The cancer cells follow three mechanisms to negate the effect of caspases: preventing the activation of the procaspases, neutralizing active caspases, and regulating the gene expression of either caspases or their activators.
These QSIs and the QS signal OdHL share a chemical backbone but the QSIs have antagonistic activity on the OdHL receptor preventing the activation of downstream virulence factors.
It has further been proposed, that NICD1 directly binds to and thereby suppresses the scaffold activity of JNK-interacting protein 1 (Jip1) thus preventing the activation of JNK.
Preventing the activation of NF-κB allows Sox9 to retain its full activity at the type II collagen enhancer in the presence of TNF-α [ 13], suggesting a relationship between these transcription factors.
Furthermore, simvastatin inhibited the migration and invasion of fibroblast-like synoviocytes by preventing the activation of RhoA, a small GTP-binding protein known to activate NF-κB, therefore identifying a novel therapeutic agent for RA [ 57].
This antibody destroys any Rh-positive fetal cells in the maternal circulation, thereby preventing the activation of the mother's immune system should she conceive another Rh-positive fetus.
c-FLIP functions to block FADD-mediated apoptosis by preventing the activation of the initiator pro-caspase 8, among several other roles.
Further mechanism studies revealed that 11a caused the G2 phase arrest of the cell cycle and induced apoptosis of U87 cells by preventing the activation of the PI3K/Akt pathway.
Thus, cFLIP exerts a critical role in tissue homeostasis by preventing the activation of monocytic cells and innate immunity, which causes cell death and inflammation in susceptible tissues.
In the story, she is instrumental in preventing the activation of the Halo installations, which would have destroyed all sentient life in the galaxy.
Mad2 is known to restrain the mitotic progression by preventing the activation of ubiquitin-dependent anaphase promoting proteolysis.
