Abstract
Doxorubicin is an extensively applied anti-cancerous drug since 1950's and its usage is constrained because of its accumulation in a non-cancerous organ. Many studies have proven that doxorubicin causes reproductive toxicity depends on its dosage, particularly due to increased oxidative stress and apoptosis. A number of the researches have been carried out concerning its prevention. But there is a need to recognize the mechanism at the back of its toxicity to get better and improved method of treatment. To clarify the feasible mechanism of doxorubicin-mediated reproductive toxicity in rats, we have administrated doxorubicin at distinct dosages inclusive of low dosage (male rats that are at 230-250 g acquired cumulatively 1.5 mg/kg; ip; once per week for five weeks) and high dosage (male rats which are at 230-250 grams obtained cumulatively 15 mg/kg; ip; once every week for five weeks). Doxorubicin decreases antioxidant level such as GSH, Cu/Zn SOD, Mn SOD both in serum and testes. Increased oxidative stress is considered via elevated MDA level both in serum and testes. The level of ROS is measured via the DCFDA method in testes. Apoptosis become found through DNA fragmentation assay and quantification of Caspase 3, Caspase 9, Bcl2 and Cytochrome C. Doxorubicin mediated oxidative stress and apoptosis in testicular milieu is through deregulation of Nrf2, PGC-1α, AHR, ARNT, PXR, SUMO-1, UCP2, UCP3, ANX A5, Caspase 3, Caspase 9, Bcl2, Cytochrome C, GR, and GPX. In end, doxorubicin-mediated oxidative stress and apoptosis is through diverse transcriptional factors and genes with respect to decreased antioxidant level, augmented ROS level and Annexin A5 in the testicular milieu.

Knockout of BRD7 results in impaired spermatogenesis and male infertility. Sci Rep 2016; 6:21776. [PMID: 26878912 PMCID: PMC4754950 DOI: 10.1038/srep21776] [Citation(s) in RCA: 34] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2015] [Accepted: 02/01/2016] [Indexed: 12/31/2022] Open
Abstract
BRD7 was originally identified as a novel bromodomain gene and a potential transcriptional factor. BRD7 was found to be extensively expressed in multiple mouse tissues but was highly expressed in the testis. Furthermore, BRD7 was located in germ cells during multiple stages of spermatogenesis, ranging from the pachytene to the round spermatid stage. Homozygous knockout of BRD7 (BRD7−/−) resulted in complete male infertility and spermatogenesis defects, including deformed acrosomal formation, degenerative elongating spermatids and irregular head morphology in postmeiotic germ cells in the seminiferous epithelium, which led to the complete arrest of spermatogenesis at step 13. Moreover, a high ratio of apoptosis was determined by TUNEL analysis, which was supported by high levels of the apoptosis markers annexin V and p53 in knockout testes. Increased expression of the DNA damage maker λH2AX was also found in BRD7−/− mice, whereas DNA damage repair genes were down−regulated. Furthermore, no or lower expression of BRD7 was detected in the testes of azoospermia patients exhibiting spermatogenesis arrest than that in control group. These data demonstrate that BRD7 is involved in male infertility and spermatogenesis in mice, and BRD7 defect might be associated with the occurrence and development of human azoospermia.

Deregulation of sertoli and leydig cells function in patients with Klinefelter syndrome as evidenced by testis transcriptome analysis. BMC Genomics 2015; 16:156. [PMID: 25879484 PMCID: PMC4362638 DOI: 10.1186/s12864-015-1356-0] [Citation(s) in RCA: 44] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2014] [Accepted: 02/19/2015] [Indexed: 01/01/2023] Open
Abstract
Background Klinefelter Syndrome (KS) is the most common abnormality of sex chromosomes (47,XXY) and represents the first genetic cause of male infertility. Mechanisms leading to KS testis degeneration are still not completely defined but considered to be mainly the result of germ cells loss. In order to unravel the molecular basis of global testis dysfunction in KS patients, we performed a transcriptome analysis on testis biopsies obtained from 6 azoospermic non-mosaic KS patients and 3 control subjects. Results The analysis found that, compared to controls, KS patients showed the differential up- and down-expression of 656 and 247 transcripts. The large majority of the deregulated transcripts were expressed by Sertoli cells (SCs) and Leydig cells (LCs). Functional analysis of the deregulated transcripts indicated changes of genes involved in cell death, inflammatory response, lipid metabolism, steroidogenesis, blood-testis-barrier formation and maintenance, as well as spermatogenesis failure. Conclusions Taken together, present data highlight the modulation of hundreds of genes in the somatic components of KS patient testis. The increased LCs steroidogenic function together with the impairment of inflammatory pathways and BTB structure, result in increased apoptosis. These findings may represent a critical roadmap for therapeutic intervention and prevention of KS-related testis failure.
