An analog of methionine that interferes with the normal methylation of DNA and other methylation pathways, and induces pancreatic toxicity and liver cancer. However, in animal studies, it has also been shown to act synergistically with methionine-depletion to block the growth and metastasis of methionine-dependent tumors.
Methionine gamma-lyase (MGL) catalyzes the degradation of L-methionine to alpha-ketobutyrate, methanethiol and ammonia. The Arabidopsis (Arabidopsis thaliana) genome includes a single gene (At1g64660) encoding a protein (AtMGL) with approximately 35% identity to bacterial and protozoan MGLs. When overexpressed in Escherichia

Activation of myofibroblasts (MF) and extracellular matrix (ECM) deposition predispose the expansion and differentiation of liver progenitor cells (LPC) during chronic liver injury. Because Kupffer cells (KC) are active modulators of tissue response and fibrosis, we analyzed their role in

In (1)H NMR metabolomic datasets, there are often over a thousand peaks per spectrum, many of which change position drastically between samples. Automatic alignment, annotation, and quantification of all the metabolites of interest in such datasets have not been feasible.

The roles of methionine metabolism in bovine preimplantation embryo development were investigated by using ethionine, an antimetabolite of methionine. In vitro produced bovine embryos that had developed to the 5-cell stage or more at 72 h after the commencement of
In advanced liver damage, hepatic regeneration can occur through proliferation of a resident hepatic progenitor cell (HPC) population. HPCs are located within a designated niche in close association with myofibroblasts and bone marrow (BM) derived macrophages. Extra-cellular matrix (ECM) laminin
DNA damage and repair mechanism is vital for maintaining DNA integrity. Damage to cellular DNA is involved in mutagenesis, the development of cancer among others.
Cancer research has revealed that the classical model of carcinogenesis, a three step process consisting of initiation, promotion, and progression, is not complete.
