ABSTRACT
RESEARCH QUESTION How does mucin MUC20 expression change during the menstrual cycle in different cell types of human endometrium? DESIGN:
Study involved examination of MUC20 expression in two previously published RNA-seq datasets in whole endometrial tissue (nâ¯=â¯10), sorted endometrial epithelial (nâ¯=â¯44) or stromal (nâ¯=â¯42) cell samples. RNA-Seq results were validated by quantitative reverse transcription polymerase chain reaction (qRT-PCR) in whole tissue (nâ¯=â¯10), sorted epithelial (nâ¯=â¯17) and stromal (nâ¯=â¯17) cell samples. MUC20 protein localization and expression were analysed in human endometrium by immunohistochemical analysis of intact endometrial tissue (nâ¯=â¯6) and also Western blot of cultured stromal and epithelial cells (nâ¯=â¯2).RESULTS:
MUC20 is differentially expressed in the endometrium between the pre-receptive and receptive phases. We show that MUC20 is predominantly expressed by epithelial cells of the receptive endometrium, both at the mRNA (RNA-Seq, Pâ¯=â¯0.005; qRT-PCR, Pâ¯=â¯0.039) and protein levels (Western blot; immunohistochemistry, Pâ¯=â¯0.029).CONCLUSION:
Our results indicate MUC20 as a novel marker of mid-secretory endometrial biology. We propose a model of MUC20 function in the hepatocyte growth factor (HGF)-activated mesenchymal-epithelial transition (MET) receptor signalling specifically in the receptive phase. Further investigations should reveal the precise function of MUC20 in human endometrium and the possible connection between MUC20 and HGF-activated MET receptor signalling. MUC20 could potentially be included in the list of endometrial receptivity markers after further clinical validation.Palavras-chave
