Project description:This project contains proteomic profiles of shell matrix proteins (SMPs) from the Iwagaki oyster Crassostrea nippona, covering both life stage-specific shells (D-stage larval and adult shell) and shell microstructure-specific layers (prismatic, foliated, and chalky layers of the adult shell). These datasets were generated to investigate the molecular composition and regulatory mechanisms underlying biomineralized shell formation across developmental stages and shell architectures. The identified proteins provide insights into shell mineralization from both structural and evolutionary perspectives.

Project description:To elucidate the modulatory participation of miRNAs in mollusk biomineralization, we have employed high-throughput sequencing to identify miRNAs of pearl oyster, Pinctada fucata. Our study focused on the miRNA expression profile of the mantle, an organ responsible for shell formation of the oyster. The pearl oysters were cultured in the tank with the maintaining conditions of temperature 19 ℃, PH 8.1 and salinity 33‰ in recirculating seawater.

Project description:This work reports a comprehensive and integrated microstructural, biochemical and proteomics study on the shell matrix of Spondylus gaederopus, the Mediterranean thorny oyster. We investigate the skeletal matrix proteins which are involved in biomineralization and compare the identified Spondylus sequences with other shell proteins, that are publicly available in databases. Using high-resolution liquid chromatography tandem mass spectrometry (LC-MS/MS) we characterized several shell protein fractions, isolated by different bleaching treatments. We identified six shell proteins, which also displayed features and domains typically found in biomineralized tissues, including the prevalence of intrinsically disordered regions. However, many reconstructed peptide sequences (de novo) could not be matched to any known shell proteins and we suggest that these probably represent lineage-specific sequences. The proteomic data implies that Spondylus may have evolved a distinct molecular toolkit for biomineralization.

Project description:Shells of pearl oyster are natural biominerals with remarkable properties and can be repaired after damage, which are regulated by biomacromolcules especially shell matrix proteins (SMPs). Identifying SMPs is critical for further understanding the process. Although proteomic methods have been used to reveal the complex protein mixture in mature shells, the proteomics of repaired shells after shell damage have not been reported before. Here, we studied the SMPs of the repaired shells (prismatic layers) 5-10 days after shell damage in Pinctada fucata by integrating transcriptomics and proteomics and compared the microstructure difference between repaired and mature shells. Although the repaired shells are calcite, similar to mature shells, the microstructure of repaired shells has holes in the center of prisms with irregular and curved edges. In total, we found 49 SMPs from the repaired shells including some proteins only existing in mature nacreous layers. Peroxidase-like protein and beta-N-acetylhexosaminidase may be important players in repaired shells. In addition, they have the capability to affect CaCO3 crystallization process in vitro, altering the packing and reducing the crystallinity of crystals. This study could improve our understanding of shell repair process and lay the foundation for studying SMPs-controlled biomineralization.
