Mechanisms of microcystin-LR toxicity
Microcystin-LR (MCLR) is a cyanobacterial hepatotoxin that inhibits serine/threonine protein phosphatases types 1 and 2A in hepatocytes in vivo and in vitro, and disrupts actin microfilament (MF), microtubule (MT) and intermediate filament (IF) networks. The sequential ultrastructural and …

Toxicopathology of microcystin-LR in vivo and in vitro
Microcystin-LR (MCLR), produced by the blue-green alga Microcystis aeruginosa, causes death of livestock and is a public health hazard. The mechanism of MCLR toxicity was investigated using the rat. Changes in serum chemistry parameters and morphology caused by MCLR were characterized in vivo and …

The toxicity of microcystin-LR in swine and mice
Microcystin-LR (MCLR) is a monocyclic heptapeptide hepatotoxin produced by the cyanobacterium Microcystis aeruginosa. One gilt given whole M. aeruginosa cells ig containing 0.3% MCLR and des-methyl MCLR at 2.1 g/kg had severe panlobular hepatic necrosis and hemorrhage when euthanatized at 32.5 hr …

Crayfish as a biomonitor for the algal toxin microcystin-LR
… Microcystis produces the hepatotoxin microcystin-LR. Removing this toxin from drinking water requires expensive treatments; current analytical methods are incapable of real-time monitoring. Crayfish are resistant to microcystin-LR toxicity and respond well to operant conditioning. I hypothesized …

The destruction of the cyanobacterial toxin microcystin-LR by semiconductor photocatalysis.
… in these poisonings has been microcystin-LR, which has prompted the World Health Organisation (WHO) to set a guideline for the recommended safe level of this toxin in drinking water of 1 mgl-1. Removal of microcystin-LR from potable waters has proven to be inefficient using conventional …

Toxicity of microcystin-LR in hepatocytes and non-hepatocytes in vitro
Microystin-LR (MCLR), a cyanobacterial heptapeptide is an inhibitor of protein phosphatases 1 and 2A (PPs), a potential tumor promoter in rat liver, and selectively toxic to the liver in vivo and isolated hepatocytes in vitro. Inhibition of PPs has been linked to excessive phosphorylation and …

Pathways of Transport of Microcystin-LR from Microcystis aergonisa to the Benthic Environment
<p>Cyanobacterial harmful algal blooms (CHAB’s) are a global concern that affect humans and wildlife. <em>Microcystis aeruginosa </em>(<em>Microcystis)</em> is a freshwater photosynthetic cyanobacterium that is planktonic during warm months but has an overwintering benthic phase. <em>Microcystis …

Sublethal Hepatic Pathology and Evidence of Intranuclear Effects of the Cyanobacterial Toxin Microcystin -Lr
Microcystin-LR (MCLR) is a hepatotoxin and phosphatase inhibitor produced by Microcystis aeruginosa. The pathology of sublethal exposure is not well characterized. MCLR immunohistochemistry (MCLR-IHC) studies indicate that the nucleus may be a target of MCLR. Balb/c mice were given one sublethal …

An Approach to the Total Synthesis of the Protein Phosphatase 1 and 2A Inhibitor Microcystin -Lr
… synthetic route to the intermediate microcystin-LR-di-Boc-guanidine which can be converted to a constitutional isomer of microcystin-LR. Mass spectral analysis and HPLC retention time show the presence of microcystin-LR although a clean 1H NMR could not be obtained.
