Increased virulence mediated by subinhibitory concentrations of Cefotaxime (CTX)

ABSTRACT: Identification of mutants under negative selection mediated by a non-lethal concentration of CTX Two condition experiment, transposon library exposed during 3 h to CTX vs. Non-exposed control transposon library (paralelly growing). Biological replicates: 3 control, 3 antibiotic exposed cells, independently grown and harvested. One replicate per array.

mRNA-seq analyses for the differentially expressed genes (DEGs) among Con, NF VM-astrocytes, Ctx-astrocytes, and control Ctx-NPCs

Project description:To gain further molecular insight into the observed astrocyte functions, we performed RNA-sequencing (RNA-seq) analysis of the differentiated Ctx-NPCs (control), Ctx-astrocytes and VM-astrocytes used in the co-culture and CM experiments. The genes that are differentially expressed (DEGs) in Ctx-astrocytes compared to differentiated Ctx-NPCs (FPKM>1, log2>1) significantly overlapped with DEGs in VM-astrocytes compared to differentiated Ctx-NPCs

Transcription profiling of mouse liver genomic responses to ciguatoxin (P-CTX-1)

Project description:Ciguatoxins (CTX) are polyether neurotoxins responsible for ciguatera, the most common fish-borne food poisoning in humans. This study characterizes the global transcriptional response of mouse liver to a symptomatic dose (0.26 ng/g) of the highly potent Pacific ciguatoxin-1 (P-CTX-1). At 1 h post exposure 2.4% of features on a 44K whole genome array were differentially expressed (p â?¤ 0.0001), increasing to 5.2% at 4 h and decreasing to 1.4% by 24 h post-CTX exposure. Early gene expression was likely influenced prominently by an acute 4 Â°C decline in core body temperature by 1 h, which resolved by 8 h following exposure. Cytochrome P450s were of particular interest due to their role in xenobiotic metabolism. Twenty-seven genes, mostly members of Cyp2 and Cyp4 families, showed significant changes in expression. Many Cyps underwent an initial down-regulation at 1 h but were quickly and strongly up-regulated at 4 and 24 h post exposure. In addition to Cyps, increases in several glutathione S-transferases were observed, an indication that both phase I and phase II metabolic reactions are involved in the hepatic response to CTX in mice. Experiment Overall Design: Individual C57/BL6 mice (n=3) exposed to 0.26 ng/g P-CTX-1 ip for 1, 4, or 24 h were compared to pooled time-matched controls (n=3). The triplicate arrays at each time point included a dye swap.

Profiling of glycerol- and CTX-induced models of muscle regeneration in mice

Project description:Utilizing glycerol and cardiotoxin (CTX) injections in the tibialis anterior muscles of M. musculus provides models of skeletal muscle damages followed by skeletal muscle regeneration. In particular, glycerol-induced muscle regeneration is known to be associated with ectopic adipogenesis. We characterized genome-wide expression profiles of tibialis anterior muscles from wild-type mice injured by either glycerol or CTX injection. Our goal was to detect gene expression changes during the time course of glycerol-induced and CTX-induced muscle regeneration models, that can lead to ectopic adipocyte accumulation. Tibialis anterior muscle of 12 week old wildtype C57BL/6J male mice injected i.m with either glycerol or CTX were collected 3, 7, 14 or 21 days after injection. 6 biological replicates were used for each time points. Please note that a few replicate samples did not pass QC test, thus, were removed from the submission. Unchallenged tibialis anterior muscles from a group of 5 wildtype C57BL/6J mice were also as a control. Total RNA was extracted, QCed and hybridized to Affymetrix microarrays.
