Single cell RNA-seq profiling of patient-derived Merkel cell carcinoma tumor samples

Project description:Merkel cell carcinoma (MCC), a rare but aggressive neuroendocrine cancer of the skin, remains a challenge in the era of precision medicine. MCC tumor heterogeneity has been attributed to the variant disease etiologies, mediated by either UV exposure or Merkel cell polyomavirus (MCPyV). However, over the years it has become clear that these two groups are largely similar in clinical presentation, prognosis, and treatment response to immune-checkpoint inhibitors. We therefore dissected the transcriptomic heterogeneity of a panel of patient tumors samples, at the single-cell resolution, to gather further insights.

Comparative Transcriptional Profiling of human Merkel cells and Merkel Cell Carcinoma

Project description:Merkel cell carcinoma is supposed to be derived from Merkel cells after infection by Merkel cell polyomavirus (MCV) and other poorly known events. A transcriptional profiling with cDNA microarrays was performed on cells from MCV+ Merkel cell carcinomas and isolated normal Merkel cells. This microarray revealed numerous significantly upregulated genes and down-regulated genes. The extensive list of genes identified in these experiments provides a large body of potentially valuable information of Merkel cell carcinoma carcinogenesis and could represent a source of potential targets for cancer therapy. Two-conditions experiment, MCV vs Normal Merkel Cell. Biological replicates : 4 MCV (Cy5), 1 control = pool of Normal Merkel cells from 3 liftings

microRNA expression patterns related to merkel cell polyomavirus infection and clinical outcomes in human merkel cell carcinoma

Project description:We performed miRNA expression profiling in a series of human Merkel Cell carcinoma samples using a microarray approach. Significant differentially expressed miRNAs among groups were identified using SAM analysis. Agilent microarray platform containing 723 human miRNAs was used to determine miRNA expression profiles in 16 human Merkel cell carcinoma (MCC) samples. To validate the microarray platform, the expression levels of selected miRNAs were evaluated using qRT-PCR.

scRNAseq reveals mechanisms of Merkel cell carcinoma acquired immunotherapy resistance [1]

Project description:Serial blood draws from a single patient and serial tumor biopsies from the same patient with metastatic Merkel cell polyomavirus Merkel cell carcinoma, who was treated with cellular immunotherapy targeting MCPyV (autologous endogenous T cell therapy) followed by checkpoint inhibitors (anti-PD1 and anti-CTLA4). The patient had a 22 month clinical response followed by late/acquired resistance. We performed scRNAseq using the 10x genomics 3' Chromium expression assay to determine potential mechanisms contributing to immunotherapy response and late resistance

Characterization of the Merkel cell carcinoma miRNome

Project description:MicroRNAs have been implicated in various skin cancers, including melanoma, squamous cell carcinoma, and basal cell carcinoma; however, the expression of microRNAs and their role in Merkel cell carcinoma (MCC) have yet to be explored in depth. To identify microRNAs specific to MCC (MCC-miRs), next-generation sequencing (NGS) of small RNA libraries was performed on different tissue samples including MCCs, other cutaneous tumors, and normal skin. Comparison of the profiles identified several microRNAs upregulated and downregulated in MCC. For validation, their expression was measured via qRT-PCR in a larger group of MCC and in a comparison group of non-MCC cutaneous tumors and normal skin. Eight microRNAs were upregulated in MCC: miR-502-3p, miR-9, miR-7, miR-340, miR-182, miR-190b, miR-873, and miR-183. Three microRNAs were downregulated: miR-3170, miR-125b, and miR-374c. Many of these MCC-miRs, with the miR-183/182/96a cistron in particular, have connections to tumorigenic pathways implicated in MCC pathogenesis. In situ hybridization confirmed that the highly expressed MCC-miR, miR-182, is localized within tumor cells. Furthermore, NGS and qRT-PCR reveals that several of these MCC-miRs are highly expressed in the patient-derived MCC cell line, MS-1. These data indicate that we have identified a set of MCC-miRs with high implications for MCC research.

Comparative genomic hybridization of human Merkel cell carcinoma tumors

Project description:Array-CGH profiles of Merkel cell carcinoma tumors Experiment Overall Design: We perfromed array-CGH on 25 Merkel cell carcinoma tumor samples (2 primary/metastasis pairs) looking for recurrent gains/losses among the cohort of tumors. Experiment Overall Design: Results from the Analysis of Copy Errors (ACE) may be found in GSE13239_MccACEAnalyzedData.txt. Experiment Overall Design: The overall profiles of the primary/metastasis pairs are similar. These metastases samples, 1m and 3m, were excluded from the ACE analysis.
