During B-cell development, RAG endonuclease cleaves immunoglobulin heavy chain (IgH) V, D, and J gene segments and orchestrates their fusion as deletional events that assemble a V(D)J exon in the same transcriptional orientation as adjacent Cμ constant region exons. In mice, six additional sets of constant region exons (CHs) lie 100-200 kilobases downstream(More)
BACKGROUND AIMS The engraftment of mesenchymal stem cells (MSCs) is reported to promote recovery of renal function in animal models of acute kidney injury (AKI). However, it is unknown whether mesenchymal-like progenitors (MPs) derived from human embryonic stem cells (hESCs) can mediate similar therapeutic effects. We investigated the responses of recipient(More)
Steady-state gene expression across the cell cycle has been studied extensively. However, transcriptional gene regulation and the dynamics of histone modification at different cell-cycle stages are largely unknown. By applying a combination of global nuclear run-on sequencing (GRO-seq), RNA sequencing (RNA-seq), and histone-modification Chip sequencing(More)
Nuclear modifier gene(s) was proposed to modulate the phenotypic expression of mitochondrial DNA mutation(s). Our previous investigations revealed that a nuclear modifier allele (A10S) in TRMU (methylaminomethyl-2-thiouridylate-methyltransferase) related to tRNA modification interacts with 12S rRNA 1555A→G mutation to cause deafness. The A10S mutation(More)
OBJECTIVE To observe the change of c-fos protein(Fos) and nerve growth factor receptor (NGFR) staining in the brain of rat after experimental brain contusion. METHODS Immunohistochemistry of c-fos and NGFR were applied to investigate the brain contusion. RESULTS (1) The expression of Fos protein could be observed at 0.5 h after injury and then increased(More)
