How Is Gene Expression Regulated? The amounts and types of mRNA molecules in a cell reflect the function of that cell. In fact, thousands of transcripts are produced every second in every cell.

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 ...

But a study published November 9 in ACS Central Science finds that microRNAs (miRNAs) can also amplify gene expression. “It changes the landscape of microRNA,” Lara Mahal, a chemist at the University ...

In previous work, the team has shown that some HARs alter gene expression in human-specific ways compared with our closest primate relatives. The latest study greatly expands the understanding of ...

A new study led by Prof. Yosef Buganim from the ... are proteins that bind to specific DNA sequences to control gene expression, guiding cells to become specific types—such as skin, muscle ...

A multi-institutional team of investigators have developed a catalog of transcription factor binding sites that regulate gene expression across the genome, according to a recent study published in ...
