弥漫性大B细胞淋巴瘤(DLBCL)是最常见的非霍奇金淋巴瘤。R-CHOP是目前治疗DLBCL的标准治疗方法,但难治性或复发性患者的预后仍然很差。在本研究中,我们合成了一种新型的水溶性抗疟疾药物青蒿素衍生物SM1044。SM1044可诱导DLBCL细胞发生自噬依赖性的细胞凋亡,其机制是通过抗凋亡蛋白Survivin与自噬相关蛋白LC3-II的乙酰化相互作用而加速降解。此外,SM1044还刺激神经酰胺的从头合成,进而激活CAMK2-AMPK-ULK1轴,从而启动自噬。我们的发现不仅阐明了DLBCL细胞自噬依赖性凋亡的机制,而且提示SM1044与R-CHOP方案一样,是治疗DLBCL的有前途的治疗分子。
Diffuse large B‐cell lymphoma (DLBCL) is the most common form of non‐Hodgkin's lymphoma. R‐CHOP is currently the standard therapy for DLBCL, but the prognosis of refractory or recurrent patients remains poor. In this study, we synthesized a new water‐soluble antimalarial drug artemisinin derivative, SM1044. The treatment of DLBCL cell lines with SM1044 induces autophagy‐dependent apoptosis, which is directed by an accelerated degradation of the antiapoptosis protein Survivin, via its acetylation‐dependent interaction with the autophagy‐related protein LC3‐II. Additionally, SM1044 also stimulates the de novo synthesis of ceramide, which in turn activates the CaMKK2–AMPK–ULK1 axis, leading to the initiation of autophagy. Our findings not only elucidate the mechanism of autophagy‐dependent apoptosis in DLBCL cells, but also suggest that SM1044 is a promising therapeutic molecule for the treatment of DLBCL, along with R‐CHOP regimen.
