Project description:MicroRNAs (miRNAs) are intrinsic regulators in the various cellular processes, and their abnormalities are considered to be involved in the onset of human disorders, including cancer. Circulating miRNA is focused as new cancer biomarker however it is regarded that circulating RNA are released not only from tumor but also by various pathways. Recently, exosomes, small membrane vesicles, have been a major interest in cancer research field, because of their unique biological properties. Exosomes are secreted from various cells and the components (Lipids, mRNAs, miRNAs and proteins) reflect origin of the cells secreting them. Identification of exosomal miRNAs from cancer cells is expected to provide useful biomarkers of cancer. To identify specific exosomal miRNAs as candidate biomarkers for colorectal cancer, we compared exosomal miRNA profiles of 5 colon cancer cell lines with that of normal colon-derived epithelial cells, and isolated a subset of miRNAs as commonly-secreted miRNAs from colon cancer cells Endogenously expression of microRNAs were analyzed by Agilent Human miRNA V3 Microarray (G4470C) using total RNAs of human colon-derived FHC cells and human colon cancer cell lines (HCT116 cells and SW480 cells) at two independent experiments. Exosomal microRNAs were analyzed by microRNA microarray using total RNAs of exosomes from conditioned media of FHC cells, HCT116 cells, and SW480 cells at three independent experiments.As negative control of exosomal microRNAs in conditioned media, FBS-exosomal microRNAs were analyzed at four independent experiments. Exosomes were prepared by step-wise ultra-centrifugation methods. RNA was prepared by Trizol or Trizol-LS reagent (Invitrogen) and RNeasy mini spin column (Qiagen).

To identify specific exosomal miRNAs as candidate biomarkers for colorectal cancer, we profiled exosomal miRNAs in sera of colon cancer patients (n=88) at various TNM stages (I to IV) and healthy controls (n=11) and selected significantly higher microRNAs in serum exosomes of colorectal cancer patients than that of healthy controls. Moreover, we tried to detect their serum exosome levels of using samples from patients after surgical resection of primary tumors (n=24).

Project description:Purpose: Over the past few years, the distinction between left- and right-sided colon cancer has been brought into focus. Right-sided tumor location was associated with an inferior overall survival and progression-free survival. We aimed to perform a detailed analysis of the diversity in exosomes between left- and right-sided colon cancer using quantitative proteomics. Experimental Design: We isolated exosomes from left- and right-sided colon cancer patients and healthy volunteers and treated colorectal cancer cell line with serum-derived exosomes. Then we performed quantitative proteomics analysis of the serum-derived exosomes and cell line treated with exosomes, respectively. Results: The expression profile of the serum exosome proteome in patients with right-sided colon cancer is different from patients with left-sided colon cancer. Serum-derived exosomes of right-sided colon cancer promote metastasis via up-regulation of extracellular matrix-related proteins, especially proteoglycans like SPARC and glycoprotein like LRG1. Exosomal SPARC and LRG1 were closely correlated with progression-free survival. Conclusions: Proteomic analysis identified different exosomal protein profiling between left- and right-sided colon cancer. Serum-derived exosomes of right-sided colon cancer promote metastasis via overexpression of SPARC and LRG1.
