Project description:The purpose of this experiment is to detect and characterize circulating tumor cells in single cell sequence data and characterize the other cell types in the blood.
Project description:We analyzed the proteome of tumor and matched non-tumor biopsies from 51 treatment-naive Hepatocellular carcinoma (HCC) patients by DIA (SWATH). Thereby we aim to find subgroups of patients characterized by specific pathway activation. Furthermore, we aim to find novel factors involved in HCC development and novel biomarkers.
Project description:Circulating Tumor Cells (CTCs) are shed from primary tumors into the bloodstream, mediating the hematogenous spread of cancer to distant organs. Using a pancreatic cancer mouse model, we applied a microfluidic device to isolate CTCs independently of tumor epitopes, subjecting these to single cell RNA-sequencing. This study was conducted to determine the heterogeneity of pancreatic CTCs and to compare these CTCs to matched primary tumors, cell line controls (NB508 cancer cell line and MEF non-cancer cell line), primary tumor single cells, and normal leukocytes/WBCs. We profiled RNA from 75 single cells circulating in mouse blood enriched for circulating tumor cells from 5 mice, 12 single cells from a mouse embryonic fibroblast cell line, 16 single cells from the nb508 mouse pancreatic cancer cell line, 12 single mouse white blood cells, 18 single GFP lineage-traced circulating tumor cells from two mice, 20 single GFP lineage-traced cancer cells from the primary pancreatic tumor of a mouse, and 34 dilutions to 10 or 100 picograms of total RNA from mouse primary pancreatic tumors from 4 mice.
Project description:We analyzed the phospho-proteome of tumor and matched non-tumor biopsies from 51 treatment-naive Hepatocellular carcinoma (HCC) patients by label-free DDA. Thereby we aim to find subgroups of patients characterized by specific pathway activation. Furthermore, we aim to find novel factors involved in HCC development and novel biomarkers.
Project description:The dismal outcome of hepatocellular carcinoma (HCC) is closely associated with intra- and extrahepatic metastases, which have been proposed to be initiated by circulating tumor cells (CTCs). However, the plasticity of gene expression and immune evasion mechanisms of CTCs during systemic circulation are not well defined. Here, we determined intra- and inter-vascular transcriptional heterogeneity within the circulatory system using single-cell RNA-sequencing of 113 CTCs isolated from four key vascular sites along their dissemination route in ten HCC patients.
Project description:Tumor samples and matching healthy tissue from 23 human hepatocellular carcinoma (HCC) patients and one hepatocellular adenoma patient were collected after surgical resection. Total RNA was harvested and sequenced with a strand-specific single-end RNA-seq protocol.
Project description:The purpose of the study is to detect somatic mutations in hepatocellular carcinoma using circulating free-DNA. We used deep-sequencing data of a panel of 60 commonly mutated genes in hepatocellular carcinoma.
Project description:We employed marker-free single-cell RNA-Seq to characterize comprehensive transcriptional profiles of 3200 single cells from 4 human hepatocellular carcinoma (HCC) specimens.
