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.

First insight into links between microbes and developing infant

A new multi-university study reports that differences in bacterial colonization of the infant gut in formula-fed and breast-fed babies lead to changes in the expression of genes involved in the infant's immune system.

Researchers identify novel base modification in RNA

Over the past decade, research in the field of epigenetics has revealed that chemically modified bases are abundant components of the human genome and has forced us to abandon the notion we've had since high school genetics that DNA consists of only four bases.

RAL proteins linked with aggressive cancer characteristics in human tumors

We have known for years that when the proteins RalA and RalB are present, cells in dishes copy toward aggressive forms of cancer. However, until this week, no study had explored the effects of RAL proteins in human cancers - an essential step on the path to developing drugs to target these proteins.

Breast cancer cell surface protein blows cover of potent tumor-generating cells

Breast cancer stem cells wear a cell surface protein that is part nametag and part bull's eye, identifying them as potent tumor-generating cells and flagging their vulnerability to a drug, researchers at The University of Texas MD Anderson Cancer Center report online in Journal of Clinical Investigation.

Molecular biomarkers in the lungs may be an additional predictive technique for cancer screening

The most recent research released in June's Journal of Thoracic Oncology says molecular biomarkers in the tissue and fluid lining the lungs might be an additional predictive technique for lung cancer screening.

Scientists identify and prioritize genes associated with schizophrenia

An Indiana University-led research team, along with a group of national and international collaborators, has identified and prioritized a comprehensive group of genes most associated with schizophrenia that together can generate a score indicating whether an individual is at higher or lower risk of developing the disease.

Galectin Therapeutics commences Phase 1/2 trial of new treatment combination for advanced MM

Galectin Therapeutics, the leader in developing carbohydrate-based therapeutic compounds to inhibit galectin proteins for the therapy of liver fibrosis and cancer, today announced that the first patient has been dosed in a Phase 1/2 trial evaluating the safety and efficacy of a novel treatment combination for the treatment of advanced metastatic melanoma.

Genetic test can accurately predict spread of eye cancer

Researchers at Washington University School of Medicine in St. Louis have developed a genetic test that can accurately predict whether the most common form of eye cancer will spread to other parts of the body, particularly the liver.

Researchers identify new biomarker and therapeutic target for pancreatic cancer

Researchers at the University of California, San Diego School of Medicine and Moores Cancer Center have identified a new biomarker and therapeutic target for pancreatic cancer, an often-fatal disease for which there is currently no reliable method for early detection or therapeutic intervention. The paper will be published May 15 in Cancer Research.

Study identifies how skeletal muscle stem cells respond to muscle injury

A study conducted by Children's Hospital & Research Center Oakland scientists identifies how skeletal muscle stem cells respond to muscle injury and may be stimulated to improve muscle repair in Duchenne Muscular Dystrophy, a severe inherited disease of muscle that causes weakness, disability and, ultimately, heart and respiratory failure.

Lung cancer molecular subtypes correlate with genetic alterations, patient's response to therapy

Cancer therapies targeting specific molecular subtypes of the disease allow physicians to tailor treatment to a patient's individual molecular profile. But scientists are finding that in many types of cancer the molecular subtypes are more varied than previously thought and contain further genetic alterations that can affect a patient's response to therapy.

Chromatin compaction required for proper embryonic stem cell differentiation

New research findings show that embryonic stem cells unable to fully compact the DNA inside them cannot complete their primary task: differentiation into specific cell types that give rise to the various types of tissues and structures in the body.

NCSU scientists use light-activated molecules to turn gene expression on and off

Imagine being able to control genetic expression by flipping a light switch. Researchers at North Carolina State University are using light-activated molecules to turn gene expression on and off. Their method enables greater precision when studying gene function, and could lead to targeted therapies for diseases like cancer.

Study describes new family of six genes that control mitochondrial transport in neurons

A team headed by Eduardo Soriano at the Institute for Research in Biomedicine (IRB Barcelona) has published a study in Nature Communications describing a new family of six genes whose function regulates the movement and position of mitochondria in neurons.

Scientists develop new method to directly identify miRNA targets in cells

Human cells are thought to produce thousands of different microRNAs (miRNAs)-small pieces of genetic material that help determine which genes are turned on or off at a given time. miRNAs are an important part of normal cellular function, but they can also contribute to human disease-some are elevated in certain tumors, for example, where they promote cell survival.

Botanical formula inhibits breast to lung cancer metastasis in mice

Scientists at Indiana University Health's Cancer Research Laboratory have found that a sophisticated botanical formula slows human breast cancer growth and inhibits breast to lung metastasis in mice. The formula contains extracts from medicinal mushrooms, medicinal herbs and purified nutritional compounds, and showed no toxic side-effects.

Study: Y and W chromosomes are very important in fertility

The study, published yesterday in the journal Proceedings of the National Academy of Sciences (PNAS), looked at how genes on sex-linked chromosomes are passed down generations and linked to fertility, using the specific example of the W chromosome in female chickens.

iBio receives U.S. patent for iBioModulator platform

iBio, Inc. today announced issuance of a US patent covering compositions of matter and methods of use of modified lichenase B polypeptides comprising the Company's iBioModulator platform.

Molecule that starts DNA repairs also halts them

Repairing DNA breaks can save a cell's life - but shutting off the repair machinery can be just as critical. How cells accomplish this feat was unknown. However, new research by Johns Hopkins scientists, published in the Feb. 22 issue of Nature, suggests that shutting down the repair machinery relies heavily on the same molecule used to start repair in the first place.

Research grants on facioscapulohumeral dystrophy prove useful as genetic basis is found

Businessman Bill Moss’s determination to fight his untreatable muscle-wasting disease may have paid off. Four years ago, Mr Moss, a former Macquarie Bank Executive Director, established a charitable research foundation, FSHD Global, which partly funded the Italian researchers who made the breakthrough.
