Eye pain: 5 cases to test your skill.

The ability to distinguish between ophthalmic emergencies and benign eye conditions is crucial for a family physician. Find out how your skills stack up.

Expression of an engrailed-LMO4 fusion protein in mammary epithelial cells inhibits mammary gland development in mice.

LIM domain factors and associated cofactors are important developmental regulators in pattern formation and organogenesis. In addition, overexpression of two LIM-only factors (LMOs) causes acute lymphocytic leukemia. The more recently discovered LMO factor LMO4 is highly expressed in proliferating epithelial cells, and frequently overexpressed in breast carcinoma.

Identification and characterization of Grainyhead-like epithelial transactivator (GET-1), a novel mammalian Grainyhead-like factor.

LMO-4 is an LIM-only factor that is highly expressed in many epithelial cells, including those of the epidermis and hair follicles. Because LMOs may function by interacting with DNA-binding proteins, we have used the yeast two-hybrid system to screen mouse skin libraries for LMO-4-interacting DNA-binding proteins. In this screen, we isolated a novel LMO-4-interacting factor highly related to the Drosophila gene Grainyhead.
