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.
More than a dozen drugs are known to treat symptoms such as hallucinations, erratic behaviors, disordered thinking and emotional extremes associated with schizophrenia, bipolar disorder and other severe mental illnesses.
For their growth, cells need various nutrients and vitamins. So-called solute carriers (SLC), proteins that can transport such substances across the boundaries of cellular membranes, play a central role in metabolism.
Studies conducted in yeast show that exposure to ultraviolet light (UV) induces new types of DNA damage that may cause the deadliest form of skin cancer, malignant melanoma.
A breakthrough study, led by researchers from the University of California, Irvine, results in the restoration of retinal and visual functions of mice models suffering from inherited retinal disease.
Penn Medicine researchers have solved a decades old mystery around a key molecule fueling the power plant of cells that could be exploited to find new ways to treat diseases, from neurodegenerative disorders to cancer.
Organocatalysts consisting of organic compounds without metal elements are receiving much attention as next generation catalysts in the hope of reducing environmental burden and coping with exhaustion/rising prices of rare metals.
When fast-moving ions cross paths with large biomolecules, the resulting collisions produce many low-energy electrons which can go on to ionise the molecules even further. To fully understand how biological structures are affected by this radiation, it is important for physicists to measure how electrons are scattered during collisions.
A team of researchers from New Jersey Institute of Technology and Children's Hospital of Philadelphia have developed an algorithm through machine learning that helps predict sites of DNA methylation - a process that can change the activity of DNA without changing its overall structure - and could identify disease-causing mechanisms that would otherwise be missed by conventional screening methods.
Researchers from Sweden and Brazil have identified a novel mutation in a strain of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) obtained from a patient in Stockholm, Sweden, in late April.
Researchers from the University of Tsukuba show that long stretches of repeat DNA sequences in the gene FLI1 are associated with susceptibility to systemic sclerosis.
New genome-editing technologies developed by researchers in J. Keith Joung's laboratory at the Massachusetts General Hospital (MGH) have the potential to help understand disease-associated genetic mutations that are based on C-to-G (cytosine to guanine) single base changes.
Increasing the levels of a chemical found in all human cells could boost a woman's fertility and help select the best eggs for IVF, according to University of Queensland research.
A team of researchers from The University of Texas Health Science Center at San Antonio confirmed the role of a certain protein in the development of high-grade kidney cancer.
Familial spinocerebellar ataxia (SCA), Huntington disease, and spinal and bulbar muscular atrophy are inherited neurodegenerative diseases.
DNA damage in general and DNA strand breaks in particular occur every day in all cells of the human body.
A new study published on the preprint server bioRxiv in April 2020 reports the discovery of the structure of the cap created by the novel coronavirus on virally encoded mRNAs. The finding could help create new antiviral strategies.
Many common gut bacteria carry cancer-causing mutations, says a new study published in the journal Nature on the 27th February 2020.
Sleep-deprived fruit flies helped reveal what induces sleep. University of Oxford researchers Anissa Kempf, Gero Miesenböck, and colleagues reveal that fruit fly sleep is driven by oxidative stress, the imbalance of free radicals and antioxidants in the body. Kempf
The reproductive years of a woman are at their peak before the age of 30. Beyond that, fertility starts to decline, and by the age of 40, fertility potential is about half the level it was before 30 years old. Many women experience fertility issues, but now a new study on mice may help reverse the clock on eggs, offering new fertility hope to older women.
Researchers have lifted fertility rates in older female mice with small doses of a metabolic compound that reverses the aging process in eggs, offering hope for some women struggling to conceive.
