Special Issue Information

Dear Colleagues,

I would like to kindly invite you to contribute to this Special Issue, titled “Bioactive Compounds and Emerging Technologies for Aquatic Food”, which aims to cover the latest outstanding discoveries on bioactive compounds and related emerging technology of aquatic origin. Marine food is a rich source of health-promoting substances, such as bioactive peptides, polysaccharides, phenolic compounds, polyunsaturated lipids, minerals, and phytosterols. Additionally, extraction and processing technologies for bioactive compounds from aquatic food, such as gelatin, collagen, chitin, and chitosan, are different from those for general fruit and vegetables. This issue will focus on the potential health-promoting effects of these bioactive compounds and various emerging technologies for aquatic food. Research and review papers are both welcome.

The potential topics include, but are not limited to:

  • Extraction methodologies for the extraction of bioactive compounds from aquatic food;
  • The identification of functional compounds from aquatic food;
  • The evaluation of the beneficial effects of bioactive compounds in aquatic food;
  • The utilization of green technology in extracting and processing aquatic food.

The Anti-Muscle Atrophy Effects of Ishige sinicola in LPS-Induced C2C12 Myotubes through Its Antioxidant and Anti-Inflammatory Actions

Inflammation and oxidative stress are known to be major factors in muscle atrophy. The objective of this study was to evaluate whether the antioxidant activity of Ishige sinicola ethanol extract (ISE) and fractions from ISE could prevent lipopolysaccharide (LPS)-induced muscle atrophy in C2C12 myotubes. IS was extracted with ethanol and fractionated with five organic solvents. Then, ISE and five fractions from ISE were used to evaluate the total antioxidant activity and the protective effect of LPS-induced muscle atrophy in C2C12 myotubes. The ISE and butanol (BuOH) fraction showed higher total antioxidant activity and higher total phenol content than other fractions of ISE. The ISE and BuOH fraction significantly attenuated the LPS-induced diameter of C2C12 myotubes as well as the mRNA and protein expression levels of the muscle-specific E3 ubiquitin ligases. The mRNA expression of forkhead box O type 3α was stimulated by LPS, which was suppressed by the BuOH fraction but not ISE. Furthermore, ISE and the BuOH fraction significantly reduced LPS-stimulated gene expression of pro-inflammatory cytokines and inflammation-inducible enzymes, which was mediated by through the inhibition of the p38/extracellular signal-regulated kinase signaling pathway. Thus, ISE exerts a protective effect against muscle atrophy in LPS-induced C2C12 myotubes through the antioxidant activity and anti-inflammatory effects of ISE. Full article

The purpose of this study was to prepare a clinical trial test material (ESETM, test material of Ecklonia stolonifera extract) to develop a health functional food based on its anti-obesity effect. The anti-obesity effect of ESETM was evaluated in 3T3-L1 adipocytes and obese mice fed a high-fat diet (HFD) to confirm its nonclinical trial effect before application in clinical trial. Adipogenesis is a process of preadipocyte differentiation that causes an increase in the production of reactive oxygen species (ROS) and lipid accumulation. In vitro study results indicated that ESETM outstandingly inhibits the production of ROS and lipid accumulation during adipogenesis and lipogenesis. In vivo, ESETM-treated ICR mice had reduced HFD-induced weight change, food efficiency ratio, adipose tissue weight, liver weight and showed improved serum lipid profiles. Our results show that ESETM inhibits weight change by regulating the adipogenesis, lipogenesis, lipolysis, and thermogenesis pathways. Full article

Historically, various types of shellfish inhabited the Jeju area to the extent that large mounds of shells were found. However, the most endangered of such species, Mactra chinensis, currently inhabits only a few villages on Jeju Island. This pioneering study aimed to explore the effect of the environment on M. chinensis larval growth on Jeju Island. First, we assume that the findings of this study are based on the specific environmental situations and conditions of Jeju Island. This study mostly explored the effects of environment and food diversity (microalgal species) on the growth and survival of M. chinensis (hen clam) larvae. The average seawater temperature ranges between 19 and 22 °C during the summer season. We tested analogous seawater temperature conditions specific to the Jeju coastal environment: 17, 22, 27 and 32 °C. M. chinensis larvae reared at higher temperatures experienced higher growth but lower survival rates, reaching shell lengths of >220 μm at 15 days after hatching. The larvae exhibited the lowest growth (149.3 μm shell length) at 17 °C. Moreover, the M. chinensis larvae had the highest daily growth and survival rate of 10.3 μm and 75.5%, respectively, at a salinity of 30 practical salinity units (psu). For breeding Jeju hen clams, we found that the optimal water temperature and salinity for larval rearing were 22 °C and 30–35 psu, respectively. Larvae fed only I. galbana or Isochrysis sp. also exhibited high growth and survival rates. However, larvae restricted to a diet containing only P. lutheri exhibited low growth and survival rates. Therefore, the optimal diet of M. chinensis larvae should include more than one species of microalga, particularly I. galbana and Isochrysis sp., to increase their growth and survival rates, and hence the productivity of this clam species.
