Are paired samples of endometrium and ovarian endometriomas synchronous with each other throughout the menstrual cycle?
The expression levels of 57 endometrial receptivity-associated genes were determined from matched endometrial and endometrioma samples (n=31) collected from women with endometriosis throughout the menstrual cycle.
The expression profile of endometrial receptivity genes divided endometrial samples according to their menstrual cycle phase. Endometrioma samples grouped together irrespective of the menstrual cycle phase and formed a cluster distinct from endometrial samples. Pairwise comparison showed 21, 16, 33 and 23 differentially expressed genes (adjusted P < 0.001-0.05) between the lesions and endometria collected in the proliferative, early-secretory, mid-secretory and late-secretory menstrual cycle phases, respectively, confirming the distinct expression profiles of endometrium and endometrioma.
No menstrual cycle synchronicity was found between matched eutopic and ectopic endometrium, suggesting that the concept of cycling endometrial tissue inside the endometrioma should be revised.
子宫内膜和卵巢子宫内膜异位症的配对样本在整个月经周期中是否同步？
从患有子宫内膜异位症的女性在整个月经周期中采集的 31 对子宫内膜和子宫内膜异位症样本（n=31）中确定了 57 个与子宫内膜容受性相关的基因的表达水平。
子宫内膜容受性基因的表达谱根据月经周期阶段将子宫内膜样本进行了分类。子宫内膜异位症样本无论月经周期阶段如何都聚集在一起，并形成了与子宫内膜样本不同的聚类。两两比较显示，在增殖期、早期分泌期、中期分泌期和晚期分泌期采集的病变和子宫内膜之间分别有 21、16、33 和 23 个差异表达基因（调整后的 P 值 < 0.001-0.05），证实了子宫内膜和子宫内膜异位症的明显不同的表达谱。
在配对的在位和异位子宫内膜之间没有发现月经周期同步性，这表明应该修正子宫内膜异位症内周期性子宫内膜组织的概念。
