This contributed volume reviews the recent progress in our understanding of membrane transport in yeast including both Saccharomyces cerevisiae and non-conventional yeasts. The articles provide a summary of the key transport processes and put these in a systems biology context of cellular regulation, signal reception and homeostasis. After a general introduction, readers will find review articles covering the mechanisms and regulation of transport for various substrates ranging from diverse nutrients to cations, water and protons. These articles are complemented by a chapter on extremophilic yeast, a chapter on the mathematical modelling of ion transport and two chapters on the role of trans...
This book is a valuable reference that discusses green technologies, like enzyme technologies, to meet the ever-growing demand of nutraceuticals and functional foods. Microorganisms like bacteria (lactic acid bacteria, Bacillus species), yeasts, and filamentous fungi have been exploited for food preparations globally. Microbial Enzymes in Production of Functional Foods and Nutraceuticals discusses how to use them commercially. Chapters include enzyme sources, processing, and the health benefits of microbial enzymes. Other interesting Chapters include the application of metagenomics and the molecular engineering of enzymes. This book is useful for students, academicians, and industry experts in food science and applied microbiology.
Cancer is characterized by heterogeneous cells with capacity for self renewal, and selective pressures in the microenvironment which constantly change the cell population. This "descent with modification" is consistent with Darwin's definition of evolution, and accordingly, cancer progression can be captured from an evolutionary angle. However, there is also a clear difference between cancer progression and biological evolution. First, contrary to the evolution of complex organisms, cancer originates from cells of multicellular organisms that escape their constraints and behave like unicellular organisms. Therefore, from the beginning, cancer cells have complex genomes that contain abundant genetic materials which they can use to change their phenotype by dynamic rearrangements and modifications. Secondly, epigenetic effects promote cancer evolution in contrast to the evolution of life. Some tumors develop with minimal genetic alterations, and cell plasticity contributes to both initiation and progression in various tumors. However, an evolutionary theory that encompasses these characteristics of cancer remains to be developed.
The nervous system is the product of biological evolution and is shaped by the interplay between extrinsic factors determining the ecology of animals, and by intrinsic processes that dictate the developmental rules that give rise to adult functional structures. This special topic is oriented to develop an integrative view from behavior and ecology to neurodevelopmental processes. We address questions such as how do sensory systems evolve according to ecological conditions? How do neural networks organize to generate adaptive behavior? How does cognition and brain connectivity evolve? What are the developmental mechanisms that give rise to functional adaptation? Accordingly, the book is divid...
Foreword from the Field Chief Editor, Giuseppe Giaccone Once again Frontiers in Oncology has started the year on a positive note, breaking previous records for submissions and publications, as well as the number of Research Topic article collections posted. The journal continues to grow in size, adding an 18th section focusing on Cancer Metabolism, led by Michael Lisanti and Ubaldo Martinez-Outschoorn, and has brought on a total of five new Chief Editors. Here, introducing Frontiers in Oncology: Quarterly Highlights, we feature a collection of carefully selected articles published during the first quarter of 2019 across the different sections. With a record number of papers to choose from, t...
An introduction to the emerging field of cancer physics, integrating cancer biology with approaches from theoretical and applied physics.
This topic has been realized, and is in collaboration with Dr. Constanze Pentzold, Post Doctoral Researcher at the Institute of Human Genetics, University Hospital Jena.
