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.

Mother's diet during pregnancy can impact lung-specific genes of her offspring

Children born to women pregnant during the Dutch famine were more likely to have a constellation of health problems including cardiovascular disease and asthma, but the exact mechanisms that cause this epigenetic inheritance have not been fully explored.

Cholesterol lowering drug can also help treat cancer-associated cachexia

Brazilian researchers have discovered that a drug regularly prescribed to control cholesterol can also be used to treat cachexia, or wasting syndrome, a condition characterized by rapid weight loss and muscle atrophy associated with extreme physical weakness.

Researchers identify origin of chronic pain in humans

A new study by researchers at The University of Texas at Dallas, UT MD Anderson Cancer Center, UT Health Science Center at Houston and Baylor College of Medicine has produced evidence of the source of chronic pain in humans, revealing several new targets for pain treatment.

A novel approach for treating inflammatory arthritis

Researchers at the University of Minnesota, in collaboration with researchers at Medtronic, have shown that noninvasive daily ultrasound stimulation of the spleen in mice with inflammatory arthritis resulted in significantly less joint swelling compared to arthritic mice that were not treated.

Machine learning approach sheds light on the biology of liver and kidneys after toxin exposure

Exposure to potentially harmful chemicals is a reality of life. Our ancestors, faced with naturally occurring toxins, evolved mechanisms to detoxify and expel damaging substances.

Free fatty acids in the blood linked with elevated risk of breast cancer in obese women

Scientists at the University of Illinois have found that free fatty acids in the blood appear to boost proliferation and growth of breast cancer cells. The finding could help explain obese women's elevated risk of developing breast cancer after menopause.

Study: Early-life exposure to microbiota inhibits colon cancer in adulthood

Exposure to microbiota, or microorganisms such as bacteria, in the early stages of life plays a crucial role in establishing optimal conditions in the intestine that inhibit the development of colon cancer in adulthood, according to a study led by Georgia State University.

Columbia researchers explore molecular mechanisms of treatment-resistant depression

Major depressive disorder is a debilitating illness that affects more than 350 million people around the world.

Exosomes are key to SOS signal that the heart muscle sends out after heart attack, study reveals

Human cells shed exosomes. These tiny extracellular, membrane-bound vesicles can carry cargo for cell-to-cell communication, ferrying diverse loads of proteins, lipids or nucleic acids.

New data describes way to reliably quantify a person's 'immune age'

New data, published in Nature Medicine, from scientists at the Technion, Stanford and CytoReason describes for the first time ever a way to reliably quantify a person's "immune age".

Researchers unravel how the immune system responds to diffuse cutaneous leishmanisis

In diffuse cutaneous leishmanisis, a rare form of leishmaniasis, parasites grow uncontrolled in skin lesions across the body.

DNA sequencing method could aid development of anticancer drugs

DNA is small. Really, really, small. So, when researchers want to study the structure of a single-stranded DNA, they can't just pull out their microscopes: they have to get creative.

Mother's treatment for infection during pregnancy increases child's risk for autism and depression

Risks for autism and depression are higher if one's mother was in hospital with an infection during pregnancy. This is shown by a major Swedish observational study of nearly 1.8 million children.

Genetic manipulation can double life expectancy and increase health of offspring

By manipulating the genes that make humans age, researchers have discovered that lifespans can be doubled with a better quality of life for offspring.

New mathematical method to map cell regulatory networks

Faster results. Lower costs. Fewer cells. A new mathematical method developed by researchers at Cincinnati Children's and New York University may soon make it much easier to conduct more of the complex data analysis needed to drive advances in the exploding field of personalized medicine.

Liver tissue model can help investigate the effects of RNA interference

Novel therapies based on a process known as RNA interference hold great promise for treating a variety of diseases by blocking specific genes in a patient's cells. Many of the earliest RNAi treatments have focused on diseases of the liver, because RNA-carrying particles tend to accumulate in that organ.

Researchers identify common genetic signature among three rare skin diseases

A group of researchers lead by a lecturer from the Universidad Carlos III de Madrid, Marcela del Río, from the CIEMAT, the Rare Diseases Networking Biomedical Research Centre and Fundación Jiménez Díaz has identified a common genetic signature among three rare skin diseases or genodermatoses: recessive dystrophic epidermolysis bullosa, Kindler syndrome and xeroderma pigmentosum.
