1. Novel patient-derived xenograft and cell line models for therapeutic testing of pediatric liver cancer.

    Journal of Hepatology 65(2):325 (2016) PMID 27117591

    Pediatric liver cancer is a rare but serious disease whose incidence is rising, and for which the therapeutic options are limited. Development of more targeted, less toxic therapies is hindered by the lack of an experimental animal model that captures the heterogeneity and metastatic capability ...
  2. Liver is liver and blood is blood, and finally the twain have met.

    Journal of Hepatology 65(2):245 (2016) PMID 27221221

  3. Development and rescue of human familial hypercholesterolaemia in a xenograft mouse model.

    Nature Communications 6:7339 (2015) PMID 26081744 PMCID PMC4557302

    Diseases of lipid metabolism are a major cause of human morbidity, but no animal model entirely recapitulates human lipoprotein metabolism. Here we develop a xenograft mouse model using hepatocytes from a patient with familial hypercholesterolaemia caused by loss-of-function mutations in the low...
  4. Sonic Hedgehog-induced proliferation requires specific Gα inhibitory proteins.

    Journal of Biological Chemistry 286(10):8067 (2011) PMID 21209076 PMCID PMC3048693

    Proliferation of cerebellar granular neuronal precursors (CGNPs) is mediated by Sonic Hedgehog (Shh), which activates the Patched and Smoothened (Smo) receptor complex. Although its protein sequence suggests that Smo is a G protein coupled receptor (GPCR), the evidence that this receptor utilize...
  5. Sonic-hedgehog-mediated proliferation requires the localization of PKA to the cilium base.

    Journal of Cell Science 123(Pt 1):62 (2010) PMID 20016067

    Cerebellar granular neuronal precursors (CGNPs) proliferate in response to the mitogenic activity of Sonic hedgehog (Shh), and this proliferation is negatively regulated by activation of cAMP-dependent protein kinase (PKA). In the basal state, the PKA catalytic subunits (C-PKA) are inactive beca...
  6. Probucol increases glutathione peroxidase-1 activity and displays long-lasting protection against methylmercury toxicity in cerebellar granule cells.

    Toxicological Sciences 112(2):416 (2009) PMID 19770487

    Methylmercury (MeHg) is an environmental neurotoxicant whose molecular mechanisms underlying toxicity remain elusive. Here, we investigated molecular events involved in MeHg-induced neurotoxicity in cultured cerebellar granule cells (CGCs) as well as potential protective strategies for such toxi...
  7. Bone morphogenetic protein 2 opposes Shh-mediated proliferation in cerebellar granule cells through a TIEG-1-based regulation of Nmyc.

    Journal of Biological Chemistry 282(51):37170 (2007) PMID 17951258

    Nmyc is a potent regulator of cell cycle in cerebellar granular neuron precursors (CGNPs) and has been proposed to be the main effector of Shh (Sonic hedgehog) proliferative activity. Nmyc ectopic expression is sufficient to promote cell autonomous proliferation and can lead to tumorigenesis. Bo...
