Successful rechallenge with Erwinia chrysanthemi asparaginase after pegaspargase-induced hypertriglyceridemia: a case report.

Polyethylene-glycolated -derived l-asparaginase (pegaspargase, pASP) is an essential component of paediatric-inspired regimens for the treatment of acute lymphoblastic leukaemia/lymphoma; nonetheless, is characterised by severe and potentially life-threatening toxicities, such as hypertriglyceridemia. Grades 3-4 events have been reported in ~1%-18% of paediatric patients and in sparse reports in adults. There is limited evidence on the safety of asparaginase rechallenge in patients experiencing severe pASP-related hypertriglyceridemia.

Dramatic Suppression of Lipogenesis and No Increase in Beta-Oxidation Gene Expression Are among the Key Effects of Bergamot Flavonoids in Fatty Liver Disease.

Bergamot flavonoids have been shown to prevent metabolic syndrome, non-alcoholic fatty liver disease (NAFLD) and stimulate autophagy in animal models and patients. To investigate further the mechanism of polyphenol-dependent effects, we performed a RT2-PCR array analysis on 168 metabolism, transport and autophagy-related genes expressed in rat livers exposed for 14 weeks to different diets: standard, cafeteria (CAF) and CAF diet supplemented with 50 mg/kg of bergamot polyphenol fraction (BPF). CAF diet caused a strong upregulation of gluconeogenesis pathway (, ) and a moderate (>1.

Autophagy and neuroprotection in astrocytes exposed to 6-hydroxydopamine is negatively regulated by NQO2: relevance to Parkinson's disease.

Dopaminergic degeneration is a central feature of Parkinson's disease (PD), but glial dysfunction may accelerate or trigger neuronal death. In fact, astrocytes play a key role in the maintenance of the blood-brain barrier and detoxification. 6-hydroxydopamine (6OHDA) is used to induce PD in rodent models due to its specific toxicity to dopaminergic neurons, but its effect on astrocytes has been poorly investigated.
