Summary: The study provides detailed transcriptome data on the ovarian maturation cycle in M. nipponense, identifying key genes related to vitellogenin hydrolysis and oocyte excretion. This information can serve as an important reference for genomics, molecular biology, physiology, and population genetics of M. nipponense and other crustaceans, aiding in addressing the issue of rapid ovarian maturation in M. nipponense.

Summary: Inhibition of oocyte maturation is a mechanism by which chemical stressors can impair fecundity of female fishes. The study aimed to develop an assay to evaluate oocyte maturation disruption by chemical stressors in Japanese medaka. Results showed that TBCO inhibited oocyte maturation and decreased fecundity in Japanese medaka, and in vitro assays of oocyte maturation might be predictive of fecundity in this species.

Summary: This study characterized the sex-specific splicing forms of the Ae. albopictus dsx gene and identified direct target genes of DSX in adult females. The results suggest that direct regulation of Aalbdsx on VgR is essential for ovarian development in Ae. albopictus, providing insight into the evolutionarily conserved role of dsx in sexual differentiation and potential molecular targets for vector control.

Summary: This study investigated ovary development and oogenesis in Chinese hook snout carp, as well as cloned full-length cDNA sequences of two vtg genes from the liver. The expression of Ob-vtgAo1 and Ob-vtgC mRNA was significantly higher in the liver of O. bidens than in other tissues, especially during Stage IV ovaries when oocytes were filled with yolk granules.

Summary: Field investigation revealed that alterations in water temperatures, even as little as a 2-3 degrees C difference due to reservoir operations, were associated with a reduction in fish spawning. However, the underlying physiological mechanism remains unclear. In order to investigate the effects of altered water temperature on fish ovary development, experiments were conducted on Coreius guichenoti at three different temperatures. The results showed that the DFO had a stronger response to changes in lower temperature conditions compared to higher temperature conditions. Upregulation of certain genes related to vitellogenin receptors was observed at the normal temperature, indicating that it facilitated the development of fish ovary. Other temperature-sensitive genes were found to be associated with cell division and material transport. The findings provide valuable insights for reservoir operations and fish conservation measures in the face of river damming and climate change.

Summary: The study assessed the reproductive maturation of meagre reared in sea cages under routine farming conditions. It was observed that meagre males and females, produced in hatcheries and reared in sea cages, are able to spontaneously produce and release gametes. This suggests that meagre reproduction under commercial conditions could expand meagre aquaculture production, which currently relies on limited fingerling production by a select few hatcheries.

Summary: This study in a mouse model revealed that early folliculogenesis requires a minimum of two weeks, with different stages showing specific characteristics such as oocyte size at Type 4-5 stage and theca folliculi formation at PD10-12. The study also highlighted the importance of the PD22-23 period for studying puberty initiation, providing valuable insights into the biological events of this process.

Summary: EXOSC10 is a catalytic subunit of the nuclear RNA exosome that plays a crucial role in oogenesis. Through specific inactivation of Exosc10, researchers found that Exosc10cKO(Gdf9) female mice became infertile due to oocyte degeneration and a lack of follicles in the ovaries. Proteome analysis also revealed EXOSC10-dependent proteins involved in meiotic cell cycle progression and oocyte maturation. These findings highlight the essential role of EXOSC10 in oogenesis and its potential as a model for primary ovarian insufficiency in humans.

Summary: The transcription factor BmKRP was identified as a new mediator of 20E regulation of B. mori oogenesis. The study suggests that induction of BmKRP by 20E regulates BmKr-h1 expression, which then induces BmVgR expression to facilitate Vg uptake and oogenesis. Experimentally blocking BmKRP led to suppressed transcription of BmKr-h1 and BmVgR, resulting in arrested oogenesis.

Summary: In recent years, there has been an increasing focus on the study of circular RNAs (circRNAs) in noncoding RNAs. While circRNAs are abundant in mammalian studies, research in lower vertebrates has been lacking. In this study, a circRNA called circPlce1 was found to be related to the innate immune response in Miichthys miiuy (miiuy croaker). Experimental results showed that circPlce1 could promote the production of antiviral genes and inflammatory response. It was also observed that circPlce1 can promote cell proliferation and improve cell viability. The study provides a foundation for understanding the biological function of circRNAs in the innate immune response in teleost fish.

Summary: The increasing demand for fish protein has led to a rise in fish production through aquaculture and wild capture. Pathogen infections in hatcheries and grow-out ponds have resulted in reduced productivity and economic losses for farmers. Utilizing omics datasets and systems biology approaches can help scientists understand complex host-pathogen interactions and identify new targets for combating diseases in aquaculture. Various omics approaches such as genomics, transcriptomics, proteomics, and metabolomics are valuable tools in developing treatment and prevention strategies to address aquaculture diseases caused by microbial infections.
