Mass Spectrometric Analysis of Clomiphene Citrate-induced Changes in the Secretome Profile of PAX8-positive Human Fallopian Tube Secretory Epithelial Cells and Identification of Biomarkers Relevant to Reproduction and Pregnancy

ABSTRACT: Clomiphene citrate (CC) is commonly used for infertility treatments, particularly in intrauterine insemination (IUI) and in vitro fertilization (IVF) programs. Despite its effectiveness in inducing ovulation, it is reported to have a low pregnancy rate compared to letrozole. Further, risks of ectopic pregnancy, miscarriage, and fetal malformations have been reported in CC-induced fertility treatment cycles. The present study aimed at understanding whether these effects are associated with CC-induced changes in the secretome profile of the human PAX8-positive fallopian tube secretory epithelial cells (hPFTSECs). Fallopian tube tissues from healthy women who underwent postpartum tubectomy were enzymatically dissociated and cultured with CC, and their secretomes were analyzed by Liquid Chromatography Tandem Mass Spectrometry (LC-MS/MS) to identify CC-induced alterations.

Project description:Mutations in BRCA1 and BRCA2 genes confer an increased lifetime risk for breast and ovarian cancer. Ovarian cancer risk can be decreased by risk-reducing salpingo-oophorectomy (RRSO). Studies on RRSO material have altered the paradigm of serous ovarian cancer pathogenesis. The purpose of this study was to identify candidate genes possibly involved in pathogenesis of serous ovarian cancer by carrying out a microarray analysis of differentially expressed genes in BRCA1/2- mutation positive ovarian and fallopian tube epithelium derived from RRSO surgery. Freshly frozen ovarian and fallopian tube samples from nine BRCA1/2 mutation carriers scheduled for RRSO were prospectively collected in comparison with five mutation-negative control patients undergoing salpingo-oophorectomy for benign indications. Microarray analysis of genome-wide gene expression was performed on ovarian and fallopian tube samples from BRCA1/2 and control patients. The validation of microarray data was performed by quantitative real-time polymerase chain reaction (qRT-PCR) in selected cases of RRSO samples, and also high grade serous carcinoma samples collected from patients with BRCA phenotype. From 22,733 genes, 454 transcripts were identified that were differentially expressed in BRCA1/2 mutation carriers when statistically compared to controls pooling all ovarian and fallopian tube samples together. Of these, 299 genes were statistically significantly downregulated and 155 genes were upregulated. Differentially expressed genes in BRCA1/2 samples reported here might be involved in serous ovarian carcinogenesis and provide interesting targets for further studies. Both fallopian tube and ovarian samples were collected from each BRCA1/2 mutation carrier resulting in eighteen mutation positive adnexal samples. Both fallopian tube and ovarian control samples were collected from one control patient while either ovarian or fallopian tube sample was available from four control patients, respectively, resulting in 6 adnexal control samples. High quality RNA was available from nine BRCA1/2-mutation positive ovarian and eight BRCA1/2-mutation positive fallopian tube samples and from three control ovarian and three control fallopian tube samples.
