Disruption of Fibroblast Growth Factor Signal
Cancer Therapy: Preclinical Disruption of Fibroblast Growth Factor Signal Pathway Inhibits the Growth of Synovial Sarcomas: Potential Application of Signal Inhibitors to MolecularTarget Therapy Ta t s u y a I s hi b e , 1, 2 Tomitaka Nakayama,2 Ta k e s h i O k a m o t o, 1, 2 Tomoki Aoyama,1Koichi Nishijo,1, 2 Kotaro Roberts Shibata,1, 2 Ya s u ko Shim a ,1, 2 Satoshi Nagayama,3 Toyomasa Katagiri,4 Yusuke Nakamura, 4 Takashi Nakamura,2 andJunya Toguchida 1 Abstract Purpose: Synovial sarcoma is a soft tissue sarcoma, the growth regulatory mechanisms of which are unknown.We investigatedthe involvement of fibroblast growth factor (FGF) signals in synovial sarcoma andevaluatedthe therapeutic effect of inhibiting the FGF 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. -
Different Fgfs Have Distinct Roles in Regulating Neurogenesis After Spinal Cord Injury in Zebrafish Yona Goldshmit1,2, Jean Kitty K
Goldshmit et al. Neural Development (2018) 13:24 https://doi.org/10.1186/s13064-018-0122-9 RESEARCHARTICLE Open Access Different Fgfs have distinct roles in regulating neurogenesis after spinal cord injury in zebrafish Yona Goldshmit1,2, Jean Kitty K. Y. Tang1, Ashley L. Siegel1, Phong D. Nguyen1, Jan Kaslin1, Peter D. Currie1 and Patricia R. Jusuf1,3* Abstract Background: Despite conserved developmental processes and organization of the vertebrate central nervous system, only some vertebrates including zebrafish can efficiently regenerate neural damage including after spinal cord injury. The mammalian spinal cord shows very limited regeneration and neurogenesis, resulting in permanent life-long functional impairment. Therefore, there is an urgent need to identify the cellular and molecular mechanisms that can drive efficient vertebrate neurogenesis following injury. A key pathway implicated in zebrafish neurogenesis is fibroblast growth factor signaling. Methods: In the present study we investigated the roles of distinctfibroblastgrowthfactormembersandtheir receptors in facilitating different aspects of neural development and regeneration at different timepoints following spinal cord injury. After spinal cord injury in adults and during larval development, loss and/or gain of Fgf signaling was combined with immunohistochemistry, in situ hybridization and transgenes marking motor neuron populations in in vivo zebrafish and in vitro mammalian PC12 cell culture models. Results: Fgf3 drives neurogenesis of Islet1 expressing motor neuron subtypes and mediate axonogenesis in cMet expressing motor neuron subtypes. We also demonstrate that the role of Fgf members are not necessarily simple recapitulating development. During development Fgf2, Fgf3 and Fgf8 mediate neurogenesis of Islet1 expressing neurons and neuronal sprouting of both, Islet1 and cMet expressing motor neurons. -

The Biology of Hepatocellular Carcinoma: Implications for Genomic and Immune Therapies Galina Khemlina1,4*, Sadakatsu Ikeda2,3 and Razelle Kurzrock2
Khemlina et al. Molecular Cancer (2017) 16:149 DOI 10.1186/s12943-017-0712-x REVIEW Open Access The biology of Hepatocellular carcinoma: implications for genomic and immune therapies Galina Khemlina1,4*, Sadakatsu Ikeda2,3 and Razelle Kurzrock2 Abstract Hepatocellular carcinoma (HCC), the most common type of primary liver cancer, is a leading cause of cancer-related death worldwide. It is highly refractory to most systemic therapies. Recently, significant progress has been made in uncovering genomic alterations in HCC, including potentially targetable aberrations. The most common molecular anomalies in this malignancy are mutations in the TERT promoter, TP53, CTNNB1, AXIN1, ARID1A, CDKN2A and CCND1 genes. PTEN loss at the protein level is also frequent. Genomic portfolios stratify by risk factors as follows: (i) CTNNB1 with alcoholic cirrhosis; and (ii) TP53 with hepatitis B virus-induced cirrhosis. Activating mutations in CTNNB1 and inactivating mutations in AXIN1 both activate WNT signaling. Alterations in this pathway, as well as in TP53 and the cell cycle machinery, and in the PI3K/Akt/mTor axis (the latter activated in the presence of PTEN loss), as well as aberrant angiogenesis and epigenetic anomalies, appear to be major events in HCC. Many of these abnormalities may be pharmacologically tractable. Immunotherapy with checkpoint inhibitors is also emerging as an important treatment option. Indeed, 82% of patients express PD-L1 (immunohistochemistry) and response rates to anti-PD-1 treatment are about 19%, and include about 5% complete remissions as well as durable benefit in some patients. Biomarker-matched trials are still limited in this disease, and many of the genomic alterations in HCC remain challenging to target. -

Markers of Liver Regeneration—The Role of Growth Factors and Cytokines
Hoffmann et al. BMC Surgery (2020) 20:31 https://doi.org/10.1186/s12893-019-0664-8 RESEARCH ARTICLE Open Access Markers of liver regeneration—the role of growth factors and cytokines: a systematic review Katrin Hoffmann*†, Alexander Johannes Nagel†, Kazukata Tanabe, Juri Fuchs, Karolin Dehlke, Omid Ghamarnejad, Anastasia Lemekhova and Arianeb Mehrabi Abstract Background: Post-hepatectomy liver failure contributes significantly to postoperative mortality after liver resection. The prediction of the individual risk for liver failure is challenging. This review aimed to provide an overview of cytokine and growth factor triggered signaling pathways involved in liver regeneration after resection. Methods: MEDLINE and Cochrane databases were searched without language restrictions for articles from the time of inception of the databases till March 2019. All studies with comparative data on the effect of cytokines and growth factors on liver regeneration in animals and humans were included. Results: Overall 3.353 articles comprising 40 studies involving 1.498 patients and 101 animal studies were identified and met the inclusion criteria. All included trials on humans were retrospective cohort/observational studies. There was substantial heterogeneity across all included studies with respect to the analyzed cytokines and growth factors and the described endpoints. Conclusion: High-level evidence on serial measurements of growth factors and cytokines in blood samples used to predict liver regeneration after resection is still lacking. To address -

Par Guillaume Romain Département de microbiologie et infectiologie Mémoire présentée à la Faculté de médecine et des sciences de la santé Faculté de médecine et sciences de la santé, Université de Sherbrooke, Sherbrooke, Québec, Canada, J1H 5N4 Fibroblast Growth Factor 19 (FGF19 chez l’humain ; FGF15 chez la souris) est un régulateur central du métabolisme hépatique. Cette molécule a un impact important au niveau de la différentiation neurologique et de l’oreille interne au stade fœtal. À l’âge adulte, le patron d’expression est restreint au système gastro-intestinal. Contrairement aux autres membres de la superfamille des FGFs, FGF19/15 agit de manière endocrine car il n’est pas retenu par la matrice extracellulaire et peut rejoindre la circulation sanguine. L’expression de FGF19/15 est induite par les acides biliaires au niveau de l’intestin grêle, plus précisément l’iléon. Les acides biliaires lient le récepteur nucléaire Farnesoid-X- Receptor (FXR) qui peut ensuite s’hétérodimériser avec Retinoid-X-Receptor (RXR) pour se lier au promoteur de FGF19/15, ce qui enclenche son expression.
