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.

Scientists identify signals that regulate the formation of spinal marrow

A team of researchers at Umea University in Sweden under the leadership of Thomas Edlund, Umea Center for Molecular Medicine, is now publishing their discovery of the signal molecules that regulate the formation of spinal marrow during the fetal period.

Cell survival depends on chromosome integrity

UCLA researchers report that thousands of genes behave differently in the same organs of males and females - something never detected to this degree.

New diagnostic approach for carriers of recessive genetic disorders

Scientists Vivian Cheung and Warren Ewens from the University of Pennsylvania have developed a new approach for the diagnosis of medical disorders that are inherited in a recessive manner.

Liver cancer is likely caused by cycles of liver cell death and renewal

Research at the University of California, San Diego (UCSD) School of Medicine shows that liver cancer is likely caused by cycles of liver cell death and renewal.

3 new genes implicated in rheumatoid arthritis

Researchers continue to search for genetic clues into rheumatoid arthritis (RA), a chronic inflammatory joint disease.

Stem cells contain immortal DNA

EuroStemCell scientists at the Pasteur Institute in Paris have demonstrated one of the body's most sophisticated ways of regulating the genetic material of stem cells.

In vitro fertilisation could be causing genetic errors in embryo

The conditions in which embryos are cultured in the laboratory during in vitro fertilisation could be causing genetic errors that are associated with certain developmental syndromes and other abnormalities in growth and development, such as low birth weight.

New roles for growth factors

During embryonic development, nerve cells hesitantly extend tentacle-like protrusions called axons that sniff their way through a labyrinth of attractive and repulsive chemical cues that guide them to their target.

From DNA to RNA to protein

Of the thousands of proteins produced in our cells, few are as important as the enzyme RNA polymerase (RNAP), which has the unique ability to faithfully copy genetic information from DNA.

Fly research sheds light on sleep regulation and its role in memory

Researchers at the University of Pennsylvania School of Medicine have discovered that a brain region previously known for its role in learning and memory also serves as the location of sleep regulation in fruit flies.

Researchers identify new keys to regulation of bacterial gene expression

The cellular process of transcription, in which the enzyme RNA polymerase constructs chains of RNA from information contained in DNA, depends upon previously underappreciated sections of both the DNA promoter region and RNA polymerase

Burkitt lymphoma gene expression signature identified

An international research study involving the University of Nebraska Medical Center, the National Cancer Institute and 10 other institutions has successfully identified the gene expression signature for Burkitt lymphoma.

Scientists watch the behavior of a single gene in real time

Scientists at the Albert Einstein College of Medicine of Yeshiva University have observed for the first time that gene expression can occur in the form of discrete "pulses" of gene activity.

Protein called Elk-1appears to play role in neurodegeneration and schizophrenia

Pprotein called Elk-1 interacts with mitochondria, the energy storehouse of a cell, suggesting that this protein - typically active in the nucleus - could play a role in cell death and mitochondria-related diseases such as neurodegeneration and schizophrenia.

Discovery of new defect in artery growth

From the beginning, arteries and veins are different in the way they branch into vascular networks, say Dartmouth heart researchers.

Black women have fewer breast cancers than white women, but their mortality is worse

For decades, researchers have tried to understand why breast cancer in younger black women is such a significant public health problem.

7 Jun 2006

Gene mutation potentially involved in breast cancer initiation

Researchers have found evidence suggesting that a mutation in a gene that normally helps block the formation of breast tumors could play a role in the initiation of a major form of breast cancer.

Type 1 diabetes results from selective destruction of pancreatic islet beta cells

IDDM, which used to be referred to as Type 1 diabetes, results from selective destruction of insulin-producing pancreatic islet beta cells by the body's immune system.

Potential novel treatment strategy for Ewing's sarcoma

Using molecular and cell-based models, researchers at Georgetown University Medical Center have refined the picture of how a cancer-promoting protein associated with Ewing's sarcoma functions.

Exposure to environmental estrogens during development of the prostate gland in the male fetus may lead to later prostate cancer risk

A study in the June 1 issue of Cancer Research presents the first evidence that exposure to low doses of environmental estrogens during development of the prostate gland in the male fetus may result in a predisposition to prostate cancer later in life.
