We used a 2',3'-cyclic nucleotide 3'-phosphodiesterase (CNP)-enhanced green fluorescent protein (EGFP) transgenic mouse to study postnatal subventricular zone (SVZ) progenitor fate, with a focus on the olfactory bulb (OB). The postnatal OB of the CNP-EGFP mouse contained EGFP+ interneurons and oligodendrocytes. In the anterior SVZ, the majority of EGFP+ progenitors were NG2+. These NG2+/EGFP+ p...

The co-chaperone murine stress-inducible protein 1 (mSTI1), an Hsp70/Hsp90 organizing protein (Hop) homologue, mediates the assembly of the Hsp70/Hsp90 chaperone heterocomplex. The mSTI1 protein can be phosphorylated in vitro by cell cycle kinases proximal to a putative nuclear localization signal (NLS), which substantiated a predicted casein kinase II (CKII)-cdc2 kinase-NLS (CcN) motif at posi...

Under physiological conditions, the voltage-gated sodium channel Nav1.8 is expressed almost exclusively in primary sensory neurons. The mechanism restricting Nav1.8 expression is not entirely clear, but we have previously described a 3.7 kb fragment of the Scn10a promoter capable of recapitulating the tissue-specific expression of Nav1.8 in transfected neurons and cell lines (Puhl and Ikeda, 20...

PURPOSE The oncolytic effects of a systemically delivered, replicating, double-deleted vaccinia virus has been previously shown for the treatment of many cancers, including colon, ovarian, and others. The purpose of this study was to investigate the oncolytic potential of double-deleted vaccinia virus alone or in combination with rapamycin or cyclophosphamide to treat malignant gliomas in vitro...

Inflammatory chemokines can be selectively released from Weibel-Palade bodies (WPBs) during kiss-and-run exocytosis. Such selectivity may arise from molecular size filtering by the fusion pore, however differential intra-WPB cargo re-mobilisation following fusion-induced structural changes within the WPB may also contribute to this process. To determine whether WPB cargo molecules are different...

A new genetic marker was created in which sequences from enhanced green fluorescent protein were fused to those of puromycin N-acetyl transferase. The resulting fusion protein (EGFP-puro) conferred both green fluorescence and resistance to puromycin when expressed in mammalian cells. The utility of EGFP-puro as a selectable/screenable marker was demonstrated by the ease with which a recombinant...

A functional calcineurin A fusion to enhanced green fluorescent protein (EGFP), CnaA-EGFP, was expressed in the Aspergillus fumigatus DeltacnaA mutant. CnaA-EGFP localized in actively growing hyphal tips, at the septa, and at junctions between the vesicle and phialides in an actin-dependent manner. This is the first study to implicate calcineurin in septum formation and conidiophore development...

Luminal acidification is important for the maturation of secretory granules, yet little is known regarding the regulation of pH within them. A pH-sensitive green fluorescent protein (EGFP) was targeted to secretory granules in RIN1046-38 insulinoma cells by using a construct in which the EGFP gene was preceded by the nucleotide sequence for human growth hormone. Stimulatory levels of glucose do...

We previously showed that a systemic inhibitor of gp91(phox) (nox2)-based NAD(P)H oxidase abolishes angiotensin II (Ang II)-induced vascular hypertrophy. In the present study, we tested whether perivascular transfection with Ad-gp91ds-eGFP (an adenoviral bicistronic construct targeting NAD(P)H oxidase in fibroblasts) or controls Ad-CMV-eGFP and Ad-scrmb-eGFP would affect medial hypertrophy in r...

The cone function is essential to mediate high visual acuity, color vision, and daylight vision. Inherited cone dystrophies and age-related macular degeneration affect a substantial percentage of the world population. To identify and isolate the most competent cells for transplantation and integration into the retina, cone tracing during development would be an important added value. To that ai...
