DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

How bacterial cells have been engineered to produce virus-resistant synthetic polymers

A recent Science paper discusses the utilization of a previously reported synthetic Escherichia coli to produce virus-resistant synthetic polymers.

Study shows how the physical nature of genome changes before and after cell differentiation

The organization of the human genome relies on physics of different states of matter - such as liquid and solid - a team of scientists has discovered. The findings, which reveal how the physical nature of the genome changes as cells transform to serve specific functions, point to new ways to potentially better understand disease and to create improved therapies for cancer and genetic disorders.

Epigenetic regulation affects the 3D structure of genome

All the cells of an organism share the same DNA sequence, but their functions, shapes or even lifespans vary greatly. This happens because each cell "reads" different chapters of the genome, thus producing alternative sets of proteins and embarking on different paths.

Nanopore sequencing contradicts human genome integration of SARS-CoV-2

Now a new preprint research paper posted to the bioRxiv* server dismisses the possibility, raised by that study, that the virus inserts its genetic material into the host cell’s genome.

Could semen quality indicate SARS-CoV-2 insult susceptibility in polluted areas?

In a recent review in Environmental Science and Pollution Research, Italian researchers focused on “the evidence that correlates the degree and type of pollution with the increased susceptibility of many countries to this pandemic and proposes human semen as an early marker of the environmental health and the general health of individuals.” Their observations are based on a robust body of experimental evidence.

Synthetic microRNA can serve as a novel therapeutic agent for treating human cancer

Oncotarget published "Multi-modal effects of 1B3, a novel synthetic miR-193a-3p mimic, support strong potential for therapeutic intervention in oncology" which reported that the authors comprehensively investigated miRNA-193a-3p's mode of action in a panel of human cancer cell lines, with a variety of genetic backgrounds, using 1B3, a synthetic microRNA mimic

Molecular subtype of cancer preferentially affects people with Indigenous ancestry

Oncotarget published "Global DNA hypermethylation pattern and unique gene expression signature in liver cancer from patients with Indigenous American ancestry" which reported that contrasting with this pattern, the age structure of HCC in Andean people displays a bimodal distribution with half of the patients developing HCC in adolescence and early adulthood.

New project aims to develop technologies for quantifying cancer and viral biomarkers

Liquid biopsy, the detection of circulating disease biomarkers in bodily fluids such as blood, is a non-invasive method, alternative to tissue removal, which has taken important strides toward the implementation of personalized medicine, especially in the case of tumors and RNA-viruses.

UCL researchers measure mass of human chromosomes with X-rays for the first time

The mass of human chromosomes, which contain the instructions for life in nearly every cell of our bodies, has been measured with X-rays for the first time in a new study led by UCL researchers.

Researchers discover a new and unique form of ALS

In a study of 11 medical-mystery patients, an international team of researchers led by scientists at the National Institutes of Health and the Uniformed Services University discovered a new and unique form of amyotrophic lateral sclerosis (ALS).

Could a mathematical application of information theory identify and predict SARS-CoV-2 mutations?

An interesting new study by researchers at the University of Portsmouth, UK, describes the use of a mathematical method to sequence genomes based on information theory. The method offers an alternative to clinical techniques, allowing mutations to be detected and possibly even predicted. In this way, it opens new research opportunities in bioinformatics and genetics.

Study could help identify risk of secondary leukaemia in certain children

Scientists from the Wellcome Sanger Institute and the University of Cambridge found that in children with neuroblastoma - a cancer of immature nerve cells - treatment with platinum chemotherapy caused changes to the genome that could then cause leukaemia in some children later on.

Harnessing DNA’s properties to craft “‘topologically tunable” DNA-based materials

While DNA is often idealized as the "molecule of life", it is also a highly sophisticated polymer that can be used for next-generation materials. Beyond the fact that it can store information, further fascinating aspects of DNA are its geometric and topological properties, such as knotting and super-coiling.
