Homo Sapiens (Human) microRNA 187 Expression Is Dysregulated in Testis of Non-obstructive Azoospermic Men

Abstract
Introduction: MiRNA expression alterations are closely related to growth, proliferation, and cell development. In addition, miR-187 has been found to regulate cellular proliferation. Further, spermatogenesis is a highly complicated process which is regulated through several genes targeted by miRNAs. However, no study has completely addressed the etiology of spermatogenic impairments. Accordingly, the present study examined the expression pattern of Homo sapiens (human) microRNA (hsa-mir-187) in the testicular biopsies of infertile men with non-obstructive azoospermia (NOA) and Sertoli cell-only syndrome (SCOS) subtype in comparison with those with obstructive azoospermia (OA). Methods: Quantitative reverse‐transcription polymerase chain reaction analysis was performed to assess the expression level of hsa-mir-187 using the ΔΔCt method. Results: Our data indicated that hsa-mir-187 was significantly up-regulated in the testis of the SCOS group (P˂ 0.05) in comparison with the OA group. Conclusion: In general, the findings suggest that the differential expression of hsa-mir-187 is linked with male infertility and shed more light on molecular defects that underlie spermatogenic impairments.
