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.

Two studies shed new light on nature of tandem DNA repeat arrays

A pair of studies by a team of scientists has shed new light on the nature of a particular type of DNA sequences—tandem DNA repeat arrays—that play important roles in transcription control, genome organization, and development.

Multinational study suggests new way to classify gliomas

A comprehensive analysis of the molecular characteristics of gliomas—the most common malignant brain tumor—explains why some patients diagnosed with slow-growing (low-grade) tumors quickly succumb to the disease while others with more aggressive (high-grade) tumors survive for many years.

Eisai's Halaven receives FDA approval for treatment of patients with metastatic liposarcoma

Eisai Inc. announced today that the U.S. Food and Drug Administration approved Halaven (eribulin mesylate) Injection (0.5 mg per mL) for the treatment of patients with unresectable or metastatic liposarcoma who have received a prior anthracycline-containing regimen.

New NYUCD study explores how gene expression initiated in notochord

A new study by basic science researchers in the Department of Basic Science and Craniofacial Biology at New York University College of Dentistry sought to understand how gene expression is initiated in the notochord, the evolutionary and developmental precursor of the backbone.

CNIO team uses network theory to build and study first epigenetic communication network

One of the big questions for which there is still no clear answer in biology is how, based on the four universal letters that make up DNA, it is possible to generate such different organisms as a fly or a human, or the different organs and tissues they comprise. In recent years, researchers have discovered that the system is much more complicated than was originally thought.

Scientists discover epigenetic switch linked to obesity

It is well known that a predisposition to adiposity lies in our genes. A new study by researchers at the Max Planck Institute of Immunobiology and Epigenetics in Freiburg now shows that it is also crucial how these genes are regulated. The scientists led by Andrew Pospisilik discovered a novel regulatory, epigenetic switch, which causes individuals with identical genetic material, such as monozygotic twins, to either be lean or obese.

Researchers identify cells that likely give rise to Group 4 medulloblastoma

Researchers have identified the cells that likely give rise to the brain tumor subtype Group 4 medulloblastoma. The finding removes a barrier to developing more effective targeted therapies against the brain tumor's most common subtype.

Brain-derived neurotrophic factor linked to slower cognitive decline in older people

Older people with higher amounts of a key protein in their brains also had slower decline in their memory and thinking abilities than people with lower amounts of protein from the gene called brain-derived neurotrophic factor, or BDNF, according to a study published in the January 27, 2016, online issue of Neurology, the medical journal of the American Academy of Neurology.

DNA imprinting defect may affect children diagnosed with osteosarcoma

Children diagnosed with osteosarcoma may be impacted by a DNA imprinting defect also found in parents, according to new research from the Masonic Cancer Center, University of Minnesota. DNA imprinting is a phenomenon in which just one of the two inherited genes is active while the other is present but inactive.

Specific genetic pattern in the womb could predict IVF treatment outcome

Fertility experts in Southampton and the Netherlands have identified a specific genetic pattern in the womb that could predict whether or not IVF treatment is likely to be successful.

Sensitive computational method could help reveal effect of the immune system on cancer

A study by researchers at Norris Cotton Cancer Center has shown that a very sensitive computational method can be used to reveal the human immune system's effect on cancer. The Dartmouth study was the first to perform an in-depth computational examination of how immune activity translates to prognosis in breast cancer.

Colon cancer patients lacking CDX2 protein more likely to benefit from chemotherapy

Using a new computer science approach, researchers at University of California, San Diego School of Medicine, Columbia University and Stanford University discovered a distinctive molecular feature — a biomarker — that identified colon cancer patients who were most likely to remain disease-free up to five years after surgery.

New machine-learning technique could be used to uncover previously unknown features of organisms

A powerful new machine-learning technique can be applied to large datasets in the biological sciences to uncover previously unknown features of organisms and their genes, according to a team led by researchers from the Perelman School of Medicine at the University of Pennsylvania.

Duke researchers closer to developing rapid blood test for bacterial and viral infections

Researchers at Duke Health are fine-tuning a test that can determine whether a respiratory illness is caused by infection from a virus or bacteria so that antibiotics can be more precisely prescribed.

Study outlines new model to help predict age-related response to hepatitis B vaccine

Physicians have known for years that patients respond differently to vaccines as they age. There may soon be a new way to predict and enhance the effectiveness of vaccinations, in particular the hepatitis B vaccine.

Novel gene therapy treatment proves safe, effective for factor VII deficiency

A single injection. That's all someone with a factor VII deficiency would need for a life-long cure, thanks to a new gene therapy treatment developed in a collaboration of researchers at the University of North Carolina and The Children's Hospital of Philadelphia.

Researchers reveal biological connection between obesity and colorectal cancer risk

Obesity has long been associated with increased risk of colorectal cancer, but the link has never been understood. Now, a research team led by investigators at Thomas Jefferson University has revealed the biological connection, and in the process, has identified an approved drug that might prevent development of the cancer.

Researchers reveal totally new biological mechanism that underlies cancer

In a landmark study, researchers from the Broad Institute and Massachusetts General Hospital reveal a completely new biological mechanism that underlies cancer. By studying brain tumors that carry mutations in the isocitrate dehydrogenase (IDH) genes, the team uncovered some unusual changes in the instructions for how the genome folds up on itself.

New mechanism of differentiation may offer novel therapeutic approaches to blood malignancies, solid tumors

In humans the differentiation of stem cells into hundreds of specialized cell types is vital. Differentiation drives development from fertilized egg to a newborn, and it underlies the continuous replacement of the 5 billion cells that die every hour in an adult. On the downside, mutations in differentiation pathways of different cell types can be drivers of cancers.

IMB scientists identify two proteins vital for demethylation of DNA

Scientists at the Institute of Molecular Biology in Mainz have identified a missing piece of the puzzle in understanding how epigenetic marks are removed from DNA. The research on DNA demethylation sheds new light on a fundamental process that is important in development and diseases such as cancer.
