NIH researchers identify striking genomic signature shared by five types of cancer

Read moreNational Institutes of Health researchers have identified a signature in tumor DNA that occurs in five different types of cancer. They also found evidence that this methylation signature may be present in many more types of cancer. The specific signature results from a chemical modification of DNA called methylation. Researchers hope to spur development of a blood test that can be used to diagnose a variety of cancers at early stages. The study appears today, February 5, 2016, in The Journal of Molecular Diagnostics. Read more 


NIH genome sequencing program targets the genomic bases of common, rare disease

Read moreBethesda, Md., Thurs., Jan. 14, 2016 - The National Institutes of Health will fund a set of genome sequencing and analysis centers whose research will focus on understanding the genomic bases of common and rare human diseases. The National Human Genome Research Institute (NHGRI), part of NIH, today launched the Centers for Common Disease Genomics (CCDG), which will use genome sequencing to explore the genomic contributions to common diseases such as heart disease, diabetes, stroke and autism.

The "bunny ear" hypothesis: How defective DNA looping may contribute to cancer

Read moreYour DNA forms thousands of loops, like those of a shoelace. Just as you learned to tie your shoes by forming separate "bunny ear" loops of string, your DNA forms many of these loops to create "genetic neighborhoods" within each bunny ear loop. These neighborhoods bring distant genes and specific gene control switches into close proximity. Genetic neighborhoods can be autonomous and remain separate from other neighborhoods. The December Genome Advance of the Month highlights a landmark study in Nature that describes what happens when two genetic neighborhoods merge in brain tumor cells.   Read more
