Project description:Pseudomonas sp. strain CK-NBRI-02 is a potential plant growth-promoting Gram-negative rhizobacterium isolated from the rhizosphere of maize plants growing in fields in Srinagar, Jammu, and Kashmir, India. Here, we report a 5.25-Mb draft assembly of the genome sequence of Pseudomonas sp. strain CK-NBRI-02 with an average G+C content of 62.47%.
Project description:Here, we report the first complete genome sequence of the Mycobacterium intracellulare clinical strain MOTT-02, which was previously grouped in the INT2 genotype of M. intracellulare. This genome sequence will serve as a valuable reference for improving the understanding of the disparity in the virulence and epidemiologic traits between M. intracellulare genotypes.
Project description:Bacillus thuringiensis (Bt) is widely used to control agricultural and forestry pests, though there are only a few available complete genome sequences of the Bt reference strain. Here, we report the complete genome sequence of B. thuringiensis serovar rongseni reference strain SCG04-02, which is toxic to Plutella xylostella.
Project description:Investigation of whole genome gene expression differences in a full (nine-gene) Lsr locus knockout strain compared to the wild-type strain (CZ4126/02). This Lsr mutant is unable to import the autoinducer-2 (AI-2) quorum sensing molecule nor mediate any potential LsrR-based transcriptional regulation.
Project description:Adoptive immunotherapy of tumors with T cells specific for the cancer-testis antigen NY-ESO-1 has shown great promise in preclinical models and in early stage clinical trials. Tumor persistence or recurrence after NY-ESO-1-specific therapy occurs, however, and the mechanisms of recurrence remain poorly defined. In a murine xenograft model of NY-ESO-1(+) multiple myeloma, we observed tumor recurrence after adoptive transfer of CD8(+) T cells genetically redirected to the prototypic NY-ESO-1157-165 peptide presented by HLA-A*02:01. Analysis of the myeloma cells that had escaped from T-cell control revealed intact expression of NY-ESO-1 and B2M, but selective, complete loss of HLA-A*02:01 expression from the cell surface. Loss of heterozygosity (LOH) in the major histocompatibility complex (MHC) involving the HLA-A locus was identified in the tumor cells, and further analysis revealed selective loss of the allele encoding HLA-A*02:01. Although LOH involving the MHC has not been described in myeloma patients with persistent or recurrent disease after immune therapies such as allogeneic hematopoietic cell transplantation (HCT), it has been described in patients with acute myelogenous leukemia who relapsed after allogeneic HCT. These results suggest that MHC loss should be evaluated in patients with myeloma and other cancers who relapse after adoptive NY-ESO-1-specific T-cell therapy.
Project description:To discover novel regulators that influence avermectin biosynthesis, comparative transcriptome analysis between wild-type strain ATCC31267 and avermectin overproducing strain 76-02-e were performed to reveal some differentially expressed genes.
Project description:We report the draft genome sequence of a marine bacterium, Bacillus sp. strain 007/AIA-02/001, isolated from the marine sponge Coelocarteria singaporensis, obtained from water off the coast of Singapore. The analysis of the bacterial genome using the bioinformatics tool antiSMASH 4.0.2 showed the presence of a number of unique natural product biosynthetic pathways.
Project description:To discover novel regulators that influence avermectin biosynthesis, comparative transcriptome analysis between wild-type strain ATCC31267 and avermectin overproducing strain 76-02-e were performed to reveal some differentially expressed genes. Global gene expression in ATCC31267 and 76-02-e was measured at day 2 (early exponential phase) or day 6 (stationary phase), respectively. Three independent experiments for 76-02-e and one for ATCC31267 were performed at each condition.
Project description:Investigation of whole genome gene expression differences in a full (nine-gene) Lsr locus knockout strain compared to the wild-type strain (CZ4126/02). This Lsr mutant is unable to import the autoinducer-2 (AI-2) quorum sensing molecule nor mediate any potential LsrR-based transcriptional regulation. WT and Lsr-KO strains were grown in two different media to two or three different time-points. RNA was extracted from these sampling conditions in two separate cultures (biological replicates). Each of these RNA samples was run on two different H. influenzae supragenome arrays (technical replicates). 3-13 probes represent each subcluster (gene) and two replicate probe sets are included on each custom NTHi supragenome chip. Thus, under each sampling condition, 8 separate values are obtained per strain and used for WT:Lsr-KO comparisons.
