DLL3在小细胞肺癌中的表达及其在靶向治疗中的应用

Expression of DLL3 in small cell lung cancer and its application in targeted therapy

小细胞肺癌(SCLC)生物学行为恶劣,复发转移概率高,治疗手段有限.Notch信号传导通路是一种进化保守途径,可通过局部细胞-细胞相互作用来调控多种类型细胞的生长,其可调控细胞的分化、增殖和存活.Delta样蛋白3(DLL3)作为Notch通路的配体,特异性高表达于SCLC细胞表面.DLL3在SCLC的肿瘤启动和上皮-间质转化、侵袭和转移中扮演着重要的角色.Rovalpituzumab tesirine是一种靶向DLL3抗体的药物偶联物,在SCLC治疗方面具有巨大的潜力.

Small cell lung cancer (SCLC) has a poor biological behavior,high probability of recurrence and metastasis,and limited treatment.The Notch signaling pathway is an evolutionarily conserved pathway that regulates the growth of many cell types through local cell-cell interactions.It controls the differentiation,proliferation and survival of cells.As a ligand for the Notch pathway,delta-like protein 3 (DLL3) is highly expressed on the membrane of SCLC cells.DLL3 plays an important role in cancer initiation and epithelial mesenchymal transition,invasion and metastasis of SCLC.Rovalpituzumab tesirine is a conjugate of directed against DLL3,which shows great potential for SCLC therapy.
