Alternative splicing enables the regulated generation of multiple mRNA and protein products from a single gene. This Review outlines the splicing process and its alterations in cancer before highlighting related opportunities for the development of innovative therapeutic approaches.
Mutations in genes encoding subunits of the SWI/SNF chromatin-remodelling complexes occur in almost 25% of all cancers. Herein, Mittal and Roberts discuss the mechanisms by which these mutations might promote cancer and describe the associated vulnerabilities that provide opportunities for targeted therapy or immunotherapy with immune-checkpoint inhibitors.
The treatment of immune-related adverse events (irAEs) in patients receiving immune checkpoint inhibitors has mostly been based on adapting therapeutic approaches used in the management of primary autoimmune diseases. The authors of this Review provide an overview of the different cellular and soluble immune factors involved in the pathogenesis of irAEs in order to help clinicians deliver personalized immunopathologically guided treatment to manage these adverse events.
The use of bispecific antibodies to engage cells of the immune system that are cytotoxic to cancer cells is a major focus of cancer immunotherapy, with approvals for the treatment of acute lymphoblastic leukaemia. Here, the authors review the clinical results obtained with bispecific antibodies to date. They also discuss the challenges associated with this therapeutic approach and the proposed solutions aimed at preventing or minimizing toxicities, countering immune escape and broadening the indications for these treatments.
The authors of this Review present the main pathways that regulate apoptosis as well as other signalling pathways that interact with them, highlighting actionable molecular targets for anticancer therapy. They also provide an overview of therapeutic agents exploiting apoptosis currently in clinical translation and known mechanisms of resistance to these agents.
Lineage plasticity is a source of intratumoural heterogeneity and enables tumour adaptation to an adverse tumour microenvironment, eventually leading to therapeutic resistance. The authors of this Review provide an overview of the impact of lineage plasticity on cancer progression and therapy resistance, with a focus on neuroendocrine transformation in lung and prostate tumours, and discuss emerging management strategies and open questions in the field.
Cancer cells, like non-malignant cells, are dependent on folate uptake for growth. However, cancer cells are much more reliant on folate receptors (FRs) and particularly FRα for folate uptake than non-malignant cells. In this Review, the authors describe the available data on the role of FRα as a biomarker and as a target of imaging probes, and of targeted therapies in patients with solid tumours.
TRM cells have a role in peripheral immune surveillance in several organs. The presence of TRM cells in the immune infiltrate is also associated with improved outcomes in patients with several solid tumour types, and these cells might have a role in the response to immune checkpoint inhibitors. In this Review, the authors describe the available date on the role of TRM cells in patients with breast cancer
Brain metastases are a frequent manifestation of several common solid tumour types, including lung cancer, breast cancer and melanoma. Although the presence of brain-metastatic disease continues to be associated with poor outcomes, advances in surgery, radiotherapy and systemic therapies that can permeate the blood–brain barrier are beginning to improve patient outcomes. In this Review, the authors provide an overview of contemporary advances in the management of brain metastases over the past decade.
Patients with small-cell lung cancer (SCLC) have historically received chemotherapy, typically with poor survival outcomes. In the past few years, the combination of immune-checkpoint inhibitors (ICIs) with chemotherapy has provided a more effective alternative to chemotherapy alone. Nonetheless, durations of survival are often short, and no robust biomarkers of response are available. In this Review, the authors provide a summary of the efficacy and safety of ICIs in patients with SCLC, and also highlight potential novel immunotherapeutic approaches that are currently in the early stages of investigation.
