Calcitriol or 1,25-dihydroxyvitamin D3, the hormonally active form of vitamin D, as well as vitamin D analogs, has been shown to increase sensitivity to ionizing radiation in breast tumor cells. The current studies indicate that the combination of 1,25-dihydroxyvitamin D3 with radiation appears to kill p53 wild-type, estrogen receptor-positive ZR-75-1(More)
OBJECTIVES To compare the expression of nuclear receptor coregulators in normal and malignant human endometrium and to identify any relationship to grade, stage, age, depth of myometrial invasion, estrogen receptor alpha (ERalpha), or progesterone receptor (PR) expression. METHODS Gene expression of SRC-1, SRC-2, SRC-3, N-CoR, SMRT, ERalpha, and PR was(More)
During large-scale manufacturing of an IgG1 monoclonal antibody in Chinese hamster ovary (CHO) cells, reduction of the antibody's disulfide bonds was observed. We present evidence that mammalian thioredoxin 1 (TXN1) is the terminal enzyme responsible for this reduction event. We demonstrate a marked prevention of IgG1 disulfide bond reduction in a(More)
PURPOSE The expression of c-Met, the receptor protein tyrosine kinase for hepatocyte growth factor/scatter factor, frequently increases during prostate tumor progression. However, whether reduced c-Met expression inhibits tumor growth and metastasis has not been ascertained. EXPERIMENTAL DESIGN c-Met expression was reduced by infection of an adenovirus(More)
Bioluminescent resonance energy transfer (BRET2) is a recently developed technology for the measurement of protein-protein interactions in a live, cell-based system. BRET2 is characterized by the efficient transfer of excited energy between a bioluminescent donor molecule (Renilla luciferase) and a fluorescent acceptor molecule (a mutant of Green(More)
Bioluminescent Resonance Energy Transfer is a naturally occurring phenomenon that can be exploited to explore protein-protein interactions in real-time in intact cells and cellular extracts. It detects energy transferred between a bioluminescent donor enzyme (Renilla luciferase) fusion protein and a fluorescent (GFP(2), a mutant of Green Fluorescent(More)
