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.

Physical activity may help fight depression in seniors

The benefits of exercise are widely known but kinesiologists at McMaster University have for the first time found that physical activity may help fight depression in seniors by stimulating muscle-generated mood boosters.

Study shows precision medicines could aid more breast cancer patients via RNA-targeting

When women or men receive the worrisome diagnosis of breast cancer, that news comes with an important piece of information, namely, whether their cancer is HER2-positive or HER2-negative.

Insufficient sleep mirrored by DNA from blood leukocytes

An insufficient amount of sleep and qualitatively poor sleep are common among the general population. Prior studies have indicated that prolonged insufficient sleep and poor sleep quality are associated with a heightened risk of cardiovascular diseases, dementia and psychiatric disorders, particularly depression, yet the molecular mechanisms underlying this connection are not well known.

Detecting and mapping of chemicals inside a biological cell

How are chemicals distributed in a cell? Chinese scientists have developed a combined mass spectrometry and biological imaging device that enables direct, label-free detection, and high-resolution mapping of chemicals inside a biological cell.

New acute porphyria treatment shows promising results in clinical study

Acute porphyria is a group of uncommon diseases that can cause severe, potentially life-threatening attacks of abdominal pain, nausea, vomiting and paralysis. Liver transplantation is currently the only effective treatment available for the most seriously afflicted patients.

New study points to potential cure for addiction

The Akay Lab biomedical research team at the University of Houston is reporting in the journal Nature Scientific Reports that a possible cure for addiction may be found by following the pathways of significantly altered dopamine neurons in newborns who were chronically exposed to nicotine in utero.

Chloroplast retrograde signaling attenuates elongation response to shade in plants

Plants need sunlight to feed and grow. Without light, the photosynthesis, the reaction by which the plant chloroplasts convert atmospheric CO2 and water into sugars and oxygen, cannot take place.

Oxford Nanopore launches new cDNA Kits for its sequencing technology

Oxford Nanopore has launched new '109' cDNA Kits for its real-time, scalable sequencing technology. The new kits provide high throughput whilst generating complete sequences of full-length cDNA strands, with a low input option of just 1ng PolyA+ RNA.

Researchers link protein clusterin to many facets of cardiometabolic syndrome risk

During a study spanning nearly a decade, researchers at The Ohio State University College of Medicine, Houston Methodist Research Institute and Houston Methodist Cancer Center have linked the protein clusterin - for the first time -- to many different facets of cardiometabolic syndrome risk through its actions in the liver.

Warmer water and chemical exposure influence gene expression in North American fish

Warmer water temperatures, combined with low-level exposure to chemicals already known to be harmful to aquatic life, influence the expression of genes in the offspring of an abundant North American fish species - and threaten organisms whose sex determination is sensitive to water temperature.

Fasting may boost human metabolic activity, research suggests

Fasting may help people lose weight, but new research suggests going without food may also boost human metabolic activity, generate antioxidants, and help reverse some effects of aging.

Exercise-induced muscle changes could help boost mood in older adults, study suggests

New research suggests that exercise-induced muscle changes could help boost mood in older adults. The study is published ahead of print in the American Journal of Physiology--Cell Physiology.

RNA-binding protein needed for development of pathological hypertrophy

In response to conditions such as high blood pressure and reduced blood flow to cardiac muscle, the adult heart can drastically enlarge, a process called pathological hypertrophy that preserves cardiac function in the short term but predisposes patients to intractable heart failure and sudden cardiac death if left untreated.

New autism mouse model shows how epigenetic regulation impacts downstream gene

The causes of autism spectrum disorder are diverse and to some extent, unknown. But without doubt, they are complex, layered and deeply nuanced.

Researchers discover how transcription factors find specific loci within DNA

Bioengineering experts have discovered that transcription factors which bind non-specifically to mitotic chromosomes are more efficient at finding their binding site within DNA during interphase.
