The purpose of this study is to establish a gene delivery system for interstitial tissue-specific protein expression in mice testes using modified recombinant baculovirus. Green fluorescent protein (GFP)-expressing recombinant baculovirus (GFP-baculovirus), in which the insect cell-specific polyhedron promoter was replaced by the cytomegalovirus (CMV)-IE promoter, was used to transfect testicul...

I discovered the green fluorescent protein GFP from the jellyfish Aequorea aequorea in 1961 as a byproduct of the Ca-sensitive photoprotein aequorin (Shimomura et al., 1962; Johnson et al., 1962), and identified its chromophore in 1979 (Shimomura, 1979). GFP was a beautiful protein but it remained useless for the next 30 years after the discovery. My story begins in 1945, the year the city of N...

Activation of the cAMP/cAMP-dependent PKA pathway leads to relaxation of airway smooth muscle (ASM). The purpose of this study was to examine the role of the small heat shock-related protein HSP20 in mediating PKA-dependent ASM relaxation. Human ASM cells were engineered to constitutively express a green fluorescent protein-PKA inhibitory fusion protein (PKI-GFP) or GFP alone. Activation of the...

Previously, we described GFP-spectrin, a membrane-localized derivative of the green fluorescent protein that can be employed as a marker during the simultaneous identification of transfected cells and cell cycle analysis by flow cytometry (Kalejta et al., Cytometry 29: 286-291, 1997). A membrane-anchored GFP fusion protein is necessary because the ethanol permeabilization step required to achie...

The formation of protein aggregates is a hallmark neurodegenerative diseases. Observations on patient samples and model systems demonstrated links between aggregate declining mitochondrial functionality, but causalities remain unclear. We used Saccharomyces cerevisiae to analyze how processes regulate the behavior aggregation-prone polyQ derived from human huntingtin. Expression Q97-GFP rapidly...

background: bone marrow mesenchymal stem cells (bmscs) are the key to regenerative wound healing. mscs have spatial memory and respond to local environment. the goal of this study was to evaluate the use of systemic and intralesional transplantation of bmscs for regeneration of oral mucosa in an in vivo dog model. materials and methods: transplantation of undifferentiated green fluorescent prot...

The Bamboo mosaic virus (BaMV) is a positive-sense, single-stranded RNA virus. Previously, we identified that the chloroplast phosphoglycerate kinase (chl-PGK) from Nicotiana benthamiana is one of the viral RNA binding proteins involved in the BaMV infection cycle. Because chl-PGK is transported to the chloroplast, we hypothesized that chl-PGK might be involved in viral RNA localization in the ...

agrobacterium tumefaciens is capable of gene transfer to both plant and non-plant organisms. indeed, upon infection of eukaryotic cells, agrobacterium tumefaciens transfers a piece of its tumor inducing (ti)-plasmid, called t-dna, to the host cell nucleus, which subsequently integrates into the host genome. the vird2 virulence protein which has relaxase endonuclease activities covalently binds ...
