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.

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 ...

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 ...

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 ...

Genetic disorders — like cystic fibrosis and Huntington’s disease — are considered incurable, with gene mutations occurring in essentially every cell of the body. Gene mutations occur when one ...

Precision and timing of gene expression is essential for normal biological functions and, when disrupted, can lead to many ...

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 ...
