title: Lymphatic vessel abnormalities arising from disorders of Ras signal transduction.
abstract: A number of genetic diseases in man have been described in which abnormalities in the development and function of the lymphatic vascular (LV) system are prominent features. The genes that are mutated in these diseases are varied and include genes that encode lymphatic endothelial cell (LEC) growth factor receptors and their ligands and transcription factors that control LEC fate and function. In addition, an increasing number of genes have been identified that encode components of the Ras signal transduction pathway that conveys signals from cell surface receptors to regulate cell growth, proliferation, and differentiation. Gene targeting studies performed in mice have confirmed that the LV system is particularly susceptible to perturbations in the Ras pathway.
