Integrin β6 expression in colorectal cancer cells promotes liver metastasis through enhanced adhesion to endothelial fibronectin

open access: yesInternational Journal of Cancer, EarlyView.
What's New? Integrins are critical mediators of cell adhesion and migration and have been implicated in cancer progression. Here, the authors show that endothelial cells in target organs of colorectal cancer metastasis express fibronectin, and that colorectal cancer tumour cells can bind fibronectin through integrin β6. This interaction is resistant to

Simultaneous Qualitative And Quantitative Identification Of Multiple Targets By Polymerase Chain Reaction On Microarray [PDF]

open access: yesChapter 12 at "Oligonucleotide Array Sequence Analysis", Nova Publishers, ISBN: 978-1-60456-542-3, 2008
An approach for multiplex qualitative and quantitative microarray-based PCR analysis has been proposed. The characteristics of PCR executed on a gel-based oligonucleotide microarray with immobilized forward primers and a single common reverse primer in solution were investigated for several DNA targets.

Competitive Reverse-Transcriptase Polymerase Chain Reaction without an Artificial Internal Standard

open access: yesAnalytical Biochemistry, 1995
Advances in our understanding of molecular and cellular physiology necessitate that mRNA levels for specific growth factors and other rare transcripts be measured quantitatively in small samples. Conventional methods such as Northern blot analysis and solution hybridization/ribonuclease protection are not sufficiently sensitive.

Rapid Diagnostic Testing for Infective Endocarditis and Myocarditis Using Nanopore Targeted Sequencing

open access: yesiLABMED, EarlyView.
This research presents a method based on nanopore targeted sequencing (NTS) with pathogen‐specific panels for testing infective endocarditis (IE) and myocarditis. The NTS achieved a detection limit of 20 copies/test for the IE target panel and 10 copies/test for the myocarditis target panel.

Pengembangan Sejumlah Primer untuk Reverse Transcriptase Polymerase Chain Reaction Guna Melacak Virus Flu Burung di Indonesia (DEVELOPMENt OF PRIMERS FOR REVERSE TRANSCRIPTASE POLYMERASE CHAIN REACTION TO DETECT AVIAN INFLUENZA VIRUS IN INDONESIA)

open access: yesJurnal Veteriner, 2016
Until recently, two clades of of avian influenza viruses (AIVs) designated as 2.3.2 and 2.2.3 havebeen circulating in Indonesia. Mutations of AIV genes have cretaed many more variants of the virus.

A Chemical Kinetic Model of Transcriptional Elongation [PDF]

open access: yesarXiv, 2006
A chemical kinetic model of the elongation dynamics of RNA polymerase along a DNA sequence is introduced. The proposed model governs the discrete movement of the RNA polymerase along a DNA template, with no consideration given to elastic effects. The model's novel concept is a ``look-ahead'' feature, in which nucleotides bind reversibly to the DNA ...
