Molecular and functional analysis of PmC1qDC in nacre formation of Pinctada fucata martensii

Fish & Shellfish Immunology, 2020
The C1q-domain-containing (C1qDC) proteins are a family of proteins characterized by a globular C1q (gC1q) domain in their C-terminus which hold the potential function in the shell formation as shell matrix proteins. In this study, a C1qDC protein was identified and characterized in pearl oyster (Pinctada fucata martensii) (PmC1qDC) to explore its ...

Microstructure of iridescence-lacking pearl formed in Pinctada fucata

Journal of Crystal Growth, 2016
Abstract The iridescence-lacking pearl is regarded as a low-quality product because it shows no iridescent color which is generated by the interference of the light reflected at the organic–inorganic boundaries in the regulated interstratification of organic sheets and thin aragonite tablets.

Isolation and Characterization of the N-linked Oligosaccharides in Nacrein from Pinctada fucata

Marine Biotechnology, 2008
We analyzed the structure of the N-linked oligosaccharides enzymatically liberated from the organic matrix (OM) component in the nacreous layer of Japanese pearl oyster: Pinctada fucata. The lectin-blot analysis of the soluble OM after separation by SDS-PAGE, four components, with sizes of approximately 55 kDa, 35 kDa, 25 kDa, and 21 kDa were detected ...

A novel carbonic anhydrase from the mantle of the pearl oyster (Pinctada fucata)

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2006
A novel carbonic anhydrase (CA) has been purified from the mantle of the pearl oyster, Pinctada fucata, by ammonium sulfate precipitation and affinity chromatography. Its molecular mass was determined by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) to be approximately 38 kDa.

Molecular and functional analysis of PmCHST1b in nacre formation of Pinctada fucata martensii

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2018
Keratan sulfate possesses considerable amounts of negatively charged sulfonic acid groups and participates in biomineralization. In the present study, we investigated characteristics and functions of a CHST1 gene identified from the pearl oyster Pinctada fucata martensii (PmCHST1b) which participated in the synthesis of keratan sulfate.

Morphology and classification of hemocytes in Pinctada fucata and their responses to ocean acidification and warming

Fish & Shellfish Immunology, 2015
Hemocytes play important roles in the innate immune response and biomineralization of bivalve mollusks. However, the hemocytes in pearl oysters are poorly understood. In the present study, we investigated the morphology and classification of hemocytes in the pearl oyster, Pinctada fucata.

Characteristics of biogenic calcite in the prismatic layer of a pearl oyster, Pinctada fucata

Micron, 2010
The fine structure of the calcite prism in the outer layer of a pearl oyster, Pinctada fucata, has been investigated using various electron beam techniques, in order to understand its characteristics and growth mechanism including the role of intracrystalline organic substances.

Serum immune response of pearl oyster Pinctada fucata to xenografts and allografts

Fish & Shellfish Immunology, 2017
The mantle piece from the donor pearl oyster would be rejected by the immune system of recipient oyster in pearl culture practice, especially in the case that the donor and receptor are different species. Thus, investigation of the immune response of recipient oyster to grafted mantle pieces, particularly to xenografts, is of importance in creating ...

Cloning and characterization of an IKK homologue from pearl oyster, Pinctada fucata

Developmental & Comparative Immunology, 2008
IkappaB kinase (IKK) play central roles in cell signaling by regulating nuclear factor-kappaB (NF-kappaB) activation, which is involved in inflammatory response, proliferation, development and bone homeostasis. We report here for the first time that an IKK homologue was cloned and functionally characterized in pearl oyster, Pinctada fucata.

Expression and antimicrobial characterization of rhamnose-binding lectin in Pinctada fucata martensii

Fish & Shellfish Immunology
Rhamnose-binding lectins (RBLs) are key components of pattern recognition molecules involved in pathogen clearance during non-specific immune responses and play an important role in the immune response of Mollusca. Pinctada fucata martensii is an essential species for artificial seawater pearl cultivation in China.
