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.

Study opens up new treatment possibilities for Wilms' tumor

As an embryo develops, its cells must learn what to do with the thousands of genes they've been equipped with. That's why each cell comes with a detailed gene-expression manual outlining exactly which genes should be switched on, to what extent, and when.

Researchers identify frequent technical bias in data generated by RNA-seq technology

Reproducibility of research data is a major challenge in experimental biology. As data generated by genomic-scale techniques increases in complexity, this concern is becoming more and more worrisome.

Scientists develop computationally inspired method for preclinical study of anxiety

Nearly 40 million people in the U.S. have an anxiety disorder. While treatment options exist, treatment success varies, and many people do not respond to treatment until weeks or months after they begin anti-depressants

IU scientists discover that beta-carophyllene improves wound healing

Indiana University researchers have discovered that a chemical compound found in essential oils improves the healing process in mice when it is topically applied to a skin wound -- a finding that could lead to improved treatments for skin injuries in humans.

Moffitt researchers develop efficient method for creating mouse models to study melanoma

Genetically engineered mouse models are often used by scientists to study how the addition, deletion or mutation of genes affects the development of disease and effects of drugs.

Researchers identify novel genetic signature with prognostic value for certain breast cancers

Researchers have identified a genetic signature with prognostic value for certain kinds of breast cancer. The discovery also contributes to a better understanding of the molecular mechanisms of pathological angiogenesis, the aberrant proliferation of blood vessels that occurs during cancer and other diseases.

Targeting specific nuclear transport systems may lead to possible therapeutic strategies for cancer

Although less often the focus of cancer research, recent studies have hinted at the possible importance of a type of protein known as nuclear transport receptors.

Stroke drug improves stem cell therapy in rat spinal cord injury models

Four months after treating them, Yasuhiro Shiga, MD, PhD, checked on his rats. Walking into the lab, he carried minimal expectations.

Researchers identify novel genes associated with severity of peanut allergy

Researchers at the Icahn School of Medicine at Mount Sinai have identified novel genes associated with the severity of peanut allergy, as well as ways in which these genes interact with other genes during allergic reactions.

Molecular subtyping of bladder tumors outperformed by standard pathology tests

While trying to develop a comparatively easy, inexpensive way to give physicians and their patients with bladder cancer a better idea of likely outcome and best treatment options, scientists found that sophisticated new subtyping techniques designed to do this provide no better information than long-standing pathology tests.

Perinatal exposure of rats to flame retardants changes the liver epigenome

Studies have shown that perinatal exposure of rats and mice to common flame retardants found in household items permanently reprograms liver metabolism, often leading later in life to insulin resistance and non-alcoholic fatty liver disease.

Discovery of novel mechanism by which certain breast cancers can metastasize

Researchers from the Baylor College of Medicine and Harvard Medical School have found a novel mechanism to explain the resistance of certain breast cancers that spread in the major organs of the body. They hope that this would help develop new therapeutic strategies to treat the cancer.

Scientists develop an approach to vaccinate against gut inflammation

Inflammatory bowel disease (IBD) is an umbrella term that describes many disorders that involve chronic inflammation of the digestive tract, including ulcerative colitis and Crohn's disease. These conditions are tied to certain alternations in the gut flora.

Gut disease and gene analysis networks

Gut diseases are difficult to diagnose in many cases, and their underlying dysfunction is hard to understand in many cases. Now, a new study published in the journal Molecular Omics promises to uncover a better insight into how these conditions occur and their mechanisms, by providing a deeper look at how genes interact in complex ways in health and fail to do so in disease.

Epigenome editing could repair genetic brain disorder

A new study published in the journal Nature Communications shows that it may be possible to reverse gene mutations that cause brain disorders, using a very precisely targeted epigenome editing technique. This type of gene editing does not change the gene’s DNA sequence itself but is focused on correcting epigenome changes only. The condition that was corrected in the study is called the WAGR syndrome and is associated with obesity and intellectual disability in people.

Study could help improve GENUS to become a therapeutic approach for Alzheimer's disease

The sweeping extent to which increasing 40Hz "gamma" rhythm power in the brain can affect the pathology and symptoms of Alzheimer's disease in mouse models has been surprising, even to the MIT neuroscientists who've pioneered the idea. So surprising, in fact, they can't yet explain why it happens.

Modifier gene offers a likely explanation for less infection in some patients with cystic fibrosis

Cystic fibrosis is caused by an inherited mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene.

A network approach to explore the causes of IBD

Diseases of the gut are often notoriously difficult to diagnose, nevermind understand, which is where a network-based approach comes in.

Researchers identify key protein associated with aging

Aging is a dramatic public health issue in the face of the current demographic changes: the proportion of 60 and over in the world's population will almost double by 2050. In this context, a new discovery has just broadened scientific knowledge.

New startup aims to prevent reperfusion-related organ damage after liver transplant

Roughly 65 years ago, the first human organ transplant was successfully performed. A decade later, heart and liver transplants became possible. Now, a startup founded by researchers from the Medical University of South Carolina and elsewhere hopes to bring about the next major breakthrough.
