Fog2 Is Critical for Cardiac Function and Maintenance of Coronary Vasculature in the Adult Mouse Heart
Fog2 is critical for cardiac function and maintenance of coronary vasculature in the adult mouse heart Bin Zhou, … , Sergei G. Tevosian, William T. Pu J Clin Invest. 2009;119(6):1462-1476. https://doi.org/10.1172/JCI38723. Research Article Cardiology Aberrant transcriptional regulation contributes to the pathogenesis of both congenital and adult forms of heart disease. While the transcriptional regulator friend of Gata 2 (FOG2) is known to be essential for heart morphogenesis and coronary development, its tissue-specific function has not been previously investigated. Additionally, little is known about the role of FOG2 in the adult heart. Here we used spatiotemporally regulated inactivation of Fog2 to delineate its function in both the embryonic and adult mouse heart. Early cardiomyocyte-restricted loss of Fog2 recapitulated the cardiac and coronary defects of the Fog2 germline murine knockouts. Later cardiomyocyte-restricted loss ofF og2 (Fog2MC) did not result in defects in cardiac structure or coronary vessel formation. However, Fog2MC adult mice had severely depressed ventricular function and died at 8–14 weeks. Fog2MC adult hearts displayed a paucity of coronary vessels, associated with myocardial hypoxia, increased cardiomyocyte apoptosis, and cardiac fibrosis. Induced inactivation of Fog2 in the adult mouse heart resulted in similar phenotypes, as did ablation of the FOG2 interaction with the transcription factor GATA4. Loss of the FOG2 or FOG2-GATA4 interaction altered the expression of a panel of angiogenesis-related genes. Collectively, our data indicate that FOG2 regulates adult heart function and coronary angiogenesis.

Disruption of Fibroblast Growth Factor Signal

Experimental Design:The expression of 22 FGF and4 FGF receptor (FGFR) genes in18prima- ry tumors andfive cell lines of synovial sarcoma were analyzedby reverse transcription-PCR. Effects of recombinant FGF2, FGF8, andFGF18 for the activation of mitogen-activatedprotein kinase (MAPK) andthe growth of synovial sarcoma cell lines were analyzed.Growth inhibitory effects of FGFR inhibitors on synovial sarcoma cell lines were investigated in vitro and in vivo. Results: Synovial sarcoma cell lines expressedmultiple FGF genes especially those expressed in neural tissues, among which FGF8 showedgrowth stimulatory effects in all synovial sarcoma cell lines. FGF signals in synovial sarcoma induced the phosphorylation of extracellular signal ^ regulatedkinase (ERK1/2) andp38MAPK but not c-Jun NH 2-terminal kinase. Disruption of the FGF signaling pathway in synovial sarcoma by specific inhibitors of FGFR causedcell cycle ar- rest leading to significant growth inhibition both in vitro and in vivo.Growthinhibitionbythe FGFR inhibitor was associatedwith a down-regulation of phosphorylatedERK1/2 but not p38MAPK, andan ERK kinase inhibitor also showedgrowth inhibitory effects for synovial sar- coma, indicating that the growth stimulatory effect of FGF was transmitted through the ERK1/2. -

Fibroblast Growth Factor 12 Is Expressed in Spiral and Vestibular

FGF12 is a fbroblast growth factor homologous factor, a subset of the FGF superfamily. To date, its localisation and function in the inner ear have not been determined. Here, we show that FGF12 mRNA is localised in spiral ganglion neurons (SGNs) and the vestibular ganglion. We also show that FGF12 protein is localised in SGNs, the vestibular ganglion, and nerve fbres extending beneath hair cells. Moreover, we investigated FGF12 function in auditory and vestibular systems using Fgf12-knockout (FGF12-KO) mice generated with CRISPR/Cas9 technology. Our results show that the inner ear morphology of FGF12-KO mice is not signifcantly diferent compared with wild-type mice. However, FGF12-KO mice exhibited an increased hearing threshold, as measured by the auditory brainstem response, as well as defcits in rotarod and balance beam performance tests. These results suggest that FGF12 is necessary for normal auditory and equilibrium function. Hearing loss is a common problem in people of all ages. Te World Health Organization reports that 360 million people worldwide have hearing loss, with 32 million being children1. -

The aim of this study was to evaluate the FGF19 signals responsible for the progression of HCC arising from fatty liver. Results: FGF19 level was significantly increased in the HCC patients’ serum compared to non-HCC controls. The IHC results demonstrated significant increases of protein expressions of FGF19, FGFR4 and EpCAM in specimens with fatty liver, NASH, cirrhosis, and HCC compared to healthy liver tissue. There was a significant positive correlation between the protein expressions (FGF19, FGFR4, and EpCAM) and histopathologic changes from FL to HCC. Furthermore, FGF19 was positively correlated with FGFR4 and with EpCAM. -

FGF21 acutely induced ERK phosphorylation and inhibited Cyp7A1 mRNA expression in primary hepatocytes and in different rodent models, although less potently than recombinant human FGF19. Long-term administration of FGF21 in mice fed a standard chow diet resulted in a 50–60% decrease in bile acid levels in the liver and small intestines and consequently a 60% reduction of bile acid pool size. In parallel, colonic and fecal bile acid was decreased, whereas fecal cholesterol and fatty acid excretions were elevated. -
Age-Driven Developmental Drift in the Pathogenesis of Idiopathic Pulmonary Fibrosis

Correspondence: Moisés Selman, Instituto Nacional de Enfermedades Respiratorias, Tlalpan 4502, CP 14080, México DF, México. E-mail: [email protected] ABSTRACT Idiopathic pulmonary fibrosis (IPF) is a progressive and usually lethal disease of unknown aetiology. A growing body of evidence supports that IPF represents an epithelial-driven process characterised by aberrant epithelial cell behaviour, fibroblast/myofibroblast activation and excessive accumulation of extracellular matrix with the subsequent destruction of the lung architecture. The mechanisms involved in the abnormal hyper-activation of the epithelium are unclear, but we propose that recapitulation of pathways and processes critical to embryological development associated with a tissue specific age-related stochastic epigenetic drift may be implicated. These pathways may also contribute to the distinctive behaviour of IPF fibroblasts. Genomic and epigenomic studies have revealed that wingless/ Int, sonic hedgehog and other developmental signalling pathways are reactivated and deregulated in IPF. Moreover, some of these pathways cross-talk with transforming growth factor-β activating a profibrotic feedback loop. The expression pattern of microRNAs is also dysregulated in IPF and exhibits a similar expression profile to embryonic lungs. In addition, senescence, a process usually associated with ageing, which occurs early in alveolar epithelial cells of IPF lungs, likely represents a conserved programmed developmental mechanism.
