Before a cell commits fully to the process of dividing itself into two new cells, it may ensure the appropriateness of its commitment by staying for many hours—sometimes more than a day—in a reversible intermediate state, according to a discovery by researchers at Weill Cornell Medicine. 

Interactions between two key structures within cells help establish the front-to-back “polarity” that is essential to cell migration, according to a new study by Weill Cornell Medicine researchers.

Cancers often release molecules into the bloodstream that pathologically alter the liver, shifting it to an inflammatory state, causing fat buildup and impairing its normal detoxifying functions.

Dr. Tobias Meyer, the Joseph C. Hinsey Professor in Cell and Developmental Biology at Weill Cornell Medicine, has been elected to the American Academy of Arts and Sciences.

A protein that prepares DNA for replication also prevents the replication process from running out of control, according to a new study by Weill Cornell Medicine researchers.

An enzyme that defends human cells against viruses can help drive cancer evolution towards greater malignancy by causing myriad mutations in cancer cells.

SARS-CoV-2 infections of women in late pregnancy frequently spread to their placentas and led to inflammation.

A protein called CDC7, long thought to play an essential role early in the cell division process, is in fact replaceable by another protein called CDK1, according to a study by investigators at Weill Cornell Medicine and the Dana-Farber Cancer Institute.

Researchers at Weill Cornell Medicine have developed a pre-clinical model of the leading cause of central vision loss in older individuals, called dry age-related macular degeneration (dry AMD), and used it to identify new treatment modalities and drug targets.

Dr. Bishoy Faltas works to develop more effective therapies for bladder cancer, a disease that’s notoriously hard to treat—and historically under-studied

A protein that breast, lung and other cancers use to promote their spread—or metastasis—to the brain, has been identified by a team led by Weill Cornell Medicine and New York-Presbyterian investigators. The protein, CEMIP, will now be a focus of efforts to predict, prevent and treat brain metastases, which are a frequent cause of cancer deaths.

Two molecular signaling pathways underlie the cardiac defects associated with one type of the inherited disorder Noonan syndrome (NS), researchers from Masonic Medical Research Institute, Beth Israel Deaconess Medical Center and Weill Cornell Medicine find in a new study.
