Project description:Purpose: To compare the transcriptome profiles (RNA-seq) of cultured human epididymis cells and tissue from the caput, corpus and cauda regions of the human epididymis. Methods: Human epididymis tissue was obtained with Institutional Review Board approval from 3 patients (UC05, UC06, UC09, range: 22 - 36 years) undergoing inguinal radical orchiectomy for a clinical diagnosis of testicular cancer. None of the epididymides had extension of the testicular cancer. The three anatomical regions: caput, corpus and cauda, were separated and segments of each snap frozen. Adult human epididymis epithelial (HEE) cultures were also established from tissue. RNA was extracted from both tissue and cultured HEE cells and RNA-seq libraries prepared (TruSeq RNA Sample Preparation Kit v2, Low-Throughput protocol, Illumina). Libraries were sequenced on Illumina HiSeq2500 machines. Data were analyzed using TopHat and Cufflinks. Results: Libraries generated ~19-39 million reads per library from the cells (95-99% mapping to the human genome) and ~14-39 million reads from the tissue samples (84-99% mapped). Raw reads were aligned to the genome with Tophat and gene expression values were processed using Cufflinks as Fragments Per Kilobase per Million mapped fragments (FPKM). FPKM values were subject to principle component analysis, which revealed that though caput, corpus and cauda cell samples respectively from UC05, UC06 and UC09 clustered together. RNA-seq data from the 3 biological replicas (UC05, UC06 and UC09) of caput, corpus and cauda were pooled for further analysis. Cufflinks was used to determine differentially expressed genes (DEGs) between caput, corpus and cauda cells, combined from the 3 donors. The gene expression profiles of corpus and cauda are remarkably similar and both differ from the caput to a similar degree. We identified ~40 genes differentially expressed between corpus and cauda and more than 1600 DEGs between caput and cauda. The DEGs for each comparison (caput and corpus/cauda) were analysed using a gene ontology process enrichment analysis (DAVID, Huang et al., NAR 2009;37:1-13, Huang et al., 2009 Nat Prot 4:44-57). Conclusions: Here we describe an in depth analysis of the gene expression repertoire of primary cultures of epithelial cells and intact tissues from each region of the adult human epididymis. These data will be valuable to decipher pathways of normal epididymis function and aspects of epididymis disease that cause male infertility. RNA-seq was performed on libraries generated from caput, corpus and cauda-derived cultured cells (passage 2 or 3) from 3 donors and on caput, corpus and cauda tissue from 2 of the same donors. Donor age range: 22 - 36 years.

Project description:This study investigated the differential responses of the epididymis and testis to infection with uropathogenic Escherichia coli (UPEC) in adult mice. In contrast to the cauda epididymidis, which exhibited ongoing damage following UPEC-infection, spermatogenic disruption was reversible and the caput epididymidis was largely unaffected. The caput epididymidis is structurally and functionally very different from the cauda, whereas beta-defensins as important epididymal antimicrobial factors are highly expressed in both tissues. The transcriptome of the testis, caput, corpus and cauda epididymidis were analysed in normal, wildtype C57BL/6J mice. Distinct differences in gene signatures were observed between caput and cauda epididymidis, particularly among immune-related genes, whereas corpus and cauda were much more alike. Beta-defensins were found at high levels in both caput and cauda epididymidis, whereas other antimicrobial factors, such as Lipocalin 2 and Lypd8 were found expressed selectively high in the caput epididymidis and hence may play an important role in local protection from bacterial pathogens, including UPEC.

Project description:Epithelial cells are immune sensors and mediators that constitute the first line of defense against infections. Using the epididymis, a model for studying tubular organs, we uncovered a novel and unexpected role for professional proton-secreting 'clear cells' in sperm maturation and immune defense. The epididymal epithelium participates in the maturation of spermatozoa via the establishment of an acidic milieu and transfer of proteins to sperm cells, a poorly characterized process. We show that proton-secreting clear cells express mRNA transcripts and proteins that are acquired by maturing sperm, and that they establish close interactions with luminal spermatozoa via newly described 'nanotubes'. Mechanistic studies show that injection of bacterial antigens in vivo induces chemokine expression in clear cells, followed by macrophage recruitment into the organ. Injection of an inflammatory intermediate mediator (IFN-?) increased Cxcl10 expression in clear cells, revealing their participation as sensors and mediators of inflammation. The functional diversity adopted by clear cells might represent a generalized phenomenon by which similar epithelial cells decode signals, communicate with neighbors and mediate mucosal immunity, depending on their precise location within an organ.

Project description:Analysis of the gene expression pattern in the caput, corpus and cauda epididymides of three donors of 26-50 years of age with no medical pathologies that could affect reproductive function. The data generated in this study demonstrate a region specific gene expression pattern along the human epididymis that seems to coincide with the morphological distinctive features of the excurrent duct. Experiment Overall Design: Epididymides were dissected in caput, corpus and cauda epididymidis from three donors: ages 26, 47, and 50 yrs. Expression profiles were generated on Affymetrix GeneChip U133 Plus 2.0 arrays (9 samples total).

Project description:Following their production in the testis, spermatozoa enter the epididymis to gain their motility and fertilizing abilities. This post-testicular maturation coincides with sperm epigenetic profile changes that influence the progeny outcome. While recent studies underscored the dynamics of small non-coding RNAs in the maturing spermatozoa, little is known regarding sperm methylation changes and their impact at the post-fertilization level. To map out the sperm methylome dynamics, we purified spermatozoa by FACS from the testis and the different epididymal segments (i.e. caput, corpus and cauda) of CAG/su9-DsRed2; Acr3-EGFP transgenic mice. Reduced-Representation Bisulfite Sequencing (RRBS-Seq) performed on DNA from these respective sperm populations indicated that high methylation changes were observed between spermatozoa from the caput vs. testis with 5546 entries meeting our threshold values (q value < 0.01, methylation difference above 25 %). Most of these changes were transitory during epididymal sperm maturation according to the low number of entries identified between spermatozoa from cauda vs. testis.

Project description:Viral infections of the epididymis are associated with epididymitis, which damages the epithelium and impairs fertility. We showed previously that innate immune response genes were differentially expressed in the corpus and cauda region of the human epididymis in comparison to the caput. Here we investigate the antiviral defense response mechanisms of human epididymis epithelial (HEE) cells. Toll-like receptor (TLR) 3 and retinoic acid-inducible gene I (RIG-I)- like receptors (RLRs) are enriched in HEE cells from the corpus and cauda region. Furthermore, corpus and cauda HEE cells show an enhanced response to antiviral ligands (poly(I:C) and HSV-60), as shown by increased IFN-β mRNA expression and secretion of IFN-β. We also show that paired box 2 (PAX2), which was implicated in regulating antiviral response pathways is required for basal expression of the DNA sensor, Z-DNA binding protein (ZBP1) and type I interferon, in caput but not in cauda cells.
