Our goal was to generate xenograft mouse models of human breast cancer based on luciferase-expressing MDA-MB-231 tumor cells that would provide rapid mammary tumor growth; produce metastasis to clinically relevant tissues such as lymph nodes, lung, and bone; and permit sensitive in vivo detection of both primary and secondary tumor sites by bioluminescent(More)
Bioluminescent imaging (BLI) permits sensitive in vivo detection and quantification of cells specifically engineered to emit visible light. Three stable human tumor cell lines engineered to express luciferase were assessed for their tumorigenicity in subcutaneous, intravenous and spontaneous metastasis models. Bioluminescent PC-3M-luc-C6 human prostate(More)
Normal human endothelial cells, like other somatic cells in culture, divide a limited number of times before entering a nondividing state called replicative senescence. Expression of the catalytic component of human telomerase, human telomerase reverse transcriptase (hTERT), extends the life span of human fibroblasts and retinal pigment epithelial cells(More)
BACKGROUND Animal experiments examining hormone-sensitive metastatic prostate cancer using the human LNCaP cell line have been limited to endpoint analyses. To permit longitudinal studies, we generated a luciferase-expressing cell line and used bioluminescent imaging (BLI) to non-invasively monitor the in vivo growth of primary LNCaP tumors and metastasis.(More)
Captopril radionuclide test (CRT) has been introduced in clinical practice as a screening test for renovascular hypertension, since it allows the detection of the decrease of glomerular filtration rate that may be induced by angiotensin converting enzyme inhibition (25 mg oral captopril) in kidneys ipsilateral to a renal artery stenosis. However, due to the(More)
