BCMA-specific chimeric antigen receptor-T cells (CAR-Ts) have exhibited remarkable efficacy in refractory or relapsed multiple myeloma (RRMM); however, primary resistance and relapse exist with single-target immunotherapy. Bispecific CARs are proposed to mitigate these limitations.We constructed a humanized bispecific BM38 CAR targeting BCMA CD38 tested the antimyeloma activity of CAR-Ts vitro vivo. Twenty-three patients RRMM received infusions phase I trial.BM38 showed stronger cytotoxicity...

Abstract Pyroptosis is a form of programmed cell death (PCD) that plays vital role in immunity and diseases. Although it was recently reported chemotherapy drugs can induce pyroptosis through caspase‐3‐dependent cleavage gasdermin E (GSDME), the osteosarcoma (OS) with dioscin less understood. In this study, we explored effects on OS vitro vivo further elucidated underlying molecular mechanisms found dioscin‐triggered GSDME‐dependent GSDME‐N generated by caspase‐3. Furthermore, inhibited...

Inherent or acquired resistance to chemotherapeutic drugs is still an obstacle for the treatment of multiple myeloma (MM). MicroRNA dysregulation related development chemoresistance in cancers. However, its role MM largely unknown. Here we demonstrated that miR-221/222 were upregulated plasma cells from patients with MM, especially those relapsed refractory disease. Moreover, expression levels inversely correlated dexamethasone (Dex) sensitivity human cell lines. Importantly, found Dex...

N6-methyladenosine (m6A), as the most pervasive internal modification of eukaryotic mRNA, plays a crucial role in various cancers, but its multiple myeloma (MM) pathogenesis has not yet been investigated. In this study, we revealed significantly decreased m6A methylation plasma cells (PCs) from MM patients and showed that abnormal level resulted mainly upregulation demethylase fat mass obesity-associated protein (FTO). Gain- loss-of-function studies demonstrated FTO tumor-promoting...
