Unsatisfactory results of in vitro maturation (IVM) impair the development, survival and implantation of the embryo. Insulin-like growth factor 1 (IGF-1) is widely used in IVM, but its efficacy is controversial and consistent evidence is lacking. To investigate the efficacy of IGF-1 in IVM, we conducted a systematic review and meta-analysis on bovine oocytes competence and subsequent embryonic development.

Taurine deficiency is a driver of aging, however the mechanisms by which taurine regulates postovulatory oocyte aging (POA) remain an unanswered question. Here, we used differential gene expressions and functional enrichment analysis of transcriptomes to determine transcriptional dynamics in POA. Transcriptional conservation between mouse and pig was determined by comparative analysis of transcriptomes.

Polyspermy is a type of abnormal fertilization that would increase the risk of embryonic death and hence reduced female fecundity. To avoid this occurrence, mammalian oocytes develop the complicated mechanisms of blocks to polyspermy. Our previous study discovered that transglutaminase 2 (Tgm2) is a newly identified molecule responsible for the post-fertilization block to sperm penetration through zona pellucida (ZP) and polyspermy in mice.

RNA modifications play crucial roles in immune system development and function, with dynamic changes essential for diverse cellular processes. Innovative profiling technologies are invaluable for understanding the significance of these modifications in immune cells, both in healthy and diseased states. This review explores the utility of such technologies in uncovering the functions of RNA modifications and their impact on immune responses.

Ruminant species are important to human society due to their ability to convert human-inedible sources of energy and protein to human-edible food. Greater efficiency of meat and milk production will require the management of the complex reproductive biology of many cattle with a limited capacity and limited budget within a smaller, hotter, and more climatically erratic land area. The over-riding drivers of new reproductive technologies in North America will be smaller economic margins, larger herd size, fewer agricultural workers per farm, and a greater reliance on automation to offset the reduced agricultural labor force.
