Transcriptome Analysis to Study the Molecular Response in the Gill and Hepatopancreas Tissues of Macrobrachium nipponense to Salinity Acclimation

Frontiers in Physiology, Год журнала: 2022, Номер 13

Опубликована: Май 25, 2022

Macrobrachium nipponense is an economically important prawn species and common in Chinese inland capture fisheries. During aquaculture, M. can survive under freshwater low salinity conditions. The molecular mechanism underlying the response to acclimation remains unclear this species; thus, study, we used Illumina RNA sequencing platform for transcriptome analyses of gill hepatopancreas tissues exposed stress [0.4‰ (S0, control group), 6‰ (S6, 12‰ (S12, high group)]. Differentially expressed genes were identified, several adaptation-related terms signaling pathways found be enriched, such as “ion transport,” “oxidative phosphorylation,” “glycometabolism.” Quantitative real-time PCR demonstrated participation 12 key osmotic pressure regulation acute stress. Further, role carbonic anhydrase was investigated by subjecting situ hybridization. Collectively, results reported herein enhance our understanding mechanisms via which adapts changes salinity.

Influence of Anthropogenic Activities on Redox Regulation and Oxidative Stress Responses in Different Phyla of Animals in Coastal Water via Changing in Salinity

Water, Год журнала: 2022, Номер 14(24), С. 4026 - 4026

Опубликована: Дек. 9, 2022

Salinity is a decisive abiotic factor that modulates the physiology of aquatic organisms. itself modulated by various factors—most notably anthropogenic factors. In coastal regions, increasing salinity observed mostly due to elevated rate evaporation under high temperatures, especially global warming. addition, many other factors, climatic chemicals, etc., also contribute changes in water. Some these include rainfall, regional warming, precipitation, moisture, thermohaline circulation, gaseous pollutants, dissolved wind flow, and biocrusts. has been found regulate osmotic balance and, thus, can directly or indirectly influence biomarkers oxidative stress (OS) Imbalances OS potentially affect growth, production, reproduction organisms; therefore, they are being studied organisms economic aquacultural importance. Salinity-modulated redox regulation as function phylum covered this review. The literature from 1960 2021 indicates altered changing combination with (anthropogenic) factors species-specific, even within particular phylum. Thus, knowing response mechanisms such may be useful for management specific animals their habitats.

Energy Metabolism-Related Arginine Kinase Gene Expression in Mud Crab (Macrophthalmus japonicus) Following Irgarol Exposure

Applied Sciences, Год журнала: 2025, Номер 15(5), С. 2489 - 2489

Опубликована: Фев. 25, 2025

Antifouling paints are essentially used to prevent biological fouling of marine vessels and structures, but their release into the environment has resulted in various ecosystem problems. Irgarol, a representative antifouling paint substance, is well known for its direct effects on plankton productivity, studies harmful estuarine organisms limited. This study aimed determine impact irgarol exposure at transcriptional level Macrophthalmus japonicus, highly dominant crab species estuaries. To this end, we characterized M. japonicus arginine kinase (AK) gene, which plays role energy metabolism invertebrates, examined expression levels response exposure. Consequently, AK was identified as prevalent enzyme invertebrate species, including crustaceans insects. Following exposure, gills exhibited relatively elevated gene compared control group 4 7 days In addition, observed hepatopancreas. Notably, low concentrations 1 10 μg L−1 demonstrated comparatively higher hepatopancreas than high concentration 30 L−1. The results imply that may disrupt equilibrium metabolic processes regulated by crab. Moreover, sustained environmental accumulation indicates it serve significant disturbance factor within ecosystems.

Role of myo-inositol supplementation against toxicity of excessive dietary copper in Pacific white shrimp Litopenaeus vannamei

Ecotoxicology and Environmental Safety, Год журнала: 2022, Номер 241, С. 113712 - 113712

Опубликована: Июнь 2, 2022

Raw materials for making dried shrimp (a type of foodstuff) are mostly from farmed and preliminary findings indicated that head copper (Cu) concentrations in some commercial products exceeded the safe limit specified pollution-free aquatic (50 mg/kg), which may influence food safety. Therefore, a 63-day feeding trial was conducted to explore effects dietary Cu on accumulation tissues, growth performance, immune response antioxidant status Pacific white (Litopenaeus vannamei). Moderating effect myo-inositol (MI, adding 200 mg/kg diet) adverse impacts caused by excessive also investigated. 600 (initial weight: 0.89 ± 0.00 g) were divided into five groups: 37.08 mg Cu/kg diet group (control group), 62.57 group, 125.99 63.41 (supplemented with MI) 119.19 MI). The results showed increased over mg/kg, hepatopancreas raised 29.04 233.43–263.65 muscle only 6.22 6.99–8.39 mg/kg. Report control concentration (125.99 mg/kg) didn't significantly affect but it notably reduced whole body lipid content response, induced oxidative stress damaged structure, ameliorated MI supplementation. suggested consuming its processed weren't recommended. feeds should be controlled below Additionally, supplementation mitigated negative Cu.

Comparison of immune defense and antioxidant capacity between broodstock and hybrid offspring of juvenile shrimp (Macrobrachium nipponense): Response to acute ammonia stress

Animal Genetics, Год журнала: 2022, Номер 53(3), С. 380 - 392

Опубликована: Март 18, 2022

Ammonia is a major environmental pollutant in the aquatic system that poses great threat to health of shrimp. Macrobrachium nipponense, as one large-yield farmed shrimp, facing germplasm degradation. Genetic improvement through hybridization effective methods solve this problem. However, there are few studies on effects ammonia nitrogen resources M. nipponense. In study, broodstock populations (Dianshan, DS) and hybrid offspring (DS ♀ × CD [Changjiang, CJ ♂ Dongting, DT ♀], SCD) were exposed 0, 5, or 20 mg/L for 96 h. The survival rate SCD group was greater than DS group, although no significant differences weight gain length (p > 0.05). number positive cells apoptosis rates significantly after exposure < As concentration increased, antioxidant enzyme activities higher while hepatotoxicity lower trends expression antioxidant- immune-related genes generally consistent with enzymes. Our study found population had stronger stress resistance their parent at same concentration. This confirms our speculation has advantage immunity, which also provides reference follow-up chronic toxicity.
