Biochemical and chemical characterization of Cynara cardunculus L. extract and its potential use as co-adjuvant therapy of chronic myeloid leukemia

2017

Abstract Ethnopharmacological relevance Ancient mediterranean diet was characterized by consuming the spontaneous forms of Cynara cardunculus L. (CCL), commonly called artichoke. Cultivated and/or spontaneous forms of CC studies have demonstrated that methanol extract of CCL flower and/or cynaropicrin showed remarkable anti-proliferative activity in vitro models of leukocyte cancer cell. Aim of the study Chronic myeloid leukemia (CML) is associated with a reciprocal translocation of the long arms of chromosomes 9 and 22 generating the BCR/ABL fusion gene, translated in the p210 BCR/ABL oncoprotein kinase. This chimeric protein is the target of a kinase inhibitor, imatinib, but the developme…

FINE STRUCTURE OF THE ABSORBING LYMPHATIC VESSEL AND INTRAVASATION MODALITY OF THE CANCER CELL

2007

The topografic distribution and the fine structure of the tumor-associated absorbing lymphatic vessel in the B16 Melanoma and T84 adenocarcinoma subcutaneous tumor mass of nude mice and in adenocarcinoma mouse prostate in transgenic mice were studied to demonstrate the modality of the cancer cell transendothelial migration and the role of the lymphatic pathway in the metastatic diffusion. Furthermore, the structural characteristics of the lymphatic vascular system canalisation, that allow to discriminate between the vessels with high absorbent capacity, distinctive of the mucous and submucous network and vessels with lymph flow and conduction function (precollectors, pre- and postlymph noda…

Lentiviral-Mediated Gene Therapy in Fanconi Anemia-A Mice Reveals Long-Term Engraftment and Continuous Turnover of Corrected HSCs

2015

International audience; Fanconi anemia is a DNA repair-deficiency syndrome mainly characterized by cancer predisposition and bone marrow failure. Trying to restore the hematopoietic function in these patients, lentiviral vector-mediated gene therapy trials have recently been proposed. However, because no insertional oncogenesis studies have been conducted so far in DNA repair-deficiency syndromes such as Fanconi anemia, we have carried out a genome-wide screening of lentiviral insertion sites after the gene correction of Fanca-/- hematopoietic stem cells (HSCs), using LAM-PCR and 454-pyrosequencing. Our studies first demonstrated that transduction of Fanca-/- HSCs with a lentiviral vector d…

Inhibition of human T-cell leukemia virus type I replication in primary human T cells that express antisense RNA

1989

The human T-cell leukemia virus type I is associated with adult T-cell leukemia-lymphoma in humans, a disease which is induced by a malignant transformation of T lymphocytes. Retrovirus vectors carrying human T-cell leukemia virus type I-derived sequences in reversed transcriptional orientation were used to express antisense RNA transcripts in primary human leukocytes. Human T-cell leukemia virus type I replication and virus-mediated immortalization were inhibited in cells harboring antisense constructs. This study suggests that retrovirus-mediated antisense RNA inhibition can be used to protect primary human T-lymphocytes from human T-cell leukemia virus type I-mediated cell transformation.

Brain erythropoietin fine-tunes a counterbalance between neurodifferentiation and microglia in the adult hippocampus

2021

In adult cornu ammonis hippocampi, erythropoietin (EPO) expression drives the differentiation of new neurons,independent of DNA synthesis, and increases dendritic spine density. This substantial brain hardwareupgrade is part of a regulatory circle: during motor-cognitive challenge, neurons experience ‘‘functional’’hypoxia, triggering neuronal EPO production, which in turn promotes improved performance. Here, weshow an unexpected involvement of resident microglia. During EPO upregulation and stimulated neurodifferentiation,either by functional or inspiratory hypoxia, microglia numbers decrease. Treating mice with recombinanthuman (rh)EPO or exposure to hypoxia recapitulates these changes and…

Internet Gaming Disorder profiles and their associations with social engagement behaviours.

2021

Abstract Internet Gaming Disorder (IGD), describes the abuse of Internet games with detrimental impact to the real-life social engagement of some gamers. Indeed, evidence suggests that gamers differ on the severity and way in which they express IGD symptoms, as well as their social engagement behaviours. The present study aimed to: a) profile gamers regarding their experience of IGD symptoms and; b) examine how different IGD profiles varied on social engagement behaviours. Methods: A sample consisting of 1032 gamers (18–72 years, Mage = 24) was assessed with the Internet Gaming Disorder Scale 9 Items Short Form (IGDS9-SF) and social engagement questions regarding their participation in empl…
