More than half of the human protein-coding genes display alternative polyadenylation (APA), whereby 3'-end processing of the nascent RNA takes place at different sites. APA leads to mRNA isoforms containing different 3' untranslated regions (3'UTRs), which generally modulate mRNA metabolism in cis but can also exert cellular functions in trans. In addition, intronic APA alters protein sequences at the carboxy-terminal region or inhibits gene expression through premature transcription termination. APA is increasingly recognized as a key layer of transcriptomic regulation that defines cell identity and proliferation and/or differentiation states, as well as controlling cellular responses to environmental cues. The relevance of APA for human health is highlighted by the many pathological conditions that are associated with APA dysregulation, including cancer, developmental disorders and neurodegeneration, as well as the disease risks associated with a growing number of genetic variations shown to affect APA. Here, we discuss physiological and pathological APA dynamics, the human mutations and genetic variants that are associated with changes in APA, and our current understanding of the functional effects and regulatory mechanisms of APA.

CRISPR-based genome editing therapeutics are entering the clinic, offering transformative potential but also presenting potential risks. Preclinical-to-clinical toolkits are needed to assess the safety and efficacy of these new therapies and accelerate progress. Emerging technologies to monitor the biological effects of genome editors cover a range of biological scales, from the direct measurement of editing outcomes in DNA, to human microphysiological systems, and non-invasive in vivo imaging. Measurements of on-target and off-target editing outcomes, including sequences unique to humans, provide essential benchmarks to understand functional responses. Microphysiological systems, including organoids and organs-on-chips, enable phenotypic evaluations of editing strategies in varied organ lineages and disease states. Non-invasive imaging modalities can track the biodistribution and activities of genome editors and edited cells in vivo. Collectively, these technologies provide complementary insights across different scales, from the single nucleotide to the whole organism, bridging preclinical therapeutics development with clinical trials.

Proteoforms are the diverse molecular protein species produced from a single gene through genetic variation, alternative splicing and post-translational modifications. They are the crucial link between genotype and phenotype. There are estimated to be more than one million distinct protein variants produced from ~20,000 protein-coding genes in a given cell, making these proteoforms a vast and largely uncharacterized dimension in biomedical research. This Review focuses on the role of proteoforms in human genetic diseases. We highlight cutting-edge technologies for the identification and characterization of proteoforms, including long-read transcriptomics and emerging methods for direct protein sequencing, and we present a network biology framework to explain how proteoforms can perturb the molecular interactions and cellular pathways underlying disease phenotypes. We believe that precision medicine will require precision proteomics. An increasing knowledge of proteoform biology from molecular, systems and clinical perspectives will guide future research, ultimately contributing to a more precise understanding of the molecular basis of disease and refined therapeutic interventions.

Single-cell analyses have transitioned from descriptive atlasing towards inferring causal effects and mechanistic relationships that capture cellular logic. Technological advances and the growing scale of observational and interventional datasets have fuelled the development of machine learning methods aimed at identifying such dependencies and extrapolating perturbation effects. Here, we review and connect these approaches according to their modelling concepts (including representation learning, causal inference, mechanistic discovery, disentanglement and population tracing), underlying assumptions and downstream tasks. We propose a unifying ontology to guide practitioners in selecting the most suitable methods for a given biological question, with detailed technical descriptions provided in an online resource . Finally, we identify promising computational directions and underexplored data properties that could pave the way for future developments.
