Potential biomarkers for Crohn's disease (CD) and ulcerative colitis (UC) were identified from two sets of full thickness pathologic samples utilizing DermArray and PharmArray DNA microarrays relative to uninvolved (Un) colon or normal colon. Seven of the over-expressed genes were verified using quantitative RT-PCR (i.e., TMPT, FABP1, IFI27, LCN2, COL11A2,(More)
In this article, some of the advantages and limitations of DNA microarray technologies for gene expression profiling are summarized. As a model experiment, DermArray DNA microarrays were utilized to identify potential biomarkers of cultured normal human melanocytes in two different experimental comparisons. In the first case, melanocyte RNA was compared(More)
Biomarker genes of human skin-derived cells were identified by new simple bioinformatic methods and DNA microarray analysis utilizing in vitro cultures of normal neonatal human epidermal keratinocytes, melanocytes, and dermal fibroblasts. A survey of 4405 human cDNAs was performed using DermArray DNA microarrays. Biomarkers were rank ordered by "likelihood(More)
A very general procedure entitled complete relaxation and conformational exchange matrix (CORCEMA) analysis has been developed to analyze the 2D-NOESY spectra of interacting systems undergoing multistate conformational exchange. This is an extension of earlier work from this laboratory on the methodological treatment of multistate conformational exchange(More)
We report the results on the expression in Escherichia coli of a functional neurotoxin LqqV from the scorpion Leiurus quinquestriatus quinquestriatus. The gene for LqqV was synthesized using recursive PCR and expressed as a poly-histidine-tagged fusion protein in thioredoxin mutant E. coli strain [AD494(DE3)pLysS], thus permitting disulfide-bond formation.(More)
The solution structure of trypsin modulating oostatic factor (TMOF), a decapeptide (H-YDPAPPPPPP-OH) hormone that signals the termination of trypsin-like biosynthesis in mosquito midgut epithelial cells, was determined by 2-D 1H nuclear magnetic resonance spectroscopy and molecular modeling. The peptide forms a rod-shaped left-handed helix about 30 A long.(More)
This study established the utility of cross-species application of the cDNA microarray technique for investigating differential gene expression. Using both total RNA and mRNA samples recovered from two opossum cell lines derived from UVB-induced melanoma, we analyzed expression of ca. 4400 genes on the human DermArray DNA microarrays. The signals generated(More)
Ovine interferon tau (IFN tau) is a type I interferon that was originally identified as ovine trophoblast protein and is associated with the maternal recognition of pregnancy in sheep. Additionally, IFN tau possesses potent antiviral and antiproliferative activity without the corresponding toxicity found in known IFN alpha s. Structure-function studies with(More)
OGL-20P(T)-358 is a novel 66 amino acid residue protein from the hyperthermophile Thermococcus thioreducens sp. nov., strain OGL-20PT, which was collected from the wall of the hydrothermal black smoker in the Rainbow Vent along the mid-Atlantic ridge. This protein, which has no detectable sequence homology with proteins or domains of known function, has a(More)
From the original observation that the codons for the hydrophobic and hydrophilic amino acids on one strand of the DNA may be complemented by the codons for the hydrophilic and hydrophobic amino acids, respectively, on the complementary strand, arose the molecular recognition theory which forms the basis for much of the work involving complementary(More)
