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.

Short-term exposure to low levels of air pollution can affect gene expression

New data from a landmark study by Monash University researchers raises concerns that even short-term exposure to low level air pollution can affect gene expression, leaving us at risk of diseases such as cancer, cardiovascular and respiratory diseases.

Study sheds light on the reproductive role of 'dark matter' DNA

Researchers from the Okinawa Institute of Science and Technology Graduate University have shed light on the reproductive role of 'dark matter' DNA - non-coding DNA sequences that previously seemed to have no function.

Protein glycosylation plays a major role in DNA methylation

An underlying principle in molecular biology is that “DNA makes RNA makes protein.” The process of gene expression is firmly controlled in various ways.

Intron detention is integral to post-transcriptional regulation mechanism

Muscle stem cells are the reserve stem cells found in skeletal muscles. They play a crucial role in muscle repair following damage.

Researchers develop intracellular biopsy to isolate targeted miRNAs from living cells

MicroRNAs, are attracting interest relating to human diseases because variations in the expression of miRNAs are often associated with abnormal functions.

KAUST scientists reveal the genetic metronome within malaria parasites

The parasites responsible for malaria seem to march to their own beat.The mystery behind the molecular basis of how these parasites synch their rhythm in replication to the host's clock-driven rhythms has been solved.

Study shows how a fat cell's immune response exacerbates obesity

When obesity occurs, a person's own fat cells can set off a complex inflammatory chain reaction that can further disrupt metabolism and weaken immune response--potentially placing people at higher risk of poor outcomes from a variety of diseases and infections, including COVID-19.

Single-cell-resolution technologies help map brain regions in humans and primates

Using the single-cell-resolution transcriptomics technologies, researchers have performed a large-scale analysis of gene expression in 33 different brain regions of chimpanzees, bonobos, macaques, and humans, and successfully generated a map of the various brain regions with their particular cell structures.

New image of LSD1 enzyme in action could provide insight into gene regulation

New images of an enzyme in action as it interacts with the chromosome could provide important insight into how cells--including cancer cells--regulate their genes.

Researchers discover how a microRNA protects vascular integrity

Ludwig-Maximilian-Universitaet in Munich researchers have discovered a hitherto unknown molecular function of a specific microRNA that preserves integrity of the endothelium and reduces the risk of atherosclerosis.

Salk researchers discover how cells remember their identity

Cancer is often the result of DNA mutations or problems with how cells divide, which can lead to cells "forgetting" what type of cell they are or how to function properly.

Study uncovers why developing nerve cells take a wrong turn

A group of scientists from CECAD, the Cluster of Excellence 'Cellular Stress Responses in Aging-Associated Diseases,' have found a mechanism by which neurodevelopmental diseases concerning neurons can be explained: The loss of a certain enzyme, UBE2K, impeded the differentiation of stem cells by silencing the expression of genes important for neuronal differentiation and, therefore, the development and generation of neurons.

Dramatic increase in immune cells in mouse lungs after birth may help protect against infections

An explosion in the number and types of immune cells in the lungs of newborn mice likely helps them adapt to breathing and protects them from infection, says a new study published today in eLife.
