For this reason and given that the lack of ICT competence is likely to induce refusal of CBA, in the following analysis we will treat PSTRE proficiency as a single outcome, without distinguishing between the two sources.
In LB medium cells normally are poorly competent, and the induction of competence under these conditions demonstrates that the system is able to induce competence under non-competence stimulation conditions.
Once in the chromatin, PS-I κB α facilitates the recruitment of polycomb repressive complex 2 to gene promoters and dictates their competence to be induced following TNF α stimulation, thus establishing a mechanistic link between inflammatory signals and skin homeostasis.
This indicates that, although B. licheniformis DSM13 contains the core ComK-regulon required for competence development [23], comK induction alone is not sufficient to induce competence in this strain under our experimental conditions.
Cultures were incubated at 37°C for 100 min to induce competence prior to addition of 1 µg DNA to appropriate samples.
Furthermore, we checked for the loss of the ability to induce competence as measured by PcomG-GFP fluorescence upon induction with IPTG, using the microtitreplate reader as described above.
To assess the functional competence of this TCR to induce cytokine responses, mature human peripheral blood mononuclear cell (PBMC -derived CD8+ T cells were transduced and stimulated with an irradiated SL9 PBMC -derivedd HLA-A*0201+ professional antigen presenting CD8+ line.
The PM1665 homologue in Haemophilus influenzae (HI1008) has been designated ComE1 by Redfield et al. [8] on the basis of experimental evidence demonstrating that this gene is up-regulated almost 300-fold in cells that have been starved to induce competence.
To overcome this TR insufficiency, we chose to treat tadpoles with a brief, weak pulse of T3 to induce competence to respond to a later exposure to TH.
For induction of differentiation the cells were grown to confluence and then kept in the above media without EGF for 48 h to induce competence.
