This method addresses the challenge of isolating target clones from heterogeneous populations, enhancing the analysis of clone dynamics and transcriptomic landscapes. Additionally, the development of RNA-linked CRISPR screening, termed ReLiC, facilitates the measurement of RNA metabolic processes in response to the knockout of over 2,000 human genes, showcasing the scalability and high-throughput capabilities of this approach (ref: Nugent doi.org/10.1038/s41592-025-02702-6/). Furthermore, barcoded CRISPR screens have revealed intricate RNA regulatory networks, highlighting the interplay between synthetic and endogenous coding sequences in human cells (ref: Unknown doi.org/10.1038/s41592-025-02703-5/). Base editing has emerged as a promising therapeutic strategy, particularly for trinucleotide repeat diseases such as Huntington's disease and Friedreich's ataxia. Studies demonstrate that base editing can effectively reduce somatic repeat expansions in patient-derived cells and animal models, providing a potential pathway for therapeutic intervention (ref: Matuszek doi.org/10.1038/s41588-025-02172-8/).

Cancer therapy resistance remains a significant challenge, with recent studies uncovering the role of genetic alterations in mediating resistance mechanisms. For instance, APOBEC3 mutagenesis has been identified as a frequent driver of therapy resistance in breast cancer, leading to characteristic alterations such as RB1 loss (ref: Gupta doi.org/10.1038/s41588-025-02187-1/). This finding highlights the potential of APOBEC3 as a biomarker for predicting therapeutic outcomes and guiding treatment strategies. Moreover, the impact of poly(ADP-ribose) polymerase inhibitors (PARPis) on T cell DNA damage has been explored, revealing that sustained DNA damage during treatment can diminish antitumor efficacy (ref: Liu doi.org/10.1126/scitranslmed.adr5861/). This underscores the necessity of understanding the immune response in conjunction with therapeutic strategies to enhance treatment effectiveness. Additionally, transcriptional remodeling has been shown to shape therapeutic vulnerability to necroptosis in acute lymphoblastic leukemia, suggesting alternative pathways for overcoming apoptosis resistance (ref: Saorin doi.org/10.1182/blood.2025028938/). Collectively, these insights into cancer biology and therapeutic resistance mechanisms pave the way for developing more effective treatment modalities.
