MicroRNA makes triple-negative breast cancer homesick
Epithelial cells are homebodies – they like to attach to things and becoming detached initiates a form of cell suicide known as anoikis (literally "homeless" in Latin). But in order for cancer cells to metastasize they ...

Landmark study describes prostate cancer metastasis switch
Prostate cancer doesn't kill in the prostate – it's only once the disease travels to bone, lung, liver, etc. that it turns fatal. Previous studies have shown that loss of the protein E-Cadherin is essential for this metastasis. ...

Epithelium
In biology and medicine, an epithelium is a tissue composed of cells that line the cavities and surfaces of structures throughout the body. Many glands are also formed from epithelial tissue. It lies on top of connective tissue, and the two layers are separated by a basement membrane.
In humans, epithelium is classified as a primary body tissue, the other ones being connective tissue, muscle tissue and nervous tissue.
Epithelium is often defined by the expression of the adhesion molecule e-cadherin (as opposed to n-cadherin, which is used by cells of the connective tissue).
Functions of epithelial cells include secretion, selective absorption, protection, transcellular transport and detection of sensation and they commonly as a result present extensive apical-basolateral polarity (e.g. different membrane proteins expressed) and specialisation.
