[Management of immune checkpoint inhibitors-induced liver toxicity in cancer].

Fanny Lebossé, Brigitte Bancel, Massimo Levrero, Philippe Merle,

Pharmacological immune checkpoint inhibitors (ICI) restore the anti-tumor properties of T-lymphocytes, but unfortunately can engender auto-immune-like disorders. Those, frequent and of variable severity, sometimes target the liver parenchyma. Liver toxicity of ICI firstly leads to alteration of liver function tests (ALFT) with a risk of clinical decompensation. The appearance of ... Read more >>

Inducing and Characterizing Vesicular Steatosis in Differentiated HepaRG Cells.

Silvia Di Cocco, Laura Belloni, Abigail D G Nunn, Debora Salerno, Silvia Piconese, Massimo Levrero, Natalia Pediconi,

Hepatic steatosis represents a metabolic dysfunction that results from an accumulation of triglyceride-containing lipid droplets in hepatocytes. Excessive fat accumulation leads to non-alcoholic fatty liver disease (NAFLD),  which is potentially reversible and may evolve into non-alcoholic steatohepatitis (NASH) and eventually cirrhosis and hepatocellular carcinoma (HCC). The molecular mechanisms linking lipid ... Read more >>

EZH2, JMJD3, and UTX epigenetically regulate hepatic plasticity inducing retro-differentiation and proliferation of liver cells.

Natalia Pediconi, Debora Salerno, Leonardo Lupacchini, Annapaola Angrisani, Giovanna Peruzzi, Enrico De Smaele, Massimo Levrero, Laura Belloni,

Modification of histones by lysine methylation plays a role in many biological processes, and it is dynamically regulated by several histone methyltransferases and demethylases. The polycomb repressive complex contains the H3K27 methyltransferase EZH2 and controls dimethylation and trimethylation of H3K27 (H3K27me2/3), which trigger gene suppression. JMJD3 and UTX have been ... Read more >>

In liver cirrhosis (LC), impaired intestinal functions lead to dysbiosis and possible bacterial translocation (BT). Bacteria or their byproducts within the bloodstream can thus play a role in systemic inflammation and hepatic encephalopathy (HE). We combined 16S sequencing, NMR metabolomics and network analysis to describe the interrelationships of members of ... Read more >>

Metformin is a commonly prescribed type II diabetes medication that exhibits promising anticancer effects. Recently, these effects were found to be associated, at least in part, with a modulation of microRNA expression. However, the mechanisms by which single modulated microRNAs mediate the anticancer effects of metformin are not entirely clear ... Read more >>

Ribavirin restores IFNα responsiveness in HCV-infected livers by epigenetic remodelling at interferon stimulated genes.

Barbara Testoni, David Durantel, Fanny Lebossé, Judith Fresquet, François Helle, Francesco Negro, Maria Francesca Donato, Massimo Levrero, Fabien Zoulim,

Caveats in the understanding of ribavirin (RBV) mechanisms of action has somehow prevented the development of better analogues able to further improve its therapeutic contribution in interferon (IFN)-based and direct antiviral agent-based regimens for chronic HCV or other indications. Here, we describe a new mechanism by which RBV modulates IFN-stimulated ... Read more >>
