    • Today, despite current advances in combinatorial therapies such as surgery, radiotherapy and chemotherapy, aggressive cancers remain fatal. Cancer stem-like cells (CSCs) may account for chemotherapy resistance and thus represent a promising therapeutic target. In this context, the present inventors identified essential intracellular pathways favoring the self-renewal and survival of CSCs. More precisely, the present inventors showed that the cytokine co-receptor GP130 acts as a co-receptor for Apelin / APJ signaling and that the interaction of Apelin with APJ/GP130 activates a dual signaling pathway involving the Akt/mTOR and STAT3 transcription factor, thereby promoting CSCs survival and self-renewal. They therefore propose to block these pathways in order to treat patients suffering from tumors containing CSCs, such as glioblastomas. In another aspect, the invention relates to the use of the Apelin expression level for evaluating the survival probability of a subject suffering from glioblastoma.
    • 今天,尽管组合治疗如手术,放射治疗和化学疗法目前取得进展,但侵袭性癌症仍然是致命的。 癌症干细胞(CSCs)可以解释化疗耐药性,因此代表着有希望的治疗靶点。 在这方面,本发明人确定了有利于CSC的自我更新和存活的必需的细胞内途径。 更准确地说,本发明人表明细胞因子共受体GP130作为Apelin / APJ信号传导的共同受体,并且Apelin与APJ / GP130的相互作用激活涉及Akt / mTOR和STAT3转录因子的双信号通路, 从而促进CSCs的生存和自我更新。 因此,他们建议阻止这些途径以治疗患有含有CSC的肿瘤的患者,例如成胶质细胞瘤。 另一方面,本发明涉及Apelin表达水平用于评估患有胶质母细胞瘤的受试者的存活概率的用途。
