Summary: This study evaluated the effect of DAC on DNA methylation and the immune system of pearl oysters. The results showed that DAC decreased global DNA methylation level and activated immune-related genes, leading to an improvement in humoral immunity. These findings contribute to a better understanding of the mechanism underlying DNA methylation in immune regulation.

Summary: This study characterized the FAD gene in P. f. martensii and found that Pm Delta 5FAD plays an important role in regulating inflammation. Functional analysis showed that Pm Delta 5FAD has Delta 5-desaturation activity towards PUFA substrates and its expression level significantly increases on day 1 after grafting operation.

Summary: This study analyzed the function and regulatory role of a novel microRNA miR-63 in the immune response of pearl oysters. The results showed that the expression of this microRNA increased after pathogen stimulation and overexpression of it resulted in decreased activity of immune and antioxidant enzymes in the serum.

Summary: This study used metabolomic and transcriptomic approaches to analyze the metabolic and transcript changes in different larval stages of Pinctada fucata martensii, identifying key pathways and understanding the molecular and metabolic mechanisms underlying larval metamorphosis. The results showed significant differences in metabolites and gene expression between different larval stages, particularly in pathways associated with neurotransmitters. This integrated analysis provides valuable insights into the process of larval settlement and metamorphosis in P. f. martensii.

Summary: Metabolomic analysis of pearl oysters before and after transplantation identified 35 significantly differential metabolites involved in immune response, with pathways such as sphingolipid metabolism and D-glutamine metabolism. Upregulation of nAChRs and ACh after transplantation may function through inhibiting the NF-kappa b signal pathway, potentially improving the survival rate of pearl oysters.

Summary: In this study, transcriptomic and proteomic analyses were used to investigate the gene/protein expression patterns in Pinctada fucata martensii 12 hours after nucleus implantation. The results revealed differential expression genes and proteins, as well as enriched signaling pathways, indicating their importance in the response to nucleus implantation. This research provides insights into the molecular mechanisms involved in pearl biosynthesis and the biology of bivalve molluscs.

Summary: This study demonstrated that mycophenolate mofetil (MMF) can significantly increase pearl retention rates in pearl oysters without affecting survival rates and high-quality pearl rates. Molecular and histological analysis indicated that MMF effectively regulates immune response induced by transplantation and improves the performance of pearl production.

Summary: A comprehensive genomic analysis identified 123 H4 genes from nine species, with only two members in the genome of pearl oyster Pinctada fucata martensii. Evolution analysis revealed that this contraction occurred after the divergence of P. f. martensii and Crassostrea gigas. The two H4 genes showed differences in tissue expression patterns and immune responses.

Summary: The study found that high abundance of microplastics in the ocean negatively affects the formation of shells and pearls, while low-quality round pearls contain less microplastics. During the biomineralization process of bivalves, microplastics become embedded in shells and increase the expression of biomineralization-related genes.

Summary: This study investigated the growth of Chilean strains of Heterosigma akashiwo and Pseudochattonella verruculosa under different temperature and salinity conditions, revealing optimal growth rates and mechanisms for these two species. The research also demonstrated the varying effects of these microalgae on fish cells and attributed the recent large blooms in Chile to differences in climate conditions and physiological traits of the two species.
