Antiproliferative effects of mistletoe (Viscum album L.) extract in urinary bladder carcinoma cell lines.

Background: The aim of the study was to evaluate the antiproliferative potency of Viscum album extract (VA-E) in human bladder carcinoma cell lines with regard to its possible use for intravesical therapy of superficial bladder cancer.

Materials And Methods: Proliferation (MTT-test or 3H-thymidine incorporation), necrotic disintegration (3H-thymidine release of prelabelled cells) and portions of apoptotic and/or necrotic cells (Annexin-V binding, propidium iodide (PI) labelling and DNA-fluorescence profiles by flow cytometry) were measured in four different human bladder carcinoma cell lines (T24, TCCSUP, J82 and UM-UC3) cultured in vitro.

Results: Antiproliferative effects of VA-E were observed in the four bladder carcinoma cell lines tested.
