چکیده

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 atomic-level structural model of the DNA construct. This novel DNA construct provides a model for the duplex-quadruplex junction region at the end of chromosomal DNA and offers a system for the study of structure-selective ligand binding.

Comparison of Sperm Telomere Length between Two Sperm Selection Procedures: Density Gradient Centrifugation and Zeta Potential

Background: Telomeres are particular sequences of DNA located at the end of the eukaryotic chromosomes that are essential for genome integrity. Telomere length in spermatozoa differs among males, as well as spermatozoa. Also, decreased telomere length in spermatozoa of infertile men is associated with the reduction of fertility potential and embryo quality. Density gradient centrifugation (DGC)...

Is Telomere Length a Biomarker of Adaptive Response? Controversial Findings of NASA and Residents of High Background Radiation Areas

Telomere length and stability is a biomarker of aging, stress, and cancer. Shortening of telomeres and high level of DNA damages are known to be associated with aging. Telomere shortening normally occurs during cell division in most cells and when telomeres reach a critically short length, DNA damage signaling and cellular senescence can be triggered. The induction of an adaptive response by sp...

Segmenting telomeres and chromosomes in cells

The very end of every chromosome is a region called the telomere. Telomeres are nucleo-protein complexes containing specific DNA repeat sequences whose lengths are strongly believed to give indications to aging and tumor progression. In order to study the role these repeat sequences play in the cell, we developed a fluorescence microscopy imaging system and associated image analysis methods to ...

Is telomere erosion a mechanism of species extinction?

According to the fossil record, 99.9% of all species that have ever lived on Earth have disappeared. However, only about 4% died out during the five mass extinction events, whereas it seems that the majority of species vanished without any signs of significant earthbound or extraterrestrial physical threats. Clearly, biological extinction mechanisms are by far the most important, but they are s...

Telomeric circles are abundant in the stn1-M1 mutant that maintains its telomeres through recombination

Some human cancers maintain their telomeres using the alternative lengthening of telomeres (ALT) mechanism; a process thought to involve recombination. Different types of recombinational telomere elongation pathways have been identified in yeasts. In senescing yeast telomerase deletion (ter1-Delta) mutants with very short telomeres, it has been hypothesized that copying a tiny telomeric circle ...
