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 nucleotide could revolutionize epigenetics

Anyone who studied a little genetics in high school has heard of adenine, thymine, guanine and cytosine - the A,T,G and C that make up the DNA code.

New clues to how stem cells form

An Emory University study shows some of the first direct evidence of a process required for epigenetic reprogramming between generations – a finding that could shed more light on the mechanisms of fertilization, stem-cell formation and cloning.

Conserved gene expression reveals our 'inner fish'

A study of gene expression in chickens, frogs, pufferfish, mice and people has revealed surprising similarities in several key tissues.

Molecule Thymosin beta-4 prompts damaged heart cells to repair themselves after a heart attack

A protein that the heart produces during its early development reactivates the embryonic coronary developmental program and initiates migration of heart cells and blood vessel growth after a heart attack, researchers at UT Southwestern Medical Center have found.

New understanding of roles of insulin in obesity or type II diabetes

Researchers have uncovered new evidence suggesting factors other than genes could cause obesity, finding that genetically identical cells store widely differing amounts of fat depending on subtle variations in how cells process insulin.

Synthetic green-glowing genes show how 'silent' mutations influence protein production

Biologists at the University of Pennsylvania have revealed a hidden code that determines the expression level of a gene, providing a way to distinguish efficient genes from inefficient ones.

New approach for surveying phosphorylation

Scientists have developed a new approach for surveying phosphorylation, a process that is regulated by critical cell signaling pathways and regulates several key cellular signaling events.

Discovery of key decision-point at which cells with broken DNA repair themselves or die

When cells undergo potentially catastrophic damage, for example as a result of exposure to ionizing radiation, they must make a decision: either to fix the damage or program themselves for death, a process called apoptosis.

Genetic variation found to increase risk of schizophrenia

Rutgers geneticist Linda Brzustowicz and her colleagues have identified a specific DNA change that is likely to increase risk for developing schizophrenia in some people.

Rare window on spinal muscular atrophy genetics

Caused by a mutation of the SMN gene, spinal muscular atrophy (SMA) is an infantile and juvenile neurodegenerative disorder where motor neuron loss causes progressive paralysis.

Biomarker associated with poor outcome in aggressive childhood cancer

Results from a new study identify a biomarker that may be useful for predicting the outcome of treatment for neuroblastoma, the most common cancer in young children.

New research to study genetics and cell biology of pancreatic cancer

The Georgia Institute of Technology and Saint Joseph's Hospital have joined together to begin the first regional research program to study the genetics and cell biology of pancreatic cancer.

New technique for carrying out gene-expression profiling

A novel technique for carrying out gene-expression profiling is set to challenge the market dominance of the current, widely used methodology, reports Genetic Engineering & Biotechnology News (GEN).

Researchers develop mouse models of leukemia that predict response to chemotherapy

Being able to accurately predict how a given cancer will respond to chemotherapy would spare patients with non-responsive tumors the burden of undergoing toxic and ultimately unhelpful treatment.

Amniotic fluid may be a new source of stem cells

For the first time, scientists have shown that amniotic fluid (the protective liquid surrounding an embryo) may be a potential new source of stem cells for therapeutic applications. The study was prepublished online on February 12, 2009, in Blood, the official journal of the American Society of Hematology.

Moonlighting immune molecules found in the brain

Molecules assumed to be in the exclusive employ of the immune system have been caught moonlighting in the brain - with a job description apparently quite distinct from their role in immunity.

A genetic technique to distinguish benign moles from malignant melanomas

A UCSF research team has developed a technique to distinguish benign moles from malignant melanomas by measuring differences in levels of genetic markers.

Mutations in a gene may stunt lung development in children

Mutations in a gene may cause poor lung development in children, making them more vulnerable to diseases such as chronic obstructive pulmonary disease (COPD) later in life, say researchers at the University of Pittsburgh Graduate School of Public Health and the German Research Center for Environmental Health.

Ovarian cancers detected early may be less aggressive, questioning effectiveness of screening

The biology of ovarian cancers discovered at an early stage may render them slower growing and less likely to spread than more aggressive cancers, which typically are discovered in an advanced stage, according to a study led by investigators in the Duke Comprehensive Cancer Center.
