Description
As Prdm16 deficiency reduces self-renewal potential and depletes neural stem cells in culture we decided to investigate the underlying molecular mechanisms of the neural stem cells depletion in the Prdm16 deficient animals. For the experiment we used Prdm16Gt(OST67423)Lex (Prdm16LacZ) genetrap mice obtained from the NIH Mutant Mouse Regional Resource Center (http://www.mmrrc.org/).
Publication Title
Prdm16 promotes stem cell maintenance in multiple tissues, partly by regulating oxidative stress.

Description
Trans-splicing is a post-transcriptional event that joins exons from separate pre-mRNAs. Detection of trans-splicing is usually severely hampered by experimental artifacts and genetic rearrangements. Here, we develop a new computational pipeline, TSscan, which integrates different types of high-throughput long-/short-read transcriptome sequencing of different human embryonic stem cell (hESC) lines to effectively minimize false positives while detecting trans-splicing. Combining TSscan screening with multiple experimental validation steps revealed that most chimeric RNA products were platform-dependent experimental artifacts of RNA sequencing. We successfully identified and confirmed four trans-spliced RNAs, including the first reported trans-spliced large intergenic noncoding RNA ("tsRMST"). We showed that these trans-spliced RNAs were all highly expressed in human pluripotent stem cells and differentially expressed during hESC differentiation. Our results further indicated that tsRMST can contribute to pluripotency maintenance of hESCs by suppressing lineage-specific gene expression through the recruitment of NANOG and the PRC2 complex factor, SUZ12. Taken together, our findings provide important insights into the role of trans-splicing in pluripotency maintenance of hESCs and help to facilitate future studies into trans-splicing, opening up this important but understudied class of post-transcriptional events for comprehensive characterization

Description
GW182 (Tnrc6a) is a key component of RISC (miRNA-Induced Silencing Complex) that plays a critical role in miRNA-mediated gene silencing. Here, we show that GW182 is expressed in the yolk sac endoderm, and that gene-trap disruption of GW182 leads to growth arrest of yolk sac endoderm, impaired hematopoiesis and embryonic lethality.
Publication Title
Trinucleotide repeat containing 6a (Tnrc6a)-mediated microRNA function is required for development of yolk sac endoderm.

Description
Parkinson's disease pathogenesis proceeds through several phases, culminating in the loss of dopaminergic neurons of the substantia nigra (SN). Although the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) model of oxidative SN injury is frequently used to study degeneration of dopaminergic neurons in mice and non-human primates, an understanding of the temporal sequence of molecular events from inhibition of mitochondrial complex 1 to neuronal cell death is limited. Here, microarray analysis and integrative data mining were used to uncover pathways implicated in the progression of changes in dopaminergic neurons after MPTP administration. This approach enabled the identification of small, yet consistently significant, changes in gene expression within the SN of MPTP-treated animals. Such an analysis disclosed dysregulation of genes in three main areas related to neuronal function: cytoskeletal stability and maintenance, synaptic integrity, and cell cycle and apoptosis. The discovery and validation of these alterations provide molecular evidence for an evolving cascade of injury, dysfunction, and cell death.

Description
The feather follicle is a “professional” regenerative organ that undergoes natural cycling and, regeneration after wound plucking. Similar to mammalian hair follicle, dermal papilla (DP) controls feather regeneration, shape, size, and axis. Here we report gene expression profiling for feather DP at different growth stages. For growth phase, we compared gene expression of DP, the ramogenic zone of feather branching epithelium (Erz) and the mesenchymal pulp (Pp). We also compared gene expression of DP at resting phase. To characterize the feather regeneration process, we further profiled gene expression at Day-2 and Day-4 post wound. Our results provide a resource for investigating feather growth and regeneration. Overall design: Examination of gene expression in dermal papilla (DP) at growth phase and resting phase feather follicle, and during feather regeneration.
