Tumors have been likened to "wounds that never heal" [ 64], which is reflected by shared expression of genes mediating breakdown of the extracellular matrix, productive chronic inflammation, and angiogenesis.
From preliminary investigations, one of us had seen that CYP2C9 and several other liver microsomal CYPs could not mediate the breakdown of peroxide on its own, to any noticeable extent.
Autophagy collectively refers to a group of intracellular degradation pathways that mediate the breakdown of intracellular material in lysosomes.
DOM may be affected by host-derived enzymes, such as MMPs, which mediate the breakdown of practically all extracellular matrix molecules, including native and denatured collagen [ 11, 12].
However, because activated calpains mediate proteolytic breakdown of PARP-1, the temporal association of PARP-1 and calpain in AIF nuclear translocation may be phase-dependent, more studies will be required to address this.
According to the current understanding of cachexia, various inflammatory cytokines lead to the up-regulation of enzymes called E3 ubiquitin ligases, which then mediate the breakdown of the proteins that make up sarcomeres, which are the basic building blocks of muscle.
The protein mediates the breakdown of extra-cellular matrix a process needed for basement-membrane penetration during metastasis and its over-expression has been associated with many different tumours.
SOD catalyzes the dismutation of the superoxide anion, and GPx mediates the breakdown of hydrogen peroxide.
DNASE1L3 encodes a member of the DNase family and functions as an endonuclease capable of cleaving DNA, mediating the breakdown of DNA during apoptosis.
This cytosolic protein can maintain glutamate and GSH homeostasis during stress by mediating the breakdown of xenobiotics conjugated to GSH [ 31].
