Abstract

Cancer is a complex disease characterized by genetic and molecular diversity, often involving dysregulation of critical cellular pathways. Recent advances in pan-cancer research have highlighted the importance of shared oncogenic mechanisms across different cancer types, providing new avenues for therapeutic exploration. Protein kinases, particularly those involved in phagocytosis, play pivotal roles in cellular homeostasis and immune response. This study systematically examines the genetic alterations and expression profiles of protein kinases associated with phagocytosis across various cancer types, using data from The Cancer Genome Atlas (TCGA) and other publicly available resources. We analyzed single nucleotide variations (SNVs), copy number variations (CNVs), methylation patterns, and mRNA expression to identify recurring alterations and their associations with survival outcomes. Our findings reveal that MET and MERTK are the most frequently mutated genes, with missense mutations dominating across cancers. CNV analysis shows significant correlations with survival in cancers like UCEC, KIRP, and KIRC, while methylation analysis indicates cancer-specific regulatory patterns affecting gene expression. Differential expression analysis highlights distinct cancer-type-specific expression profiles, with genes like MET and BTK displaying significant variation. Crosstalk pathway analysis further reveals the involvement of these kinases in key cancer-related pathways, such as epithelial-mesenchymal transition (EMT) and apoptosis. Drug sensitivity analysis identifies potential therapeutic targets, with gene expression correlating significantly with cancer cell line responsiveness to specific compounds. These findings underscore the importance of the phagocytotic kinome in cancer biology and suggest potential therapeutic strategies targeting protein kinases to enhance immune response and improve treatment outcomes.

Generation of a transgenic cephalopod

Coleoid cephalopods (cuttlefish, octopus, and squid) are marine mollusks with elaborate nervous systems that support a diverse repertoire of complex behaviors. These include the neural control of the color, pattern, and texture of the skin, facilitating both adaptive camouflage and innate patterning that may reflect internal state. The development of transgenic cephalopods expressing fluorescent proteins, optogenetic actuators, and reporters of neural activity would contribute a new and important technology to cephalopod biology. The generation of transgenic cephalopods, however, has remained a major challenge. Here, we report the development of stable transgenic dwarf cuttlefish (Ascarosepion bandense) expressing ubiquitous nuclear-localized mScarlet, a red fluorescent protein. We evaluated multiple strategies for transgenesis, and established cuttlefish lines using both CRISPR and the transposons Sleeping Beauty and Minos. The stable expression of transgenes enabled live imaging of cell dynamics during embryonic development. The Minos transposon emerged as the most efficient transgenesis strategy and is adaptable to promoters and transgenes of choice. These strategies now enable the generation of diverse genetic tools for mechanistic studies of cephalopod biology.

Large language model-based bibliometric evaluation of population descriptors in human genetics

As the use of population descriptors such as race, ethnicity, and ancestry have become increasingly common in modern genetics research, there have been growing calls to critically examine their use. Most notably, in 2023, the National Academies of Science, Engineering, and Medicine (NASEM) published a report titled Using Population Descriptors in Genetics and Genomics Research: A New Framework for an Evolving Field, which included eight specific and actionable recommendations for researchers to implement the ethical and accurate use of population descriptors in genetic research. Here, we use the 2023 NASEM report as a benchmark to analyze the use of population descriptors in genome-wide association studies (GWAS). We develop a general toolkit for large language model-based bibliometrics, operationalize the report's recommendations into an evaluation framework, and apply this framework to evaluate all 4,007 papers from the GWAS Catalog published between 2007 and 2025 with full text available on PubMedCentral. We find significant improvements in adherence to NASEM report recommendations over time. However, most improvements predate the publication of the NASEM report itself, suggesting the report functioned primarily as a synthesis of existing best practices rather than a catalyst for change. We conclude by highlighting opportunities for growth in the field of human genetics.

Mitigating biases of rescaling in forward-in-time population genetic simulations

Forward-in-time population genetic simulations are widely used in evolutionary analyses, but simulating large populations and long genomic regions remains computationally demanding. To reduce this cost, parameter rescaling is widely employed, in which the original evolutionary process is approximated by one with a smaller population size and fewer generations. Recently, several studies using the SLiM simulator have raised concerns about the accuracy of this rescaling approach. In this study, we show that many of the biases reported in these studies can be mitigated by using a different simulation algorithm. These results reveal that the accuracy of parameter rescaling depends on how well the simulation algorithm preserves diffusion-limit properties under rescaling.
