摘要

This study examined the changes in cellular glucose uptake induced by 2,3,7,8 tetrachlorodibenzo-p-dioxin (TCDD) as measured by quantification of intracellular radioactivity in the NIH 3T3 L1 preadipocyte cell line after a 30-minute incubation with the non-metabolizable radioactive analogue of glucose, 3-O-methyl-D-[1-3H] glucose. Treatment of differentiated NIH 3T3 L1 cells with TCDD produced a time- and dose-dependent decrease in the cellular uptake of glucose. Treatment of cells for 3 hr with 10(-8) M TCDD significantly reduced glucose uptake to about 10% of control values (p
