Alternative splicing controlled by heterogeneous nuclear ribonucleoprotein L (hnRNP L) regulates development, proliferation and migration of thymic pre-T cells

Project description:The regulation of post-transcriptional modifications of pre-mRNA by alternative splicing is important for cellular function, development and immunity The receptor tyrosine phosphatase CD45, which is expressed on all hematopoietic cells, is known for its role in the development and activation of T cells. To investigate the role of hnRNP L further, we have generated conditional hnRNP L knockout mice carrying floxed alleles and the T-cell specific Lck-Cre recombinase transgene. The Lck-Cre transgene is active in DN3, DN4 as well as in DP and SP cells. We found that deletion of hnRNP L results in a decreased thymic cellularity caused by a partial block at the transition stage between DN4 and DP cells. In addition, hnRNP L-/- thymocytes express aberrant levels of the CD45RA splice isoform and show high levels of phosphorylated Lck at the activator tyrosine Y394 but lacking phosphorylation of the inhibitory tyrosine Y505. This is indicative of an increased basal Lck activation and correlated with a higher proliferation rate of DN4 cells in hnRNP L-/- mice. Deletion of hnRNP L also blocked egress of SP cells to peripheral lymphoid organs and the migration of SP thymocytes in response to the chemokines CCL21 and SDF-1a. Since we found that actin polymerization was also compromised in hnRNP L-/- SP cells, we propose that a defect in the signal transduction cascade downstream of the chemokine receptors CCR7 and CXCR4 caused by the absence of hnRNP L is responsible for this phenotype. Our results indicate that hnRNPL regulates pre-T cell development and migration by regulating CD45 pre-mRNA splicing and chemokine receptor signaling.

Regulatory RNA Apela Is a Component of a Negative Feedback Loop Regulating p53-Mediated Apoptosis in Embryonic Stem Cells (III)

Project description:The goal is to identify RNAs that bind to Hnrnpl (hnRNP L) using RNA immunoprecipitation (RIP) assay. p53+/+ mES cells and p53-/- mES cells were untreated or treated with 0.5 uM Adriamycin for 8 hours. RNA immunoprecipitation was performed using Hnrnpl antibody (Bethyl, Cat#: A311-423A). Total RNA was extracted and subject to RNAseq.

Expression data from Murine T cell in response to cycloheximide treatment

Project description:Cycloheximide has been used for inhibiting protein synthesis in order to identify IL-2 direct targeted genes in T cells, but the effects of cycloheximide itself on genomewide genes are not well defined We conducted a global analysis of cycloheximide regulated genes in mouse T cell line CTLL-2 using Affymetrix mouse genome array, and identified 213 genes differentially expressed (?1.5-fold change) in response to cycloheximide 30min after adding cylcoheximide to T cells cultured without IL-2 for 14 hours. These genes involve in a number biological processes. Keywords: stress response
