Comparative endometrial proteomics among fertile women, intrauterine device carriers, and recurrent implantation failure patients using iTRAQ methodology

Project description:Endometrial receptivity is imperative to achieving pregnancy in humans. A disruption in the development of endometrial receptivity is responsible for recurrent implantation failures (RIF) of endometrial origin. To further understand the molecular mechanisms behind the endometrial receptivity process, we used the 8-plex isobaric tag for relative and absolute quantitation (iTRAQ) method to compare and quantify the proteomes from endometrial biopsies of three different endometrial statuses (fertile women, IUD carriers and RIF patients). Overall, iTRAQ allowed to identify 1,889 non-redundant proteins. Of these, 188 were differentially expressed proteins (DEP) (p-value < 0.05) among the three endometrial groups. Pairwise comparisons revealed 133 significant DEP in fertile vs. IUD carriers and 158 DEP in RIF vs. IUD carriers. However, no DEP were identified between fertile and RIF patients. Western blot validation of three DEP involved in endometrial receptivity (Plastin 2, Lactotrasferrin, and Lysozyme) confirmed our iTRAQ results. Moreover, functional KEGG enrichment revealed that complement and coagulation cascades and peroxisome were the two most significant pathways for the RIF vs. IUD comparison and ribosome and spliceosome for the fertile vs. IUD comparison, as possible important pathways involved in the endometrial receptivity acquisition. Our findings confirm that an IUD introduces numerous changes in the endometrial protein profile when compared to fertile and RIF endometria, revealing some key proteins involved in endometrial receptivity. The lack of DEP between fertile and RIF patient endometria suggest either that idiopathic RIF may not have an endometrial origin, with other as-yet-unknown factors involved.

Olfactory cleft proteome does not reflect olfactory performance in patients with idiopathic and postinfectious olfactory disorder: A pilot study.

Project description:The pathophysiology of post-infectious and idiopathic olfactory loss is still poorly delineated. Since proteins are key players in olfaction and technical advances including LC-MS/MS mass spectrometry give us the opportunity for detailed analysis of the nasal mucus proteome we aimed to undertake a comparative analysis of the olfactory cleft mucus proteome using mucus samples of the olfactory cleft in patients with idiopathic and postinfectious olfactory disorders versus healthy controls. The study was conceived as a pilot study and included 7 patients with idiopathic hyp- and anosmia, 7 patients with postinfectious hyp- and anosmia and 7 healthy controls. In total, 1117 different proteins were detected in at least 5 patients in at least one group. No significant different overall protein concentrations in patients compared to healthy controls (0.4614 µg/µL, SD=0.26273 vs. 0.5143 µg/µL, SD=3087; p=0.689) were found. Significant correlation regarding olfactory test results (TDI score) and protein concentrations (r=0.114, p=0.623) were either found. Results of this study did not show significant differences regarding the proteomic composition of the olfactory cleft mucus between patients suffering from postinfectious and idiopathic dysosmia versus healthy controls. Thus, central olfactory processing pathways may play a role in idiopathic and postinfectious olfactory disorders.

Different expression of circRNAs in blood from idiopathic short stature patients and healthy controls

Project description:Idiopathic short stature is diagnosed by a standing height of less than two standard deviation scores in a specific population adjusted for age and gender and the exclusion of identifiable diseases. A series of studies have confirmed that noncoding RNAs can regulate the chondrocyte proliferation, hypertrophy, and endochondral ossification in the growth plate. In order to analyze and find differentially expressed circRNAs in Idiopathic short stature and healthy controls, we aimed to explore whether differentially expressed circRNAs in idiopathic short stature. Four pairs of blood samples were subjected to microarray analysis using the Arraystar Human CircRNAs Microarray v2 (Arraystar, USA). Compared to normal individuals, in ISS patients, the expression levels of 83 circRNAs were upregulated and those of 62 were downregulated.

Gene expression profiling of idiopathic pulmonary fibrosis and non-specific interstitial pneumonia

Project description:Idiopathic pulmonary fibrosis (IPF) and non-specific interstitial pneumonia (NSIP) are the 2 most common forms of idiopathic interstitial pneumonia. Response to therapy and prognosis are remarkably different. The clinical-radiographic distinction between IPF and NSIP may be challenging. We sought to investigate the gene expression profile of IPF vs. NSIP We used microarray to identifiy the gene expression profiles in patients with IPF and NSIP, mixed IPF/NSIP histologic pattern and normal controls.

Altered mRNA profile in testis of patients with“secondary idiopathic non-obstructive azoospermia”

Project description:Background: Non-obstructive azoospermia (NOA) is the most severe form of male infertility. Currently known causative factors, including congenital and several acquired causes can only account for approximately 30% of NOA cases. Causes for most patients with NOA remains unclear, which were known as idiopathic NOA (iNOA). However, whether iNOA is congenital defects or acquired abnormalities is a confusing problem due to the delayed diagnosis of this frustrating situation until childbearing age. Materials and Methods: In this study, several patients who were diagnosed as iNOA at this stage, but with a history of natural conceptions with female before were enrolled and defined as “secondary idiopathic NOA”. As little was known about these cases, we performed the mRNA expression profiling by Next-generation sequencing (NGS) in this three patients and other three patients with obstructive azoospermia (OA) as controls. Results: A series of mRNAs were found to be altered in testicular tissues between “secondary idiopathic NOA” and controls, including 6028 downregulated and 3402 upregulated mRNAs. GO analysis and KEGG analysis revealed a range of GO and KEGG terms, such as cellular process involved in reproduction, protein digestion and absorption, etc. Conclusion: Overall, this study introduces a novel classification called “secondary idiopathic NOA” in iNOA. We provide a global view of the altered mRNAs involved in spermatogenetic failure in these cases.
