LM23, a gene expressed specifically in the testis in a stage-specific manner, has a diverse range of functions that are important in both the life and death of spermatogenic cells. The aim of this study was to further investigate the expression of LM23 in the developing rat testis and the biological function of LM23 in proliferation and antiapoptosis in vitro. Semiquantitative reverse transcrip...
Posttranslational modifications of histone amino termini play an important role in modulating chromatin structure and function. Lysine methylation of histones has been well documented, and recently this modification has been linked to cellular processes involving gene transcription and heterochromatin assembly. However, the existence of arginine methylation on histones has remained unclear. Rec...
PURPOSE Idiopathic congenital nystagmus (ICN) is a genetically heterogeneous disease. Thus far, the disease gene has been identified as the FERM domain containing 7 (FRMD7) gene. The purpose of this study was to elucidate the clinical and genetic characteristics of a four- generation Chinese family with ICN. METHODS The clinical data and the genomic DNA of a Chinese ICN family were collected ...
Galpha(i)-coupled receptor stimulation results in epidermal growth factor receptor (EGFR) phosphorylation and MAPK activation. Regulators of G protein signaling (RGS proteins) inhibit G protein-dependent signal transduction by accelerating Galpha(i) GTP hydrolysis, shortening the duration of G protein effector stimulation. RGS16 contains two conserved tyrosine residues in the RGS box, Tyr(168) ...
BACKGROUND/AIMS While recombinant adenoviruses are among the most widely-used gene delivery vectors and usually propagated in HEK-293 cells, generating recombinant adenoviruses remains time-consuming and labor-intense. We sought to develop a rapid adenovirus production and amplification (RAPA) line by assessing human Ad5 genes (E1A, E1B19K/55K, pTP, DBP, and DNA Pol) and OCT1 for their contribu...
Phosphospecific enrichment techniques and mass spectrometry (MS) are essential tools for comprehending the cellular phosphoproteome. Here, we report a fast and simple approach for low sequence-bias phosphoserine (pS) peptide capture and enrichment that is compatible with low biological or clinical sample input. The approach exploits molecularly imprinted polymers (MIPs, "plastic antibodies") fe...
We developed novel methods for analyzing the concentration-response curve of an agonist to estimate the product of observed affinity and intrinsic efficacy, expressed relative to that of a standard agonist. This parameter, termed intrinsic relative activity (RA(i)), is most applicable for the analysis of responses at G protein-coupled receptors. RA(i) is equivalent to the potency ratios that ag...
