Microcystin pulldown of sperm PP2A.

, 2015
(A) Caudal sperm extracts (2X108 sperm/ml) were incubated with microcystin- sepharose beads. The microcystin- bound proteins were eluted by boiling with Laemmli buffer and analyzed by Western blot with Anti-PP2A antibody (MC).

Characterization of Taxonomic and Functional Dynamics Associated with Harmful Algal Bloom Formation in Recreational Water Ecosystems

Toxins
Harmful algal bloom (HAB) formation leads to the eutrophication of water ecosystems and may render recreational lakes unsuitable for human use. We evaluated the applicability and comparison of metabarcoding, metagenomics, qPCR, and ELISA-based methods ...

Growth and antioxidant system of the cyanobacterium Synechococcus elongatus in response to microcystin-RR

, 2005
Microcystins, one type of the cyanobacterial toxins, show a broad range of hazardous effects on other organisms. Most of the researches on the toxic effects of microcystins have involved in animals and higher plants.

Active and silent members in the mlr gene cluster of a microcystin-degrading bacterium isolated from Lake Taihu, China

, 2011
The microcystin-degrading genes, mlr, are important participants in the degradation process of hepatotoxic microcystins for several bacterial species. However, their expression status during degrading microcystins is still unknown. In order to study this

Variability of the microcystin synthetase gene cluster [PDF]

, 2005
In populations of Planktothrix, microcystin-producers and non-producers, which are morphologically identical, coexist. In order to develop a basis for the reliable detection of microcystin producers in field samples with polymerase chain reaction (PCR ...

The toxic effects of microcystin-LR on embryo-larval and juvenile development of loach, Misguruns mizolepis Gunthe

, 2002
Microcystin-LR, a specific and potent hepatotoxin, was tested for its effects oil loach embryo-larval and juvenile development, The results of this study showed that loach embryos were more sensitive when exposed to microcystin-LR at a later than at an ...

Pulsed galvanostatic control of a solid-contact ion-selective electrode for potentiometric biosensing of microcystin-LR

, 2016
We report here on the development of a chronopotentiometric assay for microcystin-LR based on enzymatic inhibition. The inhibition of protein phosphatase by microcystin-LR can be sensed potentiometrically by using 4-nitrophenyl phosphate as an enzyme ...

Microcystins and diseases

生物医学转化
Microcystins (MCs) are cyclic heptapeptide toxins produced by cyanobacteria and other algae; they pose severe threats to ecosystems and human health due to increasing global eutrophication. MCs can enter the human body through drinking water, the food chain, dermal contact, and aerosol inhalation.

Responses of antioxidant systems in the hepatocytes of common carp (Cyprinus carpio L.) to the toxicity of microcystin-LR

, 2003
The freshwater, bloom-forming cyanobacterium (blue-green alga) Microcystis aeruginosa produces a peptide hepatotoxin, which causes the damage of animal liver.
