Meiotic crossover landscape within RAC1 disease resistance gene

ABSTRACT: To study recombination at the fine-scale, we used high-throughput sequencing of 300 to 1,000 crossovers within the RAC1 R gene hotspot. This revealed focused intragenic crossovers, overlapping exons encoding the TIR, NBS and LRR domains. To examine the role of recombination pathways, we repeated this experiment in recq4a recq4b, fancm and recq4a recq4b fancm mutants. Finally, in order to investigate how varying patterns of interhomolog divergence influence local patterns of crossover frequency, we repeated RAC1 pollen typing sequencing in different F1 hybrids.

Gene expression in somatotropic pituitary tumors

Project description:Acromegaly is a severe and life-threatening disease caused by persistent excess of growth hormone (GH) which stimulates the synthesis and secretion of insulin-like growth factor-1 (IGF-1). In the majority (95%) of patients acromegaly is caused by sporadic GH-secreting neuroendocrine pituitary tumor (PitNET). Acromegaly-causing tumors are histologically diverse. The aim was to determine transcriptomic profiles in different histological subtypes and evaluate clinical implication of differential gene expression.

EMpire: Deep isoform level integration of the transcriptome, translatome, and proteome

Project description:In this study, we make used of mRNA-seq and its ability to reliably quantify isoforms, integrating this data with ribosome profiling and LC-MS/MS, to assign ribosome footprints and peptides at the isoform level. We leverage the principle that most cell types, and even tissues, predominantly express a single principal isoform to set isoform-level mRNA-seq quantifications as priors to guide and improve allocation of footprints or peptides to isoforms. Through tightly integrated mRNAseq, ribosome footprinting and/or LC-MS/MS proteomics we demonstrate that a principal isoform can be identified in over 80% of gene products in homogenous HEK293 cell culture and over 70% of proteins detected in complex human brain tissue. Defining isoforms in experiments with matched RNA-seq and translatomic/proteomic data increases the functional relevance of such datasets and will further broaden our understanding of multi-level control of gene expression. In this PRIDE submission you will find the raw files for the HEK293 cell proteomics. Files for the human brain proteomics can be found at PXD005445. We have also uploaded a zip file that contains the input files for our HEK293 cell analysis, and the isoform level output files – there is a separate folder within the zip files for these. The data used to create the manuscript figures is in the Rdata file. Code for assigning peptides and footprints to isoforms can be found on Github here: https://github.com/rkitchen/EMpire

Bl6 Ndp-KO systemic gene therapy whole cochlea samples

Project description:We aimed to identify the effect of an AAV-based NDP gene therapy for Norrie disease. This therapy was tested on an Ndp-KO mouse model previously shown to recapitulate Norrie cochlear phenotype (Bryant et al 2022, PMID 35132964). We used transcriptomic analysis of whole cochlea lysates to determine the effect of this therapy on pathology related genes and downstream targets of Norrin signalling. Mice were treated at postnatal day 2 and cochleas collected for analysis at 2 months old.

Proteomic analysis of clear cell renal cell carcinoma tissue versus matched normal kidney tissue

Project description:We analyzed 84 tumor/normal pairs (177 total) using standard shotgun proteomic techniques in order to characterize the molecular landscape of clear cell renal cell carcinoma (ccRCC) and interrogated changes in protein abundance and biological pathways with ccRCC grade. These tissues were distributed across stage 1 (n = 34), 2 (n = 40), 3 (n = 42), and 4 (n = 52), with 9 pairs also including samples from metastasized tumor. These data can be (and were) combined with a previously published transcriptomic data set from the same sample cohort (NCBI GEO: GSE53757).

RNA-seq of murine bone marrow-derived macrophages (mBMDM) of the wild type (WT) group versus the RBP-J conditionally knockout (CKO) group at 36 hours post HTNV (Hantaan orthohantavirus) infection

Project description:Total RNA was extracted from WT and RBP-JCKO mBMDMs at 36 hpi (HTMV, MOI=1), using TRIzol (Invitrogen). Ribosomal RNA was removed using the Ribo-Zero™ kit (Epicentre Biotechnologies). Fragmented RNA (the average length was approximately 200 bp) was subjected to first-strand and second-strand cDNA synthesis followed by adaptor ligation and enrichment with a low cycle according to the instructions of the NEBNext® Ultra™ RNA Library Prep Kit for Illumina (NEB). The purified library products were evaluated using the Agilent 2200 TapeStation and Qubit®2.0 (Life Technologies). The libraries were paired-end sequenced (PE150, sequencing reads were 150 bp) at Guangzhou Ribo Biotechnology (Guangzhou, China) using the Illumina HiSeq 3000 platform. Transgenic mice type: RBP-JCKO (Lyz2-Cre+ RBP-Jfloxed) C57BL/6J Mice.

Microbial life in permafrost: predictions of microbial response to natural thaw using a multi-omics approach

Project description:Over 20% of Earth’s terrestrial surface is underlain by permafrost that represents one of the largest terrestrial carbon pools, with an estimated ~1700 Pg of carbon (C) contained in the upper 3 m of permafrost. Models estimate that C release from thawing permafrost might represent the largest new transfer of C from the biosphere to the atmosphere as the climate warms. Here we investigated microbial community phylogeny, genetic functional potential gene expression, and protein production patterns along a natural thaw gradient, including permafrost, the seasonally thawed active layer and nearby thawed thermokarst bog, using a combination of molecular “omics” approaches: metagenomics (MG), metatranscriptomics (MT) and metaproteomics (MP). Highlights from these analyses reveal energy yielding microbial processes and potential strategies for microbial survival in permafrost soils, and linkages between biogeochemical process rates and –omics measurements. The results provide new knowledge about microbial life and activity potential in permafrost, the potential importance of iron reduction as a survival strategy under frozen conditions in mineral soils, and the importance of methanogenesis following thaw. The multi-omics strategy demonstrated here enables better mechanistic understanding of the ecological strategies utilized by soil microbial communities in response to climate change.

Meiotic cohesin, chromatin and expression profiling of Arabidopsis thaliana floral buds from wild type and non-CG DNA methylation/H3K9me2 pathway mutant plants (RNA-seq)

Project description:To investigate the impact of disruption of the non-CG DNA methylation/H3K9me2 pathway upon transcription in Arabidopsis, we performed RNA-seq using meiotic-stage floral buds from wild type (Col-0) and kyp/suvh4 suvh5 suvh6 mutant plants. This enabled identification of differentially expressed genes and transposable elements (TEs). TEs that were up-regulated in kyp/suvh4 suvh5 suvh6 relative to wild type were evaluated for over-representation of elements within each TE family.
