(a) Schematic representation on the intrinsic (blue) and extrinsic (yellow) noise in the NF-kB method. (b) Distinctive noise models fit single-cell information. Shown will be the comparison in between simulation (300 cells) of extrinsic noise (through the distributed A20 transcription price) and intrinsic noise (by means of the stochastic regulation of A20 gene activity) model, and the data for TNFa pulses at 70 min interval. (c) Simulated single-cell traces (shown as NF-kB:IkBa complex levels, in distinctive coloured lines) for different noise models. TNFa applied at two 70 min intervals separated by 4 h equilibration phase (as depicted with blue bars). (d) C9 cell responses to equilibrated TNFa pulses (as in c). Shown are suggests (in green, .d.) of normalized single-cell total IkBa-GFP intensities in nine non-responsive (left panel) and 32 responsive cells (correct panel) to second (p2) and fourth (p4) pulse. (e) Comparison between model simulations plus the information for equilibrated TNFa pulses. Simulation performed with 300 cells assuming intrinsic (in yellow) and extrinsic (in blue) noise (as in c). Information from d presented in fraction of cells (total 79) responding to second ( sirtuininhibitorp2, sirtuininhibitorp4), fourth ( sirtuininhibitorp2, sirtuininhibitorp4) or each second and fourth ( sirtuininhibitorp2, sirtuininhibitorp4) pulses. (f) Principal element evaluation of single-cell information from d. For every cell, 140 min sub-ENA-78/CXCL5 Protein manufacturer trajectories corresponding to two stimulation phases had been considered (depicted with symbols SPARC Protein site connected with distinct colour lines). Responsive and non-responsive cell clusters outlined with dashed lines. (g) Daughter cell analysis in response to two TNFa pulses at 70 min interval. Time from cell division to stimulation recorded. (h) Representative daughter C9 cell responses (as in g): Cells (indicated with stars, IkBa-eGFP intensities shown) respond towards the 1st (depicted at ten min soon after stimulation), as well as towards the second TNFa pulse (at 80 min following get started on the experiment). Scale bar, 20 mm. (i) Representative daughter cells trajectories (in the experiment in g). (j) Fractions of homogenous and heterogeneous daughter cells responses. 56 pairs stimulated as in g, stratified by patterns of the IkBa-eGFP signal.NATURE COMMUNICATIONS | 7:12057 | DOI: ten.1038/ncomms12057 | www.nature/naturecommunicationsNATURE COMMUNICATIONS | DOI: ten.1038/ncommsARTICLEonly modest raise (o50 ) in response to TIT compared with TTT stimulation (with A20 and IkBa highest with two-fold and 1.4-fold change, respectively). Notably, all the signalling molecules exhibited alterations more than two-fold with CCL1, CXCL2, IL8 and TNFAIP6 higher than five-fold (Fig. 6f). In contrast, comparison involving single TNFa and IL-1b pulses did not show a difference inside the expression of those genes (see Supplementary Fig. 34e and Supplementary Information 1).
