Select changes in microRNA (miRNA) expression correlate with estrogen receptor alpha (ER alpha) expression in breast tumors. miR-21 is higher in ER alpha positive than negative tumors, but no one has examined how estradiol (E(2)) regulates miR-21 in breast cancer cells. Here we report that E(2) inhibits miR-21 expression in MCF-7 human breast cancer cells.(More)
Background: A decoction comprised of Nigella sativa seeds, Hemidesmus indicus root and Smilax glabra rhizome is used to treat cancer patients in Sri Lanka. However, the anti-carcinogenic properties of this decoction have not been experimentally confirmed. The purpose of this study was to determine whether the above decoction could protect against chemically(More)
Resistance to endocrine therapy is a major clinical problem in breast cancer. The role of ERalpha splice variants in endocrine resistance is largely unknown. We observed reduced protein expression of an N-terminally truncated ERalpha46 in endocrine-resistant LCC2, LCC9, and LY2 compared to MCF-7 breast cancer cells. Transfection of LCC9 and LY2 cells with(More)
