PURPOSE During routine cell culture and under pathologic conditions, human retinal pigment epithelial (RPE) cells lose epithelial characteristics and change their morphology. In this study, changes in gene expression in RPE cells of different generations were evaluated by polymerase-chain-reaction-based differential display mRNA analysis (DD-RT-PCR). METHODS Total RNA was prepared from freshl...
OBJECTIVES To find potential diagnostic markers or therapeutic targets, we used differential display technique to identify genes that are over or under expressed in human ovarian cancer. METHODS Genes were initially identified by differential display between two human ovarian surface epithelium cultures and two ovarian cancer cell lines, A2780 and Caov-3. Genes were validated by relative quan...
Rapid and differential diagnosis of highly pathogenic avian influenza virus (HPAIV) subtype H5 is essential for the effective prevention and control of outbreaks caused by this pathogen. In this study, we describe a one-step multiplex real-time reverse transcription polymerase chain reaction (mRRT-PCR), using H5-, N1-, and N8-specific primers and probes, for differential detection of two HPAIVs...
Cataloging altered gene expression in young and senescent cells using enhanced differential display.
Recently, a novel PCR-based technique, differential display (DD), has facilitated the study of differentially expressed genes at the mRNA level. We report here an improved version of DD, which we call Enhanced Differential Display (EDD). We have modified the technique to enhance reproducibility and to facilitate sequencing and cloning. Using EDD, we have generated and verified a catalog of gene...
