Leveraging a novel system designed to examine the double-strand DNA breaks that occur as a consequence of gene amplification during DNA replication, Whitehead Institute scientists are bringing new clarity to the causes of such genomic damage. Moreover, because errors arising during DNA replication and gene amplification result in chromosomal abnormalities often found in malignant cells, these new findings may bolster our understandings of certain drivers of cancer progression.

Using a mouse model, the lab of Whitehead Institute Founding Member Harvey Lodish, has now determined that combining the cholesterol-lowering drug fenofibrate with glucocorticoids could allow for dramatically lower steroid doses in the treatment of Diamond Blackfan anemia and other erythropoietin-resistant anemias.

Scientists have applied a new method of analyzing cell states to identify a gene required for breast stem cells to differentiate. This gene, RUNX1, is deregulated or mutated in some leukemias and breast cancers. The novel approach, known as PEACS, could also be used to screen for drugs that activate or inhibit the expression regulators of stem cell differentiation.

The UK’s Royal Society today announced that it has elected Whitehead Institute’s Susan Lindquist as a Foreign Member.

The prize honors Jaenisch’s groundbreaking body of work in epigenetics, the development of transgenic animals, and the generation and use of induced pluripotent stem (iPS) cells.
Imaging immunity: Noninvasive imaging of immune system detects tumors, could monitor therapeutic response
April 20, 2015
A novel approach that allows real-time imaging of the immune system’s response to the presence of tumors—without the need for blood draws or invasive biopsies—offers a potential breakthrough both in diagnostics and in the ability to monitor efficacy of cancer therapies.

Whitehead Institute Member Jing-Ke Weng is among 15 young scientists nationwide to be named a 2015 Searle Scholar.

Biologists at Whitehead Institute and MIT have discovered a vulnerability of brain cancer cells that could be exploited to develop more-effective drugs against brain tumors.

Candida albicans is a human pathogen that causes potentially lethal infections in immunocompromised individuals. Efforts to overcome Candida’s innate resistance to many drugs have been thwarted by an absence of tools enabling genetic modifications. Now, using a modified CRISPR-Cas system, Whitehead Institute researchers can edit the fungus’s genome systematically—an approach that could help scientists understand Candida’s unique biology and identify potential drug targets.

A team of Whitehead Institute scientists has discovered that during division, stem cells distinguish between old and young mitochondria and allocate them disproportionately between daughter cells.

Although the genome editing system known as CRISPR/Cas has revolutionized genetic research in cell lines, its overall efficiency has been relatively poor when used to generate genetically altered animals for disease modeling. Now Whitehead Institute scientists have altered the approach in a manner that could accelerate the production of mice carrying precise mutations of multiple genes.

Scientists in the lab of Whitehead Institute Member David Sabatini have for the first time identified a protein that appears to be a nutrient sensor for the key growth-regulating mTORC1 metabolic pathway.
