Ammonia nitrogen stress damages the intestinal mucosal barrier of yellow catfish (Pelteobagrus fulvidraco) and induces intestinal inflammation [PDF]

Frontiers in Physiology, 2023
Nitrogen from ammonia is one of the most common pollutants toxics to aquatic species in aquatic environment. The intestinal mucosa is one of the key mucosal defenses of aquatic species, and the accumulation of ammonia nitrogen in water environment will ...

Pva-miR-252 participates in ammonia nitrogen-induced oxidative stress by modulating autophagy in Penaeus vannamei

Ecotoxicology and Environmental Safety, 2021
MicroRNAs (miRNAs) are critical post-transcriptional regulators, which play a crucial role in resistance to adverse environmental stress by regulating autophagy. However, the mechanism of miRNA involved in the autophagy regulation of shrimp under ammonia

Evaluating the response of Schizothorax prenanti to ammonia nitrogen stress using computer vision and transcriptomics

Aquaculture Reports
The tolerance and response to ammonia nitrogen have not been studied in Schizothorax prenanti (S. prenanti), an important economic fish in southwest China. This study, for the first time, combines behavioral, histological, biochemical, and transcriptomic

Apoptotic Changes, Oxidative Stress and Immunomodulatory Effects in the Liver of Japanese Seabass (Lateolabrax japonicus) Induced by Ammonia-Nitrogen Stress during Keep-Live Transport. [PDF]

Biology (Basel), 2023
This study investigated the effects of NH3-N on antioxidant responses, histoarchitecture, and immunity of Japanese seabass (Lateolabrax japonicus) during keep-live transport. The findings suggest that NH3-N stress transport alters the transcription of P53, Caspase 9, Bcl2, Caspase 3 and Bax genes, demonstrating that NH3-N stress can trigger the ...

Toxic Effects on Bioaccumulation, Hematological Parameters, Oxidative Stress, Immune Responses and Tissue Structure in Fish Exposed to Ammonia Nitrogen: A Review

Animals, 2021
Ammonia nitrogen is the major oxygen-consuming pollutant in aquatic environments. Exposure to ammonia nitrogen in the aquatic environment can lead to bioaccumulation in fish, and the ammonia nitrogen concentration is the main determinant of accumulation.

Integrated Analysis of Transcriptome and Metabolome Reveals Molecular Responses to Ammonia Stress in the Gills of Litopenaeus vannamei Under Low-Salinity Conditions [PDF]

Biology
High ammonia nitrogen stress significantly compromises the survival of Litopenaeus vannamei under low-salinity conditions. However, existing studies predominantly focus on ammonia nitrogen responses under single stressors or normal seawater salinity. The
