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.

KU Leuven researchers find that humans have lost ancient defense mechanism to combat viruses

Insects and plants have an important ancient defense mechanism that helps them to fight viruses. This is encoded in their DNA. Scientists have long assumed that vertebrates - including humans - also had this same mechanism. But researchers at KU Leuven, Belgium, have found that vertebrates lost this particular asset in the course of their evolution.

Penn study provides insight into how cells maintain identity during replication

Prior to cell division, chromosomes are seemingly a jumbled mess. During cell division, parent cell chromosomes and their duplicates sort themselves out by condensing, becoming thousands of times more compact than at any other time.

Mother’s breast milk may provide metabolic boost to premature babies

The breast milk of mothers with premature babies has different amounts of microRNA than that of mothers with babies born at term, which may help premature babies catch up in growth and development, according to researchers.

Probiotics may become new preventative or therapeutic strategy for IBD-related colon cancer

In an innovative approach to colorectal cancer (CRC) prevention and treatment, scientists are studying ways to replace missing metabolites in patients prone to gut inflammation and CRC.

Researchers identify connections between toxoplasmosis and several brain disorders

More than 2 billion people – nearly one out of every three humans on earth, including about 60 million people in the United States – have a lifelong infection with the brain-dwelling parasite Toxoplasma gondii.

Disrupting DNA loops could be potential strategy to reduce tumor proliferation

The discovery of a mechanism by which normal brain cells regulate the expression of the NFIA gene, which is important for both normal brain development and brain tumor growth, might one day help improve therapies to treat brain tumors. The study appears in the journal Nature Neuroscience.

Phthalate levels in expectant fathers influence sperm epigenetics, study suggests

Early results from a larger, ongoing study led by environmental health scientist Richard Pilsner at the University of Massachusetts Amherst suggest that phthalate levels in expectant fathers have an effect on couples' reproductive success via epigenetic modifications of sperm DNA.

Scientists uncover how gut bacteria and body clock work together to promote fat accumulation

UT Southwestern researchers have uncovered new clues about how gut bacteria and the body's circadian clock work together to promote body fat accumulation.

Researchers discover genetic calendar of brain aging

The program controls how and when brain genes are expressed at different times in a person's life to perform a range of functions, the study found.

Study provides new insights into biologic networks involved in IBD

Scientists at the Icahn School of Medicine at Mount Sinai, Sema4, and collaborating institutions today published results of an in-depth, multi-omics approach to characterizing the immune component of inflammatory bowel disease (IBD).

Regulatory T-cells can support fat depots in dealing with environmental challenges

Immunosuppressive regulatory T-cells play an important role in the functioning of adipose tissue. This is the discovery of scientists from the Helmholtz Diabetes Center at Helmholtz Zentrum München and the Technical University of Munich.

Study identifies genetic alterations with potential to promote aggressiveness of astrocytomas

Among the various types of cancerous brain tumors, 70% are astrocytomas. Fatal in as many as 90% of cases, astrocytomas originate in the largest and most numerous cells in the central nervous system, called astrocytes because of their star shape.

Color perception of medaka fish varies according to seasonal changes, research finds

In many areas, the environment fluctuates greatly depending on the season, and animals living in those areas must adapt to the changing environment.

A blood test that can diagnose PTSD may be on the horizon

Doctors may soon be able to diagnose post-traumatic stress disorder (PTSD) using a simple blood test, after scientists identified genetic changes in soldiers who experienced trauma after serving time in Afghanistan.

Even small tumors can be aggressive in early stage breast cancer patients, study shows

Even small tumors can be aggressive, according to a study in patients with early stage breast cancer that will be presented at the ESMO 2017 Congress in Madrid.

Biologists unlock key elements behind animal kinship attachments

A baby lamb is separated from its family. Somehow, in vast herds of sheep that look virtually identical, the lost youngling locates its kin. Salmon swim out to the vast expanses of the sea and migrate back home to their precise spawning grounds with bewildering accuracy.

Researchers explore causal link between perirhinal neurons and mnemonic judgment of objects

Cognitive neuroscience research on non-human primates demonstrated that judgments of whether humans have previously seen or not seen an object are causally determined by neuronal signals generated in the temporal cortex of the brain. The findings are published in Science (August 2017).

St. Jude creates world’s largest collection of pediatric solid tumor samples

In an effort to improve outcomes for patients with some of the deadliest childhood cancers, St. Jude Children's Research Hospital scientists have created the world's largest collection of pediatric solid tumor samples, drug-sensitivity data and related information and have made the resource available at no charge to the global scientific community.

New biomedical tool using nanoparticles could improve therapies for many diseases

A new biomedical tool using nanoparticles that deliver transient gene changes to targeted cells could make therapies for a variety of diseases - including cancer, diabetes and HIV - faster and cheaper to develop, and more customizable.

Defect in DNA repair machinery causes underdevelopment of neural network

DNA is the computer code that programs every event in the body. Despite the importance of DNA fidelity, as the body develops, cells grow and replicate, DNA is constantly turned over. This repeated process can compromise the DNA, which is why the body has many DNA repair machineries.
