Book Description
SUMO modification is involved in several cellular processes such as signal transduction, cell division, and regulation of protein subcellular localization, specifically including Ras signaling and protein nuclear import/export. Previous studies have demonstrated that 14-3-3[zeta], which is thought to have functions in both the nucleus and cytoplasm, is a SUMOylated protein and is required for Ras signaling. I have therefore sought to determine whether or not the SUMOylation of 14-3-3[zeta] promotes or inhibits its localization to the nucleus. Subcellular fractionation experiments fail to reveal a detectable change in the overall ratio of nuclear to cytoplasmic 14-3-3[zeta] upon knockdown of SUMO by RNAi in cultured Drosophila cells. However, immunofluorescence studies suggest that nuclear localization of this protein may increase in a subset of the SUMO knockdown cells.

Book Description
The PI3Ks control many key functions in immune cells. PI3Ks phosphorylate PtdIns(4,5)P2 to yield PtdIns(3,4,5)P3. Initially, PI3K inhibitors such as Wortmannin, LY294002 and Rapamycin were used to establish a central role for Pi3K pathway in immune cells. Considerable progress in understanding the role of this pathway in cells of the immune system has been made in recent years, starting with analysis of various PI3K and Pten knockout mice and subsequently mTOR and Foxo knockout mice. Together, these experiments have revealed how PI3Ks control B cell and T cell development, T helper cell differentiation, regulatory T cell development and function, B cell and T cell trafficking, immunoglobulin class switching and much, much more. The PI3Kd inhibitor idelalisib has recently been approved for the treatment of B cell lymphoma. Clinical trials of other PI3K inhibitors in autoimmune and inflammatory diseases are also in progress. This is an opportune time to consider a Research Topic considering when what we have learned about the PI3K signalling module in lymphocyte biology and how this is making an impact on clinical immunology and haematology.

Book Description
This volume takes a closer look how the cell organelles Golgi apparatus (also known as the Golgi complex or Golgi body), and centriole are structurally and functionally intertwined. Initially, it was believed that the role of Golgi complex is limited to the packaging and preparation for secretion of various cellular proteins, while the centriole participates in cell division and cilia formation. However, since their discovery nearly 200 years ago, it became clear that these two organelles are interacting, and that their functions are much more complex and far reaching than previously thought. Recent findings indicate that the Golgi–Centriole relationship may be important for directional protein transport, cell polarization and cell cycle progression. Current studies indicate that Golgi and centriole also participate in development and act as cellular and immunological sensors, and that their abnormalities lead to cell and developmental abnormalities, Alzheimer, cancer, various lipid disorders and neurological and immunological diseases in humans. This volume combines the latest information on the structure, molecular composition, and roles of Golgi and centriole in various cellular functions and diseases. The better understanding of the Golgi–centriole interactions may lead to the development of novel therapies for the treatment of various diseases, including cancer.

Book Description
Squamous epithelia form the lining surface of tissues in contact with the environment: the skin, oral mucosa, esophagus and respiratory tract, the genital tract, and several other specialized tissues. These tissues are at highest risk for exposure to environmental carcinogens such as UV, tobacco smoke and infectious agents. Cancers that form in squamous epithelia are among the most common human solid tumors and have high morbidity and mortality. These cancers include squamous cell carcinoma of the skin, oral cancer, head and neck and esophageal cancer, certain lung cancers and cervical cancer. We propose to organize the book so that the early chapters will focus on individual pathways and more specific mechanisms in both normal function and cancer, while the later chapters will be more integrative and include overviews of biomarkers and therapeutic development. This should increase interest for clinically oriented researchers. All authors will be encouraged to provide a balanced review in addition to highlighting their own work.

Book Description
Epigenetic Gene Expression and Regulation reviews current knowledge on the heritable molecular mechanisms that regulate gene expression, contribute to disease susceptibility, and point to potential treatment in future therapies. The book shows how these heritable mechanisms allow individual cells to establish stable and unique patterns of gene expression that can be passed through cell divisions without DNA mutations, thereby establishing how different heritable patterns of gene regulation control cell differentiation and organogenesis, resulting in a distinct human organism with a variety of differing cellular functions and tissues. The work begins with basic biology, encompasses methods, cellular and tissue organization, topical issues in epigenetic evolution and environmental epigenesis, and lastly clinical disease discovery and treatment. Each highly illustrated chapter is organized to briefly summarize current research, provide appropriate pedagogical guidance, pertinent methods, relevant model organisms, and clinical examples. - Reviews current knowledge on the heritable molecular mechanisms that regulate gene expression, contribute to disease susceptibility, and point to potential treatment in future therapies - Helps readers understand how epigenetic marks are targeted, and to what extent transgenerational epigenetic changes are instilled and possibly passed onto offspring - Chapters are replete with clinical examples to empower the basic biology with translational significance - Offers more than 100 illustrations to distill key concepts and decipher complex science

Book Description
This volume serves as a proteomics reference manual, describing experimental design and execution. The book also shows a large number of examples as to what can be achieved using proteomics techniques. As a relatively young area of scientific research, the breadth and depth of the current state of the art in proteomics might not be obvious to all potential users. There are various books and review articles that cover certain aspects of proteomics but they often lack technical details. Subject specific literature also lacks the broad overviews that are needed to design an experiment in which all steps are compatible and coherent. The objective of this book was to create a proteomics manual to provide scientists who are not experts in the field with an overview of: 1. The types of samples can be analyzed by mass spectrometry for proteomics analysis. 2. Ways to convert biological or ecological samples to analytes ready for mass spectral analysis. 3. Ways to reduce the complexity of the proteome to achieve better coverage of the constituent proteins. 4. How various mass spectrometers work and different ways they can be used for proteomics analysis 5. The various platforms that are available for proteomics data analysis 6. The various applications of proteomics technologies in biological and medical sciences This book should appeal to anyone with an interest in proteomics technologies, proteomics related bioinformatics and proteomics data generation and interpretation. With the broad setup and chapters written by experts in the field, there is information that is valuable for students as well as for researchers who are looking for a hands on introduction into the strengths, weaknesses and opportunities of proteomics.
