Hydroxymethylation profile of cell-free DNA is a biomarker for early colorectal cancer.

Early detection of cancer will improve survival rates. The blood biomarker 5-hydroxymethylcytosine has been shown to discriminate cancer. In a large covariate-controlled study of over two thousand individual blood samples, we created, tested and explored the properties of a 5-hydroxymethylcytosine-based classifier to detect colorectal cancer (CRC).

New Fpg probe chemistry for direct detection of recombinase polymerase amplification on lateral flow strips.

Rapid, cost-effective and sensitive detection of nucleic acids has the ability to improve upon current practices employed for pathogen detection in diagnosis of infectious disease and food testing. Furthermore, if assay complexity can be reduced, nucleic acid amplification tests could be deployed in resource-limited and home use scenarios. In this study, we developed a novel Fpg (Formamidopyrimidine DNA glycosylase) probe chemistry, which allows lateral flow detection of amplification in undiluted recombinase polymerase amplification (RPA) reactions.

Expression and purification of functional JNK2beta2: perspectives on high-level production of recombinant MAP kinases.

The mitogen-activated protein (MAP) kinases are a group of serine/threonine kinases that mediate intracellular signal transduction in response to environmental stimuli including stress, growth factors, and various cytokines. Of this family, the c-Jun N-terminal kinases (JNKs) are members which, depending on cell type, have been shown to activate the transcription of genes involved in the inflammatory response, apoptosis, and hypertrophy. Here we report the use Baculovirus/Sf9 cells to produce milligram quantities of recombinant JNK2beta2 substrate which could be purified to >90% as judged by SDS-PAGE.
