abstract background: the aims of this study were to assay the activity of adenosine deaminase (ada) in estrogen receptor positive (mcf-7) and negative (mda-mb468) breast cancer cell lines. methods: mda-mb468 and mcf-7 breast cancer cell lines were cultured in complete medium, striped serum with and without 0.0 1~-lm diethylstilbestrol (des), complete medium in the presence and absence of 111m t...
Estrogen receptors (ERs) orchestrate both transcriptional and non-genomic functions in response to estrogens, xenoestrogens and signals emanating from growth factor signalling pathways. The pleiotropic and tissue-specific effects of estrogens are likely to be mediated by the differential expression of distinct estrogen receptor subtypes (ERalpha and ERbeta) and their coregulators. The recent an...
A nanomechanical transducer is developed to detect and screen endocrine disrupting chemicals (EDCs) combining fluidic sample injection and delivery with bioreceptor protein functionalized microcantilevers (MCs). The adverse affects of EDCs on the endocrine system of humans, livestock, and wildlife provides strong motivation for advances in analytical detection and monitoring techniques. The com...
The combined effects of tamoxifen, a competitive inhibitor of estrogen, and type I or II interferons on the proliferation of several human breast cancer cell lines in vitro were examined. Additive antiproliferative effects were observed with interferons and tamoxifen, in two estrogen receptor positive cell lines, MCF-7 and T-47D. In MCF-7 cells neither beta ser interferon, gamma interferon, nor...
