Project description:MicroRNAs (miRNAs) are noncoding RNAs of approximately 22 nucleotides in length that usually suppress the translation of target messenger RNAs (mRNAs) through partial complementarity to the 3¡¦ untranslated region (3¡¦ UTR) of protein-coding mRNAs in animals. However, there is increasing evidence that miRNAs can also reduce the steady-state levels of their target mRNAs in animals. In this investigation, both miRNA and mRNA profiles from the undifferentiated human embryonic stem cell line hES-T3 (T3ES), hES-T3 derived embryoid bodies (T3EB) and hES-T3 differentiated fibroblast-like cells (T3DF) were quantitatively determined. Three common target genes of three highly expressed hES cell-specific miRNAs were identified by inverse expression levels of miRNAs to their target mRNAs. Experiment Overall Design: Three types of human embryonic stem cells and their derived cells (the undifferentiated human embryonic stem cell line hES-T3 (T3ES), hES-T3 derived embryoid bodies (T3EB) and hES-T3 differentiated fibroblast-like cells (T3DF)) were selected for RNA extraction. The genome-wide mRNA expression of T3ES, T3EB and T3DF cells was determined using Affymetrix human genome U133 plus 2.0 GeneChip. The abundantly expressed genes (10-fold above overall mean) in T3ES, T3EB and T3DF cells are selected to compare with the predicted gene targets of differentially expressed miRNAs in the same set of cells.

Project description:Type 1 diabetes is an autoimmune destruction of pancreatic islet beta cell disease, and it is important to find new alternative source of the islet beta cells to replace the damaged cells. Human embryonic stem (hES) cells possess unlimited self-renewal and pluripotency and thus have the potential to provide an unlimited supply of different cell types for tissue replacement. The hES-T3 cells with normal female karyotype were first differentiated into embryoid bodies and then induced to generate the pancreatic islet-like cell clusters, which expressed pancreatic islet cell-specific markers of insulin, glucagon and somatostatin. The expression profiles of microRNAs and mRNAs from the pancreatic islet-like cell clusters were further analyzed and compared with those of undifferentiated hES-T3 cells and differentiated embryoid bodies. MicroRNAs negatively regulate the expression of protein-coding mRNAs. The pancreatic islet-like cell clusters were found to exhibit very high expression of microRNAs miR-186, miR-199a and miR-339, which down-regulated the expression of LIN28, PRDM1, CALB1, GCNT2, RBM47, PLEKHH1, RBPMS2 and PAK6. Therefore, these microRNAs are very likely to play important regulatory roles in the differentiation of pancreatic islet cells and early embryonic development. In this investigation, both miRNA and mRNA expression profiles from the pancreatic islet-like cell clusters differentiated from hES-T3 cells (T3pi) were quantitatively determined and compared with those of undifferentiated hES-T3 cells grown on mouse embryonic fibroblast (MEF) feeder (T3ES) and embryoid bodies differentiated from hES-T3 cells (T3EB). Several target genes of pancreatic islet cell-specific miRNAs were identified. ***This submission represents the mRNA expression component of the study only***

Project description:Background: The hES-T3 cell line with normal female karyotype was used to differentiate into autogeneic fibroblast-like cells (T3HDF) as feeder to support the undifferentiated growth of hES-T3 cells (T3/HDF) for 14 passages. A feeder-free culture on Matrigel in hES medium conditioned by these autogeneic feeder cells (T3HDF) was established to maintain the undifferentiated growth of hES-T3 cells (T3/CMHDF) for 8 passages. Results: The gene expression profiles of mRNAs, microRNAs and proteins between the undifferentiated T3/HDF and T3/CMHDF cells were shown to be very similar, and their expression profiles were also found to be similar to those of T3/MEF and T3/CMMEF cells grown on MEF feeder and feeder-free Matrigel in MEF-conditioned medium, respectively. The abundantly expressed genes of T3/HDF, T3/CMHDF, T3/MEF and T3/CMMEF cells were found to play prominent roles in signaling pathways and GO process networks. The miR-302/367 cluster and miR-371/372/373 cluster were extremely abundantly expressed in undifferentiated T3/HDF and T3/CMHDF as well as T3/MEF andT3/CMMEF cells. The undifferentiated state of T3/HDF and T3/CMHDF cells was evidenced by the very high expression levels of ¡§stemness¡¨ genes and low expression levels of differentiation markers of ectoderm, mesoderm and endoderm in addition to the strong staining of OCT4 and NANOG. Conclusion: The T3HDF feeder and T3HDF-conditioned medium were able to support the undifferentiated growth of hES cells, and they would be useful for drug development and toxicity testing in addition to the reduced risks of xenogeneic pathogens when used for medical applications such as cell therapies.

