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 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). Serum exosomes were prepared by step-wise ultra-centrifugation methods in 11 healthy controls and 88 colorectal cancer patients with various TNM stages (I; n=20, stage II; n=20, stage IIIa; n=20, stage IIIb: n=16, stage IV; n=12) (age; 35-65) .Exosome fraction was mixed with Trizol-LS reagent (Invitrogen), and aqueous phase was collected by adding chloroform. After addition of ethanol to the aqueous phase, it was placed on to an RNeasy mini spin column (Qiagen) for the purification of total RNAs. The total RNAs were analyzed by Agilent Human miRNA V3 Microarray (G4470C) according to the manufacturer's instructions.

Moreover, we tried to detect their serum exosome levels of using samples from patients after surgical resection of primary tumors (n=24). Serum exosomes were prepared by step-wise ultra-centrifugation methods in 24 colorectal cancer patients (age; 35-65) after surgical resection of primary tumor (TNM stage I; n=6, stage II; n=5, stage IIIa; n=5, stage IIIb; n=5, stage IV; n=3) .Exosome fraction was mixed with Trizol-LS reagent (Invitrogen), and aqueous phase was collected by adding chloroform.

Project description:Pancreatic cancer has a dismal prognosis partly due to late diagnosis, where a reliable non-invasive diagnosis is urgently wanted. We here explored, whether serum-derived PaCa exosomes may provide a diagnostic means and microRNA may be advantageous. Exosomes were collected from the serum of 133 patients with pancreatic cancer, 22 patients with non-malignant pancreatic tumors, 25 patients with chronic pancreatitis and 20 healthy donors. Exosomes were isolated by ultracentrifugation and used qRT-PCR for miRNA quantification and miRCURY LNA microRNA Array for miRNA analysis.
