mean age: 49.4) from a large population-based cohort of twins. LTL was measured by using the Southern blot method.Results Age was negatively correlated with LTL (r = -0.40, P < 0.0001). Serum vitamin D concentrations were positively associated with LTL (r = 0.07, P = 0.0010), and this relation persisted after adjustment for age (r = 0.09, P < 0.0001) and other covariates (age, season of vitamin D measurement, menopausal status, use of hormone replacement therapy, and physical activity; P for trend across tertiles = 0.003). The difference in LTL between the highest and lowest tertiles of vitamin D was 107 base pairs (P = 0.0009), which is equivalent to 5.0 y of telomeric aging. This difference was further accentuated by increased concentrations of C-reactive protein, which is a measure of systemic inflammation.Conclusion Our findings suggest that higher vitamin D concentrations, which are easily modifiable through nutritional supplementation, are associated with longer LTL, which underscores the potentially beneficial effects of this hormone on aging and age-related diseases.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Adipokine secretion profiles differ between subcutaneous and abdominal adipose tissues.

    “In addition, the profile of adipokines produced is dissimilar between the subcutaneous and abdominal adipose tissues.”
  • IL-6 and TNF-a appear to be synthesised equally by different adipose tissue sites.

    “In contrast to such distributions, there are reports that IL-6 and TNF-a seem to be equally synthesised by the different sites (28,36,53 -59) .”
  • Leptin is preferentially expressed and secreted by subcutaneous adipose tissue, while adiponectin, visfatin, omentin, resistin, PAI-1, IL-8, IL-7, IL-1a, MCP-1, TGF-b, growth-related oncogene, CCL5 and MIP-1b are expressed more in abdominal fat.

    “Thus, leptin is preferentially expressed and secreted by subcutaneous adipose tissue (52) , while the expression of adiponectin, visfatin, omentin, resistin, PAI-1, IL-8, IL-7, IL-1a, MCP-1, TGF-b, growth-related oncogena, CCL5 and MIP-1b is higher in abdominal fat.”

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.
