abstractText | Here we show that the cell-surface expression of the alpha subunit of H(+)-ATP synthase is markedly increased during adipocyte differentiation. Treatment of differentiated adipocytes with small molecule inhibitors of H(+)-ATP synthase or antibodies against alpha and beta subunits of H(+)-ATP synthase leads to a decrease in cytosolic lipid droplet accumulation. Apolipoprotein A-I, which has been shown to bind to the ectopic beta-chain of H(+)-ATP synthase and inhibit the activity of cell-surface H(+)-ATP synthase, also was found to inhibit cytosolic lipid accumulation. These results suggest that the cell-surface H(+)-ATP synthase has a previously unsuspected role in lipid metabolism in adipocytes. |
