OBJECTIVE Dystrophin, the missing or defective protein in Duchenne muscular dystrophy, is expressed not only in muscle cells but also in vascular endothelial cells (ECs). In this study, we assessed the effects of dystrophin deficiency on the angiogenic capacities of ECs. APPROACH AND RESULTS We isolated vascular ECs from mdx mice, the murine equivalent of(More)
The Hedgehog (Hh) pathway is a crucial regulator of muscle development during embryogenesis. We have previously demonstrated that Sonic hedgehog (Shh) regulates postnatal myogenesis in the adult skeletal muscle both directly, by acting on muscle satellite cells, and indirectly, by promoting the production of growth factors from interstitial fibroblasts.(More)
Chronic fatigue immune dysfunction syndrome (CFIDS) is a recently recognized illness characterized by debilitating fatigue as well as immunological and neurological abnormalities [Straus, S.E. (1988) J. Inf. Dis. 157, 405-412]. Once thought to be caused by Epstein-Barr virus, it is now thought to have a different but unknown etiology. We evaluated 30 adult(More)
Recently the influence of polymorphisms of different genes involved in metabolism of chemoterapic agents have been studied especially in childhood acute lymphoblastic leukemia (ALL). We evaluated the influence of C677T and A1298C methylenetetrahydrofolate reductase (MTHFR) polymorphisms on time to relapse and survival and on methotrexate (MTX) toxicity in(More)
BACKGROUND Low folate intake and changes in folate metabolism due to polymorphisms in the methylentetrahydrofolate reductase (MTHFR) gene have been associated with myelomagenesis. However, controversial data have been published regarding a protective role of variant alleles of MTHFR on MM. PATIENTS AND METHODS To investigate the influence of two common(More)
We have previously shown that the signaling pathway of the embryonic morphogen Sonic hedgehog (Shh) is recapitulated in the postnatal skeletal muscle in response to ischemia. We have also demonstrated that Shh is an indirect angiogenic agent upregulating various families of angiogenic growth factors and that Shh gene therapy improves angiogenesis and heart(More)
Few data are available to date on the dose of oral valganciclovir as cytomegalovirus (CMV) preemptive therapy in stem cell transplantation patients. This study aimed to evaluate the efficacy and safety of low-dose valganciclovir (900 mg/day) as preemptive treatment in allotransplanted recipients. Valganciclovir was used in 34 patients who underwent(More)
