Abstract
Background: The cause of oligoasthenoteratozoospermia (OAT) is unclear. In this original study, we examined OAT patients' sperm using RNA-sequencing and studied the impact of curcumin on gene expression during sperm cryopreservation and freeze-thawing.
Methods: RNA-seq was performed using the Galaxy Europe server in IKHC (Imam Khomeini Hospital Complex), Tehran, Iran in 2023. Sperm samples were collected from 30 OAT patients and 30 healthy volunteers. Sperm parameters were analyzed, and samples were frozen with 20 μM curcumin at -196 °C for one week. Thawed samples were assessed for sperm parameters, and the expression levels of bax, bak, bcl-2, bclw, casp9, apaf-1, SOD, cat, and GPX4 genes were measured using RT-PCR.
Result: RNA-seq analysis showed increased expression of NANOS1, HSPA6, and ALOXE3 genes, while BHLHE41, Hey1, and PPM1D genes were down-regulated in OAT patients' sperm. Curcumin (20 μM) effectively preserves sperm parameters and motility during cryopreservation in healthy subjects and in OAT patients in particular. Cryopreserved sperm from both OAT patients and healthy individuals exhibited reduced expression of pro-apoptotic genes, increased expression of anti-apoptotic genes, and elevated levels of SOD and GPX4 genes.
Conclusion: Altered expressions of NANOS1, HSPA6, ALOXE3, BHLHE41, Hey1, and PPM1D genes likely contribute to OAT development. Additionally, curcumin protects sperm parameters during cryopreservation for both healthy individuals and OAT patients.
期刊介绍：
Iranian Journal of Public Health has been continuously published since 1971, as the only Journal in all health domains, with wide distribution (including WHO in Geneva and Cairo) in two languages (English and Persian). From 2001 issue, the Journal is published only in English language. During the last 41 years more than 2000 scientific research papers, results of health activities, surveys and services, have been published in this Journal. To meet the increasing demand of respected researchers, as of January 2012, the Journal is published monthly. I wish this will assist to promote the level of global knowledge. The main topics that the Journal would welcome are: Bioethics, Disaster and Health, Entomology, Epidemiology, Health and Environment, Health Economics, Health Services, Immunology, Medical Genetics, Mental Health, Microbiology, Nutrition and Food Safety, Occupational Health, Oral Health. We would be very delighted to receive your Original papers, Review Articles, Short communications, Case reports and Scientific Letters to the Editor on the above mentioned research areas.
