Heterozygosity of CANP3, ACTN3, and GHR genes in specialized collections was studied using state-of-the-art DNA technologies for DNA analysis. A new dinucleotide deletion (AC) at the beginning of exon 21 was identified in five individuals with heterozygous CANP3 gene. Analysis of polymorphism (SNP1747 C-->T) of ACTN3 gene demonstrated a positive association of allele C with a high muscular performance. Real-time PCR assay of SNP1630 (A-->C) in GHR gene suggested a putative negative association of allele C of this SNP with a high muscular performance.

Retroviruses can be detected by the innate immune sensor cyclic GMP-AMP synthase (cGAS), which recognizes reverse-transcribed DNA and activates an antiviral response. However, the extent to which HIV-1 shields its genome from cGAS recognition remains unclear. To study this process in mechanistic detail, we reconstituted reverse transcription, genome release, and innate immune sensing of HIV-1 in a cell-free system.

It has been well accumulated that G-quadruplex (G4-DNA) has great anticancer relevance, and various heterocyclic moieties have been synthesized and examined as potent G4-DNA binders with promising anticancer activity. Here, we have synthesized a series of naphthalimide-triazole-coumarin conjugates by substituting various amines and further examine their anticancer activity against 60 human cancer cell lines at 10 μM. One and five dose concentration results reveal low values of MG-MID GI for compounds including (3.

Background: The incidence of skin cancer among Danes is one of the highest in the world. Most skin cancers are, however, avoidable with sun protection and reduction of exposure. One way to increase awareness could be through personal biofeedback information about skin DNA damage.

Hybrid quantum-classical computing algorithms offer significant potential for accelerating the calculation of the electronic structure of strongly correlated molecules. In this work, we present the first quantum simulation of conical intersections (CIs) in a biomolecule, cytosine, using a superconducting quantum computer. We apply the contracted quantum eigensolver (CQE)─with comparisons to conventional variational quantum deflation (VQD)─to compute the near-degenerate ground and excited states associated with the conical intersection, a key feature governing the photostability of DNA and RNA.
