Transgenic Del1 mice harboring a deletion mutation in the cartilage-specific type II collagen gene were used for a systematic study on the dose-dependent effects of this dominant mutation on the embryonic development and growth of the vertebral column. Skeletal staining of homozygous and heterozygous Del1 mice and their nontransgenic littermates with Alcian(More)
Conditionally replicative adenovirus (CRAD) is an attractive anticancer agent as it can selectively replicate in tumor cells. Expression of telomerase reverse transcriptase (TERT) is a unique tumor cell characteristic, being absent in normal postmitotic cells. Thus, we constructed a TERT promoter regulated CRAD for tumor-specific oncolysis by replacing the(More)
Tumor-targeted replicating viruses are being developed as a novel class of oncolytic agents. Vesicular stomatitis virus (VSV) is a negative-strand RNA virus with inherent specificity for replication in tumor cells due to their attenuated antiviral responses. VSV as an oncolytic virus is particularly appealing for its exceptionally rapid replication rate in(More)
BACKGROUND Macrophages associated with arterial wall lipid deposition contribute to inflammatory processes. Tissue factor (TF) has been implicated in the thrombogenicity of atherosclerotic plaques. Intimal cells undergoing apoptosis have been postulated as a source for TF. However, there is only limited knowledge of cell type, plaque component, and(More)
Head and neck squamous cell carcinoma (HNSCC) is a common and often devastating disease without curative treatment when advanced or recurrent. The aim of this study was to assess whether capsid-modified oncolytic adenoviruses have therapeutic efficacy in HNSCC low passage tumour cell cultures and if it could be further improved by combination with(More)
Targeted antiangiogenic gene therapy is an attractive approach to treat metastatic cancer. However, the relative paucity of the receptors of the commonly used adenovirus serotype 5 in endothelial cells as compared with liver cells undermines the use of this vector for targeting the endothelial cells in tumors. To overcome this problem, we analyzed the(More)
BACKGROUND Doxorubicin is an effective anticancer drug. The major limitation to its use is the induction of dose-dependent cardiomyopathy. No specific treatment exists for doxorubicin-induced cardiomyopathy and treatments used for other forms of heart failure have only limited beneficial effects. The contraction-relaxation cycle of the heart is controlled(More)
We have constructed cDNA clones covering the entire coding region of mouse, human and rabbit preprocathepsin K mRNA for studies on bone turnover. The clone pMCatK-1 for mouse cathepsin K shares 87% nucleotide homology with the corresponding human and rabbit sequences. Analysis of a panel of mouse tissues for tissue distribution of cathepsin K mRNA revealed(More)
Cartilage matrix is an interacting multicomponent system of collagen fibrils, fibril-associated small proteoglycans, and large proteoglycans and glycoproteins entrapped within the fibrillar network. In order to better understand the relationships between these different components we have constructed short cDNA clones for detection of mRNAs for two major(More)
Conditionally replicating adenoviruses (CRADs) are a novel strategy in cancer treatment and clinical trials using CRADs targeted to tumor cells have been reported recently. We hypothesized that it would be possible to construct CRADs targeted to dividing endothelial cells, which are present in the tumor endothelium. We utilized the regulatory elements of(More)
