Peroxisome-proliferator-activated receptors (PPARs) are ligand-activated transcription factors that belong to the nuclear-hormone-receptor family. Three isotypes have been identified — PPARα, PPARβ/δ ...

Before seedlings can photosynthesize, they depend on fatty acids—and on peroxisomes to process them. Researchers discovered ...

Researchers at the University of Virginia (UVA) School of Medicine have uncovered a potential path to treatment for persistent COVID-19 symptoms impacting the lungs. The work, published in Science in ...

Cells are divided into specialized organelles that perform specific functions. The proper function of a healthy cell depends on the web of interactions between organelles and all of their associated ...

Stem cells have gained fame for their ability to become any type of cell in the body. Unlike specialized cells with very specific functions that only make more of themselves, stem cells are ...

For most of their lives, plants get their energy from photosynthesis. But during the seed to seedling stage, when they can't absorb light just yet, they rely on other sources, like fatty acids. To ...

The ability to make membrane-bound organelles is a defining characteristic of eukaryotic cells -- cells that constitute the bodies of all animals, plants and fungi on Earth. Membranes create ...

A fundamental question in cell biology is: how do cells get rid of waste? Every living cell continuously generates metabolic by-products, damaged macromolecules and potentially toxic compounds that ...

Rice University scientists used advanced CRISPR techniques to study PEX11, a protein coded by five genes in Arabidopsis plants, revealing its role in controlling peroxisome growth during the ...

Plants spend most of their lives using photosynthesis to make energy. However, in the earliest phase after a seed begins to grow, they cannot yet ...
