Cellular stress induced by obesity is a critical factor in cancer predisposition and is also a driver of the disease. Stress granules (SG), a type of phase-separation non-membranous organelle, have been identified as KRAS-dependent mediators of stress adaptation in pancreatic ductal adenocarcinoma (PDAC), but their requirement in tumorigenesis has yet to be determined. Fonteneau and colleagues showed that obesity-associated PDAC is supported by SGs in a murine model of PDAC. Mechanistically, SG formation was mediated through the serine/arginine protein kinase 2 (SRPK2), which is driven through hyperactivation of the IGF1/PI3K/mTOR/S6K1 signaling pathway. Moreover, inhibition of S6K1 impaired SG formation as well as subsequent obesity-associated development of PDAC, suggesting that SGs are a driving force behind obesity-associated PDAC formation and can be a potential chemopreventive target for this disease.

Elevated Mutational Age in Blood of Children Treated for Cancer Contributes to Therapy-Related Myeloid Neoplasms
Chemotherapy increases the mutation burden of normal blood cells in childhood cancer survivors by direct treatment-induced mutagenesis and enhanced activity of processes that are also present during healthy aging.
Human Colon Cancer–Derived Clostridioides difficile Strains Drive Colonic Tumorigenesis in Mice
The patient-derived Clostridioides difficile bacterial strain was found to drive colon tumorigenesis through its toxin TcdB, which induced Wnt signaling and a protumorigenic mucosal immune response.

Sequential Single-Cell Transcriptional and Protein Marker Profiling Reveals TIGIT as a Marker of CD19 CAR-T Cell Dysfunction in Patients with Non-Hodgkin Lymphoma
Single-cell analysis of pre- and postinfusion CD19 CAR-T cells from patients with lymphoma reveals TIGIT as a mediator of CAR-T cell dysfunction that may be alleviated by TIGIT antibody blockade in mouse models of human lymphoma.
Tumor-Derived Lysophosphatidic Acid Blunts Protective Type I Interferon Responses in Ovarian Cancer
Controlling lysophosphatidic acid production in the tumor microenvironment sensitizes ovarian cancer cells to various forms of immunotherapy by unleashing protective type I interferon responses.
BCL10 Mutations Define Distinct Dependencies Guiding Precision Therapy for DLBCL
BCL10 mutations in diffuse large B-cell lymphoma (DLBCL) fall into two classes, with both conferring BTK inhibitor resistance but only truncation mutations conferring MALT1 dependency, suggesting use of these mutation classes as precision therapy biomarkers.
Enhancing PD-L1 Degradation by ITCH during MAPK Inhibitor Therapy Suppresses Acquired Resistance
A small-molecule approach to degrade tumor cell–surface PD-L1 overcomes adaptive immune resistance during MAPK inhibitor therapy, showcasing control of PD-L1 protein stability as an emerging combinatorial strategy.
IL27 Signaling Serves as an Immunologic Checkpoint for Innate Cytotoxic Cells to Promote Hepatocellular Carcinoma
IL27R signaling suppresses cytotoxic mechanisms in liver cancer, while inhibition of IL27 or IL27R enhances the activation of innate cytotoxic cells leading to anticancer immunity and supporting novel immunotherapeutic applications in hepatocellular carcinoma.
Stress Granules Determine the Development of Obesity-Associated Pancreatic Cancer
Stress granules (SG) impact obesity-associated pancreatic cancer growth, and targeting the IGF1/IGF1R/S6K1/SRPK2 signaling pathway, which drives SG formation in obesity-associated pancreatic cancer, can selectively impair SGs and tumor growth.
