Diagnostics and Therapeutics for Hydrocephalus

Description of Technology: Congenital hydrocephalus is a significant public health problem, affecting approximately one in 500 live births in the United States. Congenital hydrocephalus has an adverse effect on the developing brain and may persist as neurological defects in children and adults. Some of these defects may manifest as mental retardation, cerebral palsy, epilepsy and visual disabilities. Improved diagnostics are needed for assessing the risks of developing this debilitating disease.

The inventors have shown that RFX4_v3, a splice variant of the Regulatory Factor X4 (RFX4) transcription factor, is associated with the development of neurological structures. The reduction or absence of RFX4-v3 promotes the development of congenital hydrocephalus. This invention describes RFX4_v3 polypeptides and nucleic acids, as well as methods for detection of RFX4_v3 polymorphisms associated with congenital hydrocephalus. Also described are treatment methods including the RFX4-v3 polypeptide and RFX4-v3 transgenic animals and antibodies.

Applications: Prenatal diagnostic assay for identifying children at risk for congenital hydrocephalus; Genotyping assay for congenital hydrocephalus.

Market: In the United States, the health care costs for congenital hydrocephalus are estimated at $100 million per year.

Development Status: In vitro data are available.

Epithelial Cell Line Expressing a Cystic Fibrosis Phenotype

Description of Technology: Cystic fibrosis (CF) is a common genetic disease that affects the entire body, producing thick, sticky mucus that clogs the lungs, pancreas, and other organs. It is the most common fatal genetic disease in the United States, and is caused by a mutation in the cystic fibrosis transmembrane conductance regulator (CFTR).

Researchers at NIEHS have developed a cell line, CF/T43, which was produced by infection of airway epithelial cells isolated from CF patients with an SV40T retrovirus. CF/T43 cells maintain the abnormal ion transport characteristics of CF while having proliferation capability beyond that of a primary epithelial cell culture. Key features of the CF/T43 cell line include the formation of functional tight junctions, reduced apical membrane chloride conductance, and activation of apical chloride channels by calcium ionophores but not by cAMP-dependent agonists. This cell line may be used for elucidation of the mechanisms of CF, testing candidate complementary genes for correction of the observed CF abnormalities, and for developing and testing therapeutic CF drugs.

Applications: Research tool for developing new therapies to treat cystic fibrosis; Research tool for studying the mechanisms of cystic fibrosis.
