(Submitter supplied) The molecular events during nongenotoxic carcinogenesis and their temporal order are poorly understood but thought to include long-lasting perturbations of gene expression. Here, we have investigated the temporal sequence of molecular and pathological perturbations at early stages of phenobarbital (PB) mediated liver tumor promotion in vivo. Molecular profiling (mRNA, microRNA [miRNA], DNA methylation, and proteins) of mouse liver during 13 weeks of PB treatment revealed progressive increases in hepatic expression of long noncoding RNAs and miRNAs originating from the Dlk1-Dio3 imprinted gene cluster, a locus that has recently been associated with stem cell pluripotency in mice and various neoplasms in humans. more...

(Submitter supplied) Pluripotent stem cells are increasingly used for therapeutic models, including transplantation of neural progenitors derived from human embryonic stem cells (hESCs). Recently, long non-coding RNAs (lncRNAs), including Maternally Expressed Gene 3 (MEG3) that is derived from DLK1-DIO3 imprinted locus, were found to be expressed during neural developmental events. Their deregulations are associated with various neurological diseases. more...

(Submitter supplied) Parental imprinting is a form of epigenetic regulation that results in parent-of-origin differential gene expression. To study Prader-Willi syndrome (PWS), a developmental imprinting disorder, we generated patient-derived induced pluripotent stem cells (iPSCs) harboring distinct deletions in the affected region on chromosome 15. Studying PWS-iPSCs and human parthenogenetic iPSCs unexpectedly revealed substantial upregulation of virtually all maternally expressed genes (MEGs) in the imprinted DLK1-DIO3 locus on chromosome 14. more...

(Submitter supplied) In placental mammals, adaptation to extra-uterine life requires complex metabolic adjustments linked to the abrupt transition from the transplacental transfer of glucose toward the use of fat originating from the mother’s milk as a major energy source. The study of a novel knock-out mouse model led us to identify the biological roles of the miR-379/miR-410 cluster at the imprinted Dlk1-Dio3 region during this metabolic transition. more...

(Submitter supplied) Using NGS approach we performed the search of multiple sclerosis-related miRNAs. We used PBMC as an informative and easily accessible biological material. To exclude bias in miRNA expression levels caused by disease modifying therapies, miRNA profiling was performed in treatment-naïve RRMS patients. Taking into account hypothetic gender specificity in disease pathogenesis we compared miRNA expression in RRMS patients and HCs separately for men and women. more...

(Submitter supplied) Induced pluripotent stem (iPS) cells were produced from reprogramming of somatic cells, and they are shown to possess pluripotent properties similar to embryonic stem (ES) cells. Here we used microarrays to detail the global expression pattern among the ES cells and iPS cells, as well as the original mouse embryo fibroblast (MEF), to identify important players involved in the reprogramming process.

(Submitter supplied) Mice bearing a G12D activating mutation in Kras consistently develop lung adenocarcinomas in a manner analogous to humans. By performing small and large RNA sequencing on KrasG12D tumors from F1 hybrid mice we were able to identify genes and microRNAs differentially expressed in these tumor samples. Quantification of reads that cover single nucleotide polymorphisms that distinguish between the parental mouse strains enabled an analysis of allele specific expression and imprinting status in these tumors.

(Submitter supplied) We analyzed the expression of RNAs and microRNAs in hepatocytes isolated from ApcDeltaHep livers, either ROSA26 or deleted for the b-catenin binding site upstream of the DLK1/DIO3 locus by Crispr/Cas9 (DLK1DeltaWRE). We thus explored if editing of this regulatory site impaired the expression of the entire locus and which signaling pathways were modulated.

(Submitter supplied) Pluripotent cells can be derived from somatic cells by either overexpression of defined transcription factors (resulting in induced pluripotent stem cells (iPSCs)) or by nuclear transfer or cloning (resulting in NT-ESCs). To determine whether cloning further reprograms iPSCs, we used iPSCs as donor cells in nuclear transfer experiments.
