An unsolved question is how platinum derivatives used for solid cancer therapy cause peripheral neuropathy in patients and apoptosis in "in vitro" models of chemotherapy-induced peripheral neuropathy. DRG neurons from E15 rat embryos were treated with toxic doses of oxaliplatin or cisplatin. Here, the role of MAPKs in neuronal apoptosis was studied. Both(More)
Retinoic acid (RA), an active metabolite of vitamin A, is a natural morphogen involved in development and differentiation of the nervous system. To elucidate signaling mechanisms involved in RA-induced neuritogenesis, we used human neuroblastoma SH-SY5Y cells, an established in vitro model for studying RA action, to examine the role of extracellular(More)
Epothilones are a novel class of microtubule-targeting anticancer agents that are neurotoxic. In this study, we investigated the epothilone B toxic effect in vitro and we characterized in vivo the general and neurological side effects of epothilone B administration in Wistar and Fischer rats. The in vitro experiments made it possible to explore a wide(More)
We report here the identification of a new shared human melanoma antigen recognized by a human leukocyte antigen (HLA)-A*68011-restricted cytotoxic T lymphocyte clone (CTL 128). The cDNA encoding this antigen is composed of a partially spliced form of the melanocyte differentiation antigen tyrosinase-related protein (TRP)-2, containing exons 1-4 with(More)
Paclitaxel is an antineoplastic drug which acts by enhancing tubulin polymerization. The induction of peripheral neuropathy is the main dose-limiting side-effect of paclitaxel treatment. In this study, the neurotoxic effect of this drug in dorsal root ganglion (DRG) explants was analyzed by measuring the neurite length of DRG explants exposed to nerve(More)
HLA-A2 § melanomas express common melanoma-associated antigens (Ags) recognized in vitro by autologous cytotoxic T lymphocytes (CTL). However, it is not known whether tumor Ags can drive in vivo a selective accumulation/expansion of Ag-specific, tumor-infiltrating T lymphocytes (TIL). Therefore, to evaluate this possibility, 39 CTL clones isolated from(More)
Dysregulation of receptor tyrosine kinases (RTKs) contributes to several aspects of oncogenesis including drug resistance. In melanoma, distinct RTKs have been involved in BRAF inhibitors (BRAFi) resistance, yet the utility of RTKs expression pattern to identify intrinsically resistant tumors has not been assessed. Transcriptional profiling of RTKs and(More)
Repeated intracerebroventricular (i.c.v.) microinjection of tumor necrosis factor-␣ (TNF-␣) into normal rats causes intramyelin and interstitial edema in the white matter of the spinal cord (SC). This response is identical to that observed in the SC white matter of rats made cobalamin (Cbl) deficient by total gastrectomy (TG). Immunoblot analysis showed(More)
Chemotherapy-induced peripheral neurotoxicity (CIPN) is a side effect limiting cisplatin (CDDP) and docetaxel (DOCE) treatment. Erythropoietin (EPO) is a hematopoietic growth factor also displaying neurotrophic properties. Evidence suggests that EPO's neuroprotective action may rely on PI3K/AKT pathway activation; however, data regarding the EPO(More)
To gain a better insight into the neurotoxicity of platinum drugs, it is important to increase our knowledge over the phenomena allowing their entry into dorsal root ganglia neurons. A deeper understanding of platinum-drug transport mechanisms in neurons would represent not only a step forward in the pathogenetic interpretation of their neurotoxicity, but(More)
