Project description:Investigation of whole genome gene expression level changes in Pichia stipitis CBS 6054 grown aerobically in xylose, compared to the same strain grown aerobically in glucose. A six array study using total RNA recovered from three separate cultures of Pichia stipitis CBS 6054 grown in glucose and three separate cultures of Pichia stipitis CBS 6054 grown in xylose. Each array measures the expression level of 374,100 probes (average probe length 53.6 +/- 4.1 nt) tiled across the Pichia stipitis CBS 6054 genome with a median spacing distance of 33 nt. During data processing, probes are filtered to include only those probes corresponding to annotated protein-coding genes.

Project description:To reveal the role of sulfur metabolism genes in memory formation processes, transcriptome libraries were obtained from the heads of 5-day-old naive males. The libraries were generated from Drosophila strains created in our laboratory with deleted cbs genes ( CBS-/-(5) and CBS-/-(8), cse (CSE-/-) and strains with double deletion of cbs and cse genes (CBS-/-,CSE-/-(1) and (CBS-/-,CSE-/-(2). Strain 58492, in which deletions were introduced by the CRISP/CAS9 method, was used as a control strain.

Project description:CIMP (CpG island methylator phenotype) is an epigenetic molecular subtype, observed in multiple malignancies and associated with the epigenetic silencing of tumour suppressors. Currently, for most cancers including gastric cancer [GC], mechanisms underlying CIMP remain poorly understood. We sought to discover molecular contributors to CIMP in GC, by performing global DNA methylation, gene expression, and proteomics profiling across 14 gastric cell lines, followed by similar integrative analysis in 50 GC cell lines and 467 primary GCs. We identify the cystathionine beta-synthase enzyme (CBS) as a highly recurrent target of epigenetic silencing in CIMP GC. Likewise, we show that CBS epimutations are significantly associated with CIMP in various other cancers, occurring even in premalignant gastroesophageal conditions and longitudinally linked to clinical persistence. Of note, CRISPR deletion of CBS in normal gastric epithelial cells induces widespread DNA methylation changes that overlap with primary GC CIMP patterns. Reflecting its metabolic role as a gatekeeper interlinking the methionine and homocysteine cycles, CBS loss in vitro also causes reductions in the anti-inflammatory gasotransmitter hydrogen sulphide (H2S), with concomitant increase in NF-κB activity. In a murine genetic model of CBS-deficiency, preliminary data indicate upregulated immune-mediated transcriptional signatures in the stomach. Our results implicate CBS as a bi-faceted modifier of aberrant DNA methylation and inflammation in GC and highlights H2S donors as a potential new therapy for CBS-silenced lesions.

Project description:Recents studies in mice and humans demonstrated the relevance of H2S-synthesising enzymes (such as CTH, CBS and MPST) in adipose tissue physiology and preadipocyte differentiation into adipocytes. Here, we aimed to investigate the combined role of CTH, CBS and MPST in the preservation of adipocyte protein persulfidation and adipogenesis. Joint CTH, CBS and MPST gene knockdown was achieved treating fully human adipocytes with siRNAs against these transcripts (siRNA_MIX). Adipocyte protein persulfidation was analyzed by a mass spectrometry label-free quantitative approach coupled with a dimedone-switch method for protein labeling and purification. The proteomic analysis quantified 216 proteins with statistically different persulfidation levels in KD cells compared to control adipocytes. In fully differentiated adipocytes, CBS and MPST mRNA and protein levels were abundant, whereas CTH expression was very low. Of note, siRNA_MIX administration resulted in a significant decrease in CBS and MPST expression, without impacting on CTH. Dual CBS and MPST gene knockdown resulted in decreased expression of relevant genes for adipocyte biology, including adipogenesis, mitochondrial biogenesis and lipogenesis, but increased proinflammatory- and senescence-related genes, in parallel to a significant disruption in adipocyte protein persulfidation pattern. While among less persulfidated proteins, we identified several relevant proteins for adipocyte adipogenesis and function, among the most persulfidated, key mediators of adipocyte inflammation and dysfunction, but also some proteins that might have a positive role of adipogenesis were found. In conclusion, current study indicates that joint knockdown of CBS and MPST (but not CTH) in adipocytes impairs adipogenesis and promotes inflammation, possibly by disrupting the pattern of protein persulfidation in these cells, and suggesting that these enzymes were required for the functional maintenance of adipocytes.

