DNA Double-Strand Break Movement in Heterochromatin Depends on the Histone Acetyltransferase dGcn5.

(Submitter supplied) Cells employ diverse strategies to repair double-strand breaks (DSBs), a dangerous form of DNA damage that threatens genome integrity. Eukaryotic nuclei consist of different chromatin environments, each displaying distinct molecular and biophysical properties that can significantly influence the DSB repair process. Specifically, DSBs arising in the compact and silenced heterochromatin domains have been found to move to the heterochromatin periphery in mouse and Drosophila to prevent aberrant recombination events. more...

Manipulating mitochondrial reactive oxygen species alters survival in unexpected ways in a Drosophila Cdk5 model of neurodegeneration

(Submitter supplied) Reactive oxygen species (ROS) are associated with aging and neurodegeneration, but the significance of this association remains obscure. Here, using a Drosophila Cdk5 model of age-related neurodegeneration, we probe this relationship in the pathologically relevant tissue, the brain, by quantifying three specific mitochondrial ROS and manipulating these redox species pharmacologically. Our goal is to ask whether pathology-associated changes in redox state are detrimental for survival, whether they may be beneficial responses to pathology, or whether they are simply covariates of pathology that do not alter viability. more...

HLH-30/TFEB-regulated autophagy mediates sexual dimorphism in immunity in Caenorhabditis elegans

(Submitter supplied) Sexual dimorphism affects diverse biological functions such as immune responses. However, mechanisms by which different sexes alter immunity remained largely unknown. By using Caenorhabditis elegans as a model, here we show that male animals exhibit enhanced immunity against various pathogenic bacteria via upregulating autophagy. We found that male C. elegans displayed upregulation of helix loop helix 30 (HLH-30)/transcription factor EB (TFEB), a transcription factor crucial for autophagy, which contributed to the enhanced anti-bacterial immunity. more...

A Transcription Factor Functional Atlas of Germline Development in Caenorhabditis elegans

(Submitter supplied) Fertility requires the faithful proliferation of germ cells and their differentiation into gametes. Controlling these cellular states demands precise timing and expression of gene networks. Transcription factors (TFs) play critical roles in gene expression networks that influence germ cell development. There has, however, been no functional analysis of the entire TF repertoire in controlling in vivo germ cell development. more...

Regeneration-specific lncRNA CR40469 is essential for Drosophila regeneration

(Submitter supplied) The discovery of functional long non-coding RNAs (lncRNAs) changed the initial concept of lncRNAs as transcriptional noise. Since then, a wide array of functions have been associated with lncRNAs, including changes in the chromatin state and gene expression, modulation of splicing, translation or degradation of mRNAs. Also, many lncRNAs are known to be deregulated in multiple diseases, including cancer and neurological disorders. more...

Mettl1-dependent m7G tRNA modification is essential for maintaining fertility and proper spermatogenesis in Drosophila melanogaster

(Submitter supplied) N7-methylguanosine (m7G) in variable loop region of tRNA stabilizes target tRNA expression, which is catalyzed by METTL1/WDR4 heterodimer. Here, we unveil essential functions of Mettl1 in Drosophila fertility. Mettl1-knockout (Mettl1-KO) decreases elongated spermatid and mature sperm, which is fully rescued by Mettl1-transgene expression, but not catalytic dead Mettl1-transgene, demonstrating that Mettl1-dependent m7G is required for spermatogenesis. more...

The transcriptional signatures of Caenorhabditis elegans dauer larvae

(Submitter supplied) Both plasticity and robustness are pervasive features of developmental programs. The dauer in Caenorhabditis elegans is an alternative to the third larval stage of the nematode and is an example of phenotypic plasticity. The dauer is an arrested, hypometabolic state that undergoes dramatic changes in gene expression compared to conspecifics that continue development, and can be induced by several adverse environments or genetic mutations that act as independent and parallel inputs into the larval developmental program. more...

