Project description:Single-cell RNA-sequencing was performed on the tumor microenvironment of the glioblastomas isolated from PDOX models (Golebiewska et al., Acta Neuropathologica, 2020; Oudin et al., STAR Protocols 2021). Sample names correspond to PDOX models. Normal mouse brain was used as a contol. One PDOX model was treated with temolozomide (P3TMZ).

Project description:To allow estimation of the complexity of the antennal transcriptome between sexes as well as in comparison with a non-antennal tissue, microarrays were designed based on an assembly of new 454 sequence data from the antenna and publicly available data including 454 data from the larval midgut. The microarrays were hybridized with samples generated from the repsecitve tissues from 3 (antenna) and 5 (midgut) animals per sample, with four independent samples per sex (antenna) and tissue (midgut).

Project description:<p>Genome-wide association studies (GWAS) identified thousands of genetic loci associated with complex plant traits, including many traits of agronomical importance. However, functional interpretation of GWAS results remains challenging because of large candidate regions due to linkage disequilibrium. High-throughput omics technologies, such as genomics, transcriptomics, proteomics, and metabolomics open new avenues for integrative systems biological analyses and help to nominate systems information supported (prime) candidate genes. In the present study, we capitalize on a diverse canola population with spring-type 477 lines which was previously analysed by high-throughput phenotyping (Knoch et al., 2020), and by RNA sequencing and metabolite profiling for multi-omics-based hybrid performance prediction (Knoch et al., 2021). We deepened the phenotypic data analysis, now providing 123 time-resolved image-based traits, to gain insight into the complex relations during early vegetative growth and re-analysed the transcriptome data based on the latest Darmor-bzh v10 genome assembly (Rousseau-Gueutin et al., 2020). Genome-wide association testing revealed 61,298 robust quantitative trait loci (QTL) including 187 metabolite-QTL, 56,814 expression-QTL, and 4,297 phenotypic QTL, many clustered in pronounced hotspots. Combining information about QTL colocalisation across omics layers and correlations between omics features allowed us to discover prime candidate genes for metabolic and vegetative growth variation. Prioritized candidate genes for early biomass accumulation include A06p05760.1_BnaDAR (PIAL1), A10p16280.1_BnaDAR, C07p48260.1_BnaDAR (PRL1), and C07p48510.1_BnaDAR (CLPR4). Moreover, we observed unequal effects of the Brassica A and C subgenomes on early biomass production.</p><p><br></p>

Project description:Toal 13 patient samples (Iliac or pyramidal cancellous) were collected with lung cancer who were pathologically diagnosed in Dazhou Central Hospital from June 2020 to January 2021. Patients were monitored by a professional orthopaedic surgeon in the interventional room prior to collecting the samples. This study was approved by the ethics committee and informed consent of patients (IRB2020023). The obtained samples are quickly placed into an Eppendorf tube with PBS buffer for flushing the blood. Then, the samples were cleaned in a cell preservation solution. Finally, the cleaned samples were placed into a sterile EP tube with 2 mL cell preservation solution before being stored in a refrigerator at 4 ° C. Further, the samples with two replicates were sequenced in a 10x genomic chromium platform with a chemistry library (Single Cell 3; v3). The samples were sequenced at BGI (https://www.bgi.com).

