Biochem/physiol Actions

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

Liver progenitor (oval) cells have enormous potential in the treatment of patients with liver disease using a cell therapy approach, but their use is limited by their scarcity and the number of donor livers from which they can be derived.

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.

DNA Damage and Repair

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.

Carcinogenesis and Epigenetics

Cancer research has revealed that the classical model of carcinogenesis, a three step process consisting of initiation, promotion, and progression, is not complete.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
