The HER3 protein, that belongs to the ErbB/HER receptor tyrosine kinase (RTK) family, is expressed in several types of tumors. That fact, together with the role of HER3 in promoting cell proliferation, implicate that targeting HER3 may have therapeutic relevance. Furthermore, expression and activation of HER3 has been linked to resistance to drugs that target other HER receptors such as agents that act on EGFR or HER2. In addition, HER3 has been associated to resistance to some chemotherapeutic drugs. Because of those circumstances, efforts to develop and test agents targeting HER3 have been carried out. Two types of agents targeting HER3 have been developed. The most abundant are antibodies or engineered antibody derivatives that specifically recognize the extracellular region of HER3. In addition, the use of aptamers specifically interacting with HER3, vaccines or HER3-targeting siRNAs have also been developed. Here we discuss the state of the art of the preclinical and clinical development of drugs aimed at targeting HER3 with therapeutic purposes.
HER3 蛋白属于表皮生长因子受体家族(ErbB/HER receptor tyrosine kinase,RTK),在多种类型的肿瘤中表达。这一事实,以及 HER3 在促进细胞增殖中的作用,表明针对 HER3 可能具有治疗相关性。此外,HER3 的表达和激活与对其他 HER 受体靶向药物的耐药性有关,如针对 EGFR 或 HER2 的药物。此外,HER3 与一些化疗药物的耐药性有关。由于这些情况,已经进行了开发和测试针对 HER3 的药物的努力。已经开发了两种针对 HER3 的药物类型。最常见的是抗体或工程抗体衍生物,它们特异性地识别 HER3 的细胞外区域。此外,还开发了与 HER3 特异性相互作用的适体、疫苗或 HER3 靶向 siRNA。在这里,我们讨论了以治疗为目的针对 HER3 的药物的临床前和临床开发的最新进展。
