Summary: Shrimp reproduction is controlled by various factors, and this study identified and studied putative gonad stimulating factors (GSFs) from the thoracic ganglia of adult female Fenneropenaeus merguiensis. A total of 3224 putative GSFs were identified, with 376 showing differential expression during ovarian development. The Indian hedgehog gene (FmIHH) was confirmed as a crucial GSF in vitellogenesis and was found to regulate sugar uptake during ovarian development.

Summary: A novel missense mutation (I423T) in the FSHR second transmembrane domain was identified in a woman with primary ovarian failure, leading to impaired receptor expression and signaling. Meanwhile, the D408Y mutation severely affected membrane expression and signal transduction. Molecular dynamics simulations showed important disruptions in both mutant FSHRs, explaining the differences in expression levels, signaling, and phenotypic expression between I423T and D408Y mutant FSHRs.

Summary: In this study, silencing of the VIH gene alone or in combination with the MIH gene successfully induced ovarian maturation and development in females of Macrobrachium rosenbergii, with more pronounced effects in mature individuals. Additionally, the dsRNA used to silence VIH also affected the expression of MIH, albeit with a delay compared to the dsRNA targeting both VIH and MIH simultaneously.

Summary: Glycoprotein hormones are heterodimers consisting of a common alpha subunit and a specific beta subunit. While they typically act by activating specific receptors, individual subunits have been found to elicit responses in the absence of the receptor. These subunits play important roles in prolactin production, placentation, cancer development, and are related to cysteine-knot growth factors evolutionarily.

Summary: Vitellogenesis-inhibiting hormone (VIH) negatively regulates reproduction in shrimp, and transcriptional silencing of Liv-SGP-G was successfully achieved with dsRNA injections. Although the treatment did not promote ovarian maturation, it was the first report of co-transcriptional repression of Liv-SGP-G using dsRNAs for homologous genes. This study indicates that subadult shrimp can respond to transcriptional silencing techniques.

Summary: The reproductive activity of captive dusky groupers was evaluated using non-lethal tools. The plasma profile of gonadal steroids and follicle-stimulating hormone (FSH) was measured, and the effects of human Chorionic Gonadotropin (hCG) and 17 beta-estradiol (E2) implants on vitellogenesis were investigated. Results showed that captivity had a negative impact on vitellogenesis in E. marginatus.

Summary: The study found that short-acting testosterone preparations have less suppression on FSH and LH compared to longer-acting formulations, indicating potential differences in the impact on semen parameters and fertility. Further clinical trial data is needed to confirm these findings.

Summary: Studies have shown that MKRN3 is an inhibitor of GnRH secretion and its loss of function is the most common genetic cause of central precocious puberty in humans. The expression pattern of Mkrn3 in gonads during sexual development was investigated and it was found to be sexually dimorphic between male and female gonads. Mkrn3 is expressed primarily in the interstitial compartment of the testes and its expression increases after puberty and is responsive to luteinizing hormone/hCG stimulation.

Summary: This study evaluated the growth, survival, and oogenesis of C. viridis before and after 17 beta-estradiol (E-2) treatments. The results showed that E-2 treatment significantly affected sex change in males, but had minimal impact on the growth and survival rate of the fish. Furthermore, the availability of vitellogenic females after induced sex change was found to be unpredictable.

Summary: A family of leucine-rich-repeat-containing G-protein-coupled receptors (LGRs) can mediate diverse physiological responses when combined with their ligands. LGRs are present in all metazoan animals. In humans, the LGR ligands are glycoprotein hormones (GPHs), such as hCG, luteinizing hormone, hFSH, and hTSH. These hormones are composed of α3 heterodimers of cystine-knot protein chains. We have determined the structure of a hormone from Caenorhabditis elegans, which is similar in structure to vertebrate GPHs. Known structures and AlphaFold models provide representatives for the molecular evolution of LGR ligands.

Summary: Coastal organisms, such as grass puffers, synchronize their reproduction with the lunar cycle. The secretion of prostaglandin E2 (PGE2) into the seawater during spawning triggers the trembling behavior of grass puffers, which is synchronized with the lunar-regulated beach-spawning behavior. The semilunar transcription factor CCAAT/ enhancer-binding protein d (cebpd) plays a role in the transcription regulation of gonadotropin-releasing hormone 1 (gnrh1) in grass puffers.

Summary: This study investigated the transcriptomic changes that occur in the ovary of flathead grey mullet during rGths-induced vitellogenesis. The analysis revealed that more genes were upregulated than downregulated as vitellogenesis progressed. The application of rFsh and rLh induced different stages of ovarian development and enriched specific molecular pathways.

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.

Summary: This study developed a centrifugal microfluidic chip with on-chip RPA to detect five pathogenic microorganisms. The chip enabled the parallel analysis of six genetic markers from a single sample and allowed for the highly automated detection of multiple samples. Compared with PCR and DNA sequencing, the on-chip RPA assay showed high sensitivity and specificity for detecting multiple pathogens in shrimp aquaculture.
