| Open AccessBone marrow stromal cells induce chromatin remodeling in multiple myeloma cells leading to transcriptional changes
Bone marrow stromal cells (BMSCs) are known to promote the development of drug resistance. Here, the authors investigate the chromatin remodeling and associated changes in gene expression in the multiple myeloma (MM) cells following their interactions with BMSCs, which are also observed in extramedullary disease (EMD).

| Open AccessCEA-CD3 bispecific antibody cibisatamab with or without atezolizumab in patients with CEA-positive solid tumours: results of two multi-institutional Phase 1 trials
Cibisatamab is a T-cell bispecific antibody targeting the carcinoembryonic antigen (CEA) on tumor cells and CD3 epsilon chain on T cells. Here the authors report the results of two clinical trials of cibisatamab as monotherapy (NCT02324257) and in combination with atezolizumab (anti-PD-L1; NCT02650713) in patients with CEA-positive solid tumors.

| Open AccessProteostatic reactivation of the developmental transcription factor TBX3 drives BRAF/MAPK-mediated tumorigenesis
MAPK-driven tumorigenesis is often related to epithelial dedifferentiation but the regulatory mechanism is less clear. Here, the authors show that MAPK activation upregulates USP15 to promote deubiquitylation and stability of TBX3, a transcription factor implicated in thyroid development and differentiation, driving tumorigenesis in a BRAFV600E thyroid tumor model.

The use of oncolytic viruses as a therapy for cancer is limited by mechanisms inhibiting viral replication in the tumor. Here, the authors show that a chemical derivative of itaconate, 4-octyl itaconate, increases oncolytic virus VSVΔ51 efficacy in various cancer models, through decreasing antiviral immunity.

| Open AccessPD-1/CD80+ small extracellular vesicles from immunocytes induce cold tumours featured with enhanced adaptive immunosuppression
Immune checkpoint inhibition is a successful form of immune therapy; however response rates vary widely among individual patients. Here authors show that circulating small extracellular vesicles might contribute to poor response to anti-PD-1 treatment by carrying PD-1 and CD80 which results in higher level of vesicular PD-L1 expression in the circulation at the expense of expression on tumour cell membranes, causing immunosuppression.
