  • Tissue protective erythropoietin receptor (nepor) and methods of use
    申请人:Life Biosystems GmbH
    公开号:EP2492355A1
    公开(公告)日:2012-08-29
    There is disclosed a molecular composition(s) of a novel tissue protective erythropoietin (EPO) binding receptor protein complex, termed NEPOR. Presence of NEPOR components on a tumour allows EPO to impinge on the survival of associated cells thereby enhancing tumour progression and negatively effecting patient survival. There is disclosed that presence of NEPOR represents a prognostic biomarker for poorer patient outcome. Thus, the method disclosed is for stratifying patients having a tumour as suitable (i.e. NEPOR not present) or non-suitable (i.e., NEPOR present) for EPO treatment, comprising: (a) isolating a tissue sample from an individual who is receiving or is a candidate for receiving erythropoietin, (b) determining the level of expression of the NEPOR gene(s) (mRNA) and/or the presence of the NEPOR gene product (protein) from the isolated tissue, and (c) correlating the presence of an NEPOR gene expression product or the presence of NEPOR protein to a physiological response to the treatment with erythropoietin. Furthermore, by disclosing the molecular compositions of NEPOR species, there are disclosed methods for rationally identifying/designing NEPOR modulating therapeutics. Thus, the present disclosure provides methods for treating neurological insults such as stroke (via enhancement of NEPOR activity) and cancer (via down-regulation of cyto-protective signaling from NEPOR).
    本发明公开了一种新型组织保护性促红细胞生成素(EPO)结合受体蛋白复合物(称为 NEPOR)的分子组成。肿瘤上 NEPOR 成分的存在可使 EPO 影响相关细胞的存活,从而促进肿瘤的发展并对病人的存活产生负面影响。据披露,NEPOR 的存在是患者预后较差的预后生物标志物。因此,所公开的方法用于将肿瘤患者分层为适合(即不存在 NEPOR)或不适合(即存在 NEPOR)使用 EPO、NEPOR 存在)进行 EPO 治疗,包括:(a) 从正在接受或可能接受促红细胞生成素治疗的个体中分离组织样本;(b) 从分离的组织中确定 NEPOR 基因的表达平(mRNA)和/或 NEPOR 基因产物(蛋白质)的存在;(c) 将 NEPOR 基因表达产物的存在或 NEPOR 蛋白质的存在与促红细胞生成素治疗的生理反应相关联。此外,通过公开 NEPOR 物种的分子组成,还公开了合理鉴定/设计 NEPOR 调节疗法的方法。因此,本公开提供了治疗神经损伤如中风(通过增强 NEPOR 活性)和癌症(通过下调来自 NEPOR 的细胞保护信号)的方法。
