Abstract

ca. 200 words; this text will present the book in all promotional forms (e.g. flyers). Please describe the book in straightforward and consumer-friendly terms.[Estrogen receptors (ERs) are typical members of the superfamily of nuclear receptors that mainly function as ligand-inducible transcription factors that bind chromatin, as homodimers, at specific response elements. A tight reciprocal coupling between rapid ‘non-genomic’ and ‘genomic’ ER actions may also occur in many physiological processes. ERs have long been evaluated for their roles in controlling the expression of genes involved in vital cellular processes such as proliferation, apoptosis, and differentiation. Therefore, given the various and pleiotropic functions of ERs, the dysregulation of their pathways contributes to several diseases such as the hormone-dependent breast; endometrial and ovarian cancers; and neurodegenerative diseases, cardiovascular diseases, and osteoporosis. In this printed edition of the Special Issue, “Molecular Pathways of Estrogen Receptor Action”, promising results on understanding the mechanisms underlying ER-mediated effects in various pathophysiological processes are represented, covering different roles of ER pathways in the tumorigenesis, the resistance to endocrine therapy, the dynamics of 3D genome organization, and cross-talk with other signaling pathways. This Special Issue also provides insight into the emerging roles of estrogen-signaling pathways in lung cancer, the tumor microenvironment, and the immune system.]

Abstract

The ability of pathogens, such as parasites, bacteria, fungi and viruses to invade, persist and adapt in both invertebrate and vertebrate hosts is multifactorial and depends on both pathogen and host fitness. Communication between a pathogen and its host relies on a wide and dynamic array of molecular interactions. Through this constant communication most pathogens evolved to be relatively benign, whereas killing of its host by a pathogen represents a failure to adapt. Pathogens are lethal to their host when their interaction has not been long enough for adaptation. Evolution has selected conserved immune receptors that recognize signature patterns of pathogens as non-self elements and initiate host innate responses aimed at eradicating infection. Conversely, pathogens evolved mechanisms to evade immune recognition and subvert cytokine secretion in order to survive, replicate and cause disease. The cell signaling machinery is a critical component of the immune system that relays information from the receptors to the nucleus where transcription of key immune genes is activated. Host cells have developed signal transduction systems to maintain homeostasis with pathogens. Most cellular processes and cell signaling pathways are tightly regulated by protein phosphorylation in which protein kinases are key protagonists. Pathogens have developed multiple mechanisms to subvert important signal transduction pathways such as the mitogen activated protein kinase (MAPK) and the nuclear factor kB (NF-kB) pathways. Pathogens also secrete effectors that manipulate actin cytoskeleton and its regulators, hijack cell cycle machinery and alter vesicular trafficking. This research topic focuses on the cellular signaling mechanisms that are essential for host immunity and their subversion by pathogens.

Abstract

Undoubtedly, pain conditions the quality of life of millions of people worldwide suffering a wide range of diseases. Major research efforts are being made by the international scientific community to determine the mechanisms underlying nociception. Growing evidence points out a complex network including oxidative and nitrosative stress, inflammatory response and cation signaling. In this sense, transient receptor potential (TRP) channels have attracted researchers’ attention. Expression levels are very different in tissues and cells mediating a myriad of processes in our organism. At the neurological level, it has been observed that the expression levelsof four TRP channels (TRPA1, TRPM2, TRPV1, and TRPV4) are high in neurons related to nociception, including dorsal root ganglion and trigeminal ganglia neurons. For this reason, this research field promises to shed light on this intricated matrix linking oxidative stress, calcium signaling (via TRP channels), and inflammatory signals in different pain modalities, including neuropathic pain and chemotherapy-induced peripheral pain. In such a way, all this intense research activity will enable us to design individual and rational treatment strategies for pain relief, such as the use of molecular neurosurgery.

Abstract

A hallmark of inflammation is the accumulation of leukocytes, which can serve to remove pathogens and necrotic tissue, but may also damage healthy tissue and exacerbate the inflammatory response. Our understanding of leukocyte recruitment in inflammation was revolutionized in the late 1980s by the discovery of chemokines (chemotactic cytokines), a family of small, secreted proteins that induce migration of selective subsets of leukocytes. Shortly afterwards, chemokines were found to exert their functions through the now familiar chemokine receptors, members of the G protein-coupled receptor superfamily. As their physiological and pathological functions were elucidated, chemokine receptors have become popular targets for drug development in inflammatory diseases as well as cancer metastasis and HIV infection. Extensive research has revealed that the functions of chemokines and their receptors are regulated at numerous levels, including: genetic mutations/polymorphisms; control of expression levels; ligand internalization via functional or decoy receptors; intrinsic selectivity of chemokine-receptor binding; hetero- or homo-oligomerization of chemokines or of receptors; alternative signalling pathways; interaction of chemokines with glycosaminoglycans; post-translational modifications; and binding to pathogen-derived inhibitors. This Special Issue of IJMS focused on the natural and pharmacological mechanisms by which the activities of chemokines and their receptors can be regulated.

Abstract

Head formation requires the well-orchestrated and harmonised development of various tissues and organs within the craniofacial complex. A big variety of signaling pathways are involved in this process by controlling cell proliferation, migration, differentiation, tissue morphogenesis, homeostasis and regeneration. Deregulation and malfunction of these signaling molecules may lead to mild or severe craniofacial pathologies. This eBook is a collection of articles dealing with a variety of important signals involved in the control of developmental and pathological events of craniofacial organs and tissues. These recent advances show the importance of signaling pathways in craniofacial physiology and pathology and generate important new knowledge aiming the development of new pharmaceutical products that mimic and/or block the actions of specific molecules.

