(Submitter supplied) To identify the miRNAs which play a role in the development of endometriosis, we explored differentially expressed miRNAs between ECSCs (N=8) and normal endometrial stromal cells (NESCs, n=8) using miRNA microarray. The expression profiles in ECSCs and NESCs were obtained, then the miRNAs were filtered by signal intensity (20.0<, at least one out of 16 samples have values within range) and flags (at least 70% of cases have good flags). more...

(Submitter supplied) Twenty-four triple-negative breast cancer and 14 adjacent normal tissues were collected from breast cancer patients during surgeries at National Taiwan University Hospital (NTUH, Taipei, Taiwan). All triple-negative breast cancer samples were invasive ductal carcinomas (IDC) and were negative in immunohistochemical statuses of ER, PR, and HER2 receptors, as confirmed by professional pathologists. Treatment procedure of all patients followed the National Comprehensive Cancer Network (NCCN) guideline. more...

(Submitter supplied) We evaluated the expression profile of miRNA and snoRNA of normal mucosa in five patients with synchronous CRCs and seven patients with solitary CRCs using the Affymetrix GeneChip miRNA 1.0 array. We found that global dysregulated miRNAs and snoRNAs in normal mucosa between solitary and synchronous CRC. Our findings represent the first comprehensive miRNA and snoRNA expression signatures in normal mucosa between solitary and synchronous CRC, which increases the understanding of the molecular basis of synchronous CRC, and firstly implicates the difference of genetic background in patients with solitary and synchronous CRC.

(Submitter supplied) We evaluated the profile of miRNA and snoRNA expression in 5 synchronous CRC and matched normal colorectal tissues using the Affymetrix GeneChip miRNA 1.0 array. A total of 24 miRNA differential expressed transcripts which represent 27 mature miRNAs, including an oncogenic miR-17-92a and oncosuppressive miR-143-145 cluster, and a global up-regulation of snoRNAs were revealed in cancer tissues compared with matched normal tissues. more...

(Submitter supplied) Metastasis is a complex process involving multiple steps. We were interested in the role of microRNAs (miRNAs) in the process of liver colonization by colorectal cancer cells. We hypothesized that the comparison between non-metastatic versus metastatic isogenic cell line should thus offer valuable insight to the molecular mechanisms involved in developing metastatic behavior. KM12C/KM12SM and SW480/SW620 are probably the best available models of isogenic cell lines differing in metastatic properties for colorectal cancer. more...

(Submitter supplied) Abstract: Altered expression of microRNAs (miRNAs) is associated with development and progression of various human cancers by regulating the translation of oncogenes and tumor suppressor genes. In colorectal cancer (CRC), these regulators complement the Vogelstein multi-step model of pathogenesis and have the potential of becoming a novel class of tumor biomarkers and therapeutic targets. Using QRT-PCR, we measured the expression of 621 mature miRNAs in 40 CRCs and their paired normal tissues and identified 23 significantly deregulated miRNAs. more...

(Submitter supplied) MicroRNAs (miRNAs) contribute to chronic kidney disease progression via negatively regulating mRNA abundance. However, their association with clinical outcome remains poorly understood. We performed large-scale miRNA and mRNA expression profiling on cryo-cut renal biopsy sections from a discovery (n=43) and a validation (n=29) cohort. In the discovery cohort (GEO Series accession number GSE45980), miRNAs differentiating stable and progressive cases were determined, and putative target mRNAs showing inversely correlated expression profiles were identified. more...

(Submitter supplied) Cancer-associated fibroblasts (CAFs) promote tumor progression through several mechanisms. MicroRNAs (miRNAs) play a key role in CAFs tumor-promoting properties, however, their role in CAFs from different topological areas in lung cancer progression remains unclear. This study aimed to characterize the miRNA expression profile of fibroblasts isolated from matched tumor front (F-CAFs), inner tumor (In-CAFs), and normal adjacent tissue (NFs) in lung adenocarcinoma, using microarray analysis and RT-qPCR. more...

(Submitter supplied) BACKGROUND: Orofacial development is a multifaceted process involving precise, spatio-temporal expression of a panoply of genes. MicroRNAs (miRNAs) constitute the largest family of noncoding RNAs involved in gene silencing, and represent critical regulators of cell and tissue differentiation. MicroRNA gene expression profiling is an effective means of acquiring novel and valuable information regarding the expression and regulation of genes, under the control of miRNA, involved in mammalian orofacial development. more...
