WAGO-4 Localization to Germ Granules Is Important for Its Accurate Small RNA Loading

Project description:There were several MS experiments used in this study: 1) Proximity labeling of the P granules 2) Protein levels estimation from whole worm lysates and 3) wago-4 KO expression check (PRM analysis). 1) Proximity labeling strategy was used to estimate P granule composition in 3xFG mutant (FG domains of GLH-1, GLH-2, and GLH-4 mutated) and compare it to the WT. PGL-3 was tagged with TurboID at its native locus using CRISPR-Cas9. Biotinylation level was determined after streptavidin pull-down followed by MS analysis, serving as a proxy for protein enrichment in P granules. 2) Whole-worm lysate MS analysis was performed on 3xFG mutant worms to assess the worm proteome at an elevated temperature (26 °C), where these mutants exhibit a fecundity phenotype. 3) A STOP codon was introduced in the second exon of the WAGO-4 gene at its native locus in C. elegans (WAGO-4 KO). To assess whether the WAGO-4 protein is expressed in this strain, lysates from WAGO-4 KO (in triplicate) and N2 (WT control) were analyzed using PRM-MS.

Shuffled ATG8 interacting motifs form an ancestral bridge between UFMylation and C53-mediated autophagy

Project description:UFMylation mediates the covalent modification of substrate proteins with UFM1 (Ubiquitin- fold modifier 1) and regulates the selective degradation of endoplasmic reticulum (ER) via autophagy (ER-phagy) to maintain ER homeostasis. Specifically, collisions of the ER-bound ribosomes trigger ribosome UFMylation, which in turn activates C53-mediated autophagy that clears the toxic incomplete polypeptides. C53 has evolved non-canonical shuffled ATG8 interacting motifs (sAIMs) that are essential for ATG8 interaction and autophagy initiation. Why these non-canonical motifs were selected during evolution, instead of canonical ATG8 interacting motifs remains unknown. Here, using a phylogenomics approach, we show that UFMylation is conserved across the eukaryotes and secondarily lost in fungi and some other species. Further biochemical assays have confirmed those results and showed that the unicellular algae, Chlamydomonas reinhardtii has a functional UFMylation machinery, overturning the assumption that this process is linked to multicellularity. Our conservation analysis also revealed that UFM1 co-evolves with the sAIMs in C53, reflecting a functional link between UFM1 and the sAIMs. Using biochemical and structural approaches, we confirmed the interaction of UFM1 with the C53 sAIMs and found that UFM1 and ATG8 bound to the sAIMs in a different mode. Conversion of sAIMs into canonical AIMs prevented binding of UFM1 to C53, while strengthening ATG8 interaction. This led to the autoactivation of the C53 pathway and sensitized Arabidopsis thaliana to ER stress. Altogether, our findings reveal an ancestral toggle switch embodied in the sAIMs that regulates C53- mediated autophagy to maintain ER homeostasis.

Arabidopsis and Spirodela Histone PTMs (In case it fits better, the title of the paper will be: “Investigating the transposon silencing landscape of the aquatic monocot Spirodela polyrhiza during clonal growth unveils atypical epigenetic and small RNA patterns”)

