Iron is an essential micronutrient, but excess iron can damage cells and increase cancer risk. While many cells die from iron-induced oxidative stress, a subset survives and may become cancerous.

For decades, biologists assumed a cell's energy simply diffused to wherever it was needed. It turns out the most important destination of all has a private delivery line. Subscribe to our newsletter ...

Cancer cells are subjected to high mechanical pressure that leads to a rupture of the nuclear envelope when migrating through narrow tissue structures, as in the case of metastasis. DNA would normally ...

Researchers have created an array of nanopillars that can breach the nucleus of a cell -- the compartment that houses our DNA -- without damaging the cell's outer membrane. This new 'gateway into the ...

When cancer cells are physically squeezed, they mount an instant, high-energy defense by rushing mitochondria to the cell nucleus, unleashing a surge of ATP that fuels DNA repair and survival. This ...

An international team of scientists has unveiled the most comprehensive model yet that explains how cells control the flow of materials in and out of their nuclei—solving one of biology's oldest ...

The cell nucleus goes a long way during an immune response, both literally and figuratively. The white blood cells in question are cytotoxic T lymphocytes (CTLs), also known as killer T cells. These ...

Animal cell and molecular biology examines how cells are built, how they process information and energy, and how they respond to their physical and chemical environments. At its heart is the cell ...

The cell nucleus goes a long way during an immune response, both literally and figuratively. New research published in Science Immunology shows that in some white blood cells, this genetic storage ...

The outer membrane of the cell, meanwhile, remains undamaged. "This is exciting because we can selectively create these tiny breaches in the nuclear membrane to access the nucleus directly, while ...
