    • Disclosed is an isolated or purified polypeptide or peptidomimetic comprising an amino acid sequence of a portion of a Smoothened (SMO) protein, wherein the portion comprises an amino acid sequence of any of the intracellular loops of the SMO protein, a functional fragment thereof, or a functional variant of either the portion or the functional fragment, wherein the functional fragment comprises at least 7 contiguous amino acids of the intracellular loops, and wherein the functional fragment or functional variant inhibits proliferation of a diseased cell, or a fatty acid derivative thereof. Related conjugates, nucleic acids, recombinant expression vectors, host cells, and pharmaceutical compositions are further provided. Methods of inhibiting proliferation of a diseased cell, treating or preventing cancer, treating a neoplasm or psoriasis, and inhibiting the expression of genes involved in the Hedgehog signaling pathway, thereby inhibiting the Hedgehog signaling pathway, are furthermore provided by the invention.
    • 公开了一种分离或纯化的多肽或肽模拟物,其包含Smoothened(SMO)蛋白的一部分的氨基酸序列,其中该部分包含SMO蛋白的任何细胞内环的氨基酸序列,其功能片段或 该部分或功能性片段的功能性变体,其中所述功能片段包含细胞内环的至少7个连续氨基酸,并且其中所述功能片段或功能变体抑制病变细胞或其脂肪酸衍生物的增殖。 进一步提供相关缀合物,核酸,重组表达载体,宿主细胞和药物组合物。 本发明进一步提供了抑制病变细胞增殖,治疗或预防癌症,治疗肿瘤或银屑病以及抑制Hedgehog信号通路参与基因表达从而抑制Hedgehog信号通路的方法。
