Article Synopsis
- During cryopreservation, many boar sperm cells experience apoptosis due to cold-induced damage, reducing their fertility potential.
- Researchers added varying concentrations of sulforaphane (SFN), a natural antioxidant from cruciferous vegetables, to the freezing extender and found that 5 μM SFN significantly enhanced sperm motility and integrity after thawing.
- SFN works by activating specific cellular pathways that boost antioxidant defenses, effectively reducing sperm apoptosis and improving fertilization ability post-thawing, suggesting a new strategy to improve sperm preservation methods.
The results of artificial insemination (AI) are adversely affected by changes in sperm motility and function throughout the cryopreservation procedure. The proteome alterations of frozen-thawed spermatozoa with various levels of freezability in dairy goats, however, remain largely unknown. To discover differentially expressed proteins (DEPs) and their roles in dairy goat sperm with high or low freezability (HF or LF), we conducted 4D-DIA quantitative proteomics analysis, the results of which are presented in this work.

Using next-generation sequencing, the complete mitogenome sequence of the monotypic species Oliotius oligolepis was obtained, annotated, and characterized. The mitogenomic sequences of Smiliogastrinae fish were compared and analyzed, and a phylogenetic tree was constructed.
