1. Lessons in wood formation from Arabidopsis
   03-01-2007 · EurekAlert!
   In two separate studies published in The Plant Cell, researchers identify key transcription factors that control the expression of genes related to secondary wall formation in the model herbaceous plant Arabidopsis. The presence of similar genes and pathways in tree species suggests that they may play a role in the regulation of wood formation in trees.

   Most of the big differences between human and chimpanzee DNA lie in regions that do not code for genes, according to a new study. Instead, they may contain DNA sequences that control how gene-coding regions are activated and read.

   11-21-2006 · Massachusetts Institute of Technology (MIT)
   Researchers have found that a class of RNA molecules previously thought to have no function may in fact protect sex cells from self-destructing. Central to this discovery is the fundamental process of gene expression.

   Decaffeinated coffee plants, pest-resistant cotton, and Vitamin A-producing rice varieties have all been developed by introducing genes into plants. Scientists also create modified plants to identify and characterize the functions of specific genes. The current issue of Cold Spring Harbor Protocols -- released online today -- includes a set of techniques for the creation of transgenic plants.

5. AVN944 inhibits IMPDH & induces apoptosis-related biomarkers in patients with hematologic cancers
   12-11-2006 · EurekAlert!
   IMPDH is highly upregulated in most hematological cancers and solid tumors -- an essential role in cancer cell synthesis of DNA and RNA. Inhibition of IMPDH represents a new and important approach to treat cancer. In a Phase I trial of AVN944, AvalonRx identified a set of 34 genes. These gene markers correlate with the biochemical effects of AVN944 on protein function -- believed to result in tumor cell apoptosis at the right doses.

7. Largest genomic search finds genes that may contribute to autism
   02-18-2007 · EurekAlert!
   An international team of researchers from 19 countries has identified one gene and previously unidentified region of another chromosome as the location of another gene that may contribute to a child's chances of having autism.

8. New protein implicated in autism
   03-22-2007 · EurekAlert!
   Autism is a common neurodevelopmental disorder characterized by severely impaired social, communicative, and behavioral functions. Although several genes are associated with autism, none lie in the region of human chromosome 7 associated with autism susceptibility. Now, a new study demonstrates that mice lacking CADPS2, which is encoded by a gene in the autism susceptibility region of human chromosome 7, exhibit autistic-like characteristics, leading to the suggestion that CADPS2 defects might predispose individuals to autism.

9. Newly identified mechanism for silencing genes points to possible anti-cancer strategies
   05-16-2007 · EurekAlert!
   Scientists are only beginning to appreciate the extraordinary degree of control exercised over every step of the gene-to-protein production process. Only about 10 percent of human genes, for example, are active in a given cell at a given time, with the remaining 90 percent silenced by a various mechanisms. In a just-published study in Nature, scientists report an important new gene-silencing mechanism that points to promising potential targets for anti-cancer interventions.

10. Gene expression patterns predict rapid decline in idiopathic pulmonary fibrosis patients
    05-30-2007 · EurekAlert!
    University of Pittsburgh researchers have identified a specific genetic profile in a group of idiopathic pulmonary fibrosis (IPF) patients that indicates a far more rapid progression to complete pulmonary failure and death without a lung transplant in comparison with other patients. In collaboration with pulmonary scientists in Mexico and California, Pittsburgh researchers found 437 differentially expressed genes. Most IPF patients live about five years following diagnosis with the chronic lung disease.
