Much of the phenotypic variation that is observed within and between species is the result of differences in gene regulation: specifically when, where and how much the genes are expressed. Given the ...

Gene regulation is the process by which cells control the expression of their genes, determining when, where, and to what extent each gene is expressed. It is a fundamental mechanism that allows cells ...

Scientists mapped hidden DNA switches in brain support cells to understand how gene control may influence Alzheimer’s disease ...

Northwestern Medicine scientists have discovered how molecular "traffic controllers" in cells influence aging and cellular ...

A research team has identified the core gene expression networks regulated by key proteins that fundamentally drive phenomena such as cancer development, metastasis, tissue differentiation from stem ...

In biology classrooms, we often learn that genes are transcribed into mRNA, which is then translated into proteins—a tidy, linear process. But gene expression in living cells is far more intricate, ...

The human genome contains approximately 1,600 types of transcription factors responsible for regulating gene activity across ...

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 ...

Scientists successfully extract RNA from a 130-year-old Tasmanian tiger, thylacine, revealing how its genes functioned before its extinction.

Plant bioengineering—in which plant genes are modified to include desirable characteristics—is the key to solutions for problems concerning crop resilience and food security. Elements like gene ...
