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.

Learning about cellular proteins through “snapshots” of translation

Pep-tRNAs, nascent polypeptides inside the ribosome that are covalently connected to transfer RNA, are engaged in a variety of cell processes, including gene expression, according to advances in molecular biology.

Newly discovered enzyme tells specific molecules precisely how to arrange themselves

Just as a choreographer's notation tells a dancer to strike a particular pose, an enzyme newly discovered by Rice University scientists is able to tell specific molecules precisely how to arrange themselves, down to the angle of single hydrogen bonds.

Cryo-EM helps visualize the detailed structure of viral genome replication machinery

RNA viruses, such as the coronavirus that causes COVID-19, are in a life-and-death race the moment they infect a cell.

Accumulation of collagen at injured sites in the gut stimulates cellular reprogramming, study reveals

Most cells have a pretty normal life: they're born, they grow, they get old, and they die. But the Benjamin Buttons of the cellular world can go from old to young again in the right context.

Deep-learning model for zinc finger design allows reprogramming of human transcription factors

Researchers at the University of Toronto and New York University have developed a novel technology that can engineer proteins to target any stretch of DNA in the human genome, opening a door toward gene therapies for a broader range of health conditions.

The 12-hour cyclic gene activity abnormalities in schizophrenic brains

The first proof of 12-hour cycles of gene activity in the human brain is presented by researchers at the University of Pittsburgh School of Medicine in the United States.

Study sheds new light on a lifestyle switch that occurs in marine bacteria

Scientists have detailed a lifestyle switch that occurs in marine bacteria, where they change from coexisting with algae hosts in a mutually beneficial interaction to suddenly killing them.

New genetic condition that raises vulnerability to opportunistic infections

An international consortium co-led by Vanderbilt University Medical Center immunogeneticist Rubén Martínez-Barricarte, PhD, has discovered a new genetic disorder that causes immunodeficiency and profound susceptibility to opportunistic infections including life-threatening fungal pneumonia.

New toolkit enables researchers to map an individual’s RNA data to a much richer reference

Examining the gene expression of a person needs mapping the RNA landscape to a standard reference. This is done to gain an understanding of the degree to which genes are “turned on” and execute the functions in the body.

Interpretable framework to investigate the spatial organization of cells

In cells that are similar in form and function throughout tissues and organs, genes that are activated and expressed produce patterns. Identifying these patterns increases the understanding of cells, which could lead to the discovery of disease mechanisms.

Grasping how a biological pathway causes stem cells to regenerate or die

According to a recent study conducted by Cedars-Sinai and the University of California, San Francisco (UCSF), altering a cellular process can cause stem cells, which are the cells that give rise to all other types of body cells, to either die or regenerate.

Insights into the role of the germline in de novo mutation

The male reproductive system is a hotspot for the introduction of new genes. Perhaps that might assist in understanding why fathers tend to pass on more new mutations than mothers do. However, it does not explain why older fathers pass on more mutations than younger fathers.

Study suggests new strategies for controlling plant biochemistry

Plant biochemists at the U.S. Department of Energy's Brookhaven National Laboratory have discovered a new level of regulation in the biochemical "machinery" that plants use to convert organic carbon derived from photosynthesis into a range of ring-shaped aromatic molecules.

The continued functioning of circadian clock of cells even after starvation

According to a study that was just published in eLife, cells that have a functioning molecular clock are better able to adapt to changes in glucose supply and can recover from long-term starvation more quickly.

New solution to treat diseases caused by exaggerated inflammation

A recent study guided by the Instituto Gulbenkian de Ciência (IGC) shows how anticancer drugs reduce inflammation, establishing them as prospective sepsis treatments.

Analyzing the regulatory mechanisms of enzyme production in mold

Filamentous fungi have long been a close ally of sake brewers, but they may soon become associates of environmentalists as well. Scientists from Osaka Metropolitan University discovered the regulatory mechanisms of enzyme synthesis in a filamentous fungus, allowing for the effective degradation of plant biomass, an alternative energy resource to petroleum.

New open-access database provides a map of the proteome signature

The recently released cancer protein profile database, which was created using AI and machine learning, has helped with cancer prediction medicine. The new open-access Disease Blood Atlas, unveiled by KTH Royal Institute of Technology Professor Mathias Uhlén, gives the first-ever map of the proteome signature in cancer patients’ blood.
