The aim of this study was to evaluate the predictive value of the polymorphism Glutathione S-transferase P1 (GSTP1) Ile(105)Val on oxaliplatin/5-FU-based chemotherapy in advanced gastric cancer. Patients with advanced gastric cancer accepted oxaliplatin/5-FU-based chemotherapy as first-line chemotherapy were investigated. GSTP1 Ile(105)Val polymorphism was detected by TaqMan-MGB probe allelic d...

The amino acid sequence of Chromatium ferredoxin was determined by studies of thermolysin peptides of S-carboxymethylcysteinylferredoxin and chymotryptic peptides of oxidized ferredoxin. The 81 amino acid residues in the molecule have the following sequence: Ala-Leu-Met-IleThr-Asp-Gln-Cys-Ile-Asn-Cys-Asn-Val-Cys-Gln-ProGlu-Cys-Pro-Asn-Gly-Ala-Ile-Ser-Gln-Gly-Asp-Glu-ThrTyr-Val-Ile-Glu-Pro-Ser-L...

In the seed, a fundamental transition between embryo and vegetative phases of plant development is coordinated by the interaction between the AFL and VAL sub-clades of the plant specific B3 domain transcription factor family. The AFL B3 factors together with LEC1-type HAP3 transcription factors promote embryo maturation; whereas the VAL B3 factors repress the LEC1/AFL (LAFL) network during seed...

A common polymorphism of the brain-derived neurotrophic factor (BDNF) gene (Val66Met) has been implicated in anxiety, which is associated with lower vagal activity. We hypothesize that the BDNF Val66Met polymorphism may have a modulatory effect on the cardiac sympathovagal balance. A total of 211 healthy Chinese-Han adults (58 male, 153 female, aged 33.3 +/- 10.3 years) were recruited with thre...

PURPOSE Genetic polymorphisms may affect not only cancer development but also cancer progression, and as a result could influence cancer phenotypes. The aim of this study was to examine the relationship between breast cancer susceptibility gene polymorphisms and clinicopathological features. EXPERIMENTAL DESIGN We genotyped 664 Korean primary breast cancer patients for 17 single-nucleotide po...

BACKGROUND The genes encoding myeloperoxidase (MPO) and alpha(2)-macroglobulin (A2M) are involved in molecular pathways leading to beta-amyloid deposition. Two polymorphic sites in these genes (MPO-G/A and A2M-Ile/Val) have been associated with Alzheimer disease (AD), but conflicting findings have been reported in populations with different ethnic backgrounds. OBJECTIVES To study the associat...

It has been recently shown that Catechol O-methyltransferase (COMT) Val(158)Met polymorphism strongly influences prepulse inhibition (PPI) of the acoustic startle response (ASR) in healthy human volunteers. Given that schizophrenia patients exhibit impairment in PPI and that COMT is a putative susceptibility gene for schizophrenia, we investigated the impact of the COMT Val(158)Met polymorphism...

Although the isoleucyl-tRNA synthetase from Escherichia coli (IRS) does not catalyze the overall mischarging of tRNAIle with valine, it does undergo the first step of the reaction, the formation of an IRS-Val-AMP complex. The addition of tRNAIle to this complex leads to its quantitative hydrolysis and the IRS acts as an ATP pyrophosphate in the presence of valine and tRNAIle (Baldwin, A.N., and...
