  This important study demonstrates that in Drosophila melanogaster, tachykinin (Tk) expression is regulated by the microbiota. The authors present convincing evidence that axenic flies raised with no microbiota are longer-lived than conventionally reared animals, and that Tk expression and Tk receptors in the nervous system are required for this effect. They further test individual bacterial strains for their role in these effects and connect the effect to loss of lipid stores and suggest that FOXO may be involved in the phenotype, results that are of interest to the fields of environmental perception, host microbiome interactions, and geroscience.

  This important study presents convincing evidence that uncovers a novel signaling axis impacting the post-mating response in females of the brown planthopper. The findings open several avenues for testing the molecular and neurobiological mechanisms of mating behavior in insects, although broad concerns remain about the relevance of some claims.

  This study integrates large-scale behavioral, genetic, and molecular analyses in animal models to investigate morphine response. Utilizing high-quality, time-series Quantitative Trait Loci (QTL) mapping, the work provides compelling evidential support for novel, time-dependent genetic interactions (epistasis). A fundamental result of this rigorous analysis is the discovery of a novel Oprm1-Fgf12-MAPK signaling pathway, which offers new insights into the mechanisms of opioid sensitivity.

Redox Dyshomeostasis Links Renal and Neuronal Dysfunction in Drosophila Models of Gaucher and Parkinson’s Disease

• Curated by eLife

  eLife Assessment

  This is a valuable manuscript that reframes Gaucher's disease pathology through the analysis of renal health, using a Drosophila model mutant for glucocerebrosidase (GBA1). The authors provide physiological and cellular data showing that renal dysfunction may be a critical disease-modifying feature. This work broadens the field's focus beyond the nervous system to include systemic ionic regulation as a potential contributor to disease initiation and progression. The genetic and experimental approaches are solid and offer a rationale for investigating analogous dysfunction in human tissues; however, several claims extend beyond the presented evidence and would benefit from additional experimental support to fully support the conclusions.

Abundant Parent-of-origin Effect eQTL: The Framingham Heart Study

  eLife Assessment

  This important study provides a systematic investigation of parent-of-origin (POE) effects on gene expression using large trio-based data from the Framingham Heart Study, uncovering thousands of potentially novel associations. While the findings are potentially significant, the statistical support for classifying POE eQTLs and some downstream analyses is incomplete, and more stringent re-analysis is needed. With such revisions, the work would serve as a foundation for advancing understanding of POEs and their role in gene regulation.

  This study presents valuable findings regarding the basic molecular pathways leading to the cystogenesis of Autosomal Dominant Polycystic Kidney Disease, suggesting BICC1 functions as both a minor causative gene for PKD and a modifier of PKD severity. Solid data were supplied to show the functional and structural interactions between BICC-1 and PKD2 and their relevance to the pathogenesis of ADPKD, although the characterization of such interactions remains to be developed further and the clinical relevance is currently unclear.

Independent validation of transgenerational inheritance of learned pathogen avoidance in Caenorhabditis elegans

  This valuable study concerns a model for transgenerational epigenetic inheritance, the learned avoidance by C. elegans of the PA14 pathogenic strain of Pseudomonas aeruginosa. A recent study questioned whether transgenerational inheritance in this paradigm lacks robustness. The authors of this study have worked independently of the group that reported the original phenomenon and also independently of the group that challenged the original report. With solid data, this study independently validates findings previously reported by the Murphy group, confirming that the paradigm is reproducible elsewhere. The reviewers also appreciated the information on reagent sources used by different groups. The present study is therefore of broad interest to anyone studying genetics, epigenetics, or learned behavior.

  This important study reports on the redundant roles of the decapping activators Edc3 and Scd6 in orchestrating post-transcriptional programs to modulate metabolic responses to nutrients in yeast. The authors employed mutagenesis studies in conjunction with a battery of transcriptome-wide analyses to provide convincing evidence supporting their conclusions. Considering the broad implications of post-transcriptional regulation of gene expression, this study will be of interest across a variety of biomedical disciplines ranging from biochemistry and molecular and cellular biology to those specializing in studying various pathologies.
