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
www.nature.com/scientificreports OPEN Fibroblast growth factor 12 is expressed in spiral and vestibular ganglia and necessary for auditory Received: 5 February 2018 Accepted: 26 June 2018 and equilibrium function Published: xx xx xxxx Yukiko Hanada1,2, Yukiko Nakamura1, Yoshiyuki Ozono2, Yusuke Ishida1,3, Yasumitsu Takimoto1,2,4, Manabu Taniguchi5, Kazuya Ohata1,2, Yoshihisa Koyama1, Takao Imai2, Tetsuo Morihana2,6, Makoto Kondo1, Takashi Sato2, Hidenori Inohara2 & Shoichi Shimada1 We investigated fbroblast growth factor 12 (FGF12) as a transcript enriched in the inner ear by searching published cDNA library databases. 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. -

Here we described a relationship between Hippo pathway components and inflammation in healthy subjects. The plasma levels of cytokines and chemokines were used to define their inflammatory profile and classify them as normal, high and low producers of cytokines. Leukocytes from healthy subjects with inflammatory profile expressed the highest levels of MSTS1/MST2, SAV1, LATS1/LATS2, MOB1A/MOB1B and YAP genes. The group that overexpressed Hippo pathway-related genes secreted more IFN-ϒ and IFN-α2.
