The activation dynamics of the transcription factor NF-kappaB exhibit damped oscillatory behavior when cells are stimulated by tumor necrosis factor-alpha (TNFalpha) but stable behavior when stimulated by lipopolysaccharide (LPS). LPS binding to Toll-like receptor 4 (TLR4) causes activation of NF-kappaB that requires two downstream pathways, each of which(More)
The transcription factor NF-kappaB regulates a wide variety of genes involved in multiple processes. Although the apparent consensus sequence of DNA binding sites for NF-kappaB (kappaB sites) is very broad, the sites active in any one gene show remarkable evolutionary stability. Using a lentivirus-based methodology for implantation of gene regulatory(More)
the NF-␬B family are involved in gene activation: p50, p52, p65, and cRel. They are the mature gene products Division of Biology and they homo-or heterodimerize with one another to California Institute of Technology bind DNA. It is noteworthy that mice deficient in a single Pasadena, California 91125 NF-␬B/Rel family member exhibit unique, largely(More)
BACKGROUND The purpose of this study was to characterise the oncogenic roles of C35, a novel protein binding partner of ΔNp73, in ovarian cancer and to investigate the functional significance of C35-ΔNp73 interaction in the regulation of chemo-resistance. METHODS C35 expression was evaluated by quantitative real-time PCR in human ovarian cancer tissues(More)
