Induced cytoskeletal changes in bovine pulmonary artery endothelial cells by resveratrol and the accompanying modified responses to arterial shear stress

Table 1 Use of inhibitors to probe the basis for elongation of BPAEC induced by resveratrol. These experiments used passages 4-5 BPAEC cells. The cells on cover slips were incubated with inhibitors for 24 h, before 100 μM resveratrol was added and incubation was continued for an additional 40 h. An exception was quin2-AM, which was applied 1 h prior to resveratrol treatment.

^a Results in this table were averaged from 4 separate experiments, each performed with a different preparation of primary BPAEC's. Since growth of control cells as well as their response to resveratrol and addition of inhibitors differed between BPAEC preparations, cells showing the elongated shape in each experiment were calculated as a percent of total cells counted (ranging from 60-700). The numbers obtained in this manner were used to calculate the mean (%)± SD, as shown.
