This book was released on 2013 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies in the past decade have established gene expression as an inherently variable process. Accompanying this exciting finding is a fundamental question: how do physiological events, such as cell fate specification, proceed so robustly in the face of gene expression variability? In this thesis, I took a fresh attack at this question by examining the control of variability in the context of the stereotyped development of the nematode C. elegans. Specifically, I focused on the regulation of a Hox gene by the Wnt signaling pathway in a single C. elegans neuroblast. Analogous to vertebrate neural crest cells, Hox gene expression determines the migratory direction and the subsequent fate choices of cells that descend from the original neuroblast. Intrigued by the earlier observation that perturbation to Wnt signaling disrupts the wild-type stereotypy in migratory decision, I speculated that variable gene expression may underlie the partial penetrance in the mutants and subsequently questioned what mechanism safeguards against variability in the wild type. Combining single-cell transcript counting with genetic manipulation, I quantified the variability in Hox gene expression in the Q neuroblasts in both the wild type and a series of Wnt signaling mutants. Interestingly, I observed increased expression variability in a number of mutants and an overall complex relationship between expression variability and mean expression level. Distinct features in the gene expression profile embarked me on a search for network interactions, leading to the discovery of multiple novel feedback loops within the Wnt pathway. Applying computational network inference, I revealed a network of interlocking positive and negative feedback loops, which I subsequently show to have a topological advantage in dampening stochastic noise in gene expression.

Book excerpt: Genetically identical cells and organisms growing in homogenous environmental conditions can show significant phenotypic variation. Furthermore, mutations often have consequences that vary among individuals (incomplete penetrance). Biochemical processes such as those involved in gene expression are subjected to fluctuations due to their inherent probabilistic nature. However, it is not clear how these fluctuations affect multicellular organisms carrying mutations and if stochastic variation in gene expression among individuals could confer any advantage to populations. We have investigated the consequences of stochastic gene expression using the nematode Caenorhabditis elegans as a model. Here we show that inter-individual stochastic variation in the induction of both specific and more general buffering systems combine to determine the outcome of inherited mutations in each individual. Also, we demonstrate that genetic and environmental robustness are coupled in C. elegans. Individuals with higher induction of stress response are more robust to the effect of mutations, however they incur a fitness cost, thus suggesting that variation at the population level could be beneficial in unpredictable environments.

Available in PDF, EPUB and Kindle. Book excerpt: Since the discovery of the gene for green fluorescent protein (GFP), derived from jellyfish, this protein that emits a green glow has initiated a revolution in molecular biosciences. With this tool, it is now possible to visualize nearly any protein of interest in any cell or tissue of any species. Since the publication of the first edition, there have been tremendously significant technological advances, including development of new mutant variants. Proteins are now available in yellow and blue, and Novel Fluorescent Proteins (NFPs) have expanded their utility in developing biosensors, biological markers, and other biological applications. This updated, expanded new edition places emphasis on the rise of NFPs, including new chapters on NFP properties with detailed protocols, applications of GFPs and NFPs in industry research, and biosensors. This book provides a solid theoretical framework, along with detailed, practical guidance on use of GFPs and NFPs with discussion of potential pitfalls. The expert contributors provide real examples in showing how to tailor GFP/NFP to specific systems, maximize expression, and enhance detection.

Available in PDF, EPUB and Kindle. Book excerpt: Sexual reproduction is a fundamental aspect of life. It is defined by the occurrence of meiosis and the fusion of two gametes of different sexes or mating types. Sex-determination mechanisms are responsible for the sexual fate and development of sexual characteristics in an organism, be it a unicellular alga, a plant, or an animal. In many cases, sex determination is genetic: males and females have different alleles or different genes that specify their sexual morphology. In animals, this is often accompanied by chromosomal differences. In other cases, sex may be determined by environmental (e.g. temperature) or social variables (e.g. the size of an organism relative to other members of its population). Surprisingly, sex-determination mechanisms are not evolutionarily conserved but are bewilderingly diverse and appear to have had rapid turnover rates during evolution. Evolutionary biologists continue to seek a solution to this conundrum. What drives the surprising dynamics of such a fundamental process that always leads to the same outcome: two sex types, male and female? The answer is complex but the ongoing genomic revolution has already greatly increased our knowledge of sex-determination systems and sex chromosomes in recent years. This novel book presents and synthesizes our current understanding, and clearly shows that sex-determination evolution will remain a dynamic field of future research. The Evolution of Sex Determination is an advanced, research level text suitable for graduate students and researchers in genetics, developmental biology, and evolution.

Available in PDF, EPUB and Kindle. Book excerpt: Life history theory seeks to explain the evolution of the major features of life cycles by analyzing the ecological factors that shape age-specific schedules of growth, reproduction, and survival and by investigating the trade-offs that constrain the evolution of these traits. Although life history theory has made enormous progress in explaining the diversity of life history strategies among species, it traditionally ignores the underlying proximate mechanisms. This novel book argues that many fundamental problems in life history evolution, including the nature of trade-offs, can only be fully resolved if we begin to integrate information on developmental, physiological, and genetic mechanisms into the classical life history framework. Each chapter is written by an established or up-and-coming leader in their respective field; they not only represent the state of the art but also offer fresh perspectives for future research. The text is divided into 7 sections that cover basic concepts (Part 1), the mechanisms that affect different parts of the life cycle (growth, development, and maturation; reproduction; and aging and somatic maintenance) (Parts 2-4), life history plasticity (Part 5), life history integration and trade-offs (Part 6), and concludes with a synthesis chapter written by a prominent leader in the field and an editorial postscript (Part 7).

Available in PDF, EPUB and Kindle. Book excerpt: The diversity of RNAs inside living cells is amazing. We have known of the more “classic” RNA species: mRNA, tRNA, rRNA, snRNA and snoRNA for some time now, but in a steady stream new types of molecules are being described as it is becoming clear that most of the genomic information of cells ends up in RNA. To deal with the enormous load of resulting RNA processing and degradation reactions, cells need adequate and efficient molecular machines. The RNA exosome is arising as a major facilitator to this effect. Structural and functional data gathered over the last decade have illustrated the biochemical importance of this multimeric complex and its many co-factors, revealing its enormous regulatory power. By gathering some of the most prominent researchers in the exosome field, it is the aim of this volume to introduce this fascinating protein complex as well as to give a timely and rich account of its many functions. The exosome was discovered more than a decade ago by Phil Mitchell and David Tollervey by its ability to trim the 3’end of yeast, S. cerevisiae, 5. 8S rRNA. In a historic account they laid out the events surrounding this identification and the subsequent birth of the research field. In the chapter by Kurt Januszyk and Christopher Lima the structural organization of eukaryotic exosomes and their evolutionary counterparts in bacteria and archaea are discussed in large part through presentation of structures.
