Laser capture microdissection (LCM) allows microscopic procurement of specific cell types from tissue sections that can then be used for gene expression analysis. In conventional LCM, frozen tissues stained with hematoxylin are normally used to the molecular analysis. Recent studies suggested that it is possible to carry out gene expression analysis of formaldehyde-fixated paraffin embedded (FF...

BACKGROUND AND OBJECTIVE Survivin has gradually become an important target in diagnosis, prognosis prediction and treatment of tumor. There are many studies on urine-based survivin mRNA test using reverse transcription-polymerase chain reaction (RT-PCR) as a noninvasive examination for bladder cancer. However, its clinical value remains controversial. This study was to evaluate the diagnostic v...

In this article, the development of a new TaqMan-based one-step real-time reverse transcriptase-polymerase chain reaction (RT-PCR) assay for detection and quantification of Crimean-Congo hemorrhagic fever virus (CCHFV) RNA is described. Selected oligos targeting the highly conserved S region of CCHFV were designed by using our oligo design and analysis software, Oligoware 1.0. None of the prime...

To the Editor: AsCheung et al. (1) report, accurate assessment ofminimal disease is essential to inform the fight to cure children with neuroblastoma. Cheung et al. have exploited gene expression profiling to identify and prioritize targets for the detection of this disease using quantitative reverse transcriptase-PCR (RT-PCR). Eight of 34 genes are prioritized for investigation. Using a simila...

Quantitative PCR (Q-PCR or real-time PCR) approaches are now widely applied in microbial ecology to quantify the abundance and expression of taxonomic and functional gene markers within the environment. Q-PCR-based analyses combine 'traditional' end-point detection PCR with fluorescent detection technologies to record the accumulation of amplicons in 'real time' during each cycle of the PCR amp...

PURPOSE Hepatocellular carcinoma (HCC) patients with the same clinicopathologic features can have remarkably different disease outcomes after curative hepatectomy. To address this issue, we evaluated the cDNA microarray gene expression profiles of HCCs and identified claudin-10 expression level was associated with disease recurrence. The aim of the current study is to validate the microarray da...

Poorly executed and inadequately reported molecular measurement methods are amongst the causes underlying the lack of reproducibility of much biomedical research. Although several high impact factor journals have acknowledged their past failure to scrutinise adequately the technical soundness of manuscripts, there is a perplexing reluctance to implement basic corrective measures. The reverse tr...
