Tumor suppressor gene
A protective gene that normally limits the growth of tumors. When a tumor suppressor gene is mutated (altered), it may fail to keep a cancer from growing.
BRCA1, an example of a tumor suppressor gene, was the first breast cancer gene to be identified; mutated forms of this gene are responsible for some cases of inherited breast cancer, especially those that occur in younger women.

- UAA
A triplet consisting of uracil, adenine, adenine, in that order, that acts as a stop codon in messenger RNA (mRNA), signaling the termination of translation of an mRNA molecule and the release of the nascent polypeptide chain.
- UAG
A triplet consisting of uracil, adenine, guanine, in that order, that acts as a stop codon in messenger RNA (mRNA), signaling the termination of translation of an mRNA molecule and the release of the nascent polypeptide chain.
- UAL
UAL stands for ultrasonic-assisted liposuction. Liposuction involves the surgical suctioning of fat deposits from specific parts of the body, the most common being the abdomen (the “tummy”), buttocks (“behind”), hips, thighs and knees, chin, upper arms, back, and calves. Liposuction breaks up and “sucks” fat out of the body. This is done through a cannula […]
- Ubiquitin
A small but extremely important protein that acts the “kiss of death” to other proteins. Ubiquitin consists of only 76 amino acids. In the normal course of events, proteins are inactivated by the attachment of ubiquitin to them, a process called ubiquitination. Ubiquitin acts as a tag by which the protein-transport machinery ferries a protein […]
- Ubiquitous
Present everywhere. The small protein called ubiquitin was so-named because it is present in all types of cells and its amino acid sequence is identical in all creatures from insects to humans.
