Potential biomarkers tah could help to determine the prognosis of azoospermia treatment

ABSTRACT: We analyzed gene expression profiles of human testicular biopsies in men with idiopathic nonobstructive azoospermia who underwent therapy with hCG/rFSH. Using new generation oligonucleotide microarray platform GeneChip® Human Gene 1.0 ST, we identified genes which could be potential prognostic biomarkers of azoospermia treatment.

Potential biomarkers tah could help to determine the prognosis of azoospermia treatment

Project description:We analyzed gene expression profiles of human testicular biopsies in men with idiopathic nonobstructive azoospermia who underwent therapy with hCG/rFSH. Using new generation oligonucleotide microarray platform GeneChipÂ® Human Gene 1.0 ST, we identified genes which could be potential prognostic biomarkers of azoospermia treatment. We analyzed 6 testicular biopsy samples with Affymetrix Human Gene 1.0 ST microarrays. 3 of them were obtained from patients with NOA, who positively responded to hormonal therapy and 3 non-respoders.

Potential biomarkers of non-obstructive azoospermia identified in microarray gene expression analysis

Project description:We analyzed gene expression profiles of human testicular biopsies in men with idiopathic nonobstructive azoospermia. Using new generation oligonucleotide microarray platform GeneChipM-BM-. Human Gene 1.0 ST, we identified genes which could be potential biomarkers of azoospermia and molecular indicators that could determine a particular stage of impaired spermatogenesis. Thus, we shed light on genes which were had so far been weakly characterized and which were had never related to infertility before. These studies also included the comparative analysis of the hierarchical clustering of gene expression profile with histopathological data provided for azoospermic patients. We analyzed 31 testicular biopsy samples with Affymetrix Human Gene 1.0 ST microarrays. 27 of them were obtained from patients with various types of NOA and 4 with normal spermatogenesis.

TMT-based proteomics and phosphoproteomics analysis of proteome changes in seminal plasma extracellular vesicles of azoospermia

Project description:The proteome and phosphoproteomics changes were quantified in seminal plasma extracellular vesicles among healthy individuals with normal sperm, nonobstructive azoospermia and obstructive azoospermia using TMT 10-plex by LC-MS/MS.

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.

In situ transcriptomic analysis of spermatocytes in non-obstructive azoospermia reveals senescence-like states in arrested spermatocytes

Project description:To investigate in situ transcriptome of spermatocytes in non-obstructive azoospermia , we microdissected spermatocytes in formalin-fixed paraffin-embedded testicular biopsy tissue from two types of non-obstructive azoospermia and obstructive azoospermia as a control, and then constructed cDNA libraries based on Smart-3SEQ method.

Transcription profiling of testis biopsies to investigate testis developmental gene expression in cryptorchid boys at risk of azoospermia

Project description:Despite timely and successful surgery, 32% of patients with bilateral and 10% with unilateral cryptorchidism will develop azoospermia. Cryptorchid boys at risk of azoospermia display a typical testicular histology of impaired mini-puberty at the time of the orchidopexy. During mini-puberty increased gonadotropin and testosterone secretion stimulate transformation of gonocytes into Ad spermatogonia. In azoospermia risk group this transformation is to a great extent impaired. This study aimed to analyze data on whole genome expression signatures of undescended testes at risk of developing azoospermia. Twenty-three testicular biopsies from 22 boys were analyzed (19 testes from 18 boys with cryptorchidism) and 4 contralateral descended testes from patients with testicular agenesis. Expression profiling identified 483 genes not or under-expressed in the azoospermia risk group compared with the control and LAZR groups. Annotated loci were associated with spermatogenesis. Other significant genes were cellular defense response genes and hormone controlled loci involved in spermatogenesis. Some genes transcribed in normal adult meiotic and post-meiotic germ cells are activated in healthy juvenile Ad spermatogonia. Thus, molecular events initiating the testicular expression program at the onset of puberty and maintaining it during adulthood occur very early in prepubertal testes. This molecular event is to a great extent impaired in HAZR group lacking Ad spermatogonia (stem cells for spermatozoa) indicating impaired mini puberty.

Comparative proteomics analysis of FFPE testicular tissue from men with obstructive and non-obstructive azoospermia

Project description:The project aimed to compare testicular proteomes from patients with obstructive and non-obstructive azoospermia in order to identify molecular signatures involved in spermatogenesis as well to identify candidate biomarkers for discriminating between different types of azoospermia. The samples used in this study were formalin fixed paraffin embedded (FFPE) testicular tissues obtained by biopsy from men with clinical diagnosis of azoospermia. Samples were grouped according to the histopathological report in 3 groups: 1) Spermatogenesis (obstructive azoospermia), 2) Hypospermatogenesis and 3) Sertoli cell only syndrome (SCO). Patients were aged 31–46 years with no differences among groups regarding age (Median age (Hypospermatogenesis) =35; Median age (SCO) =34 and Median age (Spermatogenesis) =39). Each group had 9 samples or 27 samples in total were used for the comparative proteomics analysis by label-free data-independent LC-MS/MS.

The gene expression analysis of paracrine/autocrine factors in patients with spermatogenetic failure compared to normal spermatogenesis

Project description:The role of paracrine/autocrine factors in inflammation, immune response and tumor development is well established. There is also an evidence that some of the cytokines there involved may participate in the regulation of the male gonads. However, their involvement in pathogenesis of male infertility has not been well defined yet. The aim of the present study was to examine the expression levels of IL-1 family members, IL-6, IL-10, TNF family, SCF and c-kit in infertile patients with idiopathic non-obstructive azoospermia (NOA) compared to men with normal spermatogenesis We analyzed testicular biopsy specimens obtained from 16 patients with non-obstructive azoospermia (NOA) and 4 with normal spermatogenesis using Affymetrix Human Gene 1.0 ST.
