Transcriptomic changes associated with growth of Mycobacterium tuberculosis H37Rv wild-type strain and ∆prpR mutant in mineral medium supplemented with cholesterol as the sole carbon source or standard medium supplemented with vitamin B12.

Project description:RNA-Seq results accompanying submission of a manuscript: "Cholesterol-dependent transcriptome remodeling reveals new insight into the contribution of cholesterol to Mycobacterium tuberculosis pathogenesis" describing the role of cholesterol and vitamin B12 in shaping the transcriptome of the Mycobacterium tuberculosis H37Rv and M. tuberculosis ∆prpR - propionate regulator (PrpR) mutant. Next generation sequencing results are provided in three independent biological replicates for each strain growing in three different media - minimal medium with glycerol or cholesterol as the sole carbon source and standard 7H9/10% OADC medium. The influence of vitamin B12 on M. tuberculosis transcriptome was analysed on 7H9/10% OADC medium supplemented with B12. The study allowed us to re-establish the list of genes potentially involved in cholesterol metabolism. We further proposed a novel regulatory function of vitamin B12 and PrpR, a propionate regulator, in coordinated cholesterol breakdown metabolite dissipation and virulent phenotype induction. Finally, we demonstrated that a key role of cholesterol in Mtb metabolism is not only providing carbon and energy but also inducing a transcriptome remodeling program that helps in developing tolerance to the unfavorable host cell environment.

Impact of the vitamin B12 on the transcriptional regulation of the Mycobacterium tuberculosis Complex

Project description:The transcriptome in response to vitamin B12 was interrogated in three M. tuberculosis Complex species: M. tuberculosis H37Rv, M. tuberculosis GC1237, and M. bovis AF2122/97. Examination of the core B12 transcriptome resulted in a robust differential regulation of 7 genes in the three species analysed

Microarray analysis of liver and mammary gland biopsies of dairy cows supplemented with vitamins B9 and B12 alone or in combination

Project description:Data from one animal from B9_B12 group (Cow 31) were not taken into account for the liver samples Treated animals were compared to control (non supplemented cows) Twenty four multiparous Holstein cows were assigned to 6 blocks of 4 animals according to their 305-d milk production during the previous lactation to one of the following treatments: injections saline 0.9% NaCl (Ctl); folic acid (B9); vitamin B12 (B12) or folic acid and vitamin B12 (B9_B12). Biopsies of hepatic (foie for liver) and mammary (mam for mammary gland) tissues were taken from these 24 cows. Microarray analyses were performed on samples from both tissues for 3 animals per treatment in CTL, B9 and B9_B12 and for 4 animals in B12 treatment. Data for hepatic tissue of animal 31 (group B9_B12) were not included. For both tissues, treated animals were compared to control.

Effect of amino acid availability on vitamin B12 production in Lactobacillus reuteri

Project description:Recent functional genomics and genome-scale modeling approaches indicated that B12 production in Lactobacillus reuteri could be improved by medium optimization. Here we show that a series of systematic single amino acid omissions could significantly modulate the production of B12 from nearly undetectable levels (by isoleucine omission) to 20-fold higher than previously reported through omission of cysteine. We analyzed by cDNA microarray experiments the transcriptional response of L. reuteri to the medium lacking cysteine. These results supported the observed high B12 production and provided new avenues for future improvement of production of vitamin B12. Keywords: cell type comparison

RNA-seq of Senegalese sole testis: comparison between fish fed a control and an algae-supplemented diet

Project description:Senegalese sole males born and raised in captivity (F1 males) do not spawn naturally and typically display lower gamete quality when compared with wild individuals. Broodstock nutrition is an important aspect when dealing with reproduction because it influences not only fish health, but also gamete and progeny quality. The usage of dietary algae antioxidants to improve fish reproduction is under-explored, especially in terms of the male reproductive system. In this experiment, 6 % of a blended meal of Phaeodactylum tricornutum and Gracilaria gracilis was incorporated in Senegalese sole broodstock feed, to evaluate the effects on sperm quality of F1 males throughout the breeding season. RNA-seq was employed to assess differences in the gonadal tissue of fish fed the algae supplemented diets.

Effects of vitamin B12 on the gene expression of PAO1 under anaerobic growth conditions

Project description:Pseudomonas aeruginosa undergoes cell elongation and forms robust biofilms during anaerobic respiratory growth using nitrate (NO3-) as an alternative electron acceptor. Understanding the mechanism of cell shape change induced upon anaerobiosis is crucial to the development of effective treatments against P. aeruginosa biofilm infection. Anaerobic growth of PAO1 reached higher cell density in the presence of vitamin B12, an essential coenzyme of class II ribonucleotide reductase. In addition, cell morphology returned to a normal rod shape. These results suggest that vitamin B12, the production of which was suppressed during anaerobic growth, can restore cellular machineries for DNA replication and therefore facilitate better anaerobic growth of P. aeruginosa with normal cell division. We used microarray to elucidate the global gene expression profiles underlying vitamin B12-induced changes in bacterial cell shape and growth-associated properties. Gene expression profiles of PAO1 grown in LBN (LB+NO3-) or LBN supplemented with 1 microM vitamin B12 are compared.

RNA-seq for understanding effects of vitamin B12 removal on astrocyte culture

Project description:Astrocytes express a vitamin B12 uptake receptor, CD320/TCblR, that is regulated by S1P1 signaling. In search of genes controlled under B12 deficiency in astrocytes, we employed RNA-seq using RNA of astrocytes cultured in normal or B12 deficient media.
