Kioka N, Yamano Y, Komano T, Ueda K: Heat-shock responsive elements in the induction of the multidrug resistance gene (MDR1). FEBS Lett. 1992 Apr 13;301(1):37-40. The MDR1 gene, considered to be involved in multidrug resistance of cancer cells, is expressed in liver, kidney, small intestine and the blood-brain barrier. We investigated MDR1 gene expression in the well-differentiated hepatoma cell line HepG2 after exposure to several stresses and found that sodium arsenite treatment increased MDR1 gene expression 2.6-fold. Deletion analysis of the MDR1 promoter indicated that the transcriptional activation after exposure to arsenite depends on a 60-bp region containing two heat-shock responsive elements. |
