Project description:To find miRNAs that involve in renal epithelial transition and renal fibrosis, we performed unilateral ureteral obstruction of mice for 7 days. After that, we harvested kidneys, and performed microarray of miRNA. Contralateral kidneys without ureteral obstruction were used as controls. miRNAs were purified from kidneys with ureteral obstruction and contralateral kidneys without ureteral obstruction. Then microarray of miRNA was performed (n=4). miRNAs up-regulated in kidneys with ureteral obsctruction compared with contralateral kidneys were sorted. We performed unilateral ureteral obstruction of mice for 7 days, and harvested kidneys.

Project description:miRNAs are involved in stem cell differentiation and we wanted to investigate miRNAs involved in embryonic stem cell differentiation towards renal lineage. Mouse embryonic stem cells were cultured with a renal differentiation medium (suplemented with All-trans-retinoic acid and Activin A) or in a control media, in orther to determine the miRNAs variations between these groups.

Project description:To study the role of miRNAs in the transition from latent to active TB and to discover candidate biomarkers that may help predict TB progression, we have employed miRNA microarray expression profiling as a discovery platform to probe the transcriptome of peripheral blood mononuclear cells (PBMCs) with active TB, latent TB infection (LTBI), and healthy donors.Patients were recruited at the Shanghai Public Health Clinical Centre (Shanghai, China) from December, 2008 to May, 2009. The diagnosis of active TB was based on clinical presentation, chest radiography, and acid-fast stain of sputum smear.All the patients were HIV negative, as diagnosed by the Livzon Anti-HIV1/2 EIA Kit (Livzon Pharmaceutical Group Inc., Guangdong, China). Additional tests were also performed to detect hepatitis B virus (HBV) and hepatitis C virus (HCV) by using the Abbott AxSYM anti-HBsAg and HCV 3.0 antibody assay kit (Abbott Laboratories, Illinois) to exclude HBV- and HCV-positive patients (these 2 diseases are highly prevalent in China). Patients with a diabetes history were also excluded because diabetes could increase the risk of TB. Peripheral venous blood was drawn before treatment. Subjects with LTBI and healthy donors both without a history of clinical TB or other infectious diseases were recruited from the staff at the Shanghai Public Health Clinical Centre. TST and IGRA (T-SPOTM-BM-..TB, Oxford Immunuotec, Oxfordshire, U.K) results were used to distinguish the two groups. The LTBI group was TST-positive (TST>10 mm) and IGRA-positive while the healthy donors were TST-negative (TST<5 mm) and IGRA-negative. RNA of PBMC from 6 patients with active TB, 6 donors with Latent TB, and 3 healthy controls (total of 15 biologically independent samples) were used to perform Agilent Human miRNA (version 3) microarray , No replicates were included

Project description:To better understand the extent to which induced pluripotent stem cells (iPSCs) faithfully recapitulate the characteristics of embryonic stem cells (ESCs) under (undiff)erentiated condition, KSR condition and FBS condition and how both compare to somatic tissues under these conditions, we employed whole-genome transcriptome analysis on all twenty one hESC lines available on the pre-2008 NIH Human Pluripotent Stem Cell Registry, eight human iPSCs derived at NIH by retroviral transduction of human fibroblasts and twenty human somatic tissues. One standard culture protocol was used in conjunction with rigorous quality control. Expanded description of methods used and are available at: http://stemcelldb.nih.gov. 230 samples: 44 human ESC (UNDIFF), 16 human iPSC (UNDIFF) 44 human ESC (KSR), 15 human iPSC (KSR), 44 human ESC (FBS), 15 human iPSC (FBS), 1 human Brain, 1 human Placenta, 1 human Skeletal Muscle, 1 human Heart, 1 human Liver, 1 human Lung, 1 human Kidney, 1 human Esophagus, 1 human Ovary, 1 human Testes, 1 human Spleen, 1 human Adipose, 1 human Thyroid, 1 human Thymus, 1 human Small Intestine, 1 human Prostate, 1 human Cervix, 1 human Colon, 1 human Bladder, 1 human Trachea) and 32 processing controls (UniRef).

Project description:Background: Osteosarcomas are the most common primary malignant tumors of bone and show multiple and complex genomic aberrations. miRNAs are non-coding RNAs capable of regulating gene expression at the post transcriptional level, and miRNAs and their target genes may represent novel therapeutic targets or biomarkers for osteosarcoma. In order to investigate the involvement of miRNAs in osteosarcoma development, global microarray analyses of a panel of 19 human osteosarcoma cell lines was performed. Principal findings: We identified 177 miRNAs that were differentially expressed in osteosarcoma cell lines relative to normal bone. Among these, miR-126/miR-126*, miR-142-3p, miR-150, miR-223, miR-486-5p and members of the miR-1/miR-133a, miR-144/miR-451, miR-195/miR-497, and miR-206/miR-133b clusters were found to be downregulated in osteosarcoma cell lines. All miRNAs in the paralogous clusters miR-17-92, miR-106b-25 and miR-106a-92 were overexpressed. Furthermore, the upregulated miRNAs included miR-9/miR-9*, miR-21*, miR-31/miR-31*, miR-196a/miR-196b, miR-374a and members of the miR-29, miR-130/301 families. The most interesting inversely correlated miRNA/mRNA pairs in osteosarcoma cell lines included miR-9/TGFBR2 and miR-29/the p85α regulatory subunit of PI3K. PTEN mRNA correlated inversely with miR-92a and members of the miR-17 and miR-130/301 families. Expression profiles of selected miRNAs were confirmed in clinical samples. A set of miRNAs, miR-1, miR-18a, miR-18b, miR-19b, miR-31, miR-126, miR-142-3p, miR-133b, miR-144, miR-195, miR-223, miR-451 and miR-497 was identified with an intermediate expression level in osteosarcoma clinical samples compared to osteoblasts and bone, which may reflect the differentiation level of osteosarcoma relative to the undifferentiated osteoblast and fully differentiated normal bone. Significance: This study provides an integrated analysis of miRNA and mRNA in osteosarcoma, and gives new insight into the complex genetic mechanisms of osteosarcoma development and progression. 19 osteosarcoma cell lines, 4 normal bones used as controls. No replicates. The group of osteosarcomas are compared to the group of normal bones.
