Gene expression and pathway analysis constitute a critical nexus in modern molecular biology, facilitating the exploration of how genes collectively influence cellular functions and disease processes.

The correct functioning of cells relies heavily on the ability to finely control gene expression, a complex process by which the information contained in DNA is copied into RNA to eventually give rise ...

Epigenetics is the study of various heritable alterations that control gene expression without changing the DNA sequence. 1 The name epigenetics comes from the Greek prefix “epi”, which means on top ...

New research suggests that alternative splicing may have an even greater influence on biology than just by creating new protein isoforms. The study shows that the biggest impact of alternative ...

What if a cup of coffee could help treat cancer? Researchers at the Texas A&M Health Institute of Biosciences and Technology ...

What do your genes have to do with growing old? Quite a lot. But is it due to the actual DNA, or the way those genes are expressed? KPBS sci-tech reporter Thomas Fudge has more on new research that ...

All the cells in an organism have the exact same genetic sequence. What differs across cell types is their epigenetics—meticulously placed chemical tags that influence which genes are expressed in ...

While the process via which different types of neurons are produced, also known as neurogenesis, has been the focus of numerous neuroscience studies, its genetic and biological underpinnings in humans ...

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 ...

Researchers are adding new evidence to the emerging concept that 'silent' or synonymous mutations may have crucial consequences. Their study showed how a synonymous mutation in one gene can ...