Serotonin deficiency from constitutive SKN-1 activation drives pathogen apathy

(Submitter supplied) When an organism encounters a pathogen, the host innate immune system is activated to defend against pathogen colonization and the toxic xenobiotics produced. C. elegans employ multiple defense systems to ensure survival when exposed to Pseudomonas aeruginosa (PA14) including activation of the cytoprotective transcription factor SKN-1/NRF2. Although wildtype C. elegans quickly learn to avoid pathogens, here we describe a peculiar apathy to PA14 in animals with constitutive activation of SKN-1, whereby animals choose not to leave while continuing to feed on the pathogen even when a non-pathogenic food option is available. more...

MBL-1/Muscleblind regulates neuronal differentiation and controls the splicing of a terminal selector in Caenorhabditis elegans

(Submitter supplied) The muscleblind family of mRNA splicing regulators is conserved across species and regulate the development of muscles and the nervous system. However, how Muscleblind proteins regulate neuronal fate specification and neurite morphogenesis at the single-neuron level is not well understood. In this study, we found that the C. elegans Muscleblind/MBL-1 promotes axonal growth in the touch receptor neurons (TRNs) by regulating microtubule stability and polarity. more...

Widespread regulation of the maternal transcriptome by Nanos in Drosophila

(Submitter supplied) The translational repressor Nanos (Nos) regulates a single target, maternal hunchback (hb) mRNA, to govern abdominal segmentation in the early Drosophila embryo. Nos is recruited specifically to sites in the 3'-UTR of hb mRNA in collaboration with the sequence-specific RNA-binding protein Pumilio (Pum); on its own, Nos has no binding specificity. Nos is expressed at other stages of development, but very few mRNA targets that might mediate its action at these stages have been described. more...

Effect of misregulation of mitochondrial 6mA on gene expression in C. elegans

(Submitter supplied) In virtually all eukaryotes, the mitochondrial genome (mitochondrial DNA, mtDNA) encodes proteins necessary for oxidative phosphorylation (OXPHOS) and the RNA machinery required for their synthesis inside the mitochondria. Appropriate regulation of mtDNA copy number and expression is essential for ensuring the correct stoichiometric formation of OXPHOS complexes assembled from both nuclear- and mtDNA-encoded subunits. more...

Alternative Splicing of bunched Confers a Dual Role in Hippo Pathway-dependent Growth and Tumorigenesis

(Submitter supplied) Alternative splicing is a fundamental mechanism that generates functionally distinct proteins from individual genes, contributing to gene regulation and proteomic diversity. In Drosophila, the bunched (bun) gene, a member of the TSC-22 domain gene family, undergoes alternative splicing, yielding diverse protein isoforms involved in crucial biological processes. Nevertheless, the specific roles and regulatory mechanisms of each isoform remain elusive. more...

XOL-1 regulates developmental timing by modulating the H3K9 landscape in C. elegans early embryos

(Submitter supplied) Sex determination in the nematode C. elegans is controlled by the master regulator XOL-1 during embryogenesis. Expression of xol-1 is dependent on the ratio of X chromosomes and autosomes, which differs between XX hermaphrodites and XO males. In males, xol-1 is highly expressed and in hermaphrodites, xol-1 is expressed at very low levels. XOL-1 activity is known to be critical for the proper development of C. more...

The Drosophila Estrogen-Related Receptor acts within the larval fat body to promote triglyceride storage

(Submitter supplied) Members of the Estrogen-Related Receptor (ERR) family of nuclear receptors (NR) serve a key role in coordinating triglyceride (TAG) accumulation with juvenile growth and development. In both insects and mammals, loss of ERR activity disrupts (TAG) storage during the post-embryonic growth phase, with loss-of-function mutations in mouseErraandDrosophila melanogaster dERRinducing a lean phenotype. However, the role of insect ERRs in controlling TAG accumulation remains poorly understood, as previous multiomic studies largely relied on whole animal analyses. more...
