Testis Transcriptome Modulation in Klinefelter Patients with Hypospermatogenesis. Sci Rep 2017; 7:45729.

Abstract
The main genetic cause of male infertility is represented by the Klinefelter Syndrome (KS), a condition accounting for 3% of all cases of infertility and up to15% of cases of azoospermia. KS is generally characterized by azoospermia; approximately 10% of cases have severe oligozoospermia. Among these, the 30-40% of patients show hypospermatogenesis. The mechanisms leading to adult testis dysfunctions are not completely understood. A microarray transcriptome analysis was performed on testis biopsies obtained from three KS patients with hypospermatogenesis and three control subjects. KS testis showed a differential up- and down-regulation of 303 and 747 transcripts, respectively, as compared to controls. The majority of down-regulated transcripts were involved in spermiogenesis failure and testis morphological defects, whereas up-regulated genes were responsible for testis apoptotic processes. Functional analysis of the transcriptionally altered genes indicated a deregulation in cell death, germ cell function and morphology as well as blood-testis-barrier maintenance and Leydig cells activity. These data support a complex scenario in which spermatogenic impairment is the result of functional and morphological alterations in both germinal and somatic components of KS testis. These findings could represent the basis for evaluating new markers of KS spermatogenesis and potential targets of therapeutic intervention to preserve residual spermatogenesis.

Association of genetic variants in SOHLH1 and SOHLH2 with non-obstructive azoospermia risk in the Chinese population. Eur J Obstet Gynecol Reprod Biol 2014; 184:48-52. [PMID: 25463635 DOI: 10.1016/j.ejogrb.2014.11.003] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2014] [Revised: 11/01/2014] [Accepted: 11/11/2014] [Indexed: 11/18/2022]
Abstract
OBJECTIVE Spermatogenesis and oogenesis specific basic helix-loop-helix 1 (SOHLH1) and spermatogenesis and oogenesis specific basic helix-loop-helix 2 (SOHLH2) play essential roles for both spermatogenesis and oogenesis. The aim of this study was to evaluate the association of SOHLH1 and SOHLH2 single nucleotide polymorphisms (SNPs) with non-obstructive azoospermia (NOA) in the Chinese population. STUDY DESIGN In this study, we assessed 7 single nucleotide polymorphisms (SNPs) of SOHLH1 and SOHLH2 with Sequenom iplex technology in 361 NOA cases and 368 fertile controls. RESULTS We found that the SNPs rs1328626 and rs6563386 of SOHLH2 were significantly associated with NOA risk, of which, a protective effect of minor allele T of rs1328626 on NOA (P = 0.038, odds ratio [OR] = 0.799, 95% confidence interval [CI] = 0.645-0.988) and a significantly increased risk of the SNP rs6563386 with the minor allele G to NOA (P = 0.029, OR = 1.402, 95% CI = 1.034-1.9) were observed, respectively. Our data indicated that the haplotype GC of the variants rs1328626 and rs6563386 conferred a significantly increased risk of NOA (P = 0.031, OR = 1.397, 95% CI = 1.031-1.895). Moreover, we found the genotype distribution of rs1328641 was significantly associated with testes volume in the NOA patients (P = 0.022). CONCLUSIONS The polymorphisms rs1328626 and rs6563386 of the SOHLH2 gene would be the genetic risk factors for NOA in the Chinese population. The SNP rs1328641 might influence testes development in the NOA patients.
