    • Novel, isolated, substantially pure, hydrophobic surfactant-associated protein of 6,000 daltons simple molecular weight (SAP-6). When SAP-6 is combined with lipids, its surfactant-like property imparts to the combination significant pulmonary biophysical activity. Such a combination results in enhanced adsorption of the lipids with properties similar to that of natural pulmonary surfactant material. SAP-6 in combination with lipids is highly useful for replacing or supplementing natural pulmonary surfactant material for reducing or maintaining normal surface tension in the lungs, especially in the lungs of patients suffering from hyaline membrane disease (HMD), or other syndromes associated with the lack or insufficient amounts of natural pulmonary surfactant material. A combination of SAP-6 and lipids may be administered as an aerosol spray or in aqueous normal saline with or without calcium chloride for treating or preventing HMD and other surfactant deficiency states. Also disclosed are methods of isolating the SAP-6 from animal tissue.
    • 具有6000道尔顿简单分子量(SAP-6)的新型,分离,基本纯净的疏水表面活性剂相关蛋白。 当SAP-6与脂质组合时,其类似表面活性剂的特性赋予组合显着的肺生物物理活性。 这种组合导致具有与天然肺表面活性剂材料类似的性质的脂质的增强的吸附。 与脂质组合的SAP-6非常适用于替换或补充天然肺表面活性剂材料,以降低或维持肺中正常的表面张力,特别是在患有透明膜疾病(HMD)或与其相关的其他综合征的患者的肺中 天然肺表面活性物质的量不足或不足。 SAP-6和脂质的组合可以作为气溶胶喷雾剂或含有或不含氯化钙的水性生理盐水施用,用于治疗或预防HMD和其它表面活性剂缺乏状态。 还公开了从动物组织分离SAP-6的方法。

    • The present invention relates to novel continuous human adenocarcinoma cell lines of epithelial lung tissue origin that produce fully processed or semi-processed surfactant-associated proteins, e.g., SAP-35 and SPL(Phe). The surfactant-associated proteins confer biological activity to pulmonary surfactant phospholipids and are useful for formulating pulmonary surfactant replacement for, inter alia, diagnosis and therapy of human diseases associated with surfactant deficiency. Exemplary cell lines of the present invention designated as NCI-H441-4, NCI-H820, NCI-H322 and NCI-H1404 are deposited with the American Type Culture Collection (ATCC) of Rockville, Maryland under accession Nos. CRL 9400, CRL 9531, CRL 9532 and CRL 9533, respectively. The present invention also relates to a novel method for regulating the expression of a surfactant-associated protein by cells having the ability to express at least one surfactant-associated protein and/or mRNA encoding therefore by exposing the cells to a regulating agent, such as a glucocorticoid hormone, 8-Br-cAMP or a functional equivalent, to selectively induce or inhibit the expression of a surfactant-associated protein. The present invention is also directed to novel methods to screen for tumor cells of pulmonary epithelial origin which produce surfactant-associated proteins and purifying the proteins from lysates of the cells or the media. The present invention also relates to novel human proteins, Mr=40-46,000, Mr=27-33,000 and Mr=23,000 on SDA-PAGE, which are believed to be precursors of the SPL(Phe) human protein. The SPL(Phe) mRNA initially translates an Mr=40-42,000 preproprotein which is glycosylated at asparagine residues and sialylated resulting in an Mr=40-46,000 SPL(Phe) proprotein. The Mr=27-33,000 protein is a proteolytically cleaved fragment of the Mr=40-46,000 precursor, and the Mr=23,000 protein results from de-glycosylating and de-sialylating the Mr=27-33,000 protein.
