Understanding mechanisms that lead to selective motor neuron degeneration requires visualization and cellular identification of vulnerable neurons. Here we report generation and characterization of UCHL1-eGFP and hSOD1(G93A)-UeGFP mice, novel reporter lines for cortical and spinal motor neurons. Corticospinal motor neurons (CSMN) and a subset of spinal motor neurons (SMN) are genetically labele...

Actin, a major component of microfilaments, is involved in various eukaryotic cellular functions. Over the past two decades, actin fused with fluorescent protein has been used as a probe to detect the organization and dynamics of the actin cytoskeleton in living eukaryotic cells. It is generally assumed that the expression of fusion protein of fluorescent protein does not disturb the distributi...

Transgenic pigs have become an attractive research model in the field of translational research, regenerative medicine, and stem cell therapy due to their anatomic, genetic and physiological similarities with humans. The development of fluorescent proteins as molecular tags has allowed investigators to track cell migration and engraftment levels after transplantation. Here we describe the devel...

AIMS Recent studies suggested that human umbilical vein endothelial cells (HUVECs) transdifferentiate into cardiomyocytes and smooth muscle cells in vitro. To test the functional relevance of this observation, we examined the transdifferentiation potential of HUVECs in vivo after intracoronary cell application in Wistar rats. METHODS AND RESULTS SPECT measurements (single photon emission comp...

Psychostimulant-induced alteration of dendritic spines on dopaminoceptive neurons in nucleus accumbens (NAcc) has been hypothesized as an adaptive neuronal response that is linked to long-lasting addictive behaviors. NAcc is largely composed of two distinct subpopulations of medium-sized spiny neurons expressing high levels of either dopamine D1 or D2 receptors. In the present study, we analyze...

To study the profile and regulation of apolipoprotein E (apoE) expression in the CNS, we generated mice in which apoE expression can be detected in vivo with unprecedented sensitivity and resolution. cDNA encoding enhanced green fluorescent protein (EGFP) with a stop codon was inserted by gene targeting into the apoE gene locus (EGFPapoE) immediately after the translation initiation site. Inser...

Interleukin (IL)-6 is a cytokine produced mainly by microglia and astrocytes and plays a pleiotropic role in the central nervous system. In this study, we cloned rat IL-6 cDNA into an enhanced green fluorescent protein (EGFP) or a red fluorescent protein (DsRed2) vector and rat 78-kDa glucose-regulated protein (GRP78) cDNA into an EGFP vector to construct IL-6-EGFP, IL-6-DsRed2, and GRP78-EGFP ...

Abstract Genetic manipulation of Haematococcus pluvialis is difficult because the lack a stable and convenient transformation system. The pH124-EGFP-Ble vector containing ble as selective gene EGFP reporter was constructed employed for effective transformation. H. protoplasts were obtained by treating with cellulase macerozeme. Then polyethylene glycol-mediated established incubating protoplast...

PURPOSE To create the Tg(ccnb1:EGFP)(nt18) zebrafish line that spatially and temporally labels retinal progenitor cells with enhanced green fluorescent protein (EGFP) during zebrafish retinal development and regeneration. METHODS We cloned the 1.5 kb promoter region of the zebrafish cyclin B1 (ccnb1) gene upstream of the EGFP gene in the Tol2 vector, which was used to generate the stable Tg(c...

Hematopoietic Stem Cell (HSC) targeted gene transfer is an attractive treatment option for a number of hematopoietic disorders caused by single gene defects. However, extensive methylation of promoter sequences results in silencing of therapeutic gene expression. The choice of an appropriate promoter is therefore crucial for reproducible, stable and long-term transgene expression in clinical ge...
