This is a book that can be read at two levels: either a qualitative understanding of the behavior or at a more detailed mathematical level. I personally found the qualitative insights very interesting, even quite exci "An Introduction to Systems Biology: Design Principles of Biological Circuits" provides a great deal of insight into how the connections of gene and protein interaction networks provide the necessary robustness and control to achieve cellular function in the face of chemical noise.

I personally found the qualitative insights very interesting, even quite exciting. For this reason, I have decided to give a detailed summary of some of the qualitative findings to promote a broader appreciation for these ideas outside of their mathematical context. Fortunately, these ideas were extremely well organized, with roughly a chapter for every bullet point below. How does a cell control the conditions in which a given gene is allowed to express a protein?

The work behind this book finds out by first assembling the network of activations and repressions at work in a cell, abstracting away biochemical particulars.

Then, it looks to see what motifs structural patterns occur much more and less frequently in those networks as compared to networks assembled by chance. Each motif is then examined for what function it then provides. Let us now talk about some common motifs found with this approach.

This allows for "a" to be activated very quickly, with the confidence that it will regulate its own level.

Prerequisites

This from minimal information about the nature of the interactions happens because topological and physical—chemical constraints involved, and that a universal set of design principles would ap- prevent some interactions and favor others, and because the pro- ply to all realizations of each motif.

Unfortunately, these expec- cess whereby new genes are created—often gene duplication, with tations may be over-optimistic.

Many network motifs can the daughter gene initially inheriting the interactions of the parent perform several different functions, depending on context, on gene—further biases the distribution of interaction patterns. This is illustrated by the incoher- properties severely limit the reactions in which it can participate, ent type 2 feed-forward-loop FFL, Fig. This problem of evolutionary interpretation becomes acute the action of each transcription factor, Wall et al.

This repertoire ferent types of networks that are subject to distinct constraints and of behaviors allows these circuits to alternatively provide various bias.

Compounding the problem, transcription net- representation of the patterns with respect to more-realistic null works do not represent a totally autonomous layer of regulation, models that take all the constraints and bias above into account. A second concern is that statistics of interaction patterns may actually represent complex processes, inputs to the network may be biased by the presently incomplete and fairly unreliable motifs may be correlated, and there may be external i.

However, non-motifs do not necessarily regularities. They may just provide more unique ogy. Indeed—and irrespective of the added value of statistical comparisons with respect to a question- References able null model—the results and discussions in the book convinc- [1] L.

Each motif is then examined for what function it then provides. Let us now talk about some common motifs found with this approach. This allows for "a" to be activated very quickly, with the confidence that it will regulate its own level.

This acts to filter out transient changes in "a". If both "a" and "b" are required to activate "c", then "c" will not be expressed if "a" isn't activated long enough to also activate "b".

Similarly, if either "a" or "b" is sufficient to activate "c", then temporary gaps in the production of "a" will not affect the production of "c", due to the presence of "b".

Design principles of biological circuits

This allows for an initial pulse of "c" upon "a", but that is then brought under control by "b". Varying responses to a common input can create a first-in, last-out stack of activation.

Different sensitivities to the "a" and "b" of coherent feed-forward loops can create first-in, first-out queues as "a" falls to smaller concentrations with respect to "b". The second half of the book turns to engineering considerations of robustness and cost optimization.Klipp, R. This repertoire ferent types of networks that are subject to distinct constraints and of behaviors allows these circuits to alternatively provide various bias.

For anyone who wants to understand how a living cell works, but thought they never would, this book is essential. One answer is that an unbound state can be activated accidentally by chemically similar proteins.

Network motifs in developmental, signal transduction, and neuronal networks Ch. How does the cell send correct signals, transcribe the right proteins, and express the right genes for as little management overhead as possible?

Certainly, given the above discussion about optimization this caught me by surprise: why bear the cost of producing a regulatory protein most of the time?
