TranscriptomicsResponse of L. lactis faced to S. cerevisiae
The response of L. lactis to the presence of S. cerevisiae was analyzed during the exponential growth phase in fermentors in defined growth conditions. Although no growth kinetic difference was observed between the pure and mixed culture of L. lactis, the mRNA level of genes was significantly modifi...

GenomicsHigh-resolution mapping of transcription factor binding sites on native chromatin
Sequence-specific DNA-binding proteins including transcription factors (TFs) are key determinants of gene regulation and chromatin architecture. Formaldehyde cross-linking and sonication followed by Chromatin ImmunoPrecipitation (X-ChIP) and sequencing is widely used for genome-wide profiling of pro...

ProteomicsEvaluating protein crosslinking as a therapeutic strategy to stabilize SOD1 variants in a mouse model of familial ALS
Mutations in the gene encoding Cu-Zn superoxide dismutase 1 (SOD1) cause a subset of familial amyotrophic lateral sclerosis (fALS) cases. A shared effect of these mutations is that SOD1, which is normally a stable dimer, dissociates into toxic monomers that seed toxic aggregates. Considerable resear...

ProteomicsAnalysis of protein-DNA interactions in chromatin by UV induced cross-linking and mass spectrometry
Protein–DNA interactions are key to the functionality and stability of the genome. Identification and mapping of protein–DNA interaction interfaces and sites is crucial for understanding DNA-dependent processes. Here, we present a workflow that allows mass spectrometric (MS) identification of protei...

TranscriptomicsIntestinal Salmonella Typhimurium infection leads to miR-29a induced Caveolin 2 regulation [mRNA]
The host response to S.typhimurium infections in ileum was studied after infection of piglets. mRNA and miRNA expression studies were performed to identify interactions of miRNAs and regulated mRNAs in context of mammalian intestinal Salmonella infection using a piglet model. Intestinal samples (~ 2...

TranscriptomicsTranscription profiling of liver from Dahl salt sensitive (SS) rats and SS9BN consomic rats during hypoxia treatment
Examination of gene expression associated with hypoxia treatment of parental salt sensitive (SS) and consomic Brown Norway (SS9BN) rat strain. SS9BN rats are derived from introgression of chromosome 9 from BN rats into the SS genetic background.

TranscriptomicsInhibitors that block initiation of wall teichoic acid biosynthesis sensitize methicillin-resistant Staphylococcus aureus to beta-lactams
Methicillin resistance in Staphylococcus aureus depends on the production of mecA, which encodes penicillin-binding protein 2A (PBP2A), an acquired peptidoglycan transpeptidase with reduced susceptibility to beta-lactam antibiotics. Here, we show that preventing the expression of wall teichoic acids...

ProteomicsAge-Related Disruption of the Proteome and Acetylome in Mouse Hearts Correlates with Differential Loss of Function that is Attenuated by SS-31 and NMN
We analyzed the effects of aging on protein abundance and acetylation, as well as the ability of the mitochondrial-targeted drugs SS-31 and NMN to reverse age-related changes, in mouse hearts. Both drugs had a modest effect on restoring the abundance and acetylation of proteins that are lost with ag...
