Looking Beyond the Gene: An Introduction

September 30, 2019

Whitehead Institute researchers are uncovering new ways that genes are regulated that upend existing paradigms of gene expression and provide important insights into health and disease. This collection of stories and multimedia explores that research.

Signaling factor seeking gene

September 25, 2019

Whitehead Institute researchers have discovered that particular signaling pathways, which transmit environmental cues and effect changes in gene expression, rely on phase-separated condensates to find, occupy, and activate the right genes in each cell type

Activating a new understanding of gene regulation

November 15, 2018

A previously mysterious part of transcription factors, the activation domain, plays a key role in forming phase separated "droplets" that concentrate proteins required for transcription near genes

Transcriptional droplets provide evidence for new model of gene control

June 21, 2018

Whitehead Institute scientists have found evidence that the apparatus that transcribes DNA into RNA is concentrated into specialized droplets, or “condensates”, at genes that control cell identity.

New study prompts rethinking transcription factor’s role in control of gene expression

Like proteins, genomes must fold appropriately to function properly; some transcription factors provide the structural support

There goes the neighborhood: Changes in chromosome structure activate cancer-causing genes

March 3, 2016

In a finding with enormous implications for cancer diagnostics and therapeutics, Whitehead Institute scientists have discovered that breaches in looping chromosomal structures known as “insulated neighborhoods” can activate oncogenes capable of fueling aggressive tumor growth.

3D map of human genome reveals relationship between mutations and disease development

December 10, 2015

Whitehead Institute researchers have created a map of the DNA loops that comprise the three dimensional (3D) structure of the human genome and contribute to gene regulation in human embryonic stem cells. The location of genes and regulatory elements within this chromosomal framework will help scientists better navigate their genomic research, establishing relationships between mutations and disease development.

Special chromosomal structures control key genes

October 7, 2014

Scientists have long theorized that the way in which the roughly three meters of DNA in a human cell is packaged to fit within a nuclear space just six microns wide, affects gene expression. Now, Whitehead Institute researchers present the first evidence that DNA structure does indeed have such effects—in this case finding a link between chromosome structure and the expression and repression of key genes.

Super-enhancers seen as ‘Rosetta Stone’ for dialog between genes and disease

October 10, 2013

Having recently discovered a set of powerful gene regulators that control cell identity in a few mouse and human cell types, Whitehead Institute scientists are now showing that these regulators—which they named “super-enhancers”—act across a vast array of human cell types and are enriched in mutated regions of the genome that are closely associated with a broad spectrum of diseases.
