Merkel cell carcinoma (MCC) is a rare aggressive skin cancer with limited therapeutic options. In this work, the authors identify aurora kinase B (AURKB) as a critical therapeutic target for MCC, supported by tumour shrinkage and increased survival when using the AURKB inhibitor AZD2811 nanoparticle formulation in MCC preclinical models.

Federated learning (FL) algorithms have emerged as a promising solution to train models for healthcare imaging across institutions while preserving privacy. Here, the authors describe the Federated Tumor Segmentation (FeTS) challenge for the decentralised benchmarking of FL algorithms and evaluation of Healthcare AI algorithm generalizability in real-world cancer imaging datasets.

An NNMT inhibitor reduces tumour burden and metastasis in multiple mouse cancer models and restores immune checkpoint blockade efficacy by decreasing cancer-associated-fibroblast-mediated recruitment of myeloid-derived suppressor cells and reinvigorating CD8⁺ T cell activation.

Certain antimetabolites used to treat cancer are more neurotoxic than others, and it is now shown that this is due to their greater tendency to generate DNA double-stranded breaks, whereas less neurotoxic agents induce single-stranded breaks.

This work integrates duplex sequencing with cost-effective Ultima sequencing to enhance the accuracy of whole-genome circulating cell-free DNA profiling.

The antiviral protein SP140 negatively regulates Ifnb1 mRNA stability by directly repressing the expression of the immune regulator RESIST.

The advantage of living in cities compared with rural areas with respect to height and BMI in children and adolescents has generally become smaller globally from 1990 to 2020, except in sub-Saharan Africa.

Lu and colleagues show that signaling through the lactate receptor HCAR1 in colorectal tumor cells promotes the recruitment of immunosuppressive CCR2⁺ PMN-MDSCs and that inhibition of HCAR1 by reserpine augments the CD8⁺ T cell-mediated antitumor immune response.

Lewis acid additive semicarbazide hydrochloride improves the formation of α-phase FAPbI₃-based films and promotes a homogeneous vertical distribution of A-site cations through a deprotonation–reprotonation process. The upgraded device performance reaches up to 26.12% with high stability, and mini-module perovskite solar cells achieving 21.47% (area, 11.52 cm²) demonstrate great scalability.

Gorman et al. designed a Lassa virus prefusion-stabilized soluble glycoprotein complex trimer (GPC), with which they identified a Lassa virus-neutralizing nanobody that bound the GPC apex and elicited neutralizing antibody responses in guinea pigs.

Abrupt millennial-scale climate variability, known as Dansgaard-Oeschger (D-O) events, characterized the last glacial. Stalagmite data from northern Türkiye show D-O events for the penultimate glacial period, though they were less frequent.

Analysis of the pivotal phase 3 ZUMA-7 trial identifies tumor gene expression signatures that are uniquely predictive of anti-CD19 CAR T cell response and event-free survival in second-line treatment for patients with relapsed or refractory large B cell lymphoma.

A meta-analysis of genome-wide association studies of type 2 diabetes (T2D) identifies more than 600 T2D-associated loci; integrating physiological trait and single-cell chromatin accessibility data at these loci sheds light on heterogeneity within the T2D phenotype.

Despite being an established oncogenic driver of non-small cell lung cancer (NSCLC), therapies targeting NRF2 hyperactivation are lacking. Here, the authors identify peptidylprolyl isomerase A (PPIA) as a mediator of NRF2 stability and demonstrate the efficacy of targeting this interaction with cyclosporin A in preclinical models of NSCLC.

An alternative HIV vaccine design facilitates generation of HIV-1-antibodies, with promising neutralization breadth in rodents and nonhuman primates.

Transcriptomic, proteomic and immune repertoire profiling reveals distinct peripheral features of MIS-C and pediatric COVID-19, including elevated soluble spike protein levels, more pronounced type II IFN-dependent gene expression and a higher B cell mutation rate in patients with MIS-C.

Toll-like receptor (TLR) signaling activates the transcription factor NF-κB and production of proinflammatory cytokines. O'Neill and colleagues show that TLR signaling induces the microRNA miR-21 to dampen PDCD4 expression, which leads to less NF-κB activity and more IL-10 production.

Accurate molecular representation of compounds is a fundamental challenge for drug discovery. Here, the authors present a molecular video-based foundation model pretrained on 120 million frames of 2 million molecular videos, and apply it to molecular targets and properties prediction.

Predicting the properties of a molecule from its structure with high accuracy is a crucial problem in digital drug design. Instead of sequence features, Zeng and colleagues use an image representation of a large collection of bioactive molecules to pretrain a model that can be fine-tuned on specific property prediction tasks.

The importance of STAT5 tyrosine phosphorylation on T cells has not been investigated in vivo. Here the authors generate STAT5A and STAT5B tyrosine mutant knockin mice and show that Stat5a/b tyrosine is required for maximal IL-2 signaling and CD8 + T cell proliferation.

Although loss of XLF, a classical non-homologous DNA end-joining (NHEJ) repair factor, shows strong effects in non-lymphoid cells, in lymphoid cells its absence has only modest effects on V(D)J recombination. This study now shows that in lymphoid cells, two other repair factors — ATM kinase and histone protein H2AX — have functional redundancy with XLF. Thus, mice deficient in both ATM and XLF have compromised conventional NHEJ, although alternative end-joining is retained. The results hint that the redundant function in end-joining that XLF has with both ATM and H2AX may have to do with an ATM role in chromatin accessibility.

Electronic structure methods are vital, yet they are often too computationally expensive. Here, the authors develop machine learned density matrices to fully represent electronic structures in a computationally cheap and accurate way.

Inbreeding depression has been observed in many different species, but in humans a systematic analysis has been difficult so far. Here, analysing more than 1.3 million individuals, the authors show that a genomic inbreeding coefficient (FROH) is associated with disadvantageous outcomes in 32 out of 100 traits tested.

The Cancer Genome Atlas presents an integrative genome-wide analysis of genetic alterations in 279 head and neck squamous cell carcinomas (HNSCCs), which are classified by human papillomavirus (HPV) status; alterations in EGFR, FGFR, PIK3CA and cyclin-dependent kinases are shown to represent candidate targets for therapeutic intervention in most HNSCCs.

Cell type epigenetic and topographic information of primate brain is lacking. Here, authors identified transcriptional regulatory network, gradient expression pattern and disease vulnerability at cell type level in PFC, M1 and V1 of monkey brain by snRNAseq, snATAC-seq and Stereo-seq.

Doan et al. show that loss of cardiac NAD⁺ is sufficient to drive metabolic derangements, hypertrophic remodeling and lethal arrhythmias in adult mouse hearts, despite maintenance of ejection fraction and bioenergetics.
