In this Tools of the Trade article, Erin Brown describes the development of CytoSPACE, a computational tool that aligns single-cell transcriptomes and spatial transcriptomic data, and highlights its use in identifying spatially resolved cell states in the tumour microenvironment.

In a recent study published in Nature, lactate has been identified as a key player in enhancing DNA repair mechanisms in gastric cancer by promoting lactylation of DNA repair proteins, leading to chemotherapy resistance.

Leighow et al. develop a strategy called the dual-switch selection gene drive platform, which enables the evolutionary dynamics of acquired resistance to be manipulated for therapeutic ends.

Pregnancy involves immune system suppression to protect the fetus, making it a valuable model for understanding cancer immune tolerance. Recently in Cell, Yu et al. identified B7-H4 as a common immune tolerance checkpoint in both tumours and the placenta.

In this Journal Club, Maeng and Ku discuss a study demonstrating that profiling drug responses in patient-derived organoids can identify responders to various therapies.

Circular RNAs, once considered by-products of splicing errors, are now accepted as key players in cancer biology. In this Review, Conn et al. review the functional interactome of circular RNAs in cancer, highlighting their contribution to oncogenesis, their potential as biomarkers and the prospect of leveraging them for novel therapeutics.

Adoptive cell therapies have emerged as promising approaches for the treatment of patients with cancer. Engineering cell therapies to confer resistance to small-molecule therapies, chemotherapies and antibody-based therapies will improve their utility and success. Here, Wellhausen, Baek and colleagues outline the key principles of engineering resistance and potential applications for haematopoietic stem cell transplantation and allogeneic immune cell therapies.

Transient ectopic lymphoid structures known as tertiary lymphoid structures (TLS) have been observed in many solid tumour types. In this Review, Teillaud et al. discuss how these TLS potentially orchestrate immune responses against tumours locally and are positively associated with prognosis and response to immune checkpoint inhibitors. The authors also outline how preclinical studies are highlighting the potential to manipulate the formation and function of TLS as a novel form of immunotherapy.
