Using single-cell and high-dimensional profiling of the immune microenvironment, Vignali and colleagues uncover distinct cell subsets and interactions in human invasive ductal and lobular breast carcinoma, with potential prognostic and therapeutic relevance.

Shi et al. report a sulfonation-dependent vulnerability of liver tumors expressing the sulfotransferase SULT1A1 by showing their sensitivity to the small molecule YC-1 and identifying structurally related compounds that can be modified by SULT1A1.

Turrell et al. show that, in young mice, low-level PDGF-C expression maintains dormancy of disseminated tumor cells, but, in aged or fibrotic lungs, the PDGF-C-high environment promotes proliferation, which can be counteracted with inhibition of PDGFRα or PDGF-C blockade.

Speiser and colleagues review the latest advances in understanding of the biological roles of CD4⁺ T cells in cancer immunology and applications for immunotherapy.

Wu et al. report that IFNγ induces the phase separation of KAT8 and IRF1 into condensates that promote PD-L1 upregulation. They further identify a peptide that blocks KAT8–IRF1 condensates, reducing PD-L1 levels and increasing antitumor immunity.

Adler et al. identify granulocyte-derived lipocalin-2 as a mediator of inflammatory astrocyte activation, which in turn facilitates brain metastasis in breast cancer and melanoma.

Coppé and colleagues define a resistance mechanism to combination BRAF- and EGFR-targeted therapy in BRAF^V600E colorectal cancers that could be overcome in vitro and in vivo by repurposing COX2 inhibitors.

What does the explosion of generative artificial intelligence tools mean for science?

Authorship on a paper gives credit where it is due, but it also comes with responsibilities. Here we discuss our policies and offer advice on best practice.
