Identification of regenerating island-derived protein 3E in dogs

ABSTRACT: Our aim was to identify Regenerating islet-derived (REG proteins in dogs. We annotated REG-family members in the canine genome and proteome, and identified one member of the REG3 subfamily, consequently termed REG3E by the Vertebrate Gene Nomenclature Committee. We verified REG3E gene expression using publicly available RNA-seq data (www.barkbase.org). We investigated the presence of REG3E protein in canine pancreatic tissue and plasma with Western blot and immunohistochemistry, using anti-human REG3A antibodies. Protein identity was subsequently confirmed with mass spectrometry on canine pancreas homogenates and plasma.

Characterisation of the Semliki Forest Virus-host cell interactome reveals the viral capsid protein as an inhibitor of nonsense-mediated mRNA decay

Project description:Understanding the complex interactions between the viral and the host cell proteins is crucial for elucidating the mechanisms underlying successful virus replication strategies and for developing specific antiviral interventions. This project presents the first comprehensive protein-protein interaction map between the proteins of Semliki Forest Virus (SFV), a mosquito-borne member of the alphaviruses, and host cell proteins. We additionally overlay an SFV siRNA screen to assign pro- or antiviral functions to the interactors. Among the many identified cellular interactors of SFV proteins, there was an enrichment of factors involved in translation and nonsense-mediated mRNA decay (NMD). Validating these findings, we observed a general inhibition of NMD during SFV infection and demonstrated that transient expression of the SFV capsid protein was sufficient to inhibit NMD in cells.

Developmental mRNA clearance by PIWI-bound endo-siRNAs in Paramecium

Project description:The clearance of untranslated mRNAs by Argonaute proteins is essential for embryonic development in metazoans. However, it is currently unknown whether a similar process exists in unicellular eukaryotes. The ciliate Paramecium tetraurelia harbors a vast array of Argonaute proteins of the Piwi-clade involved in various small RNA pathways, many of which have not yet been investigated. In this work, we investigated the function of a Piwi protein, Ptiwi08, whose expression is limited to a narrow time window during development, concomitant with the start of zygotic transcription. We show that Ptiwi08 acts in an endo-siRNA pathway involved in the clearance of a set of mRNAs at the post-transcriptional level. Based on their features, we hypothesized that these mRNAs may be untranslated. In this dataset, we used mass spectrometry to determine whether any protein products of these mRNAs can be found.

Metaproteome plasticity sheds light on the ecology of the rumen microbiome and its connection to host traits

Project description:The arsenal of genes that microbes express reflect the way in which they sense their environment. We have previously reported that the rumen microbiome composition and its coding capacity are different in animals having distinct feed efficiency states, even when fed an identical diet. Here, we reveal that many microbial populations show divergent proteome production in function of the feed efficiency state. Thus, proteomic data serve as a strong indicator of host feed efficiency state phenotype, overpowering predictions based on genomic and taxonomic information. We highlight protein production of specific phylogenies associated with each of the feed efficiency states. We also find remarkable plasticity of the proteome both in the individual population and at the community level, driven by niche partitioning and competition. These mechanisms result in protein production patterns which exhibit functional redundancy and checkerboard distribution that are tightly linked to the host feed efficiency phenotype. By linking microbial protein production and the ecological mechanisms that act within the microbiome feed efficiency states, our present work reveals a layer of complexity that bears immense importance to the current global of food security and sustainability.

40S hnRNP particles are a novel class of nuclear biomolecular condensates

Project description:Heterogenous nuclear ribonucleoproteins (hnRNPs) are abundant proteins implicated in various steps of RNA processing that assemble on nuclear RNA into larger complexes termed 40S hnRNP particles. Despite their initial discovery 55 years ago, our understanding of these intriguing macromolecular assemblies remains limited. We biochemically purified native 40S hnRNP particles and determined their complete protein composition by label-free quantitative mass spectrometry, identifying A-group and C-group hnRNPs as the major protein constituents.

Relating the equine « cumulome » to the developmental competence of the corresponding oocyte

Project description:In vitro maturation (IVM) of equine oocytes results in a reduced developmental capacity compared to in vivo matured oocytes. Cumulus cells mirror oocytal well-being through close bidirectional communication. After maturation, the cumulus complex is not required anymore. Therefore, these cells are a unique noninvasive source to investigate metabolism during this crucial developmental phase. This study analyzed the “Cumulome” (metabolome and proteome of cumulus cells) with different developmental potential: Not matured (NM; n=18), Cleaved (CL; n=15) and Blastocyst (BL; n=19).

The bovine cumulus proteome of cumulus oocyte complexes that successfully matured or failed to mature after maturation in-vitro and in-vivo

Project description:The oocyte forms a complex with their somatic cumulus cells within the follicle throughout the preovulatory maturation steps. Cumulus cells support their oocyte not only through mechanical protection but also with a close bidirectional exchange of metabolites. Analysis of the oocytes cumulus gives the opportunity to explore non-invasively oocytal well-being and quality. In vitro maturation (IVM) is the first rate-limiting step in in vitro embryo production. Analysis of protein expression in cumulus cells around this critical step helps to explore the impact of maturation conditions and to examine an influence on maturational competence of the oocyte. The goal of this study was the comparison of the cumulus proteome of oocytes with and without maturational competence matured under in vivo and in vitro conditions. Therefore twenty cumulus samples corresponding to single oocytes were analysed. Half of the samples were matured in vivo and the other half in vitro. For each maturation group, cumulus from oocytes matured successfully (SM; n=5) and failed to mature (FM; n=5) were analysed.

Obatoclax rescues FUS-ALS phenotypes in iPSC-derived neurons by inducing autophagy

Project description:Disruption of protein homeostasis plays an essential role in neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS). One strategy for restoring protein homeostasis and protecting neurons is to de-repress autophagy by disrupting the inhibitory BECN1/BCL2 complex, which has been shown to improve healthspan and lifespan in mice. We screened small molecule BH3 mimetics using an induced pluripotent stem cell (iPSC)-based model of ALS with a FUS mutation and identified obatoclax rescued neurons at by reducing cytoplasmic FUS levels, restoring protein homeostasis, and reducing degeneration.
