Persistence of Microcystin in Three Agricultural Ponds in Georgia, USA

Toxins
Cyanobacteria and their toxins can have multiple effects on agricultural productivity and water bodies. Cyanotoxins can be transported to nearby crops and fields during irrigation and may pose a risk to animal health through water sources.

PHLPP is neither a Phosphatase nor a Tumor Suppressor

BioEssays, Volume 48, Issue 7, July 2026.
PH domain leucine‐rich repeat protein phosphatases (PHLPP) have been described as Akt phosphatases and tumor suppressors for more than 20 years. Recent evidence, however, indicates that they are pseudophosphatases that lost catalytic activity more than 450 Mya. This article argues that new hypotheses are urgently needed to reorient the field.

Shifting ice phenology and ice extent linked to harmful algal bloom severity

Limnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract Ice cover on lakes can have far‐reaching and profound effects on ecosystem structure and function. However, the duration and spatial extent of ice cover is changing rapidly with warming aquatic ecosystems. This loss of ice creates an urgent need to understand how lakes will function without ice cover, both during the ice‐on and ice‐free season,

Probable Microcystin Toxicosis in a Red-Gartered Coot (Fulica armillata) from a Protected Coastal Wetland in Central Chile—A Sentinel for Toxic Cyanobacterial Bloom?

Veterinary Sciences
Cyanobacterial harmful algal blooms are an increasing concern for wildlife health, particularly in eutrophic wetlands, yet well-documented avian cases supported by environmental, pathological, and toxicological evidence remain scarce.

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 ...

Historical Records of Nutrient Loading Into End‐Member Mid‐Latitude Lakes

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 7, July 2026.
Abstract Human‐induced environmental changes impact lakes in temperate regions, but detailed lake basin histories that pre‐date instrumental records are limited. Most paleolimnological reconstructions are used to examine single lakes in isolation, making it difficult to separate regional forcings from morphological influences on a sedimentary signal ...

Effects of Arsenate on Microcystin Content and Leakage of Microcystis Strain PCC7806 Under Various Phosphate Regimes [PDF]

, 2009
Both arsenic pollution and eutrophication are prominent environmental issues when considering the problem of global water pollution. It is important to reveal the effects of arsenic species on cyanobacterial growth and toxin yields to assess ecological ...

A Review of Cardiovascular Toxicity of Microcystins [PDF]

Toxins, 2019
The mortality rate of cardiovascular diseases (CVD) in China is on the rise. The increasing burden of CVD in China has become a major public health problem. Cyanobacterial blooms have been recently considered a global environmental concern. Microcystins (MCs) are the secondary products of cyanobacteria metabolism and the most harmful cyanotoxin found ...

Synthesis and use of the protein phosphatase affinity matrices microcystin-sepharose and microcystin-biotin-sepharose [PDF]

, 2007
Microcystin-based affinity matrices have been utilized to demonstrate the association of signaling proteins with protein phosphatases and for the purification of low-abundance microcystin-sensitive protein phosphatases.
