| 1 | Epigenetic mechanisms in non-alcoholic fatty liver disease:An emerging field显示文摘Non-alcoholic fatty liver disease(NAFLD) is an emerging health concern in both developed and non-developed world, encompassing from simple steatosis to nonalcoholic steatohepatitis(NASH), cirrhosis and liver cancer. Incidence and prevalence of this disease are increasing due to the socioeconomic transition and change to harmful diet. Currently, gold standard method in NAFLD diagnosis is liver biopsy, despite complications and lack of accuracy due to sampling error. Further, pathogenesis of NAFLD is not fully understood, but is well-known that obesity, diabetes and metabolic derangements played a major role in disease development and progression. Besides, gut microbioma and host genetic and epigenetic background could explain considerable interindividual variability. Knowledge that epigenetics, heritable events not caused by changes in DNA sequence, contribute to development of diseases has been a revolution in the last few years. Recently, evidences are accumulating revealing the important role of epigenetics in NAFLD pathogenesis and in NASH genesis. Histone modifications, changes in DNA methylation and aberrant profiles or micro RNAs could boost development of NAFLD and transition into clinical relevant status. PNPLA3 genotype GG has been associated with a more progressive disease and epigenetics could modulate this effect. The impact of epigenetic on NAFLD progression could deserve further applications on therapeutic targets together with future non-invasive methods useful for the diagnosis and staging of NAFLD. | Rocío Gallego-Durán Manuel Romero-Gómez | 2015 | World Journal of Hepatology2015，7，24： | 8 |
| 2 | ADV36 adipogenic adenovirus in human liver disease显示文摘obesity and liver steatosis are usually described as related diseases.obesity is regarded as exclusive consequence of an imbalance between food intake and physical exercise,modulated by endocrine and genetic factors.Non-alcoholic fatty liver disease(NAFLD),is a condition whose natural history is related to,but not completely explained by over-nutrition,obesity and insulin resistance.There is evidence that environmental infections,and notably adipogenic adenoviruses(ADV)infections in humans,are associated not only with obesity,which is sufficiently established,but also with allied conditions,such as fatty liver.In order to elucidate the role,if any,of previous ADV36 infection in humans,we investigated association of ADV36-ADV37 seropositivity with obesity and fatty liver in humans.Moreover,the possibility that lifestyle-nutritional intervention in patients with NAFLD and different ADV36 seropositive status,achieves different clinical outcomes on ultrasound bright liver imaging,insulin resistance and obesity was challenged.ADV36 seropositive patientshave a more consistent decrease in insulin resistance,fatty liver severity and body weight in comparison with ADV36 seronegative patients,indicating a greater responsiveness to nutritional intervention.These effects were not dependent on a greater pre-interventional body weight and older age.These results imply that no obvious disadvantage-and,seemingly,that some benefit-is linked to ADV36 seropositivity,at least in NAFLD.ADV36 previous infection can boost weight loss and recovery of insulin sensitivity under interventional treatment. | Francesca M Trovato Daniela Catalano Adriana Garozzo G Fabio Martines Clara Pirri Guglielmo M Trovato | 2014 | World Journal of Gastroenterology2014，20，40： | 1 |
