    摘要: The emergence of mutations in tyrosine kinases following treatment of cancer patients with molecular-targeted therapy represents a major mechanism of acquired drug resistance. Here, we describe a mutation in the serpentine receptor, Smoothened (SMO), which results in resistance to a Hedgehog (Hh) pathway inhibitor in medulloblastoma. A single amino acid substitution in a conserved aspartic acid residue of SMO maintains Hh signaling, but results in the inability of the Hh pathway inhibitor, GDC-0449, to bind SMO and suppress the pathway. This mutation was not only acquired in a GDC-0449-resistant mouse model of medulloblastoma, but was identified in a Medulloblastoma patient following relapse on GDC-0449. The invention provides screening methods to detect SMO mutations and methods to screen for drugs that specifically modulate mutant SMO exhibiting drug resistance.

    摘要: Isolated thrombopoietin (TPO), isolated DNA encoding TPO, and recombinant or synthetic methods of preparing and purifying TPO are disclosed. Various forms of TPO are shown to influence the replication, differentiation or maturation of blood cells, especially megakaryocytes and megakaryocyte progenitor cells. Accordingly, these compounds may be used for treatment of thrombocytopenia.

    摘要: The emergence of mutations in tyrosine kinases following treatment of cancer patients with molecular-targeted therapy represents a major mechanism of acquired drug resistance. Here, we describe a mutation in the serpentine receptor, Smoothened (SMO), which results in resistance to a Hedgehog (Hh) pathway inhibitor in medulloblastoma. A single amino acid substitution in a conserved glutamic acid residue of SMO maintains Hh signaling, but results in the inability of the Hh pathway inhibitor, GDC-0449, to bind SMO and suppress the pathway. The invention provides screening methods to detect SMO mutations and methods to screen for drugs that specifically modulate mutant SMO exhibiting drug resistance.
