lysolecithin/breast neoplasms

An important factor which determines the movement of cholesterol in and out of the cells is the free cholesterol (FC)/esterified cholesterol (EC) ratio in the plasma. Although this ratio has been shown to be increased in several types of malignancies in humans as well as experimental animals, it is

Sialyltransferase activity in normal human breast tissue and tumors was investigated with lactose, desialylated fetuin, and bovine submaxillary mucin as the acceptors. While microsomal preparations from the normal tissue showed little or no sialyltransferase activity toward these acceptors, tumors

Flow cytometry (FCM) is useful for measuring DNA content as related to cell cycle position. We have extended this technology by developing a method that measures cellular DNA content using propidium iodide after permeabilization with lysolecithin. This technique maintains cell integrity such that

Interdisciplinary cooperation between basic and clinical research has resulted in the discovery and development of alkylphosphocholines, a new class of substances for the treatment of breast cancer. In contrast to most antitumor substances, the alkylphosphocholines do not attack the cell nucleus,
