Objective: To investigate whether long non-coding RNA (lncRNA) Gm8097 (LncGm8097) is associated with male infertility.

Methods: The expression and bilogical role of LncGm8097 were investigated.

Results: LncGm8097 expression was down-regulated in the testis tissues with moderate and severe hypospermatogenesis compared with those with normal spermatogenesis and mild hypospermatogenesis (p<0.

Objective: To investigate the expression of phosphoglycerate mutase 1 (PGAM1) in the mouse testis after exposure to single heat stress (SHS).

Methods: We randomly assigned 32 C57 male mice to an SHS (n = 16) and a control group (n = 16), the former bathed in water at 43 ℃ and the latter at 25 ℃ for 15 minutes. At 1 and 7 days after exposure, we harvested the testicular tissue for observation of the morphological changes of testicular cells by HE staining and determination of the location and expression of the PGAM1 protein by immunohistochemistry and Western blot.

Objective: To investigate the expression of phosphoribosyl pyrophosphate synthase 2 (PRPS2) in the human testis and its clinical significance.

Methods: Using quantitative real-time PCR (qRT-PCR) and immunohistochemistry, we detected the expression of PRPS2 mRNA in the testis tissue of the men with normal spermatogenesis or mile, moderate or severe hypospermatogenesis (HS) and that of the PRPS2 protein in the testicular biopsy tissue of 67 adult males. Then, we analyzed the relationship of the PRPS2 expressions with the testicular histological types and clinical parameters of the subjects.

Phosphoglycerate mutase 1 (PGAM1) is reported to be involved in spermatogenic dysfunction. However, the association between PGAM1 and busulfan‑induced hypospermatogenesis and spermatogenic cell apoptosis remains unclear. The aim of the current study was to investigate the association between PGAM1 expression and busulfan‑induced hypospermatogenesis, and the effect of PGAM1 expression on spermatogenic cell apoptosis.

Long non-coding RNA (lncRNA) plasmacytoma variant translocation 1 (PVT1) has been reported to be overexpressed in prostate cancer cells and associated with tumorigenesis in various types of cancer. However, the biological function of lncRNA PVT1 remains largely unknown. The aim of the present study was to investigate the effect of lncRNA PVT1 expression on the proliferation and migration of prostate cancer cells.

Objective: This study is aimed to evaluate the expression of phosphoglycerate mutase 1 (PGAM1) in normal kidney and clear cell renal cell carcinoma (CCRCC), also to evaluate the correlation between PGAM1 expression and clinicopathological features in CCRCC.

Methods: PGAM1 expression was detected in 80 cases of normal kidney and 192 cases of CCRCC by immunohistochemistry (IHC). Meanwhile, PGAM1 expression measured in 8 cases of CCRCC and matched normal kidney tissues by Western blot.

Objective: To investigate the relationship between histopathologic patterns of testicular biopsy and biochemical semen and blood plasma parameters, including neutral a-glucosidase (NAG), fructose, follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone, and prolactin (PRL) in patients with azoospermia.

Materials And Methods: A total of 471 azoospermic patients with definitive pathologic diagnosis were enrolled in this study. Six biochemical parameters, including 2 seminal (NAG and fructose) and 4 blood (FSH, LH, testosterone, and PRL) plasma markers, were analyzed.

Objective: To investigate the correlation between PGAM1 and spermatogenic dysfunction and to evaluate the effect of expression of PGAM1 on the function of germ cells.

Methods: Expression of PGAM1 was detected in 40 cases of infertile males with definite pathological diagnosis and 12 cases of mouse models with spermatogenic dysfunction by immunohistochemistry. Then, cell proliferation, apoptosis, and migration were evaluated when expression of PGAM1 was knocked down by a specific small interfering RNA in GC1 and TM4 cells.
