This invention is directed to methods and compositions for diagnosis, prognosis and for determining methods of treatment. The physiological status of cells present in a sample (e.g. clinical sample) can be used in diagnosis or prognosis of a condition (e.g. Chronic Lymphocytic Leukemia), in patient selection for therapy, to monitor treatment and to modify or optimize therapeutic regimens. The physiological status of a cell can be determined by comparing the intracellular status of one or more activation elements (e.g. the phosphorylation status of a signaling molecule) in a cell (e.g. a cancer cell) to that of another cell (e.g. a normal cell). The physiological status of a cell can be further classified by adding one or more modulators (e.g. an inhibitor or activator) to the cell in question. In some embodiments, the invention is directed to methods of determining a phenotypic profile of a population of cells.
本发明涉及诊断、预后和确定治疗方法的方法和组合物。样本(如临床样本)中存在的细胞的生理状态可用于诊断或预后病情(如慢性淋巴细胞白血病)、选择患者进行治疗、监测治疗以及修改或优化治疗方案。细胞的生理状态可通过比较一个细胞(如癌细胞)与另一个细胞(如正常细胞)的一个或多个激活元件的胞内状态(如信号分子的
磷酸化状态)来确定。在相关细胞中加入一种或多种调节剂(如
抑制剂或激活剂),可进一步对细胞的生理状态进行分类。在某些实施方案中,本发明涉及确定细胞群表型特征的方法。
