Skin stem cells get moving for enhanced skin regeneration

Although sometimes hard to accept, with aging, many things in our bodies change. One of these is the ability of the skin to regenerate. Old skin is just not as good as young skin at healing wounds. However, the molecular ...

How a metabolic pathway promotes breast cancer metastasis

A metabolic pathway that is up-regulated in certain breast cancers promotes the disease's progression by activating a cell signaling protein called Arf6, according to a paper published in the Journal of Cell Biology. The ...

Mouse study links heart regeneration to telomere length

Researchers at the Spanish National Center for Cardiovascular Research have discovered that the ends of heart muscle cell chromosomes rapidly erode after birth, limiting the cells' ability to proliferate and replace damaged ...

Enzyme ensures thick insulation

ETH researchers have revealed that Schwann cells in the peripheral nervous system largely produce their own fatty acids in order to create electrical insulation for nerve fibres. This process relies on an enzyme whose absence ...

Mobilizing mitochondria may be key to regenerating damaged neurons

Researchers at the National Institute of Neurological Disorders and Stroke have discovered that boosting the transport of mitochondria along neuronal axons enhances the ability of mouse nerve cells to repair themselves after ...

Researchers uncover new target to stop cancer growth

Researchers at the University of Wisconsin-Madison have discovered that a protein called Munc13-4 helps cancer cells secrete large numbers of exosomes—tiny, membrane-bound packages containing proteins and RNAs that stimulate ...
