Glutathione is important for metal tolerance since it may protect cells by: 1) metal chelation and sequestration; 2) protection against metal-induced oxidation since glutathione is considered the main redox buffer of the cell; and 3) binding to reactive sulphhydryl groups on proteins (glutathionylation) to shield them from irreversible metal binding and/or oxidative damage [ 25, 26].
For other diseases, we've developed advanced methods to fabricate antibodies that may protect cells from invasion.
Therefore, inhibition of QR2 by resveratrol may protect cells against reactive intermediates and eventually cancer.
They can catalyze redox reactions and may protect cells against oxidative stress.
The liposomal celecoxib treatment inhibits the tumor cell growth by antioxidant enzymes which directly resist the oxidant attack and may protect cells against lipid peroxidation and DNA damage.
In severe sepsis (SS) or trauma-related systemic inflammatory response syndrome (SIRS), induction of heat-shock-protein-72 (HSP72) may protect cells from stress.
Autophagy may protect cells against cell death under oxidative stress, due to higher likelihood that oxidized proteins will be taken up by autophagosomes and subsequently degraded by lysosomes.
The results indicate that the induced over-expression of OsDREB2A driven by the 4ABRC promoter in engineered rice plants may protect cells during stress.
These results suggest that temporary encapsulation of cells in gelatin microparticles may protect cells from short-term environmental effects such as those associated with the crosslinking of an injectable polymeric carrier for bone tissue engineering.
Some studies have shown that antioxidants may protect cells from the effects of free radicals, molecules produced by the body when it's exposed to ultraviolet rays, pollution and smoke.
However, under stress conditions, ROS accumulation affects cellular components, causing damage to membranes by lipid peroxidation (Smirnoff 1993), and/or by the accumulation of solutes, such as proline and betaine, which may protect cells against increased levels of ROS (Chen and Murata 2002).
