Toshiba has developed a DNA chip for diagnosing rheumatism. The Tokyo-based firm developed the chip in collaboration with Professor Naoyuki Kamatani at Tokyo Women’s Medical University. The partners will start testing the efficacy of the chip next month.


SuperArray has launched its GEArray Expression Analysis Suite application software. The web-based software provides visual presentations of statistical data analyses, as well as reports of normalized intensities, present and absent calls, and color-coded fold changes.


BioDiscovery released version 2.7 of its GeneDirector microarray data management software, and version 6.0 of its ImaGene image analysis software. New features in GeneDirector 2.7 include integration with ImaGene 6.0 and with Agilent’s Bioanalyzer 2100 software, a new project organization feature, and an enhanced GUI. New features in ImaGene 6.0 include background correction and data normalization capability, differential regulation analysis, M-A and GenePie plots, and enhanced grid finding.


Following the recent publication of the first complete genome sequence of a tree, the DOE’s Joint Genome Institute has released a poplar genome browser at http://www.jgi.doe.gov/poplar. The Umeå Plant Science Center in Sweden has also released a database with Populus gene expression information at http://www.populus.db.umu.se.


PerkinElmer last week launched a new non-contact micro-dispensing system called Piezoarray. The system features a computer interface that is much easier to use than previous machines in designing custom array plates, according to the company.

Genome Sequences Reveal Range Mutations in Induced Pluripotent Stem Cells

Researchers in Nature Genetics detect somatic mutation variation across iPSCs generated from blood or skin fibroblast cell sources, along with selection for BCOR gene mutations.

Researchers Reprogram Plant Roots With Synthetic Genetic Circuit Strategy

Root gene expression was altered with the help of genetic circuits built around a series of synthetic transcriptional regulators in the Nicotiana benthamiana plant in a Science paper.

Infectious Disease Tracking Study Compares Genome Sequencing Approaches

Researchers in BMC Genomics see advantages for capture-based Illumina sequencing and amplicon-based sequencing on the Nanopore instrument, depending on the situation or samples available.

LINE-1 Linked to Premature Aging Conditions

Researchers report in Science Translational Medicine that the accumulation of LINE-1 RNA contributes to premature aging conditions and that symptoms can be improved by targeting them.
