In recent interviews, J&J officials spoke about ongoing work to further develop its technology for circulating tumor cells to include characterization capabilities, and its new center of excellence for companion diagnostics to leverage partnerships with other diagnostic firms.

The microRNA has been shown to suppress a protein important for the generation of high-density lipoprotein and for the removal of of cholesterol from peripheral tissues, according to the company.

The researchers used digital gene-expression profiling to identify an abundance of satellite repeats, which are linked to gene silencing and chromosome maintenance and could potentially be used as biomarkers for early diagnosis of cancer.

The partners will develop a bench-top platform to isolate and explore the biology of rare cells at the protein, RNA, and DNA levels.

The partners will develop pharmacogenomic assays based on Mass General's genotyping platform.

The UK-based firm will provide Sanger with more than 200 genetically defined cell lines with cancer-causing mutations, which will guide researchers working on the Genomics of Drug Sensitivity in Cancer project.

The method, called low-quantity digital gene expression, or LQ-DGE, was published online last week in Nature Methods. Helicos said it is currently assessing the technique for its "potential to advance molecular diagnostic assays for patients suffering from breast and ovarian cancer."

Athena alleges that Ambry's sale of tests for certain types of diabetes infringes on patents that Athena licensed from its development partner Correlagen.

The 2007 survey, conducted by the MGH Institute for Health Policy, also suggests that academic life scientists with industry support withheld data or delayed publication due to commercial prospects more frequently than those with no industry support during that time.

Using an siRNA screen, a team of researchers from Boston and Maryland has identified a host of human proteins that appear to play a role in hepatitis C infection.


At the Lancet, more than two dozen public health researchers condemn the conspiracy theories that have emerged surrounding the source of the COVID-19 outbreak.

The Washington Post reports that Philip Leder, who helped uncover how DNA codes for proteins and studied the role of genes in cancer, has died.

Researchers from Trinity College Dublin and the University of Pittsburgh look into how often de novo genes arise and how important they may be.

In Nucleic Acids Research this week: pipeline for genotyping Alu retrotransposon mobile element insertions, previously undocumented non-coding RNAs, and more.
