From the TATA box to alternative splicing and noncoding RNAs, scientists are uncovering the intricate choreography that controls gene expression. These molecular mechanisms determine when, where, and ...

When a gene is turned on in a cell, it creates a ripple effect along the DNA strand, changing the physical structure of the ...

In back-to-back studies published in Nature, researchers from Purdue University and Columbia University report a naturally evolved gene-editing system that can activate genes, offering an advantage ...

Our brain is arguably the organ that most distinguishes humans from other primates. Its exceptional size, complexity and capabilities far exceed those of any other species on Earth. Yet humans share ...

A new study finds the proteins responsible for controlling which genes are expressed in a genome do more than simply turn a gene on or off. Essentially, each type of protein that interacts with a gene ...

It could be simply to control gene expression." The study, "Global impact of unproductive splicing on human gene expression levels and traits," was supported by funding from the National Institutes of ...

Scientists identified 473 human genes that act as genetic “on/off switches,” shaping disease risk through tissue-specific or universal patterns regulated by DNA changes and hormones. Study: ...

Chronic alcohol consumption profoundly alters gene expression in key brain regions involved in reward, impulse control, and decision-making, according to a study led by researchers at the Institute ...

The natural RNAi mechanism can be directed by either short interfering RNA (siRNA) or microRNA (miRNA). 1 There are four key steps in the RNAi pathway. When miRNA acts as the guide for RNAi, only a ...

Genetics is the study of genes and how they influence characteristics and health. Through a variety of technological methods, environmental factors, and lifestyle choices, it is possible to alter some ...
