ZIC1 is a context-dependent medulloblastoma driver in the rhombic lip.

Nat Genet

January 2025

Department of Laboratory Medicine and Pathobiology, University of Toronto, Toronto, Ontario, Canada.

Transcription factors are frequent cancer driver genes, exhibiting noted specificity based on the precise cell of origin. We demonstrate that ZIC1 exhibits loss-of-function (LOF) somatic events in group 4 (G4) medulloblastoma through recurrent point mutations, subchromosomal deletions and mono-allelic epigenetic repression (60% of G4 medulloblastoma). In contrast, highly similar SHH medulloblastoma exhibits distinct and diametrically opposed gain-of-function mutations and copy number gains (20% of SHH medulloblastoma).

Human cancer cell lines are the mainstay of cancer research. Recent reports showed that highly mutated adult carcinoma cell lines (mainly HeLa and MCF-7) present striking diversity across laboratories and that long-term continuous culturing results in genomic/transcriptomic heterogeneity with strong phenotypical implications. Here, we hypothesize that oligomutated pediatric sarcoma cell lines mainly driven by a fusion transcription factor, such as Ewing sarcoma (EwS), are genetically and phenotypically more stable than the previously investigated adult carcinoma cell lines.

Epstein-Barr nuclear antigen 1 (EBNA1), a sequence-specific DNA binding protein of Epstein-Barr virus (EBV), is essential for viral genome replication and maintenance and is therefore an attractive target for the therapeutic intervention of EBV-associated cancers. Several EBNA1-specific inhibitors have demonstrated the ability to block EBNA1 function in vitro, but practical delivery strategies for these inhibitors in vivo are still lacking. Here, we report an intelligent hierarchical targeting theranostic nanosystem (denoted as mZGOCS@MnO-P5) that integrates an azide (N3) terminal dual-targeting peptide (N3-P5), a tumor microenvironment-responsive degradable MnO nanosheet, and a mesoporous ZnGaO:Cr, Sn near-infrared persistent luminescence (NIR-PL) nanosphere (mZGOCS).

The Replicability Crisis and Human Agency in the Neo-Structured World.

Integr Psychol Behav Sci

January 2025

Department of Psychology, St. Petersburg State University, St. Petersburg, Russian Federation.

The paper analyzes current discussions concerning the so called "replicability crisis" - a notion describing difficulties in attempts to confirm existing research findings by their additional scrutiny or by new empirical studies. We propose interpretation that this "crisis" may be seen as a manifestation of the increasing inconsistency between, on the one hand, the outdated views on a human being and social structures dominating in the academic mainstream across various disciplines, including psychology and sociology, and, on the other hand, the reality of the emerging new stage of societal evolution, neo-structuration, which brings to the forefront individual agency. Our analysis suggests the possibilities for the future inter-disciplinary paradigmatic shift, which implies putting in the center of research not the idea of a constant or predictably developing individual in the context of solid external structures operating in line with a presumably sustainable "progress".

Reinforcement Learning Optimization of the Charging of a Dicke Quantum Battery.

Phys Rev Lett

December 2024

Freie Universität Berlin, Department of Mathematics and Computer Science, Arnimallee 6, 14195 Berlin, Germany.

Quantum batteries are energy-storing devices, governed by quantum mechanics, that promise high charging performance thanks to collective effects. Because of its experimental feasibility, the Dicke battery-which comprises N two-level systems coupled to a common photon mode-is one of the most promising designs for quantum batteries. However, the chaotic nature of the model severely hinders the extractable energy (ergotropy).

Introduction: Professional caregivers (nursing assistants and personal care aides) in nursing homes (NH) and assisted living (AL) provide the majority of long-term residential care for persons with Alzheimer's disease and related dementias. Their work is stressful, but until recently, no measures were available to assess stress in this workforce. Using the new Long-Term Care Cope (LTC COPE) scale, this study evaluates the relationship of coping with staff demographic characteristics and outcomes; the findings can be used to develop and evaluate interventions to improve staff well-being.

Complex multicellular organisms are composed of distinct tissues involving specialized cells that can perform specific functions, making such life forms possible. Species are defined by their genomes, and differences between individuals within a given species directly result from variations in their genetic codes. While genetic alterations can give rise to disease-causing acquisitions of distinct cell identities, it is now well-established that biochemical imbalances within a cell can also lead to cellular dysfunction and diseases.

Behavioral copying is a key process in group actions, but it is challenging for individuals with autism spectrum disorder (ASD). We investigated behavioral contagion, or instinctual replication of behaviors, in Krushinky-Molodkina (KM) rats ( = 16), a new potential rodent model for ASD, compared to control Wistar rats ( = 15). A randomly chosen healthy Wistar male ("demonstrator rat") was introduced to the homecage of experimental rats ("observers") 10-14 days before the experiments to become a member of the group.

Quality control procedures play a pivotal role in ensuring the reliability and consistency of data generated in mass spectrometry-based proteomics laboratories. However, the lack of standardized quality control practices across laboratories poses challenges for data comparability and reproducibility. In response, we conducted a harmonization study within proteomics laboratories of the Core for Life alliance with the aim of establishing a common quality control framework, which facilitates comprehensive quality assessment and identification of potential sources of performance drift.

Centromeres are essential for chromosome segregation in eukaryotes, yet their specification is unexpectedly diverse among species and can involve major transitions such as those from localized to chromosome-wide centromeres between monocentric and holocentric species. How this diversity evolves remains elusive. We discovered within-cell variation in the recruitment of the major centromere protein CenH3, reminiscent of variation typically observed among species.

Cyclin switch tailors a cell cycle variant to orchestrate multiciliogenesis.

Cell Rep

December 2024

Institut de Biologie de l'ENS (IBENS), CNRS, INSERM, École Normale Supérieure, PSL Research University, Paris, France. Electronic address:

Meiosis, endoreplication, and asynthetic fissions are variations of the canonical cell cycle where either replication or mitotic divisions are muted. Here, we identify a cell cycle variantconserved across organs and mammals, where both replication and mitosis are muted, and that orchestrates the differentiation of post-mitotic progenitors into multiciliated cells (MCCs). MCC progenitors reactivate most of the cell cycle transcriptional program but replace the temporal expression of cyclins E2 and A2 with non-canonical cyclins O and A1.

Cell Rep

December 2024

Institut de Biologie de l'ENS (IBENS), CNRS, INSERM, Ecole Normale Supérieure, PSL Research University, Paris, France. Electronic address:

Multiciliated cells (MCCs) ensure fluid circulation in various organs. Their differentiation is marked by the amplification of cilia-nucleating centrioles, driven by a genuine cell-cycle variant, which is characterized by wave-like expression of canonical and non-canonical cyclins such as Cyclin O (CCNO). Patients with CCNO mutations exhibit a subtype of primary ciliary dyskinesia called reduced generation of motile cilia (RGMC).
