Effect of RecA inactivation and detoxification systems on the evolution of ciprofloxacin resistance in Escherichia coli
(Oxford University Press, 2022)
Background Suppression of SOS response and overproduction of reactive oxygen species (ROS) through detoxification system suppression enhance the activity of fluoroquinolones. Objectives To evaluate the role of both ...

Glycogen Synthase Kinase-3-ß (GSK3ß) negatively regulates PTTG1/human Securin protein stability, and GSK3ß inactivation correlates with securin accumulation in breast tumors.
(The American Society for Biochemistry and Molecular Biology, 2011)
PTTG1, also known as securin, is an inactivating partner of separase, the major effector for chromosome segregation during mitosis. At the metaphase-to-anaphase transition, securin is targeted for proteasomal destruction ...
