Example sentences for: acta

How can you use “acta” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • Microarray analysis of the actA time courses revealed that the host transcriptional responses were remarkably similar to those observed during infection with the wild-type strain.

  • prfA mutant bacteria could still be seen associated with cells by phase-contrast microscopy at 4 hours post-infection (Figure 1d), albeit at much lower levels than wild-type or actA bacteria as they were no longer replicating.

  • To this end, we carried out similar 8-hour time courses with an isogenic L. monocytogenes strain deficient in actA (DP-L1942, Δ actA ), which is unable to nucleate actin polymerization and hence has no capacity for intracellular motility and intercellular spread [ 30].

  • It is likely that differences in the transcriptional program would emerge at later stages of infection, as wild-type and actA bacteria replicate and kill the cells, and prfA do not.

  • The prfA gene codes for a transcriptional regulator, which controls the virulence genes hly, plcA, plcB, mpl and actA , as well as negatively regulating itself [ 31, 32].
