Ovarian reserve and response are associated with oocyte telomere DNA content not peripheral blood telomere DNA content

Blood leucocyte telomere DNA content predicts vascular telomere DNA content in humans with and without vascular disease.

AIMS Previous studies have suggested that reduced telomere length in circulating leucocytes in humans is associated with premature vascular disease and by implication, accelerated vascular ageing. Importantly, a link between telomere length in circulating leucocytes and the blood vessel wall has never been established. We, thus, investigated the relationship between vascular wall and circulatin...

Measurement of telomere DNA content by dot blot analysis

Telomeres play a central role in human cancer, cardiovascular aging and possibly longevity. However, present methods to measure telomere length are fraught with shortcomings that limit their use. Here, we describe a novel method to measure the relative telomere DNA content by dot blot analysis. In each dot, the DNA content is measured by a DNA stain (Dx) and the telomeric DNA content is measure...

Only Female Age, and Not Blood Type, Is Associated with Ovarian Reserve

Blood Cell Mitochondrial DNA Content and Premature Ovarian Aging

Primary ovarian insufficiency (POI) is a critical fertility defect characterized by an anticipated and silent impairment of the follicular reserve, but its pathogenesis is largely unexplained. The frequent maternal inheritance of POI together with a remarkable dependence of ovarian folliculogenesis upon mitochondrial biogenesis and bioenergetics suggested the possible involvement of a generaliz...

Tiny telomere DNA.

We describe the design, synthesis and biophysical characterization of a novel DNA construct in which a folded quadruplex structure is joined to a standard double helix. Circular dichroism, gel electrophoresis, three-dimensional UV melting and differential scanning calorimetry were all used to characterize the structure. Rigorous molecular dynamics simulations were used to build a plausible atom...