Project description:Cystathionine Beta Synthase (CBS), an enzyme that utilizes a methionine precursor to generate glutathione (GSSH), has been implicated in the mitigation of ROS production in COPD lung. Additionally, post-translational modification analysis on mouse and human cells treated with cigarette smoke showed the unique presence of mono- and di-methylated histone H3 lysine 27 that was not seen in controls, suggesting that cigarette smoke could lead to loss of Polycomb Repressive Complex 2 (PRC2) activity. To elucidate CBS as a potential upstream target for PRC2 inhibition, we overexpressed CBS in Human Bronchial Epithelial Cells (HBECs), grew them as 2D cultures, then conducted bulk RNA seq analysis.

Project description:RNA sequencing of heterozygote or Tudor domain contian protein 6 (TDRD6) knockout round spermatid cells. Chromatoid bodies (CBs) are germ cell-specific organelles of largely unknown function. CBs harbor various RNA species, RNA-associated proteins and proteins of the tudor domain family such as TDRD6. Proteome analysis of purified CBs revealed components of the nonsense-mediated mRNA decay machinery such as UPF1. TDRD6 is essential for UPF1 localization to CBs, for UPF1-UPF2 interaction, and for assembly of UPFs and other RNA binding proteins into super-complexes. In absence of TDRD6, the association of some mRNAs with UPF1 is impaired, and the long 3â UTR-stimulated but not the exon junction complex-stimulated pathway of NMD is distorted. Reduced association of mRNAs with UPF1 correlated with increased stability and presence in polysome fractions, i.e. enhanced translational activity. Thus, we define CBs as sites of UPF1-dependent mRNA degradation and provide evidence for the requirement for NMD in spermiogenesis. This function of CBs depends on TDRD6-promoted assembly of mRNA decay enzymes within mRNPs. RNA was extracted from quadruplicate samples and libraries generated for sequencing using the NEBNext Ultra Directional RNA Library Prep Kit (New England Biolabs) at the Deep Sequencing Group SFB 655, Biotechnology Center of Technische Universität Dresden. After enrichment and XP bead (Agencourt AMPure Kit; Beckman Coulter, Inc.) purification, quality control was done using Fragment AnalyzerTM (Advanced Analytical). The bar-coded libraries were equimolarly pooled and subjected to 76 bp single-end sequencing on Illumina HiSeq 2000, resulting in an average of 33 million reads per sample.

Project description:The mechanisms underlying nuclear body (NB) formation and their contribution to genome function are unknown. We examined the non-random positioning of Cajal bodies (CBs), major NBs involved in spliceosomal snRNP assembly, and their role in genome organization. CBs are predominantly located at the periphery of chromosome territories at a multi-chromosome interface. Genome-wide chromatin conformation capture analysis (4C-seq) using CB-interacting loci revealed that CB-associated regions are enriched with highly expressed histone genes and U small nuclear and nucleoar RNA (sn/snoRNA) loci that form intra- and inter-chromosomal clusters. We observed a number of CB-dependent gene positioning events on chromosome 1. RNAi-mediated disassembly of CBs disrupts the CB-targeting gene clusters and suppresses the expression of U sn/snoRNA and histone genes. This loss of spliceosomal snRNP production resulted in increased splicing noise, even in CB-distal regions. We conclude that CBs contribute to genome organization with global effects on gene expression and RNA splicing fidelity.
