Hepatic miR-34a expression is elevated in diet-induced or genetically obese mice and patients with non-alcoholic steatohepatitis (NASH), yet hepatocyte miR-34a's role in the progression of non-alcoholic fatty liver disease (NAFLD) from non-alcoholic fatty liver (NAFL) to NASH remains to be elucidated.

Mice overexpressing or deficient in hepatocyte miR-34a and control mice were fed a diet enriched in fats, cholesterol, and fructose (HFCF) to induce NASH. C57BL/6 mice with NASH were treated with an miR-34a inhibitor or a scramble control oligo. The effect of miR-34a on the development, progression, and reversal of NAFLD was determined.

The hepatocyte-specific expression of miR-34a aggravated HFCF diet-induced NAFLD. https://www.selleckchem.com/products/abbv-744.html In contrast, germline or adult-onset deletion of hepatocyte miR-34a attenuated the development and progression of NAFLD. In addition, pharmacological inhibition of miR-34a reversed HFCF diet-induced steatohepatitis. Mechanistically, hepatocyte miR-34a regulated the development and progression of NAFLD by inducing lipid absorption, lipogenesis, inflammation, and apoptosis but inhibiting fatty acid oxidation.

Hepatocyte miR-34a is an important regulator in the development and progression of NAFLD. MiR-34a may be a useful target for treating NAFLD.

As a microRNA (miRNA), miRNA125b (miR-125b) plays an important role in the prediction and prognosis of HCC. In the past 10 years, with increasing research on miR-125b and HCC, the molecular mechanism of its relationship with the development of HCC has been elucidated. MiR-125b inhibits the development of HCC and is highly accurate in predicting HCC and is therefore a valuable predictive marker of HCC. This article summarizes the clinical application of miR-125b in HCC and the potential mechanism of its involvement in the progression of HCC.

The factors predicting hepatocellular carcinoma (HCC) occurrence in chronic hepatitis B need to be precisely known to improve its detection. We identified pathways and individual predictive factors associated with HCC in the ANRS CO22 HEPATHER cohort.

The study analyzed HBV-infected patients recruited at 32 French expert hepatology centers from August 6, 2012, to December 31, 2015. We excluded patients with chronic HCV, HDV and a history of HCC, decompensated cirrhosis or liver transplantation. Structural equation models were developed to characterize the causal pathways leading to HCC occurrence. The association between clinical characteristics (age, gender, body-mass index, liver fibrosis, alcohol consumption, smoking status, diabetes, hypertension, dyslipidemia, alpha-fetoprotein, HBV DNA levels, antiviral therapy) and incident HCC was quantified.

Among the 4489 patients included, 33 patients reported incident HCC. The median follow-up was 45.5 months. Age (β = 0.18 by decade, 95% CI 0.14-0.23), male gender (β = 0.23, 95% CI 0.18-0.29), metabolic syndrome (β = 0.28, 95% CI 0.22-0.33), alcohol consumption (β = 0.09, 95% CI 0.05-0.14) and HBV DNA (β = 0.25, 95% CI 0.170.34) had a significant and direct effect on the occurrence of advanced liver fibrosis. Liver fibrosis (β = 0.71, 95% CI 0.55-0.87) predicted, in turn, the occurrence of HCC.

Liver fibrosis mediates the effects of age, gender, alcohol, metabolic syndrome and HBV DNA on the occurrence of HCC. Elderly men with chronic hepatitis B, risky alcohol use, advanced liver fibrosis, metabolic syndrome and high HBV DNA levels should be monitored closely to detect the development of HCC.

Some unspecific endoscopic features may assist to distinguish polypoid ICD from true polyps. This differentiation bears relevance for the therapeutic approach, as colonic polyps require snare polypectomy, a practice which may be associated with colonic perforation in case of true ICD. The endoscopist, therefore, should be aware of the likelihood of detecting these lesions during colonoscopy. A close inspection and a gentle probing could assist in a correct diagnosis and avoid risky procedures such as biopsy or polypectomy. Rarely, a neoplasm arising over an ICD and its treatment has been described. We reported two cases, one of which with dysplasia, and their treatment, and reviewed all the ICD endoscopic cases so far reported in the literature, remarking the possibility of finding pedunculated ICDs or neoplasm arising over an ICD.

The use of chemotherapy (CT) near the end-of-life (EOL) is an important issue in oncology since it could degrade quality of life. CT near EOL is still poorly studied, with no dedicated study in gastrointestinal (GI) cancer patients.

To analyze in GI cancer patients the factors associated with the use of CT within 3- and 1-month before patients' death.

All consecutive patients who died from a GI cancer in 10 French tertiary care hospitals during 2014 were included in this retrospective study. Clinical, demographical and biological data were collected and compared between patients receiving or not CT within 3- and 1-month before death. Variables associated with overall survival (OS) was also determined using of univariate and multivariate analyses with a Cox model.

Four hundred and thirty-seven patients with a metastatic GI cancer were included in this study. Among them, 293 pts (67.0%) received CT within 3-months before death, and 121 pts (27.7%) received CT within 1-month before death. Patients receiving CT within 3-months before death were significantly younger (median age 65.
