Download or read book Regulation of Stress Induced Gene Expression in Saccharomyces Cerevisiae written by Vasudha Bharatula and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Transcription initiation is complex process involving transcription factors(TF), co-activators, nucleosome remodelers and the pre-initiation complex (PIC);general transcription factors (GTF) and RNA polymerase II (RNAP2). The spatiotemporalorganization of these different proteins and their role in regulatingplasticity and selectivity of transcriptional reprogramming in various stressesremains unknown. I describe the role of Multicopy Suppressor of Snf1 mutation(Msn2); a stress responsive transcription factor, Mediator (coactivator) andnucleosome remodeling in fine-tuning gene expression in response to stress inyeast.Msn2 exhibits distinct patterns of nucleo-cytoplasmic oscillations indifferent stresses. I determined that Msn2 target genes exhibited fast or slowinduction kinetics in response to transient and persistent Msn2 nuclearoccupancy respectively. Chromatin immunoprecipitation studies revealed thatMsn2 binds promoters of common stress genes as well as condition specificgenes in nutrient and oxidative stresses, suggesting that TF dynamics could playa role in selective gene regulation in different stresses. Additionally, Msn2binding to ~30 oxidative genes was dependent on Yap1. However, deleting Msn2did not lead to a significant decrease in expression of oxidative stress responsegenes as did the absence of Yap1. These results suggest that indirectcooperativity between Msn2 and Yap1 could lead to selective promoter bindingbut the effects of such interactions on gene expression remain unclear.I studied the role of Mediator in native conditions, where its function has not been adequately addressed. Mediator occupies chromosomal interacting domains (CID), which mark boundaries between interacting genomic regions, suggesting that Mediator could play a significant role in higher-order genome organization along with functioning as a coactivator.Finally, I assessed the combined effect of Msn2, Mediator and nucleosome remodeling on gene expression upon nutrient deprivation. Both Msn2 and Mediator are selectively recruited to promoters of genes activated and repressed in nutrient stress. Genes activated by Msn2 exhibited rapid loss of nucleosomes, in an Msn2 dependent manner. In contrast, repression of genes was not accompanied by a significant gain in nucleosomes, suggesting additional mechanisms of repression could exist. The absence of Msn2, significantly decreased Mediator recruitment at promoters of target genes, indicating that Mediator- TF interactions are crucial for gene expression changes in stress. Interestingly, both RNAP2 and Mediator remained poised at promoters of repressed genes, possibly to re-initiate transcription once the stress has passed.These findings offer novel insights on how Msn2 regulates expression of specific genes depending on the environment by modulating its dynamics and genomic binding. The binding of Msn2 helps recruit Mediator and facilitate nucleosome loss at genes induced in stress. Whereas, repressed genes seems to possess Mediator and RNAP2 in an inactive form which could be the mechanism of repression and a way to activate these genes immediate after stress.

Download or read book Relevance of Translational Regulation on Plant Growth and Environmental Responses written by Alejandro Ferrando and published by Frontiers Media SA. This book was released on 2018-02-19 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants, as sessile organisms, are exposed to a large array of challenging external and internal alterations that may restrict plant growth. These limiting growth conditions activate plant signalling responses which eventually target the protein synthesis machinery to rapidly reprogram plant metabolism to adapt to the new situation. Thus, the control of mRNA translation is one key regulatory step of gene expression and it is an essential molecular mechanism used by plants to bring about impressive growth plasticity. Compared to the vast number of studies aimed to identify plant transcriptional changes upon hormonal or environmental cues, the subsequent steps of mRNA transport, stability, storage, and eventually translational regulation, have been less studied in plants. This lack of knowledge concerns not only the fate of protein-coding transcripts in plants, but also the biogenesis and maturation of rRNAs, tRNAs and the plant translation factors involved. In this eBook we have focused on how internal cues and external signals of either biotic or abiotic origin impact translation to adjust plant growth and development. We have collected altogether ten scientific contributions to extend the knowledge on plant post-transcriptional and translational events that regulate the production of proteins that execute the required cellular functions. We hope that this compilation of original research articles and reviews will provide the readers with a detailed update on the state of knowledge in this field, and also with additional motivation to improve plant growth adaptation to future environmental challenges.
Download or read book Quantitative Proteomics written by Claire E Eyers and published by Royal Society of Chemistry. This book was released on 2014 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a component of post-genome science, the field of proteomics has assumed great prominence in recent years. Whereas quantitative analyses focussed initially on relative quantification, a greater emphasis is now placed on absolute quantification and consideration of proteome dynamics. Coverage of the topic of quantitative proteomics requires consideration both of the analytical fundamentals of quantitative mass spectrometry and the specific demands of the problem being addressed. Quantitative Proteomics aims to outline the state of the art in mass spectrometry-based quantitative proteomics, describing recent advances and current limitations in the instrumentation used, together with the various methods employed for generating high quality data. Details on both strategies describing how stable isotope labelling can be applied and methods for performing quantitative analysis of proteins in a label-free manner are given. The utility of these strategies to understanding cellular protein dynamics are then exemplified with chapters looking at spatial proteomics, dynamics of protein function as determined by quantifying changes in protein post-translational modification and protein turnover. Finally, a key application of these techniques to biomarker discovery and validation is presented, together with the rapidly developing area of quantitative analysis of protein-based foodstuffs. This exemplary book is essential reading for analytical and biological mass spectrometrists working in proteomics research, as well as those undertaking either fundamental or clinical-based investigations with an interest in understanding protein dynamics and/or biomarker assessment.

Download or read book Industrial and Host Associated Stress Responses in Food Microbes Implications for Food Technology and Food Safety written by Lorena Ruiz and published by Frontiers Media SA. This book was released on 2017-10-19 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout the food processing chain and after ingestion by the host, food associated bacteria have to cope with a range of stress factors such as thermal and/or non-thermal inactivation treatments, refrigeration temperatures, freeze-drying, high osmolarity, acid pH in the stomach or presence of bile salts in the intestine, that threaten bacterial survival. The accompanying plethora of microbial response and adaptation phenomena elicited by these stresses has important implications for food technology and safety. Indeed, while resistance development of pathogenic and spoilage microorganisms may impose health risks for the consumer and impart great economic losses to food industries, reduced survival of probiotic bacteria may strongly compromise their claimed health benefit attributes. As a result, substantial research efforts have been devoted in the last decades to unravel the mechanisms underlying stress response and resistance development in food associated microorganisms in order to better predict and improve (i) the inactivation of foodborne pathogens and spoilage microorganisms on the one hand and (ii) the robustness and performance of beneficial microorganisms on the other. Moreover, the recent implementation of system-wide omics and (single-)cell biology approaches is greatly boosting our insights into the modes of action underlying microbial inactivation and survival. This Research Topic aims to provide an avenue for dissemination of recent advances within the field of microbial stress response and adaptation, with a particular focus not only on food spoilage and pathogenic microorganisms but also on beneficial microbes in foods.