Project description:Anti-tick vaccines have proved to be an effective and sustainable method for the control of tick infestations and tick-borne diseases with clear advantages over the application of chemical acaricides (Šmit and Postma, 2016; de la Fuente, 2018; Ndawula and Tabor, 2020). Moreover, the efficacy of acaricide application against Ornithodoros ticks is seriously limited owing to their endophilic/nidicolous life style, which make these ticks less accessible to the chemical acaricides (Astigaraga et al., 1995). Success in tick vaccine development is largely dependent on identification of new and highly protective tick antigens. Searching of new candidate protective antigens is currently being approached among tick molecules that play important biological functions at the tick-host interface, and more precisely among the salivary and intestinal proteins involved in biological processes specifically evolved by ticks to adapt to haematophagy (de la Fuente et al., 2016; Oleaga et al., 2021; Pérez-Sánchez et al., 2021). Accordingly, next-generation sequencing (NGS) and high-throughput proteomics technologies are been used to explore the transcriptome and proteome of the salivary glands/saliva and midguts of an increasing number of tick species and obtain the corresponding sialomes and mialomes (Chmelař et al., 2016; Almeida-Martins et al., 2020; Mans et al., 2020; Oleaga et al., 2021). These studies have identified a wealth of tick molecules related to tick haematophagy, tick-host interplay and pathogen transmission, which can then be scrutinized and filtered in vaccinomics pipelines for selecting candidate protective antigens (Chmelař et al., 2016; Maruyama et al., 2017; Antunes et al., 2018; de la Fuente et al., 2018; Ren et al., 2019; Couto et al., 2021). Similarly, we were also interested in characterizing the O. erraticus sialome. As far as O. erraticus saliva must contain all the bioactive molecules that the tick need to successfully feed, decoding its composition will lead to the discovery of new antigen targets for developing vaccines for the control and prevention of O. erraticus infestations and the diseases it transmits. Accordingly, the objective of the present work was to obtain the proteome of the saliva of O. erraticus adult ticks. For this, we have used a proteomics informed by transcriptomics approach to analyse female and male saliva separately using two different mass spectrometry approaches: liquid chromatography-tandem mass spectrometry (LC-MS/MS) in data-dependent acquisition (DDA) mode, and Sequential Window Acquisition of all Theoretical fragment ion spectra Mass Spectrometry (SWATH MS). SWATH MS is a specific variant of data-independent acquisition (DIA) methods that combines deep proteome coverage capabilities with quantitative consistency and accuracy (Ludwig et al., 2018). Here we reported the identification of 387 non-redundant proteins in the saliva of O. erraticus adult ticks as well as a qualitative and quantitative comparison of the saliva protein composition between both sexes. The integration of O. erraticus sialoproteomic and sialotranscriptomic datasets facilitate a better understanding of the physiology of feeding in O. erraticus and will drive the discovery of new and more effective antigen targets for development of anti-tick vaccines.

Project description:While DNA methylation is an important gene regulatory mechanism in mammals (Razin and Riggs 1980; Moore, Le, and Fan 2013), its function in arthropods remains poorly understood. Studies in eusocial insects have argued for its role in caste development by regulating gene expression and splicing (Elango et al. 2009; Lyko et al. 2010; Bonasio et al. 2012; Flores et al. 2012; Foret et al. 2012; Li-Byarlay et al. 2013; Marshall, Lonsdale, and Mallon 2019; Shi et al. 2013)(Alvarado et al. 2015; Kucharski et al. 2008). However, such findings are not always consistent across studies, and have therefore remained controversial (Arsenault, Hunt, and Rehan 2018; Cardoso-Junior et al. 2021; Harris et al. 2019; Herb et al. 2012; Libbrecht et al. 2016; Oldroyd and Yagound 2021b; Patalano et al. 2015). Here we use CRISPR/Cas9 to mutate the maintenance DNA methyltransferase DNMT1 in the clonal raider ant, Ooceraea biroi. Mutants have greatly reduced DNA methylation but no obvious developmental phenotypes, demonstrating that, unlike mammals (Brown and Robertson 2007; En Li, Bestor, and Jaenisch 1992; Jackson-Grusby et al. 2001; Panning and Jaenisch 1996), ants can undergo normal development without DNMT1 or DNA methylation. Additionally, we find no evidence of DNA methylation regulating caste development. However, mutants are sterile, while in wildtypes, DNMT1 is localized to the ovaries and maternally provisioned into nascent oocytes. This supports the idea that DNMT1 plays a crucial but unknown role in the insect germline (Amukamara et al. 2020; Arsala et al. 2021; Bewick et al. 2019; Schulz et al. 2018; Ventós-Alfonso et al. 2020; Washington et al. 2020).
