Iron restriction keeps blood stem cells young, researchers find

As we age, our hematopoietic (blood-forming) stem cells (HSCs) become less able to produce new red and white blood cells and other vital blood components—contributing to chronic inflammation and accelerating the onset of ...

A novel pathway regulating lipid biosynthesis by fatty acids

Researchers have been studying the transcription factor, SREBP, a critical regulator of lipid biosynthesis. Precursor SREBP proteins, located in the endoplasmic reticulum (ER) of the cell, are transported through the Golgi ...

How eggs of the Zika-carrying mosquito survive desiccation

Eggs of the mosquito that carries Zika virus can tolerate extended desiccation by altering their metabolism, according to a new study published October 24th in the open access journal PLOS Biology by Anjana Prasad, Sunil ...

Scientists map the distribution of carnitine in muscle cells

Researchers from Tokyo Metropolitan University have developed a way of mapping the distribution of carnitine in skeletal muscle cells. Carnitine is a compound that helps transport fatty acids and reduce metabolic byproducts. ...

The missing link: Fatty acid metabolism impacts plant immunity

That healthy salad you ate for lunch contains fatty acids—surprised? Fatty acids, lipids, and fats in our food may sound undesirable, but they are foundational to human life and to the plants we consume. Their interaction ...
