Metabolomic profiles delineate potential role for sarcosine in prostate cancer progression.
Nature 457(7231) , 910-4, (2009) Multiple, complex molecular events characterize cancer development and progression. Deciphering the molecular networks that distinguish organ-confined disease from metastatic disease may lead to the identification of critical biomarkers for cancer invasion an... |

Molecular pathway of near-infrared laser phototoxicity involves ATF-4 orchestrated ER stress.
Sci. Rep. 5 , 10581, (2015) High power lasers are used extensively in medicine while lower power applications are popular for optical imaging, optogenetics, skin rejuvenation and a therapeutic modality termed photobiomodulation (PBM). This study addresses the therapeutic dose limits, bi... |

A pitfall associated with lactate detection using stimulated-echo proton spectroscopy.
Magn. Reson. Med. 17(2) , 533-8, (1991) At TE values of 136 ms, it has recently been shown that the lactate methyl signal, when obtained with a stimulated-echo (STE) sequence, is modulated at the zero-quantum (ZQ) frequency when TM is varied. Here we describe an additional modulation of the ZQ lact... |

Importance of product inhibition in the kinetics of the acylase hydrolysis reaction by differential stopped flow microcalorimetry.
Anal. Biochem. 308 , 285-293, (2002) The hydrolysis of N-acetyl-L-methionine, N-acetylglycine, N-acetyl-L-phenylalanine, and N-acetyl-L-alanine at 298.35K by porcine kidney acylase I (EC 3.5.1.14) was monitored by the heat released upon mixing of the substrate and enzyme in a differential stoppe... |

Purification, characterization, molecular cloning, and expression of a new aminoacylase from Streptomyces mobaraensis that can hydrolyze N-(middle/long)-chain-fatty-acyl-L-amino acids as well as N-short-chain-acyl-L-amino acids.
Biosci. Biotechnol. Biochem. 73(9) , 1940-1947, (2009) We report here on the purification, characterization, molecular cloning, and expression of a new aminoacylase, initially isolated from the supernatant of Streptomyces mobaraensis (Sm-AA). Purified wild-type Sm-AA was found to be a monomeric protein with a mol... |

Selenium and selenomethionine levels in prostate cancer patients.
Cancer Detect. Prev. 28(1) , 8-16, (2004) Selenium (Se) and selenomethionine (Se-Met) have been identified as potential chemopreventive agents of prostate cancer. Using an assay for the speciation (separation and identification) and quantification of selenoamino acids, Se-Met was profiled in serum an... |

Urinary unconjugated 5 alpha-androstane-3 alpha, 17 beta-diol in patients with prostatic tumours.
Urol. Res. 10(2) , 81-4, (1982) A sensitive and reliable radioimmunoassay (RIA) for urinary unconjugated 5 alpha-androstane-3 alpha, 17 beta-diol is described. The mean overall recovery of unconjugated 5 alpha-androstane-3 alpha, 17 beta-diol was found to be 57.4%. The sensitivity of the as... |

Plasma carotenoids, retinol, and tocopherols and the risk of prostate cancer in the European Prospective Investigation into Cancer and Nutrition study.
Am. J. Clin. Nutr. 86(3) , 672-81, (2007) Previous studies suggest that high plasma concentrations of carotenoids, retinol, or tocopherols may reduce the risk of prostate cancer.We aimed to examine the associations between plasma concentrations of 7 carotenoids, retinol, alpha-tocopherol, and gamma-t... |

Glucose 6-phosphate dehydrogenase from human erythrocytes: identification of N-acetyl-alanine at the N-terminus of the mature protein.
Biochem. Biophys. Res. Commun. 207(1) , 331-8, (1995) Glucose 6-phosphate dehydrogenase from human erythrocytes has a blocked amino-terminus and no information could be obtained by direct sequencing of the intact protein. The peptide corresponding to the amino-terminal region was isolated from a tryptic digest o... |

Substrate specificity of an acylaminopeptidase that catalyzes the cleavage of the blocked amino termini of peptides.
Biochim. Biophys. Acta 953(3) , 357-60, (1988) An acylaminopeptidase purified from human red cells cleaves acetylated dipeptides in the decreasing order of acetyl-Ala, acetyl-Met, acetyl-Ser, acetyl-Gly and acetyl-Val. In addition, it was also found that the nature of the second amino-acid residue influen... |
