Pioneering Research Illuminates Breast Cancer, Like You’ve Never Seen it Before

University of Virginia Health System

University of Virginia researchers have developed a revolutionary three-dimensional model that allows them to visualize how breast tissue grows in its earliest stages, giving them the closest look ever at the very beginnings of breast cancer. The new model represents a major scientific milestone – it’s the first time scientists have been able to successfully and accurately replicate the early growth of human breast tissue outside of the body.

Scientists Reveal New Survival Mechanism for Neurons

Johns Hopkins Medicine

Nerve cells that regulate everything from heart muscle to salivary glands send out projections known as axons to their targets. By way of these axonal processes, neurons control target function and receive molecular signals from targets that return to the cell body to support cell survival. Now, Johns Hopkins researchers have revealed a molecular mechanism that allows a signal from the target to return to the cell body and fulfill its neuron-sustaining mission.

In Cell Culture, Like Real Estate, the Neighborhood Matters

University of Wisconsin-Madison

Ever since scientists first began growing human cells in lab dishes in 1952, they have focused on improving the chemical soup that feeds the cells and helps regulate their growth. But surfaces also matter, says Laura Kiessling, a professor of chemistry at the University of Wisconsin-Madison.

Going with the Flow

Stowers Institute for Medical Research

Most cells rely on structural tethers to position chromosomes in preparation for cell division. Not so oocytes. Instead, a powerful intracellular stream pushes chromosomes far-off the center in preparation for the highly asymmetric cell division that completes oocyte maturation upon fertilization of the egg, report researchers at the Stowers Institute for Medical Research.

Rare Cell Is Asset and Liability in Fighting Infection

Washington University in St. Louis

The same trait that makes a rare immune cell invaluable in fighting some infections also can be exploited by other diseases to cause harm, two new studies show.

Researchers Identify New Target for Treatment of Type 2 Diabetes and Prediabetes

Joslin Diabetes Center

Researchers at the Joslin Diabetes Center have shown that an enzyme found in the mitochondria of cells is decreased in the skeletal muscle of those with type 2 diabetes, a finding that could lead to the development of drugs to boost the activity of this enzyme in an effort to fight the disease.

Cancer Stem Cells Made, Not Born

Whitehead Institute for Biomedical Research

New findings by scientists at the Broad Institute of MIT and Harvard and Whitehead Institute point to a decentralized society in tumors, with cancer cells able to interconvert between different types. These results have potential implications for the treatment of tumors, in particular, that attacking cancer stem cells alone may not be enough to fight cancer.
