  This study interrogates cell non-autonomous signaling between GABAergic neurons and somatic tissues in the nematode C. elegans. The authors report that mitochondrial stress in only GABAergic neurons extends lifespan and improves healthspan, phenotypes that are dependent on the transcription factor daf-16/FOXO3a. However, while the findings may be valuable to furthering our understanding of neuronal control of aging and health, the current evidence is incomplete and additional experiments are needed to support their claims.

  This study presents valuable insight into a nuclear-encoded transcription factor network and the role of one transcription factor Clifford in mitochondrial biogenesis. The experimental design, data collection, and analyses are solid. Addressing a few points related to mitochondrial and ETC biogenesis will further strengthen the study.

  This useful study identifies amino acid residues in the C. elegans RNA-binding protein NHL-2 that are required for RNA binding in vitro and NHL-2 function in vivo. The evidence in support of the authors' mechanistic model is currently incomplete, as data implicating specific NHL-2 amino acids in RNA binding per se in vivo are not presented. This manuscript will be of interest to scientists working in the area of gene regulation.

  In the last 15 years, large-scale association studies (GWAS) have served to estimate the association between genome-wide common variants and a large number of disparate traits and diseases in humans. This valuable method provides a new way to find correlations between the genetic component of a phenotype of interest, and all this wealth of genetic information. This software adds as a new tool to investigate genetic correlation between traits, and to generate new mechanistic hypotheses and dissect the role of the observed associations in disease heterogeneity. The results of the application of their method are solid and generally agree with what others have seen using similar AD and UKB data.

  This potentially important paper reports on interactions between L1TD1, an RNA binding protein (RBP), and the ancestral LINE-1 retrotransposon from which it originates. Overall, the results support a model in which L1TD1 and LINE-1 ORF1p have synergistic effects on LINE-1 retrotransposition, but the evidence for whether this is through direct protein-protein interaction or through simultaneous interaction with LINE-1 RNA is currently incomplete.

  This important mouse study shows that wild-type female progeny of Khdc3 mutants have abnormal gene expression relating to hepatic metabolism, which persists over multiple generations and passes through both female and male lineages. Information about litter size and a full phenotypic description of the phenotype of each progeny should be included to evaluate the impact of KHDC3 mutation on the progeny; in its current state, the evidence for the authors' claims is incomplete. A role for small RNAs on this phenomenon is proposed but has not been functionally validated. The work will be of interest to researchers in the field of DNA-independent mechanism of inheritance. Mentioning the experimental organism in title and abstract would ensure that it targets the appropriate audience.
