Project description:An evaluation of biopsies from patients with in-transit extremity melanoma who have been treated with ADH-1 followed by melphalan in the setting of isolated limb infusion Gene expression profiles were obtained from 28 lesions across 15 patients and evaluated for expression values that correlated with ADH-1 treatment given 4-8hrs prior to melphalan isolated limb infusion Chemotherapy response analysis: complete response - CR; partial response - PR; stable disease - SD; progressive disease - PD; lost to follow-up - LTU/F ADH-1 treatment classification: 'pre' - lesions obtained prior to any treatment with ADH-1; 'post' - lesions obtained just prior to ILI with melphalan after 1 treatment with ADH-1; '2nd' - lesions obtained after a 2nd dose of ADH-1 given 8 days after melphalan ILI

Project description:To identify patterns of change in gene expression that correlated with drug treatment (saline control, ADH-1 alone, melphalan alone and ADH-1 plus melphalan) in our animal model of regional therapy for extremity melanoma we evaluated gene expression using microarray genechips and a Pearson correlation analysis. Genes were ranked according to the degree to which expression correlated with systemic ADH-1 treatment alone or in combination with regional melphalan. Tissue samples were harvested at 4, 24 and 48 hours after treatment with melphalan. Specific cellular pathways associated with drug treatment were identified using gene set enrichment analysis (GSEA). Experiment Overall Design: Sample size was 2 rats for each drug treatment group at both the 4 and 24 hour time points. At the 48 hour time point sample size was 1 rat for each drug treatment group. ADH-1 treatment preceded melphalan by 1 hour. ADH-1 treatment was repeated at 24 and 48 hrs. Tissue was harvested for RNA analysis at 4, 24 and 48 hours after completion of isolated limb infusion with melphalan (and 1 hour after an ADH-1 dose).

Project description:Cutaneous melanomas are malignant radio and chemoresistant neoplasias presenting high morbidity and elevated mortality rates. Isolated Limb Perfusion (ILP) with Melphalan (Mel) is used in the treatment of non-resectable locally advanced melanomas of extremity sparing the limb from amputation in 40-50% of the cases. Adding the Tumor Necrosis Factor alpha (Tnfa) improves total complete response to 70-90%. The cellular and molecular mechanisms underlying the changes promoted by Mel and Tnfa are not completely understood. In this study we evaluated the impact of systemic Mel and Tnfa administration on tumor growth, analyzed the morphological changes promoted by each treatment, and searched for early molecular targets of Mel and Tnfa, alone or in combination, in a murine melanoma model. Morphological changes were analyzed by histological analysis, while microarray gene expression followed by quantitative RT-PCR were used to search for early molecular targets. We found that Mel systemic administration accounted for the impairment of tumor-growth (p<0.001) and improvement of survival. Tnfa co-administration augmented necrosis (p<0.024) and decreased mitotic rates (p=0.001). We identified a set of 118 potential molecular markers that might be correlated with the observed biologic response to treatment with Melphalan and Tnfa and which could represent potential therapeutic targets in melanoma.

Project description:An evaluation of multifocal lesions from patients with in-transit extremity melanoma to determine if all lesions from a patient harbor homogeneous patterns of gene expression Gene expression profiling studies can help guide treatment for cancer patients by providing tools in the form of gene-expression signatures to characterize a tumor in terms of underlying biology, predicted response to therapy, metastatic progression and/or recurrence. The utility of gene signatures for defining therapeutic strategies in the treatment of extremity in-transit melanoma will be dependent on the genetic relationship between the multifocal lesions typically present in this disease and the extent to which a single lesion is representative of residual tumor burden. Using microarray-based gene expression profiling we examined 43 in-transit melanoma lesions across 17 patients with multifocal disease to determine whether one lesion could accurately characterize the underlying biology and genetic profile of a patient's tumor. Principal component analysis, unsupervised hierarchical clustering, one-way analysis of variance (ANOVA) and gene signatures predictive of chemosensitivity and oncogenic pathway activation showed gene expression patterns to be highly similar (p-values: <0.006; average r = 0.979) between lesions from a single patient but to be significantly different across patients (p<0.05). These findings demonstrate that individual melanoma tumor nodules in patients with multifocal disease are genetically similar and a single lesion can be used to predict response to chemotherapy, evaluate the activation status of oncogenic signaling pathways and characterize other aspects of the biology of an individual patient's disease. These results will facilitate the utilization of gene expression profiling in clinical trials of targeted therapy in melanoma allowing for more rational identification of candidates for specific therapies.

Project description:Autologous peripheral hematopoietic stem cell transplantation (autoHSCT) is one front-line therapy with high-dose melphalan for multiple myeloma (MM). Patients with MM who receive conditioning regimen with melphalan usually suffer from severe gastrointestinal symptoms, as one of nonhematological toxicities. Aim: It is an urgent demand to develop an effective methods to repair the intestinal injuries in patients with MM receiving conditioning regimen with high-dose melphalan for autoHSCT. Therefore, the protective effects of Human umbilical cord derived-mesenchymal stem cells (hucMSCs) is investigated after infusion into mouse model with melphalan-induce gastrointestinal injuries.
