The transporter protein ABCG2 belongs to the ATP-binding-cassette (ABC) family. The protein is expressed in the plasma membranes of cells within a variety of tissues and tissue barriers, including the blood-brain, blood-testes ...
A well-accepted principle in the animal kingdom—from wasps to deer—is that creatures already occupying a habitat nearly always prevail over competitors from the same species that arrive later. Such infighting for the ...
Most malaria drugs are designed to reduce symptoms after infection. They work by blocking replication of the disease-causing parasites in human blood, but they don't prevent infection or transmission via mosquitoes. What's ...
Botryllus schlosseri, a marine invertebrate that lives in underwater colonies resembling fuzzy pinheads clinging to rocks, has a blood-forming system with uncanny similarities to that of humans, according to scientists at ...
An active protein component of royal jelly helps honeybees create new queens. Stanford researchers have identified a similar protein in mammals, which keeps cultured embryonic stem cells pluripotent.
A bacterial toxin that allows an infectious strain of bacteria to defeat its competitors has been discovered by Imperial College London scientists.
A previously unappreciated interaction in the genome turns out to have possibly been one of the driving forces in the emergence of advanced life, billions of years ago.
Regulation of gene expression—turning genes on or off, increasing or decreasing their expression—is critical for defining cell identity during development and coordinating cellular activity throughout the cell's lifetime. ...
The ammonia oxidizing archaea, or Thaumarchaeota, are among the most abundant marine microorganisms. Yet, scientists are still discovering which factors allow them to thrive in the ocean. A research team from the Max Planck ...
Min Dong, Ph.D., and his lab are world experts in toxins and how to combat them. They've figured out how Clostridium difficile's most potent toxin gets into cells and zeroed in on the first new botulinum toxin identified ...
