Evidence of the cost of the production of microcystins by Microcystis aeruginosa under differing light and nitrate environmental conditions. [PDF]

PLoS ONE, 2012
The cyanobacterium Microcystis aeruginosa is known to proliferate in freshwater ecosystems and to produce microcystins. It is now well established that much of the variability of bloom toxicity is due to differences in the relative proportions of ...

Effects of Dietary Astaxanthin Supplementation on Energy Budget and Bioaccumulation in Procambarus clarkii (Girard, 1852) Crayfish under Microcystin-LR Stress

Toxins, 2018
This research aimed to study the effects of astaxanthin on energy budget and bioaccumulation of microcystin-leucine-arginine (microcystin-LR) in the crayfish Procambarus clarkii (Girard, 1852).

Increased Prorenin Expression in the Kidneys May Be Involved in the Abnormal Renal Function Caused by Prolonged Environmental Exposure to Microcystin-LR

Toxics
Toxic algae in eutrophic lakes produce cyanotoxic microcystins. Prior research on the effect of microcystin-LR in the kidney utilized intraperitoneal injections, which did not reflect natural exposure.

Microcystin-LR incorporated into colonic cells through probenecid-sensitive transporters leads to upregulated MCP-1 expression induced by JNK activation

Toxicology Reports, 2022
Harmful algae that inhabit eutrophic lakes produce cyanotoxic microcystins. Therefore, the relationship between chronic exposure to microcystins via drinking water and organ disorders has been investigated.

Effects of different doses of microcystin-LR exposure on gut development and the microbiota of Xenopus laevis tadpoles

BMC Microbiology
Background Although the acute toxicity of microcystin-LR has been widely confirmed, its effects on aquatic organisms at environmental concentrations have not been systematically studied.

Selectivity and potency of microcystin congeners against OATP1B1 and OATP1B3 expressing cancer cells. [PDF]

PLoS ONE, 2014
Microcystins are potent phosphatase inhibitors and cellular toxins. They require active transport by OATP1B1 and OATP1B3 transporters for uptake into human cells, and the high expression of these transporters in the liver accounts for their selective ...

Biodegradation of [D-Leu1] microcystin-LR by a bacterium isolated from sediment of Patos Lagoon estuary, Brazil

Journal of Venomous Animals and Toxins including Tropical Diseases, 2015
Background Toxic cyanobacterial blooms are recurrent in Patos Lagoon, in southern Brazil. Among cyanotoxins, [D-Leu1] microcystin-LR is the predominant variant whose natural cycle involves water and sediment compartments. This study aimed to identify and

The Use of Sodium Hypochlorite at Point-of-Use to Remove Microcystins from Water Containers

Toxins, 2021
Most conventional water treatment plants are not sufficiently equipped to treat both intracellular and extracellular Microcystins in drinking water. However, the effectiveness of sodium hypochlorite in removing Microcystin in containers at the point-of ...

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.
