BACKGROUND We tested the hypothesis that intracoronary delivery of an adenovirus encoding adenylyl cyclase type VI (Ad.AC(VI)) would be associated with increased left ventricular (LV) function in pigs with congestive heart failure. METHODS AND RESULTS Pigs (52+/-6 kg; n=16) underwent placement of pacemakers, LV pressure transducers, and left atrial and aortic catheters. Physiological and echo...
BACKGROUND Hexavalent chromium [Cr(VI)] is a potent human carcinogen. Occupational exposure has been associated with increased risk of respiratory cancer. Multiple mechanisms have been shown to contribute to Cr(VI) induced carcinogenesis, including DNA damage, genomic instability, and epigenetic modulation, however, the molecular mechanism and downstream genes mediating chromium's carcinogenici...
Hexavalent chromium [Cr(VI)] is a non-essential metal for normal plants and is toxic to plants at high concentrations. However, signaling pathways and molecular mechanisms of its action on cell function and gene expression remain elusive. In this study, we found that Cr(VI) induced endogenous reactive oxygen species (ROS) generation and Ca(2+) accumulation and activated NADPH oxidase and calciu...
The time-course of expression of dbat and dbtnbt genes involved in the later steps of paclitaxel biosynthesis and the intracellular taxane accumulation were investigated through a 64-day subculture interval of VI/M1 and VI/M2 Taxus baccata callus cultures. HPLC proved traces of baccatin III and an intracellular content of paclitaxel up to 90 microg/g DW. The steady-state of the respective gene ...
Hexavalent chromium (Cr(VI)) is a serious environmental pollutant and human toxicant. Mammalian cells are very sensitive to chromate as they lack efficient chromate detoxifying strategy, e.g., chromate-reducing genes that are widely present in prokaryotes. To test whether introduction of prokaryotic chromate-reducing gene into mammalian cells could render higher chromate resistance, an Escheric...
Myosin VI, one of the so-called unconventional myosins, is an actin-based molecular motor involved in intracellular vesicle and organelle transport. In human prostate, myosin VI is expressed in prostate epithelium. We examined the effect of myosin VI downregulation in the LNCaP human prostate cancer cell line using an RNA interference approach. Further, the expression of myosin VI in human pros...
We have shown previously that gene VI of cauliflower mosaic virus (CaMV) strain D4 governs systemic infection of Nicotiana bigelovii and that transgenic N. bigelovii expressing the D4 gene VI product can complement at least one CaMV isolate for long-distance transport. We have now found that DNA of two other isolates of CaMV recombine with the gene VI coding sequence present in the transgenic p...
To gain insight into the molecular basis of annexin gene expression we have analysed the annexin I and VI gene promoters. A previously described 881 bp sequence immediately upstream of the annexin I transcription start site and a similar size fragment proximal to the annexin VI transcription start site both drove expression of the luciferase reporter gene in fibroblasts and epithelial cells. Ne...
Recombinant vectors based on adeno-associated virus serotype 8 (AAV8) have been successfully used in the clinic and hold great promise for liver-directed gene therapy. Preexisting immunity against AAV8 or the development of antibodies against the therapeutic transgene product might negatively affect the outcomes of gene therapy. In the prospect of an AAV8-mediated, liver-directed gene therapy c...
We have shown previously that gene VI of cauliflower mosaic virus (CaMV) strain D4 governs systemic infection of Nicotiana bigelovii and that transgenic N. bigelovii expressing the 0 4 gene VI product can complement at least one CaMV isolate for long-distance transport. We have now found that DNA of two other isolates of CaMV recombine with the gene VI coding sequence present in the transgenic ...
