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.

New model helps assess the effect of epigenetic changes on gene expression

Researchers have developed a mathematical model to quantitatively assess the impacts of particular epigenetic changes on the transcription rates.

Obesity allows cancer cells to outcompete tumor-killing immune cells, study finds

Obesity has been linked to increased risk for over a dozen different types of cancer, as well as worse prognosis and survival.

Researchers discover genetic factors underlying diabetic retinopathy

In a quest to find the genetic factors that are fundamental to diabetic retinopathy, scientists from the University of Illinois Chicago (UIC) have also discovered a new method that can be employed as a template to investigate other types of diseases.

Gene therapy and medication can provide certain beneficial effects of physical exercise

Jose Bianco Moreira from NTNU is now convinced that gene therapy can be used to achieve the positive health benefits of physical exercise.

Scientists propose a simple model for gene regulation in higher organisms

Although the DNA and its double-helix are some of the most familiar molecules of our time, our knowledge of how cells control what genes they want to express still is rather limited. In order to create, for example, an enzyme, the information that's inscribed in our DNA about this enzyme needs to be transcribed and translated.

Drug meant for bacterial infections can combat weight gain

A drug originally developed to treat bacterial infections has proved capable of boosting the metabolism and attenuating the weight gain induced by a fatty diet in tests with mice. The study was conducted at the University of Campinas (UNICAMP) with FAPESP's support, and the findings have just been published in the journal Science Advances.

Researchers identify molecular mechanisms that reverse aging

Cellular reprogramming can reverse the aging that leads to a decline in the activities and functions of mesenchymal stem/stromal cells (MSCs).

New study refutes a major cellular process in bacteria

Despite explanations in textbooks, a new study has discovered and elucidated a cellular process that has continued to remain a mystery for researchers.

Using 3D mapping techniques to unravel mystery of blood stem cells

Princess Margaret scientists have revealed how stem cells are able to generate new blood cells throughout our life by looking at vast, uncharted regions of our genetic material that hold important clues to subtle biological changes in these cells.

Adipose tissue plays key role in the aggravation of COVID-19

There is growing evidence that adipose tissue plays a key role in the aggravation of COVID-19. One of the theories under investigation is that fat cells (adipocytes) act as a reservoir for SARS-CoV-2 and increase viral load in obese or overweight individuals.

Scientists discover new functions of key cellular machine involved in human cancers

Utah scientists have discovered new functions of a key cellular machine that regulates gene packaging and is mutated in 20% of human cancers. The study was published in print today in the journal Molecular Cell.

Study outlines transient prospective stages in development of neural crest cells

Last year, researchers at the University of California, Riverside, identified the early origins of neural crest cells -- embryonic cells in vertebrates that travel throughout the body and generate many cell types -- in chick embryos.

Polβ enzyme prevents breakdown of DNA in the hippocampus region

It's a fact of life that things break down. And when they do, whether it's your car, the roof, or a blocked artery, there are people who we can call to help with the repairs.

Placental gene expression related to preeclampsia may be affected by vitamin D status

According to the World Health Organization, preeclampsia affects between 2% to 8% of pregnancies. It can cause serious, sometimes fatal, complications in the mother and child.

Study shows how coronavirus block cells’ ability to produce protective proteins

One of the novel coronavirus' most insidious tricks is that it can block the ability of cells to produce protective proteins without hindering its own ability to replicate.

Researchers create “developmental atlas” to classify the neurons of fruit flies

Using machine learning and gene sequencing, scientists from New York University have designed a “developmental atlas” of gene expression in neurons to classify over 250,000 neurons in the brains of fruit flies.

Teratomas could provide a new glance at human development

Finding just the right model to study human development--from the early embryonic stage onward--has been a challenge for scientists over the last decade.

Root microbiota may play a key role in optimal plant growth

Researchers from the Max Planck Institute for Plant Breeding Research have found that, faced with limiting iron, plants direct their microbiota to mobilize this essential nutrient for optimal growth.

Study reveals proteins that enable SINEUPs to increase protein production

Scientists from an international group led by the RIKEN Center for Integrative Medical Sciences and Yokohama City University have discovered that a pair of proteins play a key role in allowing an important type of functional non-coding RNA, known as SINEUPs, to act to promote their target messenger RNA.
