  • A number of new loci were also implicated in Triclosan resistance and the predicted phenotypes for a selection of these were validated experimentally and results showed high consistency with predictions. (biorxiv.org)
  • For example, even if comprehensive insertion libraries are produced, it is inevitable that some genes, especially the shortest ones, could elude insertion and be spuriously annotated as essential, while transposon insertions that occur at gene ends and do not fully inactivate the function could lead to genes being incorrectly classified as non-essential.

  • We screened selected genomic regions using libraries derived from randomly fragmented bacterial artificial chromosomes (BACs) to determine enhancer activities (Arnold 2013) and enhancer-activity changes upon cofactor inhibition (Rathert 2015). (starklab.org)

  • 2005). There are 28 sigma factor genes in in contrast with 13 reported in (Cole et?al. (healthyguide.info)
  • Sigma factors reversibly associate with RNA polymerase and allow them to specifically direct the expression of specific set of genes. (healthyguide.info)
  • The composition of the 'bacteriocin/immunity region' of the blp cassette was highly variable: one cassette possessed six bacteriocin genes and eight putative immunity genes, whereas another cassette had only one of each. (biomedcentral.com)
  • My work has made substantial progress on defining the resistance mechanisms associated with these genes. (cornell.edu)
  • The molecular mechanisms of ecdysone-regulated metamorphosis and developmental timing have been studied extensively in Drosophila. (sdbonline.org)
  • In fact, amplification of genes by over replication of certain regions of DNA is one of the primary mechanisms by which cancer cells become resistant to drug therapy. (nih.gov)

  • S. aureus infection is mediated via the agr locus by the release of several virulence agents and influencing biofilm formation. (springeropen.com)
  • The well-known core directing locus of the Gram-positive bacterial QS system is the accessory gene regulator ( Agr ) that has been considerably explored in S. aureus (El-gamal et al. (springeropen.com)
  • Diet-induced obesity led to altered acetylation of lysine 27 on histone H3 (H3K27ac) and to altered monomethylation of lysine 4 on histone H3 (H3K4me1) at numerous loci, with concomitant changes in the expression of genes that were functionally relevant to intestinal cancers.

  • Expression of genes that regulate mitochondrial biogenesis, substrate utilization, and oxidative phosphorylation (OXPHOS) were determined. (omicsdi.org)
  • The interactions between AmtR and the promoter regions of the three operons were confirmed by electrophoretic mobility shift assays (EMSAs). (frontiersin.org)
  • BsaN orchestrates the temporal and spatial expression of virulence determinants during progression through the intracellular lifecycle, EPZ5676 mw promoting endosome escape and possibly evasion of autophagy through activation of T3SS3 effector loci, facilitating cell-cell spread by activation of T6SS1 and the bim intracellular motility loci, and suppressing cellular immunity via the action of the TssM ubiquitin hydrolase.

  • DNA replication is the primary event that regulates cellular and viral proliferation. (nih.gov)
  • As a result, bacterial survival often depends upon the ability of cells to adjust the cell membrane in response to environmental stress. (cornell.edu)
  • Unlike antibacterials that aim to inhibit cell growth, antivirulence therapies are based on the inhibition of bacterial virulence. (nature.com)
  • Northern blot analysis also showed that the fsr genes were highly expressed in post-exponential phase during growth and that the expression of fsr genes were cell-density dependent and could be induced by a secreted inducer(s) in the supernatant of OG1RF cultures. (uth.edu)
  • Cell-type specific enhancers drive differential gene expression, hence, identifying such enhancers can be of utmost importance to our understanding of development and differentiation. (starklab.org)
  • Importantly, cell type-specific gene expression levels were correlated to the combined activities of the flanking enhancers within each cell type and across cell types, which links differential gene expression to differences in enhancer activity and demonstrates that ectopic assays can accurately assess cell type-specific enhancer activities. (starklab.org)
  • As a graduate student with Julius Adler, I identified the basal body of the bacterial flagellum, develop methods for its purification, and elucidate its fine structure and specific attachments to the bacterial cell envelope. (nih.gov)
  • Given the considerable time needed to activate new genes and/or de novo synthesize mRNA, the translation of existing mRNAs provides the necessary plasticity for the cell to selectively and rapidly respond to stress [1] , [2] . (prolekarniky.cz)
  • Low shear stress up-regulates expression of vascular cell adhesion molecule 1 (VCAM-1), while increased shear stress can lead to increased gene expression of intercellular adhesion molecule 1 (ICAM-1). (medscape.com)
