Regulation of Microcystin-LR-Induced DNA Damage by miR-451a in HL7702 Cells
Toxins, 2019 Microcystin-LR is a cyclic heptapeptide hepatotoxin produced by harmful cyanobacteria. A panel of microRNAs containing miR-451a were found to be significantly changed in normal human liver cells HL7702 after exposure to microcystin-LR (MC-LR) in our ...

VIEW, EarlyView.Electrochemical aptasensors are emerging as powerful platforms for precision diagnostics and environmental monitoring, owing to their high selectivity, programmability and compatibility with miniaturised systems. However, their broader application is constrained by limited signal intensity and challenges in reliable multiplexed detection.

Environmental Toxicology, Volume 41, Issue 10, Page 807-821, October 2026.ABSTRACT Cyanobacterial harmful algal blooms (cyanoHABs) threaten human, animal, and ecosystem health and safety through production of toxic secondary metabolites. Microcystis, a cosmopolitan bloom‐forming cyanobacterial genus, is well‐known for producing hepatotoxic microcystins (MCs), but it can produce many other bioactive cyanopeptides, such as ...

Dog Poisonings Associated with a Microcystis aeruginosa Bloom in the Netherlands
Toxins, 2013 In early autumn 2011, three dogs died after they had been exposed to a Microcystis aeruginosa bloom on Lake Amstelmeer, The Netherlands. The cyanobacterial scum from the lake contained up to 5.27 × 103 μg g−1 dry-weight microcystin, the vomit of one of ...

Microcystin-LR in surface water of Ponjavica river
Vojnosanitetski pregled, 2012 Background/Aim. Cyanobacterial toxins befall a group of various compounds according to chemical structure and health effects on people and animals. The most significant in this large group of compounds are microcystins. Their presence in water used for human consumption causes serious health problems, liver beeing the target organ ...

How Epitranscriptomic Machinery Senses Environmental Cues
Advanced Biology, Volume 10, Issue 9, September 2026.Exogenous exposures, microenvironmental signals, and intracellular metabolic or redox states can alter RNA‐modification machinery through catalytic chemistry, signaling‐dependent PTMs, compartmental redistribution, or changes in abundance and composition.

Early physiological and biochemical responses of rice seedlings to low concentration of microcystin-LR [PDF]
, 2013 Microcystin-leucine and arginine (microcystin- LR) is a cyanotoxin produced by cyanobacteria like Microcystis aeruginosa, and it’s considered a threat to water quality, agriculture, and human health.

Biological Reviews, Volume 101, Issue 4, Page 1904-1921, August 2026.ABSTRACT One of the major subfields of chemical ecology is the study of toxins and how they mediate interactions between organisms. Toxins produced by harmful algae (phycotoxins) impact a wide variety of organisms connected to the marine food web. Significant research efforts have thus aimed to identify the ecological and evolutionary drivers behind ...