Project description:In flowering plants, silencing of transposable elements (TEs) is achieved by the installation of DNA methylation and histone modifications. 24-nt long small-interfering RNAs (siRNAs) guide the deposition of DNA methylation through RNA-directed DNA methylation (RdDM), which can be maintained independently of siRNAs in coordination with H3K9me2. In most angiosperms, RdDM is ubiquitously expressed in vegetative and sexual reproductive tissues. Spirodela polyrhiza (Lemnaceae), represents an exception with low levels of DNA methylation, very low expression of RdDM and near absence of 24-nt siRNAs during its clonal vegetative propagation. Moreover, some components of RdDM, DNA methylation maintenance and RNA silencing are absent from the genome. By investigating the distribution of epigenetic marks on TEs, we show that Spirodela epigenome is shaped by the loss of DNA methylation and H3K9me2 as TEs decay. Nonetheless, such abundant TE remnants remain silenced and marked by H3K9me1. In contrast, scarce, relatively intact TEs display high levels of DNA methylation, H3K9me2 and siRNAs whose patterns resemble those of TEs subjected to RdDM in other angiosperms. Furthermore, despite the absence of DCL2 in duckweeds, Spirodela can produce 22-nt siRNAs, not only from TEs, but from diverse sources of double-stranded (ds)RNA. Our data suggests that RdDM might still be functional during vegetative clonal growth, albeit tissue or developmentally regulated, and highlights the use of alternative models to further understand and explore the diversity of silencing pathways in plants.

Discovery of the targets of the immune response to chronic lymphocytic leukemia in 2 patients using protein microarrays

Project description:The binding of serum immunoglobulins to proteins was compared using serum from after and before an immunotherapeutic intervention (donor lymphocyte infusion) in two patients who had relapsed chronic lymphocytic leukemia (CLL) after bone marrow transplant. One Invitrogen ProtoArray was used for each sample. Significant interactions were determined by comparing the before and after samples for each patient separately, using the Concentration-Dependent Analysis described in Marina et al., J Proteome Res, 2008. One sample from before and one sample from after immunotherapy were tested for each patient. Keywords: Immune response discovery One sample from before and one sample from after immunotherapy were tested for each patient.

Discovery of the targets of the immune response to chronic myeloid leukemia in 3 patients using protein microarrays

Project description:Three patients who had relapsed chronic myeloid leukemia after allogeneic bone marrow transplant and received an immunotherapeutic intervention (donor lymphocyte infusion, or DLI) without further treatment were studied. The binding of serum immunoglobulins to proteins after immunotherapy was compared to before in two patients using Invitrogen ProtoArrays from a single lot. For a third patient, comparison was made between two timepoints after immunotherapy against one timepoint before using Invitrogen ProtoArrays from a separate lot. Significant interactions were determined by comparing each after sample separately against the before sample from that patient, using the Concentration-Dependent Analysis described in Marina et al., J Proteome Res, 2008. The goal was to identify proteins with significantly-increased reactivity after donor lymphocyte infusion. Keywords: Immune response discovery One sample from before and one sample from after immunotherapy were tested for 2 patients, and one sample from before and two samples from after immunotherapy were tested for a third patient.

Analysis of transcript abundances in Ectocarpus life cycle mutants

Project description:The aim of this experiment was to compare transcript abundances in parthenotes (i.e. organisms derived by parthenogenetic development of gametes) of two life cycle mutants of the brown alga Ectocarpus siliculosus with transcript abundances in the wild type sporophyte and gametophyte generations. This is of interest because the two mutations, immediate upright (imm) and ouroboros (oro), cause partial and almost complete hometic conversion, respectively, of the sporophyte into the gametophyte. imm parthenotes exhibit gametophyte-like morphology during early development but remain sporophytes in functional terms (they do not produce gametes) whereas oro parthenotes behave as functional gametophytes and are morphologically indistinguishable from gametophytes apart from the appearance some minor sporophyte-like features very early in development in some individuals. To minimise genetic background effects the samples for this experiment were derived from a segregating population derived from an imm/IMM oro/ORO sporophyte. Four classes of gametophyte were derived from this sporophyte were IMM/ORO (wild type), imm/ORO, IMM/oro and imm/oro. Parthenomes were bulked to provide a wild type sporophyte sample, samples corresponding to the two individual mutants, plus the double mutant. A wild type gametophyte sample was also compared for comparison. Hybridisations with cDNA derived from these five samples were carried out using a NimbleGen expressed-sequence-tag-(EST-)based microarray carrying probes corresponding to 10,600 of the 16,256 genes identified in the Ectocarpus genome.
