Improved Real-Time RT-PCR Assays of Two Colorectal Cancer Peripheral Blood mRNA Biomarkers: A Pilot Study

Background: Efficient screening for detection of colorectal cancer (CRC) at earlier stages reduces its mortality. The purpose of this study was to investigate expression of carcinoembryonic antigen (CEA) and human telomerase reverse transcriptase (hTERT) mRNA in peripheral blood of CRC patients and to present strategies for early detection screen test. Methods: Twenty seven patients in non-meta...

Comparison of Enzyme Immunoassay, Immunochromatography, and RNA-Polyacrylamide-Gel Electrophoresis for Diagnosis of Rotavirus Infection in Children with Acute Gastroenteritis

Human rotavirus is a major etiologic agent for infantile diarrhea worldwide. It is responsible for up to 3.3 million deaths per year in children in developing countries. Various rapid and sensitive techniques have been developed to readily diagnose rotavirus gastroenteritis. In the present study, we compared the sensitivity and specificity of immunochromatography and RNA-polyacrylamide-gel elec...

The immunity conferred by anthrax avirulent uncapsulated live vaccine following different methods (intradermal and subcutaneous) of vaccination

The cloned RNA polymerase II transcription factor IID selects RNA polymerase III to transcribe the human U6 gene in vitro.

Although the human U2 and U6 snRNA genes are transcribed by different RNA polymerases (i.e., RNA polymerases II and III, respectively), their promoters are very similar in structure. Both contain a proximal sequence element (PSE) and an octamer motif-containing enhancer, and these elements are interchangeable between the two promoters. The RNA polymerase III specificity of the U6 promoter is co...

Different motif requirements for the localization zipcode element of β-actin mRNA binding by HuD and ZBP1

Interactions of RNA-binding proteins (RBPs) with their target transcripts are essential for regulating gene expression at the posttranscriptional level including mRNA export/localization, stability, and translation. ZBP1 and HuD are RBPs that play pivotal roles in mRNA transport and local translational control in neuronal processes. While HuD possesses three RNA recognition motifs (RRMs), ZBP1 ...
