This book was released on 2012 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: The patterns and mechanisms by which eukaryotic cells regulate the expression of their genetic information are highly complex and intricate. The transmittance of this information from nuclear repository to cytoplasmic translation contains within it several steps, including the selective removal and concomitant joining of pieces of information in a process called alternative splicing. The projects detailed within this document describe the regulation of alternative splicing through the interaction of specific proteins with specific pre-mRNA transcripts. The Rio lab has studied PSI, a protein involved in the regulation of the P element transposase transcript, for many years. It has since been shown to regulate the splicing of hundreds of other transcripts. The experiments described here look at the organization of PSI and other proteins on the P element transcript by site-specific labeling of the transcript using radioactive 32P. We also investigate two phosphorylation events of PSI, identifying the kinases responsible and demonstrate that these events may change the protein-protein interaction partners of PSI. It has become increasingly apparent that alternative splicing may not only be regulated by protein/RNA interactions, but also by RNA/RNA interactions. To probe this, we designed experiments to test if some well-known small RNA-associated proteins are regulating alternative splicing. Using splice junction microarrays, we determined that Argonaute-2 (Ago-2) regulated the splicing of over 100 splice junctions, and further experiments using ChIP-seq and mRNA-seq of Ago-2 mutants revealed that Ago-2 also has a role in transcriptional repression, possibly through being incorporating in complexes composed of polycomb-group genes. We also used CLIP-seq to determine the RNA binding profile and preferences of Ago-2 in Drosophila tissue culture cells. Finally, we characterized the functions of a Drosophila specific splicing factor called LS2. LS2 is orthologous to the highly conserved splicing factor dU2AF50, but its origin through retroduplication and subsequent divergence to acquire distinct sequence specificity, expression pattern, and function show it to be an interesting case in the evolution of alternative splicing regulation. This may be a mechanism that underlies the existence of some members of the large families of splicing factors, including hnRNP proteins and SR proteins. That is, by duplicating functional copies of genes, cellular systems create new proteins to tinker with and acquire new functions while keeping the former functionality and stability of the parent protein. While these projects are essentially independent of each other, they all fall under the umbrella of protein regulation of RNA metabolism and hopefully contribute to a more complete understanding of the regulation of gene expression.

Download or read book Grappling with the Multifaceted World of the DNA Damage Response written by Antonio Porro and published by Frontiers Media SA. This book was released on 2017-01-10 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: DNA damage is a major threat to genomic integrity and cell survival. It can arise both spontaneously and in response to exogenous agents. DNA damage can attack most parts of the DNA structure, ranging from minor and major chemical modifications, to single-strand breaks (SSBs) and gaps, to full double-strand breaks (DSBs). If DNA injuries are mis-repaired or unrepaired, they may ultimately result in mutations or wider-scale genome aberrations that threaten cell homeostasis. Consequently, the cells elicit an elaborate signalling network, known as DNA damage response (DDR), to detect and repair these cytotoxic lesions. This Research Topic was aimed at comprehensive investigations of basic and novel mechanisms that underlie the DNA damage response in eukaryotes.

Available in PDF, EPUB and Kindle. Book excerpt: While there has been an increasing number of books on various aspects of epigenetics, there has been a gap over the years in books that provide a comprehensive understanding of the fundamentals of chromatin. Chromatin is the combination of DNA and proteins that make up the genetic material of chromosomes. Its primary function is to package DNA to fit into the cell, to strengthen the DNA to prevent damage, to allow mitosis and meiosis, and to control the expression of genes and DNA replication. The audience for this book is mainly newly established scientists and graduate students. Rather than going into the more specific areas of recent research on chromatin the chapters in this book give a strong, updated groundwork about the topic. Some the fundamentals that this book will cover include the structure of chromatin and biochemistry and the enzyme complexes that manage it.

