On the basis of our model, a genetic system such as the repressilator would not oscillate in a batch reaction. ... We achieved dilution-dependent steady-state mRNA and protein levels for 30 h (Fig. 2B). WebThe results above show it should be possible to systematically learn gene regulatory connections from stochastic variation in steady-state cells, provided one can measure transcriptome-wide mRNA levels at pairs of time points in individual cells with sufficient sensitivity and power. We now turn to how one might implement the theory in practice.

"WebMBP mRNA levels, which decline by approximately 30% but are maintained throughout adulthood. Variant MBP proteins are produced by alternative splicing (deFerra et al., 1985), but the 59 and 39 UTRs are identical across all isoforms. In the QKv mouse, steady-state MBP is vastly reduced to approximately 5% of normal (Roth et al., 1985). " - Steady-state mrna levels
