Beyond the Lab Bench: A Look at the Traditions That Make Whitehead Institute Unique

April 30, 2020

On the 4th floor of Whitehead Institute, scientists have found a unique way to cope with the rainy period of early spring — a competition where teams of eight try to exercise the most minutes. And it has helped a sizable part of the Whitehead community cope with social distancing during the COVID-19 pandemic.

The surprising individuality of microRNAs

December 5, 2019

Whitehead Institute researchers advance the predictive model for the influence of microRNAs on gene expression in a cell. Their findings illustrate that high-, medium-, and low-affinity microRNA target sites unexpectedly vary between different microRNAs, and that in some cases they include imperfectly matched sequences.

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.

Pairing mismatch helps impaired fish RNA cleavage proceed swimmingly

December 21, 2017

Researchers at Whitehead Institute have uncovered how small changes in the fish Argonaute (Ago) protein, an RNA slicing protein, that happened in its lineage an estimated 300 million years ago greatly diminished the efficiency of RNAi in these animals, while another ancestral feature, in a critical pre-microRNA, was retained that enabled the microRNA to still be produced despite the fish’s impaired Ago protein.

A protein-production tale of the tape: separating poly(A)-tail length from translational efficiency

January 29, 2014

Whitehead Institute researchers have determined that poly(A) tails on messenger RNAs (mRNAs) shift their role in the regulation of protein production during early embryogenesis. This finding about the regulation of mRNA translation also provides insight into how microRNAs control protein production.