Project description:Human embryonic stem (hES) cells have the capacities to propagate for extended periods and to differentiate into cell types from all three germ layers both in vitro and in vivo. These characteristics of self-renewal and pluripotency enable hES cells having the potential to provide an unlimited supply of different cell types for tissue replacement, drug screening, and functional genomics studies. The hES-T3 cells with normal female karyotype cultured on either mouse embryonic fibroblasts (MEF) in hES medium (containing 4 ng/ml bFGF) (T3MF) or feeder-free Matrigel in MEF-conditioned medium (supplemented with additional 4 ng/ml bFGF) (T3CM) were found to express very similar profiles of mRNAs and microRNAs, indicating that the unlimited self-renewal and pluripotency of hES cells can be maintained by continuing culture on these two conditions. However, the expression profiles, especially microRNAs, of the hES-T3 cells cultured on Matrigel in hES medium supplemented with 4 ng/ml bFGF and 5 ng/ml activin A (T3BA) were found to be different from those of T3MF and T3CM cells. In T3BA cells, four hES cell-specific microRNAs miR-372, miR-302d, miR-367 and miR-200c, as well as three other microRNAs miR-199a, miR-19a and miR-217, were found to be up-regulated, whereas five miRNAs miR-19b, miR-221, miR-222, let-7b and let-7c were down-regulated by activin A. Thirteen abundantly differentially expressed mRNAs, including NR4A2, ERBB4, CXCR4, PCDH9, TMEFF2, CD24 and COX6A1 genes, targeted by seven over-expressed miRNAs were identified by inverse expression levels of these seven microRNAs to their target mRNAs in T3BA and T3CM cells. The NR4A2, ERBB4 and CXCR4 target genes were further found to be regulated by EGF and/or TNF. The 50 abundantly differentially expressed genes targeted by five under-expressed miRNAs were also identified. The abundantly expressed mRNAs in T3BA and T3CM cells were also analyzed for the network and signaling pathways, and roles of activin A in cell proliferation and differentiation were found. These findings will help elucidate the complex signaling network which maintains the self-renewal and pluripotency of hES cells.

Project description:We show that target mRNAs trigger the non-templated addition of nucleotides (mainly adenosines and uridines) and shortening of their cognate miRNAs in primary hippocampal neurons. The induced effect is observable both in total RNA and in Ago2-associated RNA, demonstrating that the process is initiated in Ago2 bound miRNAs. Illumina Small RNA sequencing was performed on rat hippocampal neurons infected with different target mRNAs in different conditions. The data includes 3 independent experiments: 1. Hippocampal neurons (DIV15) 6 days after transducing them with target mRNAs (driven by the Synapsin promoter) against different miRNAs. Samples are titled "Syn-Target". Samples transduced with targets containing extensive complementarity are labeled "Ext" and those with Seed complementarity are labeled "Seed". 2. Hippocampal neurons (DIV16) 7 days after transducing them with an inducible target mRNA against miR-132, and inducing for different times with Doxycycline. Samples are titled "Time-course" 3. Hippocampal neurons (DIV16) 7 days after co-transducing them with FLAG/HA-Ago2 plus an inducible target mRNA against miR-132, and inducing them for different times with Doxycycline. Samples are titled "Time-course_Ago2"

Project description:MicroRNAs (miRNA), discovered in C. elegans, are short non-coding RNAs that bind and regulate the expression of target mRNAs in animals and plants. C. elegans miRNAs bind to partially complementary sequences in the 3' UTR of the target mRNA, which results in translational repression through mRNA destabilization. The high-throughput sequencing of RNA cleavage fragments was performed to directly detect cleaved miRNA targets in C. elegans. Based on this analysis, miR-249 was identified as a potential miRNA that regulates a ZK637.6 pseudogene, paralogous to asna-1 (ZK637.5), by a cleavage mechanism with extensive, evolutionary conserved complementarity. Additionally, we validated miR-249-directed cleavage of the ZK637.6 by a gene-specific 5M-bM-^@M-^Y rapid amplification of cDNA ends and observed notable difference in expression of ZK637.6 in wild-type versus mir-249 mutant C. elegans. Furthermore, phosphate-independent small-RNA sequencing analysis revealed that miR-249 target genes, including ZK637.6 pseudogene, showed 22G-RNA productions dependent on miR-249 targeting. These findings may lead to a better understanding of the biological roles of miRNAs for pseudogenes in C. elegans. Total small RNAs from wild-type and mir-249 mutant in adult stage worms were subjected to small RNA sequencing using an Illumina platform with Tobacco Acid Pyrophosphatase (TAP) treatment, allowing detection of secondary siRNAs carrying 5M-bM-^@M-^Y-tri-phosphate.
