Coordinating the Development of Heart Muscle and Vasculature

During development, regional dips in oxygen levels serve as a signal that triggers the coordinated growth of heart muscle and coronary vessels, according to a study led by researchers at Weill Cornell Medicine. The findings, published online in the Proceedings of the National Academy of Sciences, could point toward innovative approaches for treating cardiovascular conditions that lead to heart failure.

“The signaling pathways that direct the development of this remarkable organ are also affected in pathological conditions,” said Dr. Michael Harrison, assistant professor of cell and developmental biology and a member of the Cardiovascular Research Institute of Weill Cornell Medicine. “Interventions that target these signals or the cells that produce them could potentially change the trajectory of disease or slow its progression.”

Looking for the Leader

As a postdoctoral fellow, Dr. Harrison explored how coronary vessels influence cardiac regeneration in zebrafish, a useful model for studying heart development and repair. “Looking through the literature, I realized that we knew very little about how coronary vessels develop in the first place,” he said.

A Promising Solution to a Cancer Drug Resistance Problem

A protein that can dial down oxidative stress in cells helps some cancers resist treatment with a widely used class of drugs called BTK inhibitors, according to a study led by investigators at Weill Cornell Medicine. The discovery points to a possible solution to the problem of BTK inhibitor treatment resistance.

BTK inhibitors reduce the activity of the enzyme BTK (Bruton’s Tyrosine Kinase), which has a central role in immune cells called B cells. Inhibiting BTK chokes off the ability of B cells to proliferate, which has benefits against some blood cancers including several types of lymphoma. Unfortunately, these malignancies often lose their sensitivity to BTK inhibitors after a year or two of treatment. In the study, published July 2 in Nature Communications, the researchers discovered that in mantle cell lymphoma, a common mechanism of resistance to BTK inhibitors involves aberrant activity of a protein called BRG1. They found that BRG1 protects cells from BTK-inhibitor treatment by suppressing a cell-killing process called ferroptosis, an iron-dependent form of cell death that BTK inhibitors otherwise induce.
