Some species of enterococci and streptococci are difficult to differentiate by phenotypic traits. The feasibility of using an oligonucleotide array for identification of 11 viridans group streptococci was previously established. The aim of this study was to expand the array to identify species of Abiotrophia (1 species), Enterococcus (18 species), Granulicatella (3 species), and Streptococcus (...
BACKGROUND Airborne fungi play an important role in causing allergy and infections in susceptible people. Identification of these fungi, based on morphological characteristics, is time-consuming, expertise-demanding, and could be inaccurate. METHODS We developed an oligonucleotide array that could accurately identify 21 important airborne fungi (13 genera) that may cause adverse health proble...
The objective of this study was mainly to develop and evaluate a membrane array-based method simultaneously detecting the expression levels of a multiple mRNA marker panel in the peripheral blood for used in complementary breast cancer diagnosis. The mRNA markers employed included cytokeratin 19 (CK-19), carcinoembryonic antigen (CEA), c-Met, Her2/neu, and mammaglobin (hMAM). The specimens of p...
This paper describes the development and validation of a PCR array for studying chemical-induced effects on gene expression of selected endocrine pathways along the hypothalamic-pituitary-gonadal (HPG) axis of the small, oviparous fish, the Japanese medaka (Oryzias latipes). The Japanese medaka HPG-PCR array combines the quantitative performance of SYBR Green-based real-time PCR with the multip...
Background: Disorders of sex development (DSDs) belong to uncommon pathologies and result from abnormalities during gonadal determination and differentiation. Various gene mutations involved in gonadal determination and differentiation have been associated with gonadal dysgenesis. Despite advances in exploration of genes and mechanisms involved in sex disorders, most children with severe 46,XY ...
Recently we evaluated a custom TaqMan array card (TAC) detection system, formerly known as a TaqMan low-density array (TLDA) card, for simultaneous real-time PCR identification of 21 pathogens and three control targets in duplicate from respiratory specimens (M. Kodani et al., J. Clin. Microbiol. 49:2175-2182, 2011). We engineered an adaptable and expandable system of in vitro RNA transcripts t...
Honey bees and other insects face many important parasites and pathogens against which they have evolved behavioral, morphological, physiological, and immune-based defenses. To help validate honey bee immune-gene candidates and determine their responsiveness to pathogens, a quantitative-PCR array was developed to measure transcript levels for 48 honey bee and pathogen genes in parallel. It is s...
Anaerobic bacteria can cause a wide variety of infections, and some of these infections can be serious. Conventional identification methods based on biochemical tests are often lengthy and can produce inconclusive results. An oligonucleotide array based on the 16S-23S rRNA intergenic spacer (ITS) sequences was developed to identify 28 species of anaerobic bacteria and Veillonella. The method co...
Hepatocellular carcinoma (HCC) has a high likelihood of recurrence and a poor prognosis. To detect cancer-related genes of HCC, we developed a new technique: triple combination array analysis, consisting of a methylation array, a gene expression array and a single nucleotide polymorphism array. A surgical specimen obtained from a 68-year-old female HCC patient was analyzed using triple combinat...
The array CGH technique (Array Comparative Genome Hybridization) has been developed to detect chromosomal copy number changes on a genome-wide and/or high-resolution scale. It is used in human genetics and oncology, with great promise for clinical application. Until recently primarily PCR amplified bacterial artificial chromosomes (BACs) or cDNAs have been spotted as elements on the array. The ...
