Project description:Multiple myeloma (MM) is a hematopoietic malignancy. Based on its laboratory and clinical presentation, it can be categorized as MGUS, smoldering myeloma, and multiple myeloma. Previous studies have indicated that the expression levels of miRNAs differ across various stages of the disease, and exosomes are involved in modulating the progression and metastasis of cancers through miRNAs. This study aims to analyze the expression levels of miRNAs in the serum exosomes of healthy individuals and those with myeloma bone marrow.

Project description:Multiple myeloma is a multi-stage disease. Based on its laboratory and clinical presentation it can be summarized as MGUS, smoldering myeloma, and multiple myeloma. Previous studies have shown that the expression levels of miRNAs in different stages of the disease are different. This study analyzes the expression levels of miRNAs in healthy individuals and myeloma serum exosomes. We used microarrays to detail the miRNAs expressionin between 12 healthy individuals and 12 multiple myeloma and identified distinct classes of dys-regulated genes.

Project description:Bone marrow stromal cells (BMSCs) and their exosomes are a promising area of cancer therapy. Multiple myeloma (MM) is refractory hematologic malignancy. Bone marrow stromal cells (BMSCs) interact with MM cells in the bone marrow (BM), and also create a permissive microenvironment for MM cell growth and survival. Recent evidence indicated that exosome-mediated MM cell-BMSC communication plays an important role in the MM microenvironment. In this study, we investigated the biological property of the exosomes and exosomal miRNAs derived from BMSCs, aiming to establish the emerging strategies to target MM microenvironment to prevent tumor growth and spread.

Project description:The aim of this study was to identify and evaluate exosomal miRNAs in serum as early diagnostic markers for gastric cancer (GC). Methods: Using next-generation sequencing (NGS) and bioinformatics, we identified candidate serum exosomal miRNA markers for early detection of GC in patients. The candidates were further validated by qRT-PCR in 50 newly recruited early-stage GC patients and matched healthy individuals. Results: NGS revealed that the average mappable reads in the RNA libraries were about 6.5 million per patient. A total of 66 up and 13 down-regulated exosomal miRNAs were found in the screened cohort after removal of log2 transformed read counts <5 and p >0.05. In the validation cohort, by comparing candidate exosomal miRNAs levels in early-stage GC patients and healthy individuals, higher levels of miR-92b-3p, let-7g-5p, miR-146b-5p and miR-9-5p were found to be significantly associated with GC. Diagnostic power of the combined panels of the exosomal miRNAs or the combination of exosomal miRNAs and CEA outperformed that of single exosomal miRNA marker for establishing a diagnosis of early-stage GC. In addition, serum levels of exosomal miR-92b-3p were significantly associated with low adhesion, let-7g-5p and miR-146b-5p were significantly correlated with nerve infiltration, and miR146b-5p was statistically correlated with tumor invasion depth in early-stage GC. Conclusions: Serum exosomal miR-92b-3p, -146b-5p, -9-5p, and let-7g-5p may serve as potential noninvasive biomarkers for early diagnosis of GC. Further validation of these candidate exosomal miRNAs in larger experimental cohorts are required in order to confirm the diagnostic values.

Project description:In multiple myeloma (MM), abnormal plasma cells interact with bone marrow (BM) stromal cells and vascular cells among others. A part of the BM milieu is considered highly hypoxic, and myeloma cells in situ may be influenced by circumstances other than normoxia in vitro. Hence, we attempted to confirm the role of hypoxic MM-derived exosomes in the BM milieu. We established a novel hypoxia-resistant cell line, U266HR, derived from U266 cells cultured for >4 months under hypoxia (1% O2), as a model of MM cells localizing in an extensively hypoxic milieu. We used U266 cells and U266HR cells, as donor cells, and HUVECs as recipient cells. Exosomes derived from U266 cells (normoxia or hypoxia) and exosomes derived from U266HR cells (hypoxia-resistant sub-line) were used for validation of angiogeneic activity, such as tube formation assay. Exosomes derived from the U266HR cells significantly increased tube formation of HUVECs than those from U266 cells. To identify intercellular and exosomal miRNAs specifically expressed in hypoxia-resistant cells, we assess the expression profiles of intercellular and extracellular miRNAs in U266 cells and U266HR cells using Taqman MicroRNA Array v2.0 (Applied Biosystems, Bedford, MA). U266 cells were cultured for 24 hours under hypoxic conditions (1% O2) or normoxic conditions (20% O2). The exosome fraction was obtained from culture medium using Exoquick Exosome Precipitation Solution (System Biosciences, Mountain View, CA, USA). Isolation of cellular and exosomal miRNAs was performed using the miRNsasy kit (Qiagen). The expression profile of miRNAs was determined using the Human Taqman miRNA Arrays A (Applied Biosystems). RNU6B and a spike control (ath-miR159) were used as an invariant control for the cell and exosome, respectively. QRT-PCR was carried out on an Applied Biosystems 7900HT thermal cycler using the manufacturerM-bM-^@M-^Ys recommended program. Finally, all the raw data from each array was run on Data Assist Software ver.3.1 (Applied Biosystems).
