Señalización pro-apoptótica mediada por microcistina-LR en ratones intoxicados subcrónicamente
, 2010 La microcistina-LR (MC-LR) es una toxina producida por cianobacterias de agua fresca capaz de generar graves intoxicaciones tanto en animales como en humanos. Se sugiere que la acción de MC-LR se debe a un aumento del estrés oxidativo y a su capacidad de inhibir proteínas fosfatasas tipo 1 y 2A (PP1 y PP2A), lo cual deriva en hiperfosforilación ...

Variation in the synthesis of microcystin in response to saline and osmotic stress in Microcystis ruginosa PCC7806 [PDF]
, 2015 The growth and synthesis of microcystin in Microcystis aeruginosa PCC7806 was studied in cells grown in the presence of NaCl or with sucrose. The saline stress caused a decrease in the transcript levels of mcyD, one of the genes involved in microcystin ...

, 2006 A determinate condizioni ambientali (pH e temperature elevate), Microcystis può dar luogo a fioriture tossiche. La tossina prodotta, la microcistina, è un eptapeptide a basso peso molecolare, presente comunemente nella forma LR. Rilievi condotti a Massaciuccoli dall'Arpat (Simoni et al., 2004) hanno mostrato l'accumulo di microcistina nei tessuti di ...
