Abstract
Leydig cells play a crucial role in male reproductive physiology, and their dysfunction is often associated with male infertility. Hypoxia negatively affects the structure and function of Leydig cells. This study aimed to investigate the impact of melatonin on the c-Jun N-terminal kinase (Jnk), P38, and extra-cellular signal-regulated kinases 1 and 2 (Erk1/2) mitogen-activated protein kinase (MAPK) signaling pathways in TM3 mouse Leydig cells under hypoxia induced by cobalt (II) chloride (CoCl2). The TM3 cell line was utilized as a subject of research, and 100 μM CoCl2 was employed to induce hypoxia. Following the addition of 10.00 ng mL-1 melatonin, quantitative reverse transcription-polymerase chain reaction and western blot analyses were conducted to assess the gene expression and protein level of Jnk, p38, and Erk1/2, while enzyme-linked immunosorbent assay was used to measure testosterone secretion. The results showed that melatonin significantly increased testosterone production in the CoCl2 + melatonin group compared to the CoCl2-treated group. Furthermore, melatonin elevated both the protein level and mRNA expression of Erk1/2, Jnk, and p38 genes in the CoCl2 + melatonin group compared to the CoCl2 group. In conclusion, melatonin activated the Jnk, p38, and Erk1/2 MAPK signaling pathways and enhanced testosterone production in the presence of CoCl2 in TM3 cells.
