The mechanisms linking obesity and inactivity to diabetes mellitus are unclear. Recent studies have shown associations of alanine aminotransferase (ALT) and gamma-glutamyltransferase (GGT) with diabetes. In a random sample of 3,789 British women aged 60-79 years, the authors examined the associations of obesity and physical activity with ALT and GGT (1999-2001). Both body mass index and waist:h...

BACKGROUND Recently, it has been reported that gamma-glumyltransferase (GGT) is associated with various cardiovascular risk factors including overweight in adults. However, there are few studies on the relationship between GGT and cardiovascular risk factors in children. The aim of this study was to assess the relationship between serum GGT level and overweight in Korean urban children. METHO...

Gamma glutamyl transpeptidase (GGT) is a transferase, which is of great importance in sustaining intracellular cysteine and glutathione levels. The abnormal expression of GGT is significantly associated with features of many metabolic syndromes (e.g., hepatocellular carcinoma). Therefore, it is essential to develop methods to detect GGT so as to monitor the physiological or pathological phenome...

Gamma-glutamyltransferase (GGT), regarded as a marker of excessive alcohol consumption or liver disturbances, is an enzyme catalyzing the first step in the extracellular degradation of the antioxidant glutathione (GSH) and may take part in atherogenesis. The marked relationship between GGT and the atherosclerotic process has shifted attention to the issue of whether its serum levels can aid in ...

Pei Chen1, Xiucong Sun2, and Chao Han3 Beihang University, Beijing, 100191, People’s Republic of China Nomenclature U = gravitational potential, m2/s2 T = gravity gradient tensor (GGT), E TECEF = GGT in ECEF, E TENU = GGT in ENU, E TEIG = GGT in the Eigen frame, E T0 = GGT in GRF, E LA→B = rotation matrix from A to B r = observation position, m x, y, z = cartesian coordinates of r r, φ, λ = sph...

The relation of coffee drinking and other behavioral factors to serum gamma-glutamyltransferase (GGT) was examined in 2,494 male self-defense officials aged 48-56 years, who received a retirement health examination at the Self-Defense Forces Fukuoka Hospital between October 1986 and December 1990. Coffee, but not green tea, consumption was inversely related to serum GGT independently of body ma...

Agrin activates the transmembrane tyrosine kinase MuSK to mediate acetylcholine receptor (AChR) clustering at the neuromuscular junction (NMJ). However, the intracellular signaling mechanism downstream of MuSK is poorly characterized. This study provides evidence that geranylgeranyltransferase I (GGT) is an important signaling component in the Agrin/MuSK pathway. Agrin causes a rapid increase i...

BACKGROUND Gamma-glutamyl transpeptidase (GGT) which plays an important role in tumor initiation, invasion, drug resistance is strongly associated with poor prognosis in patients with cancers. This study was designed to estimate whether pretreatment serum GGT could predict the clinical outcome of nasopharyngeal carcinoma (NPC) patients. RESULTS An optimal cutoff value was identified as 23 U/L...

When grown in glucose or fructose medium in the absence of sucrose, Leuconostoc mesenteroides NRRL B-1299 produces two distinct extracellular dextransucrases named glucose glucosyltransferase (GGT) and fructose glucosyltransferase (FGT). The production level of GGT and FGT is 10 to 20 times lower than that of the extracellular dextransucrase sucrose glucosyltransferase (SGT) produced on sucrose...

Obesity is psychological and socioeconomic problems as well as health problems related to physical disease and disorder. The obesity epidemic, including a marked increase in the prevalence of obesity among pregnant women, represents a critical public health problem throughout the world. Gung-Gui-Tang (GGT), a prescription of traditional Korean medicine, has been used to treat dizziness due to l...
