The authors present a potentially useful approach of broad interest arguing that anterior cingulate cortex (ACC) tracks option values in decisions involving delayed rewards. The authors introduce the idea of a resource-based cognitive effort signal in ACC ensembles and link ACC theta oscillations to a resistance-based strategy. The evidence supporting these new ideas is incomplete and would benefit from additional detail and more rigorous analyses and computational methods.

Working with a diverse panel of field-grown rice accessions, this valuable study measures changes in transcript abundance, tests for patterns of selection on gene expression, and maps the genetic basis of variation in gene expression in normal and high salinity conditions. The authors provide solid evidence that salinity treatment increases the number of genes with mean expression levels away from the optimum, and that a relatively small number of genes are hotspots for genetic variants that affect genome-wide patterns of variation in gene expression under high salinity. The design, clarity, and interpretation of several statistical analyses can be improved, additional opportunities for integration among datasets and analyses could be realized, and genetic manipulation would be required to confirm the functional involvement of any specific genes in regulatory networks or organismal traits that confer adaptation to higher salinity conditions. The manuscript will not only be of interest to evolutionary biologists studying the genetics of complex traits, but it will also be a resource for plant biologists studying mechanisms of abiotic stress tolerance.

This study provides a valuable characterization of individual sarcomere's contractility and synchrony in spontaneously beating cardiomyocytes as a function of substrate stiffness. The authors, however, provide an incomplete explanation for the observed heterogeneous and stochastic dynamics, so that the work remains mainly descriptive. The work will be of interest to scientists working on muscle biophysics, nonlinear dynamics, and synchronization phenomena in biological systems.

This study demonstrates a novel role for SIRT4; a mitochondrial deacetylase, shown to translocate into nuclei where it regulates RNA alternative splicing by modulating U2AF2 and the gene expression of CCN2 in tubular cells in response to TGF-β. This fundamental work substantially advances our understanding of kidney fibrosis development and offers a potential therapeutic approach. The evidence supporting the conclusions of a SIRT4-U2AF2-CCN2 axis activated by TGF-β is compelling and adds a new layer of complexity to the pathogenesis of chronic kidney disease.

Zhao et al. report valuable adverse effects on cell proliferation, differentiation and gene expression, possibly linked to reduced binding activity of the transcription factor GTF2IRD1 to the transthyretin (TTR) promoter, in a human forebrain organoid model of Williams Syndrome (WS). The authors provide incomplete evidence of the effects of GTF2IRD1, a mutated gene in WS, on altering MAPK/ERK pathway activity, a well-recognized target in cell proliferation.

eLife assessment

This study provides new insights into the expression profile of ILCs that demonstrate a history of RAG expression. It examines in part the potential intrinsic regulation of RAG expression and seeks to understand how the epigenetic state of ILCs is established, although a full understanding of intrinsic factors is incomplete. The work provides an important molecular dataset, and with further strengthening of the understanding of intrinsic regulation, this paper would be of interest more broadly to cell biologists seeking to understand immune cell development.

eLife assessment

This is a useful study on sex differences in gene expression across organs of four mice taxa, although there are some shortcomings in the data analyses and interpretations that should to be better placed in the broader context of the current literature. Hence, the evidence in the current form is incomplete, with several overstated key conclusions.

eLife assessment

This paper provides valuable findings related to the impact and timing of exogenous interleukin 2 on the balance of exhausted (Tex) versus effector (Teff) that differentiate from precursors T cells (Tpex) during chronic viral infection. While the data appear solid, the overall claims that IL-2 suppresses Tpex are only partially supported, with the rationale for the timing of IL-2 treatment and its underlying mechanisms remaining unclear.

eLife assessment

This important study reports the molecular function of the SARS-CoV-2 helicase NSP13, which inhibits the transcriptional activity of the YAP/TEAD complex in vitro and in vivo. The evidence supporting the authors' claims is solid, with rigorous cell biological assays and multi-omic studies. This work will be of interest to scientists studying COVID-19 infection and the Hippo-YAP signaling pathway.

