Description
Sensorimotor dysfunction following incomplete spinal cord injury (SCI) is often characterized by paralysis, spasticity and pain. Previously, we showed that intrathecal (i.t.) administration of the albumin-oleic acid (A-OA) complex in rats with SCI produced partial improvement of these symptoms and that oral 2-hydroxyoleic acid (HOA), a non-hydrolyzable OA analogue), was efficacious in the modulation and treatment of nociception and pain-related anxiety, respectively. Here we observed that intrathecal treatment with the complex albumin-HOA (A-HOA) every 3 days following T9 spinal contusion injury promoted significant recovery in locomotor function and marked an inhibition of TA noxious reflex activity (i.e., nociception) in Wistar rats. To investigate the mechanism of action of A-HOA, microarray analysis was carried out in the spinal cord lesion area. Representative genes involved in pain and neuroregeneration were selected to validate the changes observed in the microarray analysis by quantitative real-time RT-PCR. Comparison of the expression between healthy rats, SCI rats, and SCI treated with A-HOA rats revealed relevant changes in the expression of genes associated with neuronal morphogenesis and growth, neuronal survival, pain and inflammation. Thus, treatment with A-HOA not only induced a significant overexpression of growth and differentiation factor 10 (GDF10), tenascin C (TNC), aspirin (ASPN) and sushi-repeat-containing X-linked 2 (SRPX2), but also a significant reduction in the expression of prostaglandin E synthase (PTGES) and phospholipases A1 and A2 (PLA1/2). Currently, SCI has very important unmet clinical needs. A-HOA proved to downregulate genes involved in inflammation and upregulate genes involved in neuron growth, which balanced the important body response to medular lesion and allowed recovery from paralysis and pain.

Description
Analysis of C4-2 prostate cancer cell line after 6 hrs of treatment with TOPK-32. PBK is overexpressed in a number of solid tumours, including prostate cancer. Results provide insight into the molecular mechanisms of PBK in prostate carcinogenesis. Overall design: This experiment was designed to understand the regulation of transcriptome by PDZ domain binding kinase, which is an important kinase with role in cell cycle. The cells were treated with a catalytic inhibitor TOPK32 which inhibits the kinase activity of PBK protein.

Description
In this study, mRNA expression profiles of 113 primary untreated human neuroblastoma samples were compared with the aim to identify prognostic exon and gene sets as well as parameters associated with alternative exon use. The primary neuroblastoma specimens were from tumor banks in Cologne or Essen, Germany, Ghent, Belgium and Valencia, Spain. All patients were diagnosed between 1998 and 2007 and treated according to the German Neuroblastoma trials NB97, NB 2004 or the SIOPEN protocol.

Description
Although lincRNAs are implicated in regulating gene expression in various tissues, little is known about lincRNA transcriptomes in the T cell lineages. Here we identify 1,524 lincRNAs in 42 T cell samples from early T cell progenitors to terminally differentiated T helper subsets. Our analysis revealed highly dynamic and cell-specific expression patterns of lincRNAs during T cell differentiation. Importantly, these lincRNAs are located in genomic regions enriched for protein-coding genes with immune-regulatory functions. Many of these transcripts are bound and regulated by the key T cell transcription factors, T-bet, GATA3, STAT4 and STAT6. We demonstrate that the lincRNA LincR-Ccr2-5''AS, together with GATA3, is an essential component of a regulatory circuit in Th2-specific gene expression. Overall design: To obtain comprehensive profiles of lincRNA expression during the development and differentiation of T cell lineages, we purified CD4-CD8 double negative (DN) cells (DN1, DN2, DN3 and DN4), double positive (DP) cells (CD4+CD8+CD3low and CD4+CD8intCD69+), single positive (SP) CD4 and CD8 cells, and thymic-derived regulatory T cells (tTreg) from thymi of C57BL/6 mice. Additionally, we obtained Th1, Th2, Th17 and iTreg cells by in vitro differentiation of naïve CD4 T cells for a various length of time in culture (4 hrs, 8 hrs, 12 hrs, 24 hrs, 48 hrs, 72 hrs, 1 week, 2weeks). Total and/or polyadenylated RNAs from these cells was analyzed using RNA-Seq. To understand the regulation of lincRNAs by T cell master regulator T-bet, we compared the transcriptiomes between T-bet deficient Th1 cells and control Th1 cells. We did similar experiments and data analysis for STAT4 (Th1), GATA3 (Th2) and STAT6 (Th2). Finally, to address the funcation of a Th2-specifically expressed lincRNA, lincR-Ccr2-5''AS, we compared the transcriptomes between lincR-Ccr2-5''AS knockdown Th2 cells and control Th2 cells.
