Gene Expression News and Research

RSS

Gene Expression is the process by which a gene gets turned on in a cell to make RNA and proteins. Gene expression may be measured by looking at the RNA, or the protein made from the RNA, or what the protein does in a cell.

New technique to deliver gene therapy to soft-tissue tumors

Using new research and technology that shows bone marrow-derived mesenchymal stem cells (MSCs) will engraft at the site of a tumor and contribute to the growth of stromal fibroblasts (the healthy tissue surrounding a tumor)

Researchers profile over 6000 genes in the two primary types of normal breast cells

For several years, scientists have attempted to identify gene expression changes, using microarrays or ‘DNA chips’, in order to understand and predict breast cancer onset, progression, and clinical outcome.

A new prognostic marker has shown potential to predict recurrence in certain colon cancer patients

In the study, a team of researchers led by Veridex, LLC, a Johnson & Johnson company, used gene expression profiling to identify the new marker – a 23-gene signature – which may predict disease recurrence in patients initially diagnosed with Dukes' B colon cancer.

Scientists have unraveled the behavior of one key component of bacteria

The researchers studied a mechanism of action they call the "magic spot" – an important regulator of gene expression. They describe their results in the current issue of the journal Cell.

Scientists identify six genes associated with the most common form of non-Hodgkin's lymphoma

In a paper that will be published on Thursday, April 29, 2004 in the New England Journal of Medicine, a team of scientists from Stanford University and Applied Biosystems, an Applera Corporation business, describe the identification of six genes associated with survival in diffuse large B cell lymphoma (DLBCL), the most common form of non-Hodgkin's lymphoma.

New analytical approach that combines genetic and clinical data to give individualized prognosis of cancer recurrence

Researchers at Duke University have developed a new analytical approach that combines genetic and clinical data to give cancer patients an individualized prognosis of their cancer recurrence. The information could prove critical in deciding how aggressively to treat the disease following surgery.

Free software helps capture the molecular signatures of cells

A new, free software package developed by the Broad Institute of MIT and Harvard makes it easier and faster for scientists to capture the molecular signatures of cells in a particular state--information that's crucial to disease diagnosis and prognosis.

Molecular analyses of leukemia patients suggest strategies for better treatments

The cure rate for pediatric acute lymphoblastic leukemia (ALL) might continue to rise with improved use of conventional therapies. But even more effective and less toxic therapies based on genetic and pharmacogenetic studies might one day push the success rate close to 100 percent, according to an article published by investigators at St. Jude Children’s Research Hospital in the April 8 issue of the New England Journal of Medicine.

New research findings in study of Rett Syndrome

Rudolf Jaenisch of the Whitehead Institute of Biomedical Research in Cambridge, MA reports in the April 6, 2004 online issue of the Proceedings of the National Academy of Sciences that introduction of the MeCP2 protein into post-mitotic nerve cells of MeCP2 mutant mice rescues the symptoms of Rett Syndrome. This raises the possibility that neurons are functionally normal in a newborn child and that neural dysfunction manifests itself only later due to prolonged MeCP2 deficiency. If correct, therapeutic strategies aimed at preventing the onset of Rett symptoms could be initiated at birth.

Zebrafish show effects of ionizing and UV radiation differ during embryo development

Adam Dicker, M.D., Ph.D., associate professor of radiation oncology at Jefferson Medical College of Thomas Jefferson University and Jefferson’s Kimmel Cancer Center in Philadelphia, Mary Frances McAleer, M.D., Ph.D., a resident in the Department of Radiation Oncology at Jefferson Medical College and their co-workers compared the effects on zebrafish embryos of two types of radiation – ionizing radiation, which is the kind given to patients for cancer treatment, and ultraviolet (UV) radiation, which comes naturally from the sun.

Discovery of novel gene profile that may identify colon stem cells

Researchers at Jefferson Medical College have uncovered a novel pattern of gene expression in the stem cell-rich bottom of tiny “crypts” in the tissue lining the colon. By identifying these patterns, the scientists hope to be able to identify mechanisms through which stem cells contribute to the development of colon cancer.

Extraction of RNA from Archived Formalin-Fixed, Paraffin-Embedded Tissue

For the first time, Fox Chase Cancer Center researchers have demonstrated the ability to extract RNA from formalin-fixed, paraffin-embedded tissue samples archived for up to five years. What's more, the technology used retrieves high-quality samples, allowing researchers to identify cancer-related genetic changes. Accepted as a "late-breaking" abstract, the research was presented today at the 95th Annual Meeting of the American Association for Cancer Research by Renata Coudry, M.D., a research pathologist at Fox Chase Cancer Center.

World’s largest biotechnology company acquires Tularik

Amgen Inc., the world’s largest biotechnology company, and Tularik Inc., a pioneer in drug discovery related to cell signaling and the control of gene expression, today jointly announced that they have signed a definitive merger agreement whereby Tularik will become a wholly-owned subsidiary of Amgen in a stock for stock transaction.

New research to predict patient response to cancer chemotherapies

Timothy J. Yeatman, M.D., Moffitt's Associate Center Director for Clinical Investigations at the H. Lee Moffitt Cancer Center & Research Institute, and the Sarasota-based DNAPrintTM genomics, Inc., have formed a joint research program to develop and implement new clinical tests for predicting patient response to cancer chemotherapies.

Renowned researchers, scientists share advances in prevention, diagnosis, therapy

Leading researchers are gathering today for the 95th Annual Meeting of the American Association for Cancer Research (AACR), the premier multidisciplinary assembly, which features the latest developments in basic, prevention, translational and clinical cancer research. The meeting occurs from March 27 – 31, 2004 at the Orlando Convention Center, Fla.

Researchers discover new form of the Rett syndrome protein

Adrian Bird and Skirmantas Kriaucionis of the University of Edinburgh have discovered a novel form of the protein MeCP2. This alternate form, coined MeCP2 alpha, differs from the original only in the first 19 amino acids. Interestingly, Adrian Bird, Director of the Welcome Trust Centre for Cell Biology at Edinburgh University, found that MeCP2 alpha, is ten times more prevalent not only in the brain but also in other tissues. These findings are currently reported online in Nucleic Acids Research. Similar findings were reported yesterday in Nature Genetics online by Berge Minassian, a neurologist and scientist at Toronto's Hospital for Sick Children.

Researchers find link that could aid in treatment of kidney cyst diseases

Researchers at UT Southwestern Medical Center at Dallas have uncovered a link between two cyst-forming diseases that affect the kidneys, a finding that could lead to treatments for both a rare form of diabetes and a common kidney disease.

New Theory About Alzheimer's Disease

A group of scientists at The Scripps Research Institute has proposed a new theory about the cause of Alzheimer's disease, the progressive neurodegenerative disorder that currently afflicts some 4.5 million Americans. According to the hypothesis, the disease arises as a consequence of inflammation, which creates abnormal metabolites out of normal brain molecules.
