Rosiglitazone and Pioglitazone Alter Aromatase Kinetic Properties in Human Granulosa Cells

<table>Effects of TZDs on aromatase enzyme kinetics when androstenedione was used as substrate. (a) The Lineweaver-Burk plot (reciprocal velocities of aromatase activity against reciprocal androstenedione concentration) in the absence of rosiglitazone or pioglitazone. (b) The Lineweaver-Burk plot in the presence of rosiglitazone. (c) The Lineweaver-Burk plot in the presence of pioglitazone. (d) Comparison of the Lineweaver-Burk plots in the presence or absence of rosiglitazone or pioglitazone. <svg height="10.575" id="M22" style="vertical-align:-0.20064pt" version="1.1" viewbox="0 0 12.625 10.575" width="12.625" xmlns="http://www.w3.org/2000/svg">
