Background Decoy receptor 3 (DcR3), a member of the tumor necrosis factor receptor (TNFR) superfamily, shows inhibitory effects on Fas-mediated apoptosis. Currently, data are lacking on the correlation between DcR3 and the recurrence of breast cancer. The authors examined DcR3 mRNA expression and genomic amplification in breast cancer, and investigated the effect of DcR3 gene amplification on p...

We investigated c-Met overexpression and MET gene amplification in gliomas to determine their incidence and prognostic significance. c-Met immunohistochemistry and MET gene fluorescence in situ hybridization were carried out on tissue microarrays from 250 patients with gliomas (137 grade IV GBMs and 113 grade II and III diffuse gliomas). Clinicopathological features of these cases were reviewed...

Molecular beacons represent a new family of fluorescent probes for nucleic acids, and have found broad applications in recent years due to their unique advantages over traditional probes. Detection of nucleic acids using molecular beacons has been based on hybridization between target molecules and molecular beacons in a 1:1 stoichiometric ratio. The stoichiometric hybridization, however, puts ...

Both mutation and amplification of epidermal growth factor receptor (EGFR) in lung cancers have been reported in association with clinical responses to tyrosine kinase inhibitors. We have reported evidence implicating mutation specifically in the "terminal respiratory unit" type of adenocarcinoma, which is characterized by expression of thyroid transcription factor 1, a lineage marker of periph...

We delineated the mechanism regulating the inhibition of centrosome amplification by metformin in Drosophila intestinal stem cells (ISCs). Age-related changes in tissue-resident stem cells may be closely associated with tissue aging and age-related diseases, such as cancer. Centrosome amplification is a hallmark of cancers. Our recent work showed that Drosophila ISCs are an excellent model for ...

This paper extends existing research on the dynamic behaviour of supply chains by including influence online reviews. We model an chain which contains customers and one e-commerce retailer. By using simulation, we compare performance in a for two scenarios, namely adopting review systems without systems. The is measured bullwhip effect inventory variance amplification. results demonstrate that ...

optimization of the condition for pcr-directed sequencing of microsatellites poly adenine (a) length polymorphisms is more difficult and sensitive compared with other common sequences. replication slippage may occur for polymerase enzyme during microsatellite amplification and direct sequencing of these pcr products will be challenging for heterozygote samples. so, the aim of this study is to i...
