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.

Mouse model closely replicates human NAFLD

Human non-alcoholic fatty liver disease (NAFLD) is a little-understood condition that significantly increases the risk of inflammation, fibrosis and liver cancer and ultimately requires liver transplant.

Researchers discover molecular signatures of aging process in mice

Researchers have identified molecular signatures of the aging process in mice, publishing their results today in the open-access eLife journal.

Aged bone marrow niche restrains function of rejuvenated HSCs, shows study

When leukemia strikes an older person, it is in part due to the aging of his or her hematopoietic stem cells (HSCs).

Biology of single-celled organisms reveals potential treatment target for COPD

In a series of experiments that began with amoebas -- single-celled organisms that extend podlike appendages to move around -- Johns Hopkins Medicine scientists say they have identified a genetic pathway that could be activated to help sweep out mucus from the lungs of people with chronic obstructive pulmonary disease a widespread lung ailment.

DNA supercoiling is involved in the control of gene expression

The (when stretched) two-meter-long DNA molecule in each human cell is continuously being unpacked and packed again to enable the expression of genetic information.

New approach to scale up genome editing in tiny worms

Understanding the effects of specific mutations in gene regulatory regions - the sections of DNA and RNA that turn genes on and off - is important to unraveling how the genome works, as well as normal development and disease.

COVID19's cytokine storm ushers in a local complement storm in the lungs

A new study published in the journal Science Immunology analyzed lung epithelial cells from patients infected with COVID-19 and found the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) induces the complement system as a dangerous weapon for viral infection.

Study shows how nitrate controls gene expression in legumes

Plants in the bean family (legumes) form nodules on their roots to take up nitrogen. Legumes will stop nodule production when nitrogen is plentiful, but precisely how nitrate presence controls nodule formation in these plants has been a mystery.

Obesity reduces mitochondrial gene expression in fat tissue, finds study

A twin study recently completed at the University of Helsinki indicates that the machinery responsible for energy handling in fat tissue is working poorly in obesity.

Study uncovers molecular reason why fecal transplants effectively treat C. difficile infections

Experts have uncovered a new molecular reason why faecal transplants are highly effective in treating infections such as C. difficile (a nasty bacteria that can infect the bowel), which could lead to more targeted treatments for this and other similar diseases.

Novel technique could speed up recovery from bone replacements

An international research team led by Monash University has uncovered a new technique that could speed up recovery from bone replacements by altering the shape and nucleus of individual stem cells.

Antipsychotics could have a protective impact against SARS-CoV-2

Two studies led by the Mental Health Unit of the Virgen del Rocio University Hospital and involving researchers from the US conclude that antipsychotic drugs could have a protective effect against SARS-CoV-2. For this reason, patients treated with these drugs have a lower risk of becoming infected or suffer a milder form of the disease if they do become infected.

Study shows Urolithin A as a potent enhancer of muscle function in mice with muscular dystrophy

Progression of Duchenne Muscle Dystrophy (DMD) can be delayed in mice by supplementing their diets with Urolithin A, according to new results reported today.

Study shows how melanoma cells evade detection and destruction by immune cells

A dysfunctional immune system significantly contributes to the development of cancer. Several therapeutic strategies to activate the immune system to target cancer cells have been approved to treat different types of cancer, including melanoma.

Powerful algorithms can 'predict' the biological language of cancer and Alzheimer's

Powerful algorithms used by Netflix, Amazon and Facebook can 'predict' the biological language of cancer and neurodegenerative diseases like Alzheimer's, scientists have found.

Microrna-29 molecule controls brain maturation in mammals

A team led by scientists at the UNC School of Medicine identified a molecule called microRNA-29 as a powerful controller of brain maturation in mammals. Deleting microRNA-29 in mice caused problems very similar to those seen in autism, epilepsy, and other neurodevelopmental conditions.

Urolithin A shows promise to slow progression of Duchenne Muscle Dystrophy

Progression of Duchenne Muscle Dystrophy (DMD) can be delayed in mice by supplementing their diets with Urolithin A, according to new results reported today.

Researchers discover two new ways to treat small cell lung tumors

Using samples of small cell lung tumors, a research team led by biologist Dr Silvia von Karstedt has discovered two new ways to induce tumor cell death. One of two subsets of tumor cells can be targeted by activating ferroptosis: iron-dependent cell death caused by oxidative stress

New biomarker of glucocorticoid action could help clinicians to tailor treatments

Researchers have uncovered pathways involved in the body's response to glucocorticoid treatments and identified a novel biomarker that could be used to monitor how these drugs work in patients, according to a clinical study published today in eLife.
