Table 2. Inhibitory effect of the basal potassium current (% of basal I_K) induced by 17β-estradiol and progesterone (1–100 μmol/L) on A7r5 cells. Each value represents the mean of the % of variation of basal I_K±SEM from the number of experiments shown in the brackets.

Concentration	17 β-estradiol	Progesterone
1 μmol/L	2.1%±2.4% (n5)	−1.4%±3.8% (n8)
10 μmol/L	−1.1%±5.7% (n6)	1.8%±3.1% (n7)
30 μmol/L	−3.7%±2.8% (n5)	−0.9%±4.3% (n5)
100 μmol/L	−2.1%±3.2% (n5)	−3.8%±0.8% (n5)
