Physiologic Regulation of FGF-23

Study record managers: refer to the Data Element Definitions if submitting registration or results information. This study will explore the regulation of fibroblast growth factor FGF It is a hormone recently identified as a regulator of the blood levels of phosphorus and vitamin D, both of which are essential for overall health and especially important for bone health. The parathyroid hormone PTH regulates phosphorus and calcium, but people with hypoparathyroidism or pseudohypoparathyroidism do not have sufficient PTH action. There are genetic diseases that influence FGF, causing abnormal metabolism of phosphorus and vitamin D, thus affecting the bones. Also, there are rare tumors that may cause overproduction of FGF causing debilitating bone disease. Patients ages 18 and older who have low PTH levels, or are resistant to PTH action, and take calcitriol and calcium supplements, who are not pregnant, and who do not have kidney disorders may be eligible for this study.

Fibroblast growth factors FGFs mediate many cell-cell signaling events during early development. Comparison of our results with previously reported FGFR expression patterns reveals that FGFR-1 expression is highly conserved among vertebrate embryos, and FGFR-2 expression shows many features that are conserved and some that are divergent. In contrast, the expression pattern of FGFR-4 is highly divergent among vertebrate embryos.

Classification of FGFs & Receptors

Fibroblast growth factor 2 FGF2 is one of the most studied growth factors to date. Most attention has been dedicated to the smallest, 18kDa FGF2 variant that is released by cells and acts through activation of cell-surface FGF-receptor tyrosine kinases. In this review, we summarize the current knowledge about the biology of HMW FGF2, its role in disease and areas for future investigation.

FGF2 is a growth factor that exists in several isoforms differing in their N-terminal extensions, subcellular distribution and function. This review will focus specifically on nuclear HMW FGF2 signalling, its molecular mechanisms and its physiological and pathological function. The longest UTR is used by primary cells, in contrast to short UTRs preferred by transformed cells in vitro , allowing for precise post-transcriptional regulation of FGF2 production in primary cells in contrast to transformed cells that express FGF2 in a constitutive manner, perhaps contributing to their transformed phenotype [ 3 , 4 ].

Background: Meningioma and glioma are common central nervous system tumors. Hypoxic tumor cells secrete angiogenic cytokines, such as vascular.

The fibroblast growth factor FGF family is one of the largest growth factor families, consisting of 18 intrinsic tissue regulatory polypeptides that share similarities in structure and amino acid sequence. The FGFs are broadly expressed, regulating cell proliferation, differentiation, survival, and The FGFs are broadly expressed, regulating cell proliferation, differentiation, survival, and function. Binding of the FGF to the FGFR-HS complex changes its conformation, leading to receptor autophosphorylation, as well as phosphorylation of downstream signaling molecules, thus, conveying the signals to downstream effectors.

As an intrinsic cell signaling axis, the FGF and FGFR are expressed almost ubiquitously in all tissues and stages, functioning either in autocrine, paracrine, or endocrine mechanisms. These intrinsic FGF signaling axes play important roles in embryonic development, adult tissue regeneration, homeostasis and function. Redundant FGF and FGFR expression is common in multiple tissues and organs to warrant signaling conveyance, with a loss of FGF signaling having been reported as the culprit for developmental disorders and diseases.

On the other hand, ectopic FGF signaling is pathological and has been found to underlie various diseases, ranging from birth defects and metabolic disorders, to cancer and cardiovascular disease. However, how FGF elicits cell type-specific pathological signals is poorly understood, although it is suspected that simply the long duration and high intensity of the signals play a causative role.

Fibroblast Growth Factor 21 (FGF-21, UNQ3115/PRO10196)

SUMMARY: This workshop is being held in recognition of the growing body of work on the use of fragile geologic features FGFs to evaluate probabilistic seismic hazard PSH models, and the emergence of different methods of application and evaluation. We will bring together scientists possessing experience in studies of FGFs, and scientists not currently involved in FGF work but possessing relevant expertise. The following examples come to mind: geology and surficial processes that lead to the formation and identification of FGFs; alternative methods for fragility and age estimation; statistical methods of PSH model evaluation; and experience with the setting of guidelines criteria.

We seek a clear definition of the state of the art of FGF-PSH model evaluation, and identification of the work and resources needed in order to achieve defensible evaluation methods for industry application. Presentation slides may be downloaded by clicking the links following the title.

Rasmussen, B. Lindblom, M. Angiogenesis is an important but poorly understood process of the cycling endometrium. Endometrial angiogenesis is believed to be regulated by angiogenic growth factors under the influence of ovarian steroids. Their expression was examined by immunohistochemistry in endometrial biopsies obtained from 16 healthy women with proven fertility. Western blot analysis showed that the primary antibodies used were specific for their epitopes.

No correlation was seen between receptor expression and stromal blood vessel density. Ovarian steroids are the prime modulators of the cyclic endometrial changes and they do this by interacting with local growth factors to regulate growth and differentiation of the endometrium Giudice, Following the onset of menstrual bleeding, the upper functional layer of the endometrium is shed, and at about this time endometrial regeneration commences.

The growth of the endometrium includes the growth of glands, stroma and vessels. Bleeding control and fertility depend on correct regeneration Cameron et al. Angiogenesis is defined as the formation of new capillary blood vessels from existent micro-vessels by sprouting, i. Other mechanisms by which angiogenesis occurs include intussusception of endothelial cells and vessel elongation Rogers et al.

Angiogenesis and blood vessel function depend on the interaction between endothelial cells, their basal membrane and stromal tissues surrounding capillary vessels Battegay, ; Risau,

High molecular weight FGF2: the biology of a nuclear growth factor

Although decades of studies have produced a generalized model for tetrapod limb development, urodeles deviate from anurans and amniotes in at least two key respects: their limbs exhibit preaxial skeletal differentiation and do not develop an apical ectodermal ridge AER. Here, we investigated how Sonic hedgehog Shh and Fibroblast growth factor Fgf signaling regulate limb development in the axolotl. We found that Shh -expressing cells contributed to the most posterior digit, and that inhibiting Shh-signaling inhibited Fgf8 expression, anteroposterior patterning, and distal cell proliferation.

We found that amniote and anuran AER-specific Fgfs and their cognate receptors were expressed entirely in the mesenchyme. Broad inhibition of Fgf-signaling demonstrated that this pathway regulates cell proliferation across all three limb axes, in contrast to anurans and amniotes where Fgf-signaling regulates cell survival and proximodistal patterning.

The protein encoded by this gene is a member of the fibroblast growth factor FGF family. FGF family members bind heparin and possess broad mitogenic and angiogenic activities. This protein has been implicated in diverse biological processes, such as limb and nervous system development, wound healing, and tumor growth. The CUG-initiated isoforms are localized in the nucleus and are responsible for the intracrine effect, whereas, the AUG-initiated form is mostly cytosolic and is responsible for the paracrine and autocrine effects of this FGF.

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.
