BACKGROUND: Human sperm concentration and motility have dropped dramatically (50%) in the past few decades, and environmental factors are involved in this decline. Long non-coding RNAs (lncRNA) have been discovered to be involved in many cellular processes including spermatogenesis.
OBJECTIVE: This investigation aimed to explore the role of lncRNA8276 in murine spermatogenesis.
MATERIALS AND METHODS: The expression of lncRNA8276 was modified by knockdown or overexpression in mouse testes and spermatogonial stem cells (C18-4 cell line). Sperm quality was determined in the F0 and F1 generations of mice. Furthermore, the underlying mechanisms were studied through gene expression and/or protein expression of spermatogenesis-related genes and cell junction-related genes by different methods.
RESULTS: In the current investigation, we discovered that sperm lncRNA8276 was decreased by NH3 /H2 S in three generations (F0, F1, and F2) of mouse sperm. In vivo testicular knockdown of lncRNA8276 led to a decline in sperm concentration and motility in both F0 (muF0) and F1 (muF1) generations Moreover, knockdown lncRNA8276 decreased the gene and protein levels of important genes related to cell-cell junctions and spermatogenesis. The data were further confirmed in mouse spermatogonia stem cell line C18-4 cells through knockdown of lncRNA8276.
DISCUSSION AND CONCLUSION: Our study suggests that lncRNA8276 may be involved in cell-cell junction formation in the mouse testis to regulate spermatogenesis. It may be a target for the modification of spermatogenesis and male fertility, or male contraception. This investigation offers a potential therapeutic strategy for male infertility.
