    • The invention provides methods of determining in situ the EMT status of the cells of a tumor in a patient in vivo, including: (a) providing an EMT-status-detecting conjugate containing an antibody that binds to an EMT-status biomarker, and a reporter molecule; (b) introducing the conjugate into a patient with a tumor, such that the conjugate contacts the EMT-status biomarker of the cells of the tumor; (c) employing a means for detection of the signal from the conjugate at the tumor site; and (d) using a means for image analysis to localize and quantify the signal from the conjugate at the tumor site, a positive signal indicating the presence of epithelial tumor cells if the EMT-status biomarker is an epithelial biomarker, and mesenchymal tumor cells if the EMT-status biomarker is a mesenchymal biomarker. Such methods are useful for diagnosing patients who might benefit from treatment with drugs such as EGFR or IGF-1R kinase inhibitors, and for identifying and testing agents that inhibit tumor cells from undergoing an epithelial to mesenchymal transition. This invention also provides the above methods where an AFFIBODY® molecule that binds to an EMT-status biomarker is used instead of an antibody.
    • 本发明提供了在体内确定患者体内肿瘤细胞的EMT状态的方法,包括:(a)提供包含结合EMT状态生物标志物的抗体的EMT状态检测缀合物,以及 报告分子; (b)将缀合物引入患有肿瘤的患者中,使得缀合物与肿瘤细胞的EMT状态生物标志物接触; (c)采用在肿瘤部位检测来自缀合物的信号的方法; 和(d)使用图像分析方法来定位和量化来自肿瘤位点的缀合物的信号,如果EMT状态生物标志物是上皮生物标志物,则表示存在上皮肿瘤细胞的阳性信号,以及间质肿瘤细胞 EMT状态生物标志物是间充质生物标志物。 这样的方法可用于诊断可能受益于诸如EGFR或IGF-1R激酶抑制剂的药物治疗的患者,以及用于鉴定和测试抑制肿瘤细胞经历上皮至间质转化的试剂。 本发明还提供了上述方法,其中使用结合EMT状态生物标志物的AFFIBODY分子代替抗体。

    • A screening assay in yeast is disclosed wherein G-protein coupled-receptor independent activators and inhibitors of the pheromone pathway can be identified using a mammalian cDNA library. Novel Activator of G protein Signaling (nullAGSnull) proteins, which are Ras-related proteins that stimulate G protein activity in a receptor-independent manner, are disclosed, as well as nucleic acid molecules encoding AGS proteins. In addition to isolated AGS proteins, the invention further provides isolated AGS fusion proteins, antigenic peptides and anti-AGS antibodies. The invention also provides isolated AGS nucleic acid molecules, recombinant expression vectors containing a nucleic acid molecule of the invention, host cells into which the expression vectors have been introduced and non-human transgenic animals in which an AGS gene has been introduced or disrupted. Diagnostic, screening and therapeutic methods utilizing compositions of the invention are also provided.