Abstract

The notion that androgens and androgen receptor (AR) signaling are the hallmarks of prostate cancer oncogenesis and disease progression is generally well accepted. What is more poorly understood is the role of AR signaling in other human malignancies. This Special Issue of Cancers initially reviews the role of AR in advanced prostate cancer, and then explores the potential importance of AR signaling in other epithelial malignancies. The first few articles focus on the use of novel AR-targeting therapies in castration-resistant prostate cancer and the mechanisms of resistance to novel antiandrogens, and they also outline the interaction between AR and other cellular pathways, including PI3 kinase signaling, transcriptional regulation, angiogenesis, stromal factors, Wnt signaling, and epigenetic regulation in prostate cancer. The next several articles review the possible role of androgens and AR signaling in breast cancer, bladder cancer, salivary gland cancer, and hepatocellular carcinoma, as well as the potential treatment implications of using antiandrogen therapies in these non-prostatic malignancies.

Abstract

NK cells are lymphocytes of the innate immune system that share some features with adaptive immune cells like T cells. They are well known for their importance to control viral infections and tumor development, but also intracellular bacterial and parasitic infections. A balance between negative and positive signals transmitted via germ line-encoded inhibitory and activating receptors controls the function of NK cells. Activated NK cells respond by killing the infected or tumor cells without prior sensitization, and by producing cytokines and chemokines. It has been shown that NK cells cross-talk with other immune cells, such as dendritic cells and macrophages, can shape T cell and B cell immune responses through direct interactions as well as by virtue of their cytokine/chemokine production. NK cells can also regulate immune responses by killing other immune cells, including activated T cells, or by producing anti-inflammatory cytokines upon excessive inflammation. However, NK cells are not friends in all situations. Indeed, it has been shown in LCMV-infected murine models that, depending on the viral inoculation load, NK cells may either help fight infection or can promote chronic infection. Moreover in cancer models, it has been shown that NK cells can kill anti-tumoral T cells. Recent studies of NK cells in patients with cancer support the notion of detrimental roles of NK cells. Furthermore, studies implicate NK cells in contributing to both graft rejection and tolerance to an allograft. In some autoimmune diseases, like rheumatoid arthritis, NK cells may promote disease pathogenesis. The scope of this Research Topic is to present and discuss knowledge on the role of NK cells in various diseases settings: viral infections as well as other infections, cancer, transplantation, and autoimmunity. The aim is to discuss how NK cells respond during disease and specifically when, why and how NK cells can be harmful and if they exert different functions (production of specific cytokines, inhibition of other immune cells through other mechanisms beside cytotoxicity) in these situations. Which are the NK cell subsets that play beneficial or deleterious roles in these diseases? Are there different phenotypes associated with protective NK cells (e.g. antiviral, antitumoral) and NK cells involved in disease pathogenesis? How are these diverse NK cells activated and do they function primarily through direct cytotoxicity, ADCC or cytokine and chemokine production? What are the signals or interactions that can change and shape the NK cell response shifting them from protective to harmful? We thank the authors that submitted reviews and original research manuscripts that help to better understand these questions, with the aim that this will help the scientific community to determine what could be the main future research directions to better understand the role of NK cells in disease protection or development.

Abstract

There has been an observed decrease in the global mortality from cancer, mostly atributable to improved, particularly early, detection and prevention. For many carcinomas and leukaemias in adults, once the disease has reached a certain stage there are no therapies that are able to erradicate the cancer cells and cure patients. There has been progress in the treatment of acute myeloid leukaemia (AML) and remissions are achievable; however, the presence of chemoresistent blast cells leads to most patients relapsing, and relapse is difficult to treat and thus patients die due to their disease. Targeting these resistent cells and the leukaemia stem cells, which sustain the leukaemia, is crucial for an effective therapy for AML. Moreover, an increasing number of diverse mutations have been described in AML cells that disrupt the ability of these cells to undergo differentiation. The use of pro-differentiating agents to drive the blast cells to mature, and subsequently undergo apoptosis, provides another approach to therapy. Differentiation therapy, using all-trans retinoic acid (ATRA), an inducer of granulocyte differentiation, has been highly successful in the case of acute promyeloicytic leukaemia, a sub-type of AML, turning this disease into a curable malignancy.

Abstract

Although mortality rates have declined in recent years, the majority of cancers are still difficult to treat and the medical need for better cancer treatment is evident. The current anticancer armamentarium includes many active agents that are applied across tumor types. However, most of these broadly-active anticancer drugs have a small therapeutic index and barely discriminate between malignant and normal cells. In recent years the focus has shifted to the development of rationally designed, molecularly-targeted therapy for the treatment of a specific cancer, therefore offering the promise of greater specificity coupled with reduced systemic toxicity. NF-kB transcription factor family as emerged as such a promising target for cancer therapy. This Special Issue will explore the routes from NF-kB basic research, cancer research and oncogenomics into the development of NF-kB-based cancer therapeutics and biomarkers.We invite research and review papers in any area of the NF-kB field that are related, but not limited to, fundamental understanding of NF-kB signaling pathways, gene expression profiling, epigenetic regulation, diagnostic, prognostic and pharmacogenomic biomarkers, molecular targets driving the progression of human cancers, cancer drug development on these targets, clinical trial with new agents, and validation in animal models.We hope that this Special Issue reflects the exciting era that we are living in with respect to the field of NF-kB and its applications in cancer research.
