T-47D

From Wikipedia, the free encyclopedia
Karyotype of the T47D breast cancer cell line

T-47Dis a humanbreast cancercell linecommonly used in biomedical research involving thehormonalexpression of cancer cells.[1]

Characteristics

[edit]

The cells were derived from thepleural effusionof aductal carcinomafound in themammary glandof an elderly human patient. T-47D cells are distinct from other human breast cancer cells in that theirprogesterone receptorsare not regulated byestradiol,a hormone that is abundant within the cells themselves.[2]

Usage

[edit]

T-47D cells have been employed in studies of the effects ofprogesteroneon breast cancer and the correspondingtranscriptionalregulation caused by introduced drugs.[3]T-47D cells can be implanted intoimmunodeficient mice,formingxenograftsthat can undergo drug testing with corresponding receptor status andangiogenesischanges. The cells have been noted to be extremely resistant toestrogensand antiestrogens, possibly due to inhibition by 5-bromodeoxyuridine and sodium butyrate.[2]
