New live-cell imaging data show that Telomir-1 markedly lowers intracellular iron levels at submicromolar concentrations in human keratinocytes, demonstrating potent cell penetration and ...

A new study integrated mathematical modeling with advanced imaging to discover that the physical shape of the fruit fly egg chamber, combined with chemical signals, significantly influences how cells ...

A naturally-occurring protein that tends to be expressed at higher levels in breast cancer cells boosts the effectiveness of ...

The structure of a cell’s nucleus has long served as a visible clue to whether a cell is healthy or affected by disease. While scientists have made major progress in understanding genes and their ...

Tiny tweaks in DNA folding can have big effects. A study from Umeå University shows that even the most subtle changes in DNA's shape have an important influence on gene activity and energy production.

A protein involved with cell death can be manipulated to slow or reverse tumor growth, a pair of new studies in mice found.

A new study from The University of Texas at Arlington has revealed how cells control their mitochondria—the "energy producers" of cells—during the process of cell death. The discovery sheds light on ...
