Tryptophan is one of the 20 standard amino acids, as well as an essential amino acid in the human diet.
A Nebraska-led coming attraction may soon pop into a global blockbuster. Through a decade-long project supported by Conagra Foods, a University of Nebraska–Lincoln research team led by David Holding has naturally bred new varieties of popcorn that outperform today's most popular kernels in their intrinsic nutritional value and taste.
Plant viruses are of great variety and harm. Virus disease pandemics and epidemics were estimated to have a global economic impact in the tens of billions of dollars.
Which came first, MHC class I or MHC class II? For decades, it has been debated which of these two similar classes came first in evolution. Now, Keiichiro Hashimoto and his group at Fujita Health University, Japan, in collaboration with European research groups, have provided an answer to this question in a new article in PNAS.
Decreasing bacterial acidity could help reduce antimicrobial resistance by eliminating bacteria that can survive being treated with antibiotics.
A cutting-edge digital tool that will make it cheaper, safer and faster for pharmaceutical companies to predict protein stability - a vital step in the development of new medicines - is being rolled out by scientists from the UK's University of Bath through their spin-out company, BLOC Labs.
Brain tumor cells with a certain common mutation reprogram invading immune cells. This leads to the paralysis of the body's immune defense against the tumor in the brain. Researchers from Heidelberg, Mannheim, and Freiburg discovered this mechanism and at the same time identified a way of reactivating the paralyzed immune system to fight the tumor.
Researchers used metagenomic sequencing to identify variations in virus and bacterial populations that occur following spinal cord injury in mice.
Our immune system is very successful when it comes to warding off viruses and bacteria. It also recognizes cancer cells as potential enemies and fights them. However, cancer cells have developed strategies to evade surveillance by the immune system and to prevent immune response.
The gut microbiome is considered an essential part of the body, but its significance in the human aging process is still vague.
Investigators from the Institute of Scientific and Industrial Research at Osaka University, together with the Hiroshima Institute of Technology, have announced the discovery of a new protein that allows an organism to conduct an initial and essential step in converting amino acid residues on a crosslinked polypeptide into an enzyme cofactor.
Pictures of a protein that plays a key role in the production of a potent antibiotic have disclosed the first unusual steps involved in the synthesis of antibiotics.
Cancers like melanoma are hard to treat, not least because they have a varied bag of tricks for defeating or evading treatments.
Biologists have analyzed the genes that establish the composition of fatty acids in flaxseed oil and detected polymorphisms in six of those genes.
A new study by scientists at UNC Lineberger Comprehensive Cancer Center and colleagues published Oct. 30, 2020, in Science, showed that mice exposed to potentially lethal levels of total body radiation were protected from radiation damage if they had specific types of bacteria in their gut.
The metabolic enzyme IL4I1 (Interleukin-4-Induced-1) promotes the spread of tumor cells and suppresses the immune system.
The SARS-CoV-19 virus initially has a limited capability to invade, attacking only one intracellular genetic target, the aryl hydrocarbon receptors (AhRs).
Research has offered insight into the roles played by a pair of essential amino acids in metabolic health. This insight may help researchers to combat obesity.
