Inadequate Supply of Protein Building Blocks May Explain Pregnancy Failures in Bovine Cloning Experiments
Amino acids, the building blocks of proteins, are essential to support the normal growth of a developing embryo and the placenta. An insufficient supply of amino acids in the mother's uterus caused by abnormal maternal-embryo interactions may
Functional Amino Acids Regulate Key Metabolic Pathways
Functional amino acids play a critical role in the development of both animals and humans, according to a Texas AgriLife Research scientist.
In a journal article appearing in the American Society for Nutrition (Advances in Nutrition 1:31-37, 2010),
A Protein Shows Plants the Oxygen Concentration of Their Surroundings
Plants need water to grow, but every hobby gardener knows that you shouldn’t carry this to excess either. During waterlogging or flooding, plants can’t take up enough oxygen that they urgently need for their cellular respiration and energy production. Plants respond to this state of hypoxia with the activation of certain genes that help them cope with the stress.
Protein Found That Improves DNA Repair Under Stress
Cells in the human body are constantly being exposed to stress from environmental chemicals or errors in routine cellular processes. While stress can cause damage, it can also provide the stimulus for undoing the damage. New research by a team of scientists at the University of Rochester has unveiled an important new mechanism
Cells Have Early-Warning System for Intruders
When a thief breaks into a bank vault, sensors are activated and the alarm is raised. Cells have their own early-warning system for intruders,
