Changes in lipid metabolism are intimately related to cancer. Several classes of bioactive lipids play roles in the regulation of signaling pathways involved in neoplastic transformation and tumor growth and progression. The endocannabinoid system, comprising lipid-derived endocannabinoids, their G-protein-coupled receptors (GPCRs), and the enzymes for(More)
The mevalonate (MVA) pathway is an important metabolic pathway implicated in multiple aspects of tumorigenesis. In this study, we provided evidence that p53 induces the expression of a group of enzymes of the MVA pathway including 3'-hydroxy-3'-methylglutaryl-coenzyme A reductase, MVA kinase, farnesyl diphosphate synthase and farnesyl diphosphate farnesyl(More)
Statins are well known competitive inhibitors of hydroxymethylglutaryl-CoA reductase enzyme (HMG-CoA reductase), thus traditionally used as cholesterol-lowering agents. In recent years, more and more effects of statins have been revealed. Nowadays alterations of lipid metabolism have been increasingly recognized as a hallmark of cancer cells. Consequently,(More)
Emerging findings suggested the efficacy of the cannabinoid CB1 receptor antagonist rimonabant (SR141716) in several pathological conditions included tumours. In this study we investigated in vitro the effects of SR141716 on viability and the molecular pathways of methylcholanthrene-induced fibrosarcoma (Meth-A) cells and in vivo its anti-tumour properties(More)
We previously showed that methyl-F-anandamide, a stable analogue of the anandamide, inhibited the growth and the progression of cultured human breast cancer cells. As accumulating evidences indicate that the constitutive activation of the canonical Wnt pathway in human breast cancer may highlight a key role for aberrant activation of the β-catenin-TCF(More)
BACKGROUND Clinical use of porcine cell-based bioartificial liver (BAL) support in acute liver failure as bridging therapy for liver transplantation exposes the patient to the risk of transmission of porcine endogenous retroviruses (PERVs) to human. This risk may be enhanced when patients receive liver transplant and are subsequently immunosuppressed. As(More)
Herein we show that a majority of human brain tumor samples and cell lines over-expressed cannabinoid receptor CB1 as compared to normal human astrocytes (NHA), while uniformly expressed low levels of CB2. This finding prompted us to investigate the therapeutic exploitation of CB1 inactivation by SR141716 treatment, with regard to its direct and indirect(More)
iPA is a naturally occurring nucleoside with an isopentenyl moiety derived from the mevalonate pathway and a well-established anti-tumor activity. In analogy to the unique specificity for phosphoantigens, such as IPP, shown by human Vγ9Vδ2 T cells, here, we report for the first time the ability of iPA to selectively expand and directly target human NK(More)
Hutchinson-Gilford progeria syndrome is caused by mutations in the lamin A/C gene that lead to expression of a truncated, permanently farnesylated prelamin A variant called progerin. The accumulation of progerin at the nuclear envelope causes mis-shapen nuclei and results in progeroid syndromes. Previous studies in cells from individuals with(More)
The Polymerase Chain reaction technique has been used in order to detect and amplify a specific region of mtDNA, in a total DNA preparation extracted from the sperm of the sea urchin Arbacia lixula. The amplified fragment is the D-loop region which hybridizes with the homologous region extracted from the egg mtDNA. The results demonstrate that mtDNA is(More)
