Dendritic cells (DCs) are central cells in the development of antitumor immune responses, but the number and function of these cells can be altered in various cancers. Whether these cells are affected during the development of melanoma is not known. We investigated the presence, phenotype, and functionality of circulating myeloid DCs (MDCs) and plasmacytoid(More)
CONTEXT The National French federation of comprehensive cancer centres (FNCLCC) and the French society of dermatology (SFD) initiated together the update of clinical practice guideline for the management of patients with cutaneous melanoma in collaboration with the French national cancer institute and with specialists from French public universities,(More)
BACKGROUND Melanoma incidence is higher in patients affected by Parkinson's disease (PD) and vice versa, but the genetic link shared by both diseases is unknown. As PARK2 is both a tumor suppressor gene and frequently mutated in young onset PD, we evaluated the role of PARK2 in melanoma predisposition and progression. METHODS An in-depth PARK2 gene dosage(More)
Cell migration, growth, and survival is modulated by focal adhesions linking extracellular matrix proteins, cell adhesion molecules, and the cytoskeleton. Zyxin is a focal adhesion phosphoprotein that shares homology with Listeria ActA protein in promoting actin filament assembly; it also has specialized protein-protein interface domains implicating an(More)
In purified system zinc has been shown to have an antioxidant role. Its effects on the resistance of cultured cells towards oxidative stress in vitro were examined. Diploid human skin fibroblasts were grown for 21 d in culture media (RPMI 1640 containing 15% fetal calf serum) added with different zinc (Zn) concentrations (100, 125, and 150μM as Zinc chlorur(More)
Dendritic cells (DC), considered as immunological sentinels of the organism since they are antigen presenting cells, create the link between innate and adaptive immunity. DC include myeloid dendritic cells (MDC) and plasmacytoid dendritic cells (PDC). The presence of PDC, cells capable of producing large quantities of interferon alpha (IFN-alpha) in(More)
In immunocompromised patients, cooperative effects of human papillomavirus (HPV) and ultraviolet (UV) radiation have been postulated in the development of non-melanoma skin cancers. The tumor suppressor p53 is a key component of the cellular response to genotoxic agents, such as UV radiation. We have previously demonstrated that in HPV16-infected cells, a(More)
Sentinel lymph node procedure for cutaneous melanoma is largely used and sentinel lymph node status is an important prognostic factor. Few French centers have reported their experience and data. We analysed technique feasibility, recurrence-free and overall-survival rates at 36 and 60 months for the first 62 patients submitted to this technique. The(More)
BACKGROUND Voriconazole long-term therapy is suspected to induce cutaneous squamous cell carcinoma (SCC), as suggested by 18 case reports worldwide and 3 retrospective studies. METHODS To better characterize the natural history of these potentially voriconazole-associated tumors, a nationwide call for notification of skin cancers and other skin lesions(More)
