Project description:We report the 3.2-Mb draft genome sequence of Brevundimonas denitrificans strain TAR-002T, isolated from deep-sea floor sediment. The draft genome sequence of strain TAR-002T consists of 3,231,216 bp in 44 contigs, with a G+C content of 68.47%, 3,866 potential coding sequences (CDSs), 3 rRNAs, and 45 tRNAs.
Project description:Transcriptional profiling of Paracoccus denitrificans PD1222 wild type grown to mid-exponential phase in minimal media with either 13 uM (Cu-H) or 0.5 uM (Cu-L) Cu regimes. The goal was to define the effects of Cu-limitation on denitrification genes Two growth conditions, three biological replicates of each condition. Each sample hybridised in a two-channel hybridization against Paracoccus denitrificans genomic DNA as the comparator/reference, which also acted as a control for spot quality. Cu-concentration 13 uM (Cu-H) versus 0.5 uM Cu (Cu-L) in anaerobic growth conditions.
Project description:Bromodomain and extraterminal domain (BET) proteins have emerged as therapeutic targets in multiple cancers, including the most common primary adult brain tumor glioblastoma (GBM). Although several bet inhibitors have entered clinical trials, few are brain penetrant. We have generated UM-002, a novel brain penetrant BET inhibitor that reduces GBM cell proliferation in vitro and in a human cerebral brain organoid model. Since UM-002 is more potent than other BET inhibitors, it could potentially be developed for GBM treatment. Furthermore, UM-002 treatment reduces the expression of cell-cycle related genes in vivo, and reduces the expression of invasion related genes within the non-proliferative cells present in tumors as measured by single cell RNAsequencing. These studies suggest that BET inhibition alters the transcriptional landscape of GBM tumors, which has implications for designing combination therapies. Importantly, they also provide an integrated dataset that combines in vitro and ex vivo studies with in vivo single-cell RNA-sequencing to characterize a novel BET inhibitor in GBM.

Project description:The alphaproteobacterium Paracoccus denitrificans Pd1222 has two different, yet functionally redundant acetyl-CoA assimilation routes: the Ethylmalonyl-CoA pathway (EMCP) and the glyoxylate cycle (GC). The EMPC and the GC each tightly control the balance between catabolism and anabolism by shifting flux away from the oxidation of acetyl-CoA in the tricarboxylic acid (TCA) cycle towards biomass formation. RamB (encoded by Pden_1365), a member of the ScfR family, is a transcriptional regulator in P. denitrificans Pd1222 that controls expression of GC. To analyze the role of RamB in the coordinated regulation of metabolic plasticity, we analyzed the global transcriptome of P. denitrificans Pd1222, as well as the ramB-deletion strain during mid-exponential growth phase on defined minimal medium with acetate or succinate as carbon sources.
Project description:Transcriptome profiles of an aerobic photosynthetic bacterium Roseobacter denitrificans OCh114 grown under different oxygen tension and light irradiation conditions were determined by NimbleGen Prokaryotic Expression array (12x135K).
Project description:Transcriptional profiling of Paracoccus denitrificans PD1222 wild type incubated in continuous culture (continuous culture (CSTR)) in minimal media with aerobic or anaerobic conditions. The goal was to define the core respiratory genes.
