Figure 4. Expression of wt-ERα, ERαDel.2, ERαDel.4, ERαDel.7 and ERαDel.3,4 in patients with (n = 30) and without endometriosis (control, n = 28), without taking into account the phase of the menstrual cycle.

When cycle phase was ignored, the expression of ERαDel.4 and ERαDel.7 are significantly different between patients with and without endometriosis. Data from three to six experiments are expressed in logarithmic scale in relation to GAPDH mRNA levels (mean values ± standard deviation), ^*p < 0.05, ^**p < 0.01.
