Here, using a yeast model, we reveal that Sod1 is an indispensable guardian of genomic integrity. Its absence unleashes a genomic storm: whole-genome sequencing uncovered a dramatic surge in single nucleotide variations (13-fold), loss of heterozygosity (12-fold), chromosomal rearrangements (4-fold), and a staggering 48-fold increase in aneuploidy. Remarkably, this genomic instability was completely abolished under anaerobic conditions, identifying reactive oxygen species as the sole executioner. We demonstrate that Sod1 deficiency sculpts a unique mutational landscape dominated by C:G to A:T transversions-a molecular fingerprint of 8-oxoguanine overproduction. Mechanistically, these lesions are exacerbated by error-prone DNA polymerase ζ but mitigated by the concerted actions of Ogg1-mediated excision and DNA polymerase η. Critically, we show that Amyotrophic Lateral Sclerosis-associated variants are not created equal: the H48Q mutation shatters genome stability, whereas others (A4V, G36R, and G93A) remain benign in this context. Unlike yeast Sod1, human Sod1 is highly resistant to amino acid substitutions outside copper-binding sites, thus preventing the loss of enzyme function.

Using an unbiased forward genetic screen in Caenorhabditis elegans, we identified a gain-of-function mutation in the EAG-subfamily KCNH channel EGL-2 that suppresses sleep. The mutation (G574E) alters a highly conserved glycine residue at the interface between CNBHDs of adjacent channel subunits. EGL-2 functions cell-autonomously in the central sleep-promoting neuron ALA. In vivo calcium imaging showed that the gain-of-function mutation suppresses sleep by inhibiting ALA neuronal activity, consistent with enhanced potassium channel activity. Genetic analysis demonstrated that the sleep-suppressing phenotype of G574E requires both an intact potassium selectivity filter and the intrinsic ligand-occupied CNBHD. A second substitution at the same glycine (G574R), which introduces a positively charged side chain in contrast to the negatively charged side chain in G574E, similarly suppresses sleep, indicating that perturbation of the CNBHD-CNBHD interface, rather than the specific amino acid change, underlies the phenotype. Moreover, mutations at the corresponding residue in the ERG-subfamily KCNH channels C. elegans UNC-103 and human hERG also produce gain-of-function effects, and electrophysiological analysis showed that hERG(G749R) shifts voltage-dependent channel activation to more negative potentials and accelerates activation kinetics.

The Deafness Variation Database (DVD) is a public resource of deafness variants, containing 381,924 missense variants across 224 genes, with 303,577 classified as a variant of uncertain significance (VUS). To address the challenge of evaluating each deafness associated VUS, we evaluate a family of probabilistic frameworks to quantify the strength of computational evidence based on ACMG/AMP recommendations. First, CADD and REVEL are compared using Bayesian models parameterized using either a ClinVar 2019 dataset or labeled DVD variants. The REVEL model built using the DVD dataset demonstrates the best accuracy, sensitivity, and specificity. Incorporation of (in)tolerance to missense variation based on sorting each gene into three bins (tolerant, average, intolerant) shows that intolerant DVD genes are consistent with a higher prior probability of being pathogenic (25.7%) than average (10.7%) or tolerant (8.7%) genes. Finally, the impact of protein folding stability was incorporated into the Bayesian model and surpassed the simpler versions while also offering a biophysical rationale for the disease mechanism. The 28,866 VUSs that reach a posterior probability of pathogenicity above 98% based on the protein-folding informed Bayesian model were prioritized as likely to be pathogenic. Overall, 54,752 missense variants (14.3% of 381,924) are predicted to cause modest protein folding destabilization of greater than 1.0 kcal/mol, while 18,706 of these are prioritized VUSs (34% of 54,752). 22,237 missense variants (6.2% of 381,924) are predicted to cause more severe protein folding destabilization of at least 2 kcal/mol with 12,424 being prioritized VUSs (55.8% of 22,237).

Activation of FtsWI is thought to occur through an allosteric cascade initiated by the late-arriving divisome protein FtsN and transmitted via the FtsQ-FtsL-FtsB (FtsQLB) complex, but the molecular details of this process remain incompletely defined and differ across species. Here, using the conditional essentiality of ftsN in Pseudomonas aeruginosa, we identify substitutions in the non-enzymatic pedestal domain of FtsI that bypass the requirement for FtsN. These mutations restore cell division in ΔftsN cells, suppress dominant-negative phenotypes of activation-defective ftsL alleles, and reduce cell length in an otherwise wild-type background, demonstrating that they alter FtsWI regulation to overcome the requirement for stimulation by both FtsN and FtsQLB. Mapping these mutations onto the P. aeruginosa FtsQLBWI structure reveals that they cluster on distinct surfaces of the pedestal domain. Because some of these substitutions have been identified in clinical P. aeruginosa isolates with increased aztreonam resistance, we next asked whether these regulatory substitutions alter β-lactam susceptibility. Variants at the FtsI-FtsL interface modestly reduce susceptibility to multiple β-lactam antibiotics, whereas a variant on the opposite face of the pedestal domain produces striking FtsN-dependent hypersusceptibility to the same molecules. These findings show that the FtsI pedestal domain plays a central role in the regulation of FtsWI and reveal a previously unrecognized relationship between divisome regulation and β-lactam susceptibility. More broadly, our work identifies the pedestal domain as a regulatory hub that integrates multiple inputs controlling septal PG synthesis and highlights its potential relevance to β-lactam resistance in clinical P. aeruginosa isolates.</p>","PeriodicalId":49007,"journal":{"name":"PLoS Genetics","volume":"22 9","pages":"e1012319"},"PeriodicalIF":3.9,"publicationDate":"2026-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13641693/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149075904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Loss of LRE function causes inhibited growth and poor survival due to protein malnutrition. Previously, we reported that in zebrafish loss of Plasmolipin (pllp), an endosomal membrane protein highly expressed in LREs, impairs LRE differentiation and dietary protein absorption, resulting in marked reduction in survival rates. Raising pllp homozygous mutants surviving to adulthood and in-crossing them for multiple generations resulted in a recovery of survival and growth, even when fed a low protein diet. To uncover mechanisms underlying this phenomenon, we compared the older adapted pllp allele with genetically related wild type (WT) fish and a newly generated pllp mutant allele. Using transcriptome profiling and quantitative protein absorption assays, we found that the adapted pllp mutants exhibit upregulation of LRE endocytic components associated with a capacity for protein absorption that exceeds that of WT. This hyperactivation of LRE endocytic and absorptive activity is accompanied by transcriptional regulation of immune genes that may contribute to the enhanced survival of pllp mutants in the face of increased exposure to environmental antigens. Genetic analyses indicate that these divergent phenotypes emerge gradually over generations and can recur in an independently generated pllp allele upon inbreeding and natural selection.
