Biological Activity

Description	Vitamin U (Methylmethioninesulfonium Chloride, Cabagin-U, Smethylmethionine) is a vitamin found in green vegetables. It is used in the treatment of peptic ulcers, colitis, and gastritis and has an effect on secretory, acid-forming, and enzymatic functions of the intestinal tract.
In vitro	Vitamin U inhibits adipocyte differentiation via down-regulation of adipogenic factors and up-regulation of AMPK activity^[1]. Vitamin U, also known as S-methyl methionine is found to increase activity of S-adenosyl-L-homocysteine. This decreases the inhibition of S-adenosyl-L-homocystein and stimulates methylation process^[2].
In vivo	"vitamin U" is recommended for treating oesophagogastric lesions, chronic gastric ulceration, chronic gastritis, ulcerative colitis, diaphragmatic hernias and peptic ulcers. "Vitamin U" is also recommended as a preventive vitamin for the digestive and intestinal systems. It is found that vitamin U can be used as a donor of methyl groups during bacterial DNA methylation in vivo without changing the specificity of DNA methylation. Vitamin U dose-dependently lowers the increased plasma LDL and normalizes the decreased HDL in dietary-induced hyperlipidemic rats^[2].

Protocol (from reference)

Cell Assay:^{^[1]}	Cell lines 3T3-L1 pre-adipocyte cell lines Concentrations 10, 50, 70, 90, 100 mM Incubation Time 24 h Method 3T3-L1 cells are treated with lipopolysaccharide (100 ng), interferon-γ (10 ng) and different concentrations of S-methylmethionine sulfonium chloride (50, 70, 90, 100 mM). After cells are incubated for 24 hr, MTT (5 mg/ml) is added. Then, the supernatant is discarded, dimethyl sulfoxide is added to the cells and formazan is formed via MTT reduction. Cell viability is measured using an ELISA at 570 nm.
