Adenine is one of the four bases in DNA that make up the letters ATGC, adenine is the "A". The others are guanine, cytosine, and thymine. Adenine always pairs with thymine.
St. Jude Children's Research Hospital scientists have developed an integrated, high-throughput system to better understand and possibly manipulate gene expression for treatment of disorders such as sickle cell disease and beta thalassemia. The research appears today in the journal Nature Genetics.
Small changes in the structure of DNA have been implicated in breast cancer and other diseases, but they've been extremely difficult to detect -- until now.
A natural compound previously demonstrated to counteract aspects of aging and improve metabolic health in mice has clinically relevant effects in people, according to new research at Washington University School of Medicine in St. Louis.
Researchers at GMI - Gregor Mendel Institute of Molecular Plant Biology of the Austrian Academy of Sciences - and the John Innes Centre, Norwich, United Kingdom, determine that gene-regulatory mechanisms at an early embryonic stage govern the flowering behavior of Arabidopsis later in development. The paper is published in the journal PNAS.
The human genome contains the instructions to make tens of thousands of proteins. Each protein folds into a precise shape-;and biologists are taught that defined shape dictates the protein's destined function.
In a series of experiments that began with amoebas -- single-celled organisms that extend podlike appendages to move around -- Johns Hopkins Medicine scientists say they have identified a genetic pathway that could be activated to help sweep out mucus from the lungs of people with chronic obstructive pulmonary disease a widespread lung ailment.
Researchers of the Hubei University of Medicine, China, have analyzed several mutations in different variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from mammal species that suggest natural selection and host adaptation are occurring in the virus.
A new study describes the identification of new compounds from a library, with inhibitory activity against several coronaviruses. This study shows the utility of this method, besides identifying compounds that not only inhibit viral shedding in SARS-CoV-2 cultures, but have an immunomodulatory effect that may be useful in mitigating the damaging cytokine storm typical of severe or critical COVID-19.
The latest gene editing technology, prime editing, expands the "genetic toolbox" for more precisely creating disease models and correcting genetic problems, scientists say.
In the past few years, several medications have been found to be contaminated with NDMA, a probable carcinogen. This chemical, which has also been found at Superfund sites and in some cases has spread to drinking water supplies, causes DNA damage that can lead to cancer.
A team of researchers from the Agency for Science, Technology and Research's (A*STAR) Genome Institute of Singapore have developed a CRISPR-based gene editor, C-to-G Base Editor (CGBE), to correct mutations that cause genetic disorders.
An interesting new study by researchers at the University of Liverpool, University of Bristol and Public Health England in the UK describes a novel bioinformatics tool used to detect subgenomic messenger ribonucleic acid (mRNA) sequences from the virus. This may help develop new diagnostic tools and model the transmission of the virus.
In 1993, scientists discovered that a single mutated gene, HTT, caused Huntington's disease, raising high hopes for a quick cure. Yet today, there's still no approved treatment.
The current pandemic of coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is still spreading rapidly throughout the world. A new preprint on the bioRxiv* server describes the structure of an important viral non-structural protein NSP12-16 and its role in SARS-CoV-2 infection.
A new study in the Journal of dietary supplements shows that nutritional supplements, including several vitamins and the mineral zinc, may be useful in preventing the infection or reducing its severity if caught.
A team of scientists from the USA and Germany has recently studied the evolution of SARS-CoV-2 in a representative set of sequences from the USA collected between 2020 and 2021. The findings reveal that the viral genome has accumulated multiple mutations over time with only occasional loss of mutation. The main driving forces behind such genetic variations include widespread infection and superspreader events.
New research from the University of Iowa and University Hospitals Cleveland Medical Center demonstrates that offspring can be protected from the effects of prenatal stress by administering a neuroprotective compound during pregnancy.
In a technique known as DNA origami, researchers fold long strands of DNA over and over again to construct a variety of tiny 3D structures, including miniature biosensors and drug-delivery containers.
There is growing evidence to support the hypothesis that there is a neurodevelopmental component to the late-onset neurodegeneration occurring in the brain of huntingtin gene (HTT gene) mutation carriers, and that this increased susceptibility to brain cell death begins during childhood.
Just like other organisms, plants must respond dynamically to a variety of cues over their lifetime. Going through different developmental stages, or altering their form in response to a drought or drastic temperature change requires altering which of their genes are expressed into proteins and when those processes occur.
