Growing evidence suggests microRNAs (miRNAs) have an important role in tumorigenesis. MicroRNA-21 (miR-21) is up-regulated in many malignant tumors, including breast cancer. Its association with clinicopathologic features and expression of PTEN (phosphatase and tensin homolog deleted on chromosome 10), one of its target genes, in breast cancer has not been reported systematically. To further de...
The objective of this study was to develop a rapid, reproducible, and robust method for detecting Salmonella enterica serotype Enteritidis in poultry samples. First, for the extraction and purification of DNA from the preenrichment culture, four methods (boiling, alkaline lysis, Nucleospin, and Dynabeads DNA Direct System I) were compared. The most effective method was then combined with a real...
Real-time reverse transcription polymerase chain reaction (RT-PCR) methods that monitor product accumulation were adapted for the validation of differentially expressed genes. We describe a real-time quantitative PCR assay that uses SYBR Green I dye-based detection and product melting curve analysis to validate differentially expressed genes identified by gene expression profiling technologies....
This work presents a method to visualize the degradation of exogenous DNA in living cells using a novel type of activatable fluorescence imaging probe. Deoxyribonuclease (DNase)-activatable fluorescence probes (DFProbes) are composed of double strands deoxyribonucleic acid (dsDNA) which is labeled with fluorophore (ROX or Cy3) and quencher on the end of one of its strands, and stained with SYBR...