Download or read book Genetics and Genomics of the Brassicaceae written by Renate Schmidt and published by Springer Science & Business Media. This book was released on 2010-12-03 with total page 675 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Genetics and Genomics of the Brassicaceae provides a review of this important family (commonly termed the mustard family, or Cruciferae). The family contains several cultivated species, including radish, rocket, watercress, wasabi and horseradish, in addition to the vegetable and oil crops of the Brassica genus. There are numerous further species with great potential for exploitation in 21st century agriculture, particularly as sources of bioactive chemicals. These opportunities are reviewed, in the context of the Brassicaceae in agriculture. More detailed descriptions are provided of the genetics of the cultivated Brassica crops, including both the species producing most of the brassica vegetable crops (B. rapa and B. oleracea) and the principal species producing oilseed crops (B. napus and B. juncea). The Brassicaceae also include important “model” plant species. Most prominent is Arabidopsis thaliana, the first plant species to have its genome sequenced. Natural genetic variation is reviewed for A. thaliana, as are the genetics of the closely related A. lyrata and of the genus Capsella. Self incompatibility is widespread in the Brassicaceae, and this subject is reviewed. Interest arising from both the commercial value of crop species of the Brassicaceae and the importance of Arabidopsis thaliana as a model species, has led to the development of numerous resources to support research. These are reviewed, including germplasm and genomic library resources, and resources for reverse genetics, metabolomics, bioinformatics and transformation. Molecular studies of the genomes of species of the Brassicaceae revealed extensive genome duplication, indicative of multiple polyploidy events during evolution. In some species, such as Brassica napus, there is evidence of multiple rounds of polyploidy during its relatively recent evolution, thus the Brassicaceae represent an excellent model system for the study of the impacts of polyploidy and the subsequent process of diploidisation, whereby the genome stabilises. Sequence-level characterization of the genomes of Arabidopsis thaliana and Brassica rapa are presented, along with summaries of comparative studies conducted at both linkage map and sequence level, and analysis of the structural and functional evolution of resynthesised polyploids, along with a description of the phylogeny and karyotype evolution of the Brassicaceae. Finally, some perspectives of the editors are presented. These focus upon the Brassicaceae species as models for studying genome evolution following polyploidy, the impact of advances in genome sequencing technology, prospects for future transcriptome analysis and upcoming model systems.

This book was released on 2013-05-22 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume describes the latest findings on transcriptional and translational regulation of stem cells. Both transcriptional activators and repressors have been shown to be crucial for the maintenance of the stem cell state. A key element of stem cell maintenance is repression of differentiation factors or developmental genes – achieved transcriptionally, epigenetically by the Polycomb complex, and post-transcriptionally by RNA-binding proteins and microRNAs. This volume takes two approaches to this topic – (1) illustrating the general principles outlined above through a series of different stem cell examples – embryonic, iPS and adult stem cells, and (2) describing several molecular families that have been shown to have roles in regulation of multiple stem cell populations.

Available in PDF, EPUB and Kindle. Book excerpt: Plants, unlike animals, are sessile. This demands that adverse changes in their environment are quickly recognized, distinguished and responded to with suitable reactions. Drought, heat, cold and salinity are among the major abiotic stresses that adversely affect plant growth and productivity. In general, abiotic stress often causes a series of morphological, physiological, biochemical and molecular changes that unfavorably affect plant growth, development and productivity. Drought, salinity, extreme temperatures (cold and heat) and oxidative stress are often interrelated; these conditions singularly or in combination induce cellular damage. To cope with abiotic stresses, of paramount significance is to understand plant responses to abiotic stresses that disturb the homeostatic equilibrium at cellular and molecular level in order to identify a common mechanism for multiple stress tolerance. This multi authored edited compilation attempts to put forth an all-inclusive biochemical and molecular picture in a systems approach wherein mechanism and adaptation aspects of abiotic stress are dealt with. The chief objective of the book hence is to deliver state of the art information for comprehending the effects of abiotic stress in plants at the cellular level.
