A Novel Growth Factor and Anti-Apoptotic Agent for Promoting Lung Development and Treating Lung Disease

Posted Jun 15 2010 5:00pm

Description of Invention:
This invention discloses the novel use of the uteroglobin-related protein 1 (UGRP1), also known as secretoglobin family 3A member 2 (SCGB3A2), as a cell proliferative and anti-apoptotic agent that can be used to promote lung development and treat lung disease. SCGB3A2 is a member of the uteroglobin/Clara cell secretory protein or Secretoglobin gene superfamily of secretory proteins that is normally expressed in the epithelial cells of the trachea, bronchus, and bronchioles, and is known for its anti-inflammatory activity. NIH scientists have, however, recently discovered the surprising growth factor and anti-apoptotic activities of SCGB3A2. These activities allow SCGB3A2 to be used to prevent the development of neonatal respiratory distress, promote lung development, and inhibit the lung damage that results from treatment with certain anti-cancer agents such as bleomycin.

SCGB3A2 administration ex vivo and in vivo was shown to enhance cell proliferation and branching morphogenesis. SCGB3A2 was also shown to suppress or repair bleomycin induced DNA damage/fibrosis when given before, or together with bleomycin treatment in in vitro organ culture, and in an in vivo mouse model of pulmonary fibrosis. These cell proliferative and morphogenic effects of SCGB3A2 make it an attractive candidate for therapeutic use in the treatment of several lung diseases that involve tissue injury or inflammation, such as, pulmonary fibrosis, interstitial pneumonia, emphysema and cancer. SCGB3A2 therapy is also envisioned for use as a lung development agent in premature newborn infants born with underdeveloped lungs.

Collaborative Research Opportunity:
The National Cancer Institute, Laboratory of Metabolism is seeking statements of capability or interest from parties interested in collaborative research to further develop, evaluate, or commercialize SCGB3A2 as a clinical tool to treat and/or prevent lung diseases and/or damage caused by various insults including use of the chemotherapeutic agent bleomycin. Lung diseases include pulmonary fibrosis, interstitial pneumonia, emphysema and cancer. We would like to evaluate the effect of SCGB3A2 on the development of emphysema in a smoking model mouse, and as a means to attenuate the severity of all aforementioned diseases in larger animals such as lamb, goat and monkey. We also would like to evaluate the effect of SCGB3A2 on lung maturation using pregnant larger animals. Please contact John D. Hewes, Ph.D. at 301-435-3121 or for more information.
