Project description:We collected ovarian follicle fluids from 68 patients and assigned them to good group or bad group according to their oocyte quality. The exosomes were isolated and characterized. Exosomal microRNAs were extracted, the library was constructed and sequenced by Illumina hiseq platform. The exosomal microRNA expression was analyzed and profiled, the target genes were predicted, GO terms were enriched by GOSeq and KEGG pathway was analyzed using miranda.A total of 47 differential microRNAs was expressed significantly between good and bad group, of which 9 microRNAs were known microRNAs and 7 of them was upregulated in the bad group. In-silico analysis indicated that several of these exosomal microRNAs were involved in pathways implicated in oocyte quality.Our study suggests that exosomal microRNAs in ovarian follicle fluid are critical in maintaining the oocyte quality. Our study greatly improve our understanding of exosomal microRNAs in human ovarian follicular fluid, paving the way for further investigation on the microRNA functions in the ovarian microenvironment and the mechanism behind it.

Project description:To check the profile of exosomal and cellular miRNA in ovarian cancer cell lines, total RNA were extracted from exosomes and cells. Thirteen ovarian cancer cell lines (A2780, ES-2, CAOV3, SKOV3, OV-90, OAW42, MCAS, COV362, RMG-1, RMUG-S, KURAMOCHI, NIH-OVCAR3 and A2780cis) were investigated, and HOSE1, HOSE2 and HOSE3 (human ovarian surface epithelim cell lines) were used as control.

Project description:In an attempt to clarify the diferrence of exosomal microRNA derived from Normal BM and primary AML CD34+ cells. Primary cells were cultured in serum free medium and supernatant was harvested. After extract microRNAs, the difference of exosomal microRNAs between normal BM and leukemia was analyzed by array.

Project description:Extracellular microRNA sequences have attracted interest for their potential use as accessible biomarkers that may be non-invasively collected from a wide range of biological fluids, including spent culture media. The ongoing milieu between the late-stage preimplantation embryo and the receptive uterus remains an actively investigated area of research and the physiological role of secreted microRNA sequences remains to be determined. Spent culture media used to culture late stage E4.0 murine blastocysts was screened for 641 mature microRNA sequences using a qPCR-based array. We report here the 39 sequences that were exclusively detected in the conditioned media using this approach. The embryonic miR-290 family were among the most abundant extracellular sequences. Notably, implantation-relevant members miR-126a, miR-101a, miR-143 and miR-320 were also detected.

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).
