Scientists at the Salk Institute have identified a key genetic switch linked to the development, progression and outcome of cancer, a finding that may lead to new targets for cancer therapies. The switch, a string of amino acids dubbed a long non-coding RNA (lncRNA), does not code for proteins like regular RNA. Instead, the scientists found, this particular lncRNA acts as an on/off switch for a key gene, COX-2, whose excessive activity is tied to inflammation and cancer.

A mutation as minute as swapping just one amino acid can completely change the target that a virus will bind to on a victim cell — potentially shifting what kind of cell and eventually what kind of organism a virus could infect.

The boundary between electronics and biology is blurring with the first detection by researchers at Department of Energy's Oak Ridge National Laboratory of ferroelectric properties in an amino acid called glycine.

Researchers found that when deprived of oxygen, cancer cells (and many other mammalian cells) can engage an alternate metabolic pathway that allows them to use glutamine, a plentiful amino acid, as the starting material for synthesizing fatty molecules known as lipids. These lipids are essential components of many cell structures, including cell membranes.

If Guinness World Records had a category for the largest human-designed protein, then a team of Vanderbilt chemists would have just claimed it. They have designed and successfully synthesized a variant of a protein that nature uses to manufacture the essential amino acid histidine. It is more than twice the size of the previous record holder, a protein created by researchers at the University of Washington in 2003.
