Vitamin A is a nutrient that the body needs in small amounts to function and stay healthy. Vitamin A helps in vision, bone growth, reproduction, growth of epithelium (cells that line the internal and external surfaces of the body), and fighting infections. It is fat-soluble (can dissolve in fats and oils). Vitamin A is found in liver, egg yolks, and whole milk dairy products from animals and in fish oils. It can also be made in the body from a substance found in some fruits and vegetables, such as cantaloupes, carrots, spinach, and sweet potatoes. Vitamin A is being studied in the prevention and treatment of some types of cancer. Also called retinol.
Scientists at the Princeton University Branch of the Ludwig Institute for Cancer Research have identified novel mechanisms by which a metabolic derivative of vitamin A-all-trans retinoic acid-compromises both the body's normal anti-cancer immune response and, in a different context, the efficacy of a promising type of cancer vaccine.
Carrots are rich in carotenoids, essential for human health, providing important compounds like vitamin A.
More than one-sixth of adults around the world experience infertility in their lifetime. There is a high unmet need not only for increased access to affordable, high-quality fertility care for those in need but, importantly, also for new biomedical solutions that can address the root causes of infertility.
By flipping an evolutionarily disabled genetic switch involved in Vitamin A metabolism, researchers have enabled ear tissue regeneration in mice. Unlike some animals such as fish and salamanders, mammals have limited capacity to regenerate damaged tissues or organs fully.
Scientists have for the first time looked deep into the protein structure that may determine our vision - and discovered that it is much more dynamic than previously thought.
The study reveals 44 differentially expressed proteins in cleft palate models, shedding light on molecular mechanisms and potential prenatal diagnostic markers.
When it comes to survival, plants have a huge disadvantage compared to many other living organisms: they cannot simply change their location if predators or pathogens attack them or the environmental conditions change to their disadvantage.
A group of researchers in Newcastle has been investigating the part that vitamin A plays in the pathogenesis of psychiatric disorders.
A recent study in the Journal of Biological Chemistry revealed the key to a protein that commonly causes blindness.
Consuming a diet rich in vitamin A or its analogs may help prevent children and young adults with acute lymphoblastic leukemia (ALL) reduce their risk of developing painful pancreas inflammation during chemotherapy treatment.
In the regulation of hematopoietic stem cells—which are the immature stem cells that produce all the blood cell lineages—the cell protein retinoid X receptor (RXR) is an important element.
Manipulating the content of carotenoids, such as ß-carotene, has been found to improve plant growth and increase yield and tolerance to abiotic stresses such as drought and salinity.
Buying tomatoes and other fruits in the grocery store is always a gamble because, however good they look, they are often firm but lack flavor.
A team of scientists at the University of Illinois Urbana-Champaign developed a bioprocess using engineered yeast that completely and efficiently converted plant matter consisting of acetate and xylose into high-value bioproducts.
According to a new study reported in Nature Scientific Reports, Methylene Blue, a century-old medication, can be a very efficient, broad-spectrum UV irradiation protector that absorbs UVA and UVB, repairs ROS and UV irradiation-induced DNA damage, and is safe for coral reefs.
Researchers have genetically engineered a probiotic yeast to produce beta-carotene in the guts of laboratory mice. The advance demonstrates the utility of work the researchers have done to detail how a suite of genetic engineering tools can be used to modify the yeast.
Neuroscientists agree that a person's brain is constantly changing, rewiring itself and adapting to environmental stimuli. This is how humans learn new things and create memories. This adaptability and malleability is called plasticity.
Scientists from Peter the Great St. Petersburg Polytechnic University (SPbPU) have successfully produced microalgae biomass that has a high content of carotenoid pigments, which is suitable for the food sector.
The study concludes that vegan diet has a broad effect on children's metabolism. Serum biomarker levels for vitamins A and D, cholesterol forms and essential amino acids were significantly lower in children on vegan diet compared to age-adjusted omnivores.
Carrots are a good source of beta-carotene, which is a precursor of vitamin A. But to get the full health benefits of this superfood, you need an active enzyme to produce this vitamin.
