Comparison of the chemopreventive efficacies of garlic powders with different alliin contents against aflatoxin B1 carcinogenicity in rats

2004

Garlic (Allium sativum) is well known for its beneficial effects on health and particularly for its chemopreventive potential against cancer. The present study was designed to compare the chemopreventive efficacies of several garlic powders with various levels of alliin, a precursor of active sulfur compounds. For this purpose we used the medium-term hepatocarcinogenesis protocol (resistant hepatocyte model), which allows the detection of preneoplasic foci expressing the placental form of glutathione S-transferase (GST-P) as an end-point. Rats were fed diets containing three garlic powders (5% of the diet) with various alliin contents for 3 weeks. Garlic powders were obtained from bulbs gro…

Isomer-nonspecific action of dichlorodiphenyltrichloroethane on aryl hydrocarbon receptor and G-protein-coupled receptor 30 intracellular signaling i…

2014

Abstract Extended residual persistence of the pesticide dichlorodiphenyltrichloroethane (DDT) raises concerns about its long-term neurotoxic effects. Little is known, however, about DDT toxicity during the early stages of neural development. This study demonstrated that DDT-induced apoptosis of mouse embryonic neuronal cells is a caspase-9-, caspase-3-, and GSK-3β-dependent process, which involves p,p’ -DDT-specific impairment of classical ERs. It also provided evidence for DDT-isomer-nonspecific alterations of AhR- and GPR30-mediated intracellular signaling, including changes in the levels of the receptor and receptor-regulated mRNAs, and also changes in the protein levels of the receptors…

Approssimazione all’edizione italiana della «Cronica generale d’Hispagna et del regno di Valenza» di Pere Antoni Beuter (Venezia, Gabriele Giolito de…

2013

Riassunto: Il presente saggio si propone come una prima approssimazione allo studio dell’edizioneitaliana della Cronaca generale d’Hispagna et del regno di Valenza di Pere Antoni Beuter, pubblicatanel 1556 a Venezia da Gabriele Giolito de’ Ferrari nella traduzione dello spagnolo Alfonso deUlloa. Quest’opera storiografica si inserisce in un contesto culturale importantissimo come quellodella Venezia del Cinquecento, particolarmente effervescente nel campo dell’editoria con figure diprim’ordine come Giolito e Ulloa. Il saggio si divide in tre momenti: il primo è costituito da unabreve introduzione sull’opera di Beuter e sulla traduzione di Ulloa; il secondo presenta la schedacatalografica del…

GADD45a physically and functionally interacts with TET1

2015

AbstractDNA demethylation plays a central role during development and in adult physiology. Different mechanisms of active DNA demethylation have been established. For example, Growth Arrest and DNA Damage 45-(GADD45) and Ten-Eleven-Translocation (TET) proteins act in active DNA demethylation but their functional relationship is unresolved. Here we show that GADD45a physically interacts – and functionally cooperates with TET1 in methylcytosine (mC) processing. In reporter demethylation GADD45a requires endogenous TET1 and conversely TET1 requires GADD45a. On GADD45a target genes TET1 hyperinduces 5-hydroxymethylcytosine (hmC) in the presence of GADD45a, while 5-formyl-(fC) and 5-carboxylcyto…

The role of red yeast rice (RYR) supplementation in plasma cholesterol control: A review and expert opinion.

2019

1. Preamble : Hypercholesterolemia is a major risk factor for atherosclerotic cardiovascular disease (ASCVD) [1]. Increased levels of low density lipoprotein cholesterol (LDL-C) are associated with an increased risk of coronary heart disease (CHD) and many clinical trials have shown that reducing LDL-C levels significantly reduced the CHD and CVD risk [[2], [3], [4], [5]]. Thus LDL-C-lowering is the main approach for the management of cardiovascular disease. Current guidelines suggest LDL-C levels targets based on the individual CV risk; such targets can be achieved by several means, which include both lifestyle changes and pharmacological approaches [6], with statins being the cornerstone …

Climate change and genetic structure of leading edge and rear end populations in a northwards shifting marine fish species, the corkwing wrasse (Symp…

2013

Published version of an article in the journal:PLoS ONE. Also available from the Public Library of Science: http://dx.doi.org/10.1371/journal.pone.0067492 Open Access One mechanism by which marine organisms may respond to climate shifts is range shifts. The corkwing wrasse (Symphodus melops) is a temperate fish species, inhabiting the coasts of Europe, that show strong indications of current as well as historical (ice-age) range shifts towards the north. Nine neutral microsatellite DNA markers were screened to study genetic signatures and spatial population structure over the entire geographic and thermal gradient of the species from Portugal to Norway. A major genetic break (FST  = 0.159 a…

Quantitative RT-PCR measurement of human cytochrome P-450s: application to drug induction studies.

2000

A quantitative RT-PCR assay has been developed that is able to measure the mRNA content of the major human CYPs (1A1, 1A2, 2A6, 2B6, 2C9, 2C19, 2D6, 2E1, 3A4, and 3A5). The technique is highly specific, reproducible, rapid, and sensitive enough to quantitate low and high abundant mRNAs. The PCR primers were selected to specifically match each CYP mRNA, to have a very close annealing temperature, and to render PCR products of similar sizes. The PCR conditions were designed to allow the simultaneous measurement of the various human liver CYPs in a single run. To achieve precise and reproducible quantitation of each cytochrome mRNA, a external standard (luciferase mRNA) is added to the probes …
