Transcriptional alteration of cytoskeletal genes induced by microcystins in three organs of rats [PDF]

, 2010
This study explored the mechanisms of toxicity of microcystins by measuring the transcription levels of nine cytoskeletal genes (actin, tubulin, vimentin, ezrin, radixin, moesin, MAP1b, tau, stathmin) in the liver, kidney and spleen of male Wistar rats ...

Variations in the Microcystin Content of Different Fish Species Collected from a Eutrophic Lake

Toxins, 2013
Microcystins produced from cyanobacteria can accumulate in fish tissues. Liquid chromatography coupled with tandem quadrupole mass spectrometry (LC-MS/MS) is an attractive alternative to immunoassays for the determination of low concentrations of ...

Side‐dressing liquid manure into standing corn increases grain yield while maintaining post‐harvest soil nutrient status

Agronomy Journal, Volume 118, Issue 6, November/December 2026.
Abstract In the US Midwest, liquid manure is most commonly applied on bare soil after fall crop harvest, increasing the risk of nutrient loss during winter and early spring. Applying manure as a side‐dress into standing corn (Zea mays L.) using tankers or soft drag hose systems can better match seasonal plant N uptake, but producers need evidence that ...

Satellite Remote Sensing of Drinking Water Intakes in Lake Erie for Cyanobacteria Population Using Two MODIS-Based Indicators as a Potential Tool for Toxin Tracking

Frontiers in Marine Science, 2017
The growth of toxic Cyanobacterium, Microcystis aeruginosa, and the production of toxins, microcystins, pose serious concerns for the ecological health of lakes, such as western Lake Erie.

Synergistic and Antagonistic Effects of Chemical Pollutants and Parasitic Fungi on Cyanobacterial Metabolism

Environmental Toxicology, Volume 41, Issue 11, Page 1299-1310, November 2026.
ABSTRACT Freshwater ecosystems are increasingly impacted by anthropogenic pollutants, including the widely used herbicide metolachlor (MET) and cigarette butt (CB) litter. Parasites represent an additional biotic stressor that can modulate pollutant effects on their hosts.

Conventional and Emerging Protein Ingredients in Farinaceous Products: Amino Acid Quality, Digestibility, Biological Value, and Functional Performance

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 6, November 2026.
ABSTRACT The increasing demand for protein‐enriched foods has renewed interest in farinaceous products as widely consumed and technologically adaptable matrices for nutritional improvement. However, protein enrichment cannot be evaluated solely by increases in crude protein content, as nutritional value depends on essential amino acid (EAA) balance ...

Phytotoxicity associated to microcystins: a review [PDF]

Brazilian Journal of Biology, 2014
Microcystins (MC) are the most studied toxins of cyanobacteria since they are widely distributed and account for several cases of human and animal poisoning, being potent inhibitors of the serine/threonine protein phosphatases 1 (PP1) and 2A (PP2A). The phosphatases PP1 and PP2A are also present in plants, which may also suffer adverse effects due to ...

Isolation, Taxonomic Assignment, and Multi‐Assay Bioactivity Profiling of Sodaleptolyngbya sp. HX‐01 From Paddy Soil in Hoa Xuan

Chemistry &Biodiversity, Volume 23, Issue 10, October 2026.
The image shows cultivation and microscopic analysis of the cyanobacteria for its identification, subsequent to biomass harvesting and processing. The resultant extracellular metabolites are then concentrated for gas chromatography–mass spectrometry analysis profiling.
