    • A novel family of growth regulatory proteins termed "epithelins" are described. The epithelins comprise several distinct members sharing significant structural homology. Two members of the epithelin family, epithelin 1 and epithelin 2, have been purified from natural sources. In addition, cDNA and PCR clones encoding mature and precursor epithelins from various chordate sources have been obtained and sequenced, including the complete human, mouse and rat epithelin precursors. The recombinant expression of rat epithelin precursor and mature forms is described. Purified epithelin 1 is a bifunctional growth regulator, capable of stimulating the growth of some cell types while inhibiting the growth of others. Purified epithelin 2 is functionally similar to epithelin 1 with respect to growth inhibitory bioactivity. In contrast, however, epithelin 2 is apparently not capable of eliciting the growth stimulatory activity characteristic of epithelin 1 and, in fact, antagonizes this epithelin 1 activity.

    • A novel cell growth regulatory factor, named Amphiregulin, is described. This extremely hydrophilic glycoprotein, having a median molecular weight of 22,500 daltons, demonstrates unusual biological activity. Amphiregulin is a bifunctional cell growth regulatory factor which exhibits potent inhibitory activity on DNA synthesis in neoplastic cells, yet promotes the growth of certain normal cells. The invention is based, in part, on the discovery that MCF-7 cells, when treated with the tumor promoting agent, 12-O-tetradecanoyl-phorbol-13-acetate (TPA), express and secrete two distinct yet functionally equivalent forms of Amphiregulin. These two forms are structurally identical and perfectly homologous except that the truncated form lacks an amino-terminal hexapeptide found in the larger form. The Amphiregulin gene has been cloned and used to construct plasmids which direct the expression of bioactive Amphiregulin in transformed Escherichia coli cells. A wide variety of uses for Amphiregulin are encompassed by the present invention, including the treatment of wounds and cancers.
    • 描述了一种称为Amphiregulin的新型细胞生长调节因子。 中性分子量为22,500道尔顿的极亲水性糖蛋白表现出不寻常的生物活性。 双调蛋白是双功能细胞生长调节因子,其对肿瘤细胞中的DNA合成显示出有效的抑制活性,但促进某些正常细胞的生长。 本发明部分基于发现当用肿瘤促进剂12-O-十四酰基 - 佛波醇-13-乙酸酯(TPA)处理时,MCF-7细胞表达和分泌两种不同但功能上等同的形式 双调蛋白 这两种形式在结构上是完全相同的,除了截短的形式缺少以更大形式发现的氨基末端六肽外。 已经克隆了Amphiregulin基因并用于构建转化大肠杆菌细胞中生物活性Amphiregulin表达的质粒。 本发明包括双调蛋白的广泛用途,包括伤口和癌症的治疗。
