Immunostimulatory activity of the polysaccharides from Hyriopsis cumingii

International Journal of Biological Macromolecules, 2010
The immunostimulatory activity of Hyriopsis cumingii polysaccharides (HCPS) was evaluated by using in vitro cell models and in vivo animal models. The results demonstrated that crude HCPS and its purified fractions (HCPS-1, HCPS-2 and HCPS-3) could promote the splenocyte proliferation, increase the activity of acid phosphatase in peritoneal macrophages

Transcriptomic insights into the regulatory mechanisms of salinity stress response in Hyriopsis cumingii

open access: yes
Freshwater salinization has become an increasing threat to the culture of the freshwater pearl mussel Hyriopsis cumingii. To evaluate its physiological tolerance and regulatory responses to salinity stress, mussels were exposed to 0, 2, 4 and 6‰ salinity, and changes in survival, osmotic regulation, antioxidant capacity, energy metabolism, histology ...

Two NF-κB subunits are associated with antimicrobial immunity in Hyriopsis cumingii

Developmental & Comparative Immunology, 2022
The NF-κB pathway activated by bacteria and viruses produces a series of antimicrobial peptides that participate in the innate immune response. In this study, two NF-κB subunits were cloned and identified from Hyriopsis cumingii (named Hcp65 and Hcp105) using RT-PCR and RACE.

Effects of suppressing Smads expression on wound healing in Hyriopsis cumingii

Fish & Shellfish Immunology, 2020
As a specific pearl mussel in China, Hyriopsis cumingii has enormous economic value. However, the organism damage caused by pearl insertion is immeasurable. TGF-β/Smad signal transduction pathways are involved in all phases of wound healing. We have previously reported on two cytoplasmic signal transduction factors, Smad3 and Smad5 in mussel H ...

Preliminary characterization of proteoglycan from Hyriopsis cumingii.

Zhong yao cai = Zhongyaocai = Journal of Chinese medicinal materials, 2013
To study the preliminary characterizations of Hyriopsis cumingii proteoglycan (HCPG).The content of carbohydrate and protein were measured by spectrophotometry. FTIR spectrum was used to analyze the functional groups. Relative molecular mass and amino acid composition were detected by HPLC.

Expression of bone morphogenetic protein 10 and its role in biomineralization in Hyriopsis cumingii

International Journal of Biological Macromolecules, 2023
Shells and pearls are the products of biomineralization of shellfish after ingesting external mineral ions. Bone morphogenetic proteins (BMPs) play a role in a variety of biological function, and the genes that encode them, are considered important shell-forming genes in mollusks and are associated with shell and pearl formation, embryonic development,

miR-4504 is involved in nacre color formation in Hyriopsis cumingii

Biochemical and Biophysical Research Communications, 2019
Pearl color is affected by the nacre color of shells in Hyriopsis cumingii, and is the primary indicator of its value. MicroRNAs (miRNAs) are endogenous small non-coding RNAs that play important roles in many biological processes, including pigmentation.
