Abstract

The fibroblast growth factors (FGFs) represent one of the relatively few families of extracellular signalling peptides that have been shown in recent decades to be key regulators of metazoan development. FGFs are required for multiple processes in both protostome and deuterostome groups. Given the wide range of regulatory roles attributed to the FGFs, it is perhaps not surprising that misregulation of this signalling pathway has been implicated in a number of human disease conditions. The focus of the present review is to look at the fundamental components of the FGF pathway and illustrate how this highly conserved regulatory cassette has been deployed to regulate multiple, diverse processes during vertebrate development. This review will explore examples from several vertebrate model organisms and include discussions of the role of FGF signalling in regulating the establishment of the mesoderm, neural patterning, morphogenesis, myogenesis, limb development, and the establishment of right-left asymmetry.

Abstract

Fibroblast growth factors (FGFs) have been recognized primarily as autocrine/paracrine factors that regulate embryonic development and organogenesis. However, recent studies have revealed that some FGFs function as endocrine factors and regulate various metabolic processes in adulthood. Such FGFs, collectively called endocrine FGFs, are comprised of three members (FGF15/19, FGF21, and FGF23: FGF15 is the mouse ortholog of human FGF19). These endocrine FGFs share a common structural feature that enables the endocrine mode of action at the expense of the affinity to FGF receptors. To restore the affinity to FGF receptors in their target organs, the endocrine FGFs have designated the Klotho family of transmembrane proteins as obligate co-receptors. By expressing Klothos in a tissue-specific manner, this unique co-receptor system also enables the endocrine FGFs to specify their target organs among many tissues that express FGF receptors.

Abstract

The number of males diagnosed with prostate cancer (PCa) is increasing all over the world. Most patients with early-stage PCa can be treated with appropriate therapy, such as radical prostatectomy or irradiation. On the other hand, androgen deprivation therapy (ADT) is the standard systemic therapy given to patients with advanced PCa. ADT induces temporary remission, but the majority of patients (approximately 60%) eventually progress to castration-resistant prostate cancer (CRPC), which is associated with a high mortality rate. Generally, well-differentiated PCa cells are androgen dependent, i.e., androgen receptor (AR) signalling regulates cell cycle and differentiation. The loss of AR signalling after ADT triggers androgen-independent outgrowth, generating poorly differentiated, uncontrollable PCa cells. Once PCa cells lose their sensitivity to ADT, effective therapies are limited. In the last few years, however, several new options for the treatment of CRPC have been approved, e.g., the CYP17 inhibitor, the AR antagonist, and the taxane. Despite this progress in the development of new drugs, there is a high medical need for optimizing the sequence and combination of approved drugs. Thus, the identification of predictive biomarkers may help in the context of personalized medicine to guide treatment decisions, improve clinical outcomes, and prevent unnecessary side effects. In this Special Issue Book, we focused on the cytobiology of human PCa cells and its clinical applications to develop a major step towards personalized medicine matched to the individual needs of patients with early-stage and advanced PCa and CRPC. We hope that this Special Issue Book attracts the attention of readers with expertise and interest in the cytobiology of PCa cells.

Abstract

Fibroblast growth factor (FGF) signal transmission has an essential function in embryonic development and tissue repair, and is dysregulated in the vast majority of malignancies studied. The FGF signaling in the tumor cells is usually increased by autocrine and paracrine mechanisms and gives them a high growth potential, resistance to apoptosis, neoangiogenesis and metastasis, all essential parameters relevant for tumor progression. This makes FGFs, and their tyrosine kinase receptors FGFRs, valuable targets for therapeutic interventions. This book is a collection of 15 recent articles—both original work and reviews—that summarize the current research state effectively. The content covers FGF signaling aspects in gastric, skin, liver, esophageal cancer, melanoma, mesothelioma and glioblastoma, including one article that addresses the role of FGF in the tumor-microenvironment cross-talk. Several reports describe the development of compounds targeting FGFRs, their structure and interaction with the receptor molecules, and their effectivity in preclinical and clinical testing. In summary, the papers demonstrate the complexity of the topic, with various FGF ligands and receptors involved and the need for further research. They also present results that fuel hope that targeting cancer with dysfunctional FGF signaling can become a realistic treatment option.

Abstract

The mammalian brain has a high degree of plasticity, with dentate granule cell neurogenesis(1) and glial(2,3) proliferation stimulated by an enriched environment combining both complex inanimate and social stimulation. Moreover, rodents exposed to an enriched environment both before and after a cerebral insult show improved cognitive performance(1,4). One of the most robust associations of environmental enrichment is improved learning and memory in the Morris water maze, a spatial task that mainly involves the hippocampus(5). Furthermore, clinical evidence showing an association between higher educational attainment and reduced risk of Alzheimer(6) and Parkinson-related dementia(7) indicates that a stimulating environment has positive effects on cerebral health that may provide some resilience to cerebral insults. Here we show that in addition to its effects on neurogenesis, an enriched environment reduces spontaneous apoptotic cell death in the rat hippocampus by 45%. Moreover, these environmental conditions protect against kainate-induced seizures and excitotoxic injury. The enriched environment induces expression of glial-derived neurotrophic factor and brain-derived neurotrophic factor and increases phosphorylation of the transcription factor cyclic-AMP response element binding protein, indicating that the; influence of the environment on spontaneous apoptosis and cerebral resistance to insults may be mediated through transcription factor activation and induction of growth factor expression

Abstract

The regenerative and immunomodulatory properties of mesenchymal stem cells (MSCs) have made these cells the focus of multiple pre-clinical studies and clinical trials. While the results from these clinical studies have established that MSCs are safe, the efficacy of these cells is not as well-established. In this regard, there have been increased efforts towards generating potentiated/activated MSCs with enhanced therapeutic efficacy. Research on the mechanisms for enhancing MSC potency and efficacy is an area of active study with great potential for translation into clinical settings. The purpose of this book is to bring together recent research from a broad range of topics relating to potentiation strategies for enhancing MSC therapeutic efficacy, including growth factor pre-conditioning, hypoxia, and 3D culture. The research compiled in this book increases the basic understanding of MSC culture techniques and describes some MSC preparations for potential novel therapeutic applications.

Abstract

In this Special Issue of Genes entitled “Genetic Conditions Affecting the Skeleton: Congenital, Idiopathic Scoliosis and Arthrogryposis”, evidence is presented that suggests that congenital, idiopathic scoliosis, and arthrogryposis share similar overlapping, but also distinct, etiopathogenic mechanisms, including connective tissue and neuromuscular mechanisms. Congenital scoliosis (CS) is defined by the presence of an abnormal spinal curvature, due to an underlying vertebral bony malformation (VM). Idiopathic scoliosis (IS) is defined by the presence of an abnormal structural spinal curvature of ≥10 degrees in the sagittal plane, in the absence of an underlying VM. Arthrogryposis is defined by the presence of congenital contractures in two or more joints of the appendicular skeleton. All three conditions have complex genetic causes. This Special Issue highlights the complex nature of these conditions and current concepts in our approach to better understand their genetics.
