Gene circuits in live cells can perform complex computations Biology Diagrams An emerging and critical feature of designing circuits for these applications is their genetic stability. 41 Introducing gene circuits into host cells can impose a fitness cost by creating a metabolic or resource burden or from expression of a toxic protein product. 42, 43, 44 Cells harboring mutations that abrogate circuit function can To this end, the development of in vitro cell-free methods to debug circuits will be valuable for designing circuits that are robust to these changes 211,212,213,214,215,216,217,218,219,220. Cells use genetic circuits of interacting genes and proteins to implement diverse functions including growth and division, signaling, and differentiation. The cell cycle is one of the foundations of life; successfully replacing it with a synthetic module represents a fundamental advance in synthetic biology.
The Genetic Circuit Is Supported by TF Binding Profiles. The targets our model predicted for most TFs are strongly supported by chromatin cell-cycle phase) rather than discrete types, we performed PCA on WT K562 cells, scored the cells from the Perturb-seq experiment against those PC scores, and introduced the state PC scores as covariates.
Designing cell function: assembly of synthetic gene circuits for cell ... Biology Diagrams
Creating a multi-cell-cycle deferral time with continuous (nonpulsatile) genetic circuits is challenging in proliferating cells, as dilution of cellular components during cell growth forces most protein concentrations to relax to their steady-state values over a time scale of about one cell cycle or faster.
Genetic circuits control diverse biological behaviors. For very unstable proteins, whose half-life is much smaller than the cell cycle period, dilution may be negligible. In bacteria, mRNA half-lives (1-10 min, typically) are much shorter than protein half-lives. In eukaryotic cells this is not necessarily true (mRNA half-lives can be many
