Increased eutrophication of water bodies promotes cyanobacterial blooming that is hazardous due to the production of various bioactive compounds. Microcystin-LR (MCLR) is among the most widespread cyanotoxins classified as possible human carcinogen, while cylindrospermopsin (CYN) has only recently been recognized as health concern. Both cyanotoxins are genotoxic; however, the mechanisms of their action...
Microcystins, which are hepatotoxins produced by cyanobacteria, have been reported to be potent tumour promoters, and there is an indication that they can also act as tumour initiators. They thus constitute a potential threat to human and animal health, at concentrations that do not cause acute hepatotoxic effects. The main target organ of microcystin toxicity is the liver; however, several studies...
Microcystins (MCs) are hepatotoxic cyclic heptapeptides produced by freshwater cyanobacteria. They are inhibitors of serine/threonine protein phosphatases 1A and 2A and are involved in liver tumour promotion. Several recent studies indicated that MCs are genotoxic and may also act as tumour initiators. Based on our previous results showing that microcystin-LR (MCLR) induces DNA damage in HepG2 cells,...
