exon arrays

In Genome Research this week: molecular autopsies for sudden death, telomere methylation in Arabidopsis, and more.

Longtime array rivals Affymetrix and Illumina last week introduced new chips targeting the exome, exonic variants in the protein-coding regions of the human genome.

The researchers found that treatment with lactate and ketones causes cancer cells to express gene profiles associated with “stemness.” They believe that these gene signatures could, in turn, predict poor clinical outcome in breast cancer patients.

The new arrays, scheduled to launch later this month, will enable researchers to examine alternately expressed exons, and are in line with Agilent's effort to build its portfolio in the gene expression market.

In a survey, about half of Canadian government scientists say they still feel as though they cannot speak freely, ScienceInsider reports.

Clinicians in China are moving ahead with a number of CRISPR trials, NPR reports, as the US embarks on its first.

The Atlantic reports that biohacker Josiah Zayner regrets injecting himself with the CRISPR gene-editing tool on stage.