eLife assessment

This is a useful manuscript describing the competitive binding between Parkin domains to define the importance of dimerization in the mechanism of Parkin regulation and catalytic activity. The evidence supporting the importance of Parkin dimerization for an 'in trans' model of Parkin activity described in this manuscript is solid, but lacks more stringent and biochemical characterization of competitive binding that could provide more direct evidence to support the author's conclusions. This work will be of interest to those focused on defining the molecular mechanisms involved in ubiquitin ligase interactions, PINK-Parkin-mediated mitophagy, and mitochondrial organellar quality control.

eLife assessment

This study provides compelling data that defines the structure of the S. cerevisiae APC/C. The structure reveals overall conservation of its mechanism of action compared to the human APC/C but some important differences that indicate that activation by co-activator binding and phosphorylation are not identical to the human APC/C. Thus this study will be of considerable value to the field.

eLife assessment

This valuable study demonstrates that AARS2 is crucial for protecting cardiomyocytes from ischemic stress by shifting energy metabolism towards glycolysis through PKM2, presenting a novel therapeutic target for myocardial infarction. The findings are supported by solid evidence, including cardiomyocyte-specific genetic modifications, functional assays, and ribosome profiling, which together robustly validate the AARS2-PKM2 signaling pathway's role in cardiac protection.

eLife assessment

This valuable study investigates how the human brain flexibly adjusts its representations of the world as the environment continually changes. It utilizes a unique dataset in which participants view thousands of natural scenes across many fMRI sessions over multiple months. The evidence supporting the claims of the authors is incomplete, with statistical inference not always warranted. The study would interest a broad readership in cognitive neuroscience.

Cav2 voltage-gated calcium channels play key roles in regulating synaptic strength and plasticity. In contrast to mammals, invertebrates like Drosophila encode a single Cav2 channel, raising questions on how diversity in Cav2 is achieved from a single gene. Here, the authors present convincing evidence that two alternatively spliced isoforms of the Cac gene (cacophony, also known as Dmca1A and nightblindA) enable diverse changes in Cav2 expression, localization, and function in synaptic transmission and plasticity. These valuable findings will be of interest to a variety of researchers.

eLife assessment

This study assessed the virulence and immune responses of different M. tuberculosis lineages using a 3D in vitro granuloma model. The useful findings support the functional impact of M. tuberculosis natural diversity on host-pathogen interactions but are incomplete and only partially support the claims. The study will interest researchers working on mycobacteria and understanding how genetic diversity influences virulence and immunity outcomes.

eLife assessment

The study is a valuable contribution to the question of evolutionary shifts in neuronal proliferation patterns and the timing of developmental progressions. The authors present solid support for the presence of type-II NB lineages in the beetle Tribolium with the same molecular characteristics as the counterparts in the fly Drosophila, but differences in lineage size and number. While presenting a number of interesting observations, further evidence will be required to show that the observed differences are indeed responsible for the differences in developmental timing of the central complex in the two insect species.

This important manuscript describes a creative approach using dual-component gRNAs to create a new class of molecular proximity sensors for genome editing. The authors demonstrate that this tool can be coupled with several different gene editing effectors, showing convincingly that the tool functions as intended. This study not only introduces a first-of-its kind approach, but through careful measurements also enables future further development of the technology.

eLife assessment

This is a valuable study providing solid evidence that the Mediator kinase module mediates an elevated inflammatory response, manifested by heightened cytokine levels, associated with Downs syndrome (DS) via transcriptional changes impacting cell signaling and metabolism, which has significance for the treatment of DS and other chronic inflammatory conditions. Particular strengths of the study include the combined experimental approaches of transcriptomics, untargeted metabolomics, cytokine screens, and the use of sibling-matched cell lines (trisomy 21 vs disomy 21) from various donors. Less certain is that the Mediator kinase plays a meaningful role in regulating mRNA splicing. Further evidence that nuclear receptors are activated by changes in lipid levels and that mitochondrial function is substantially reduced on Mediator kinase inhibition would strengthen the work.

eLife assessment

This is a valuable study that provides CCR7-APEX2 proximity labelling mass spectrometry data that is expected to provide new insights into CCR7 signalling partners and pathways. The study is technically solid and easy to follow, however, there are some concerns that many of the highlighted findings are repetitive of prior work and that this is not clearly acknowledged. It would increase the impact of the study if the confirmatory nature of some findings were acknowledged. This is of value to the community, and there are likely multiple opportunities to use the APEX2 data set to extend these findings, strengthen some claims, and even explore a new pathway identified in the APEX2 data set.
