2. Figure 1
Expression of IL-15, IL-18, and CXCL10 mRNA levels isolated from the endometrium of patients with PCOS and healthy women was measured using real-time RT-PCR. Data are expressed as mean ± SD. Beta-actin mRNA expression arbitrarily assumed the value of 1 and was used to normalize the mRNA expression of each sample; P values refer to unpaired t-test analysis.
