The endoplasmic reticulum is the protein-making factory within cells consisting of tightly stacked sheets of membrane studded with the molecules that make proteins. Now, researchers have refined a new ...

The endoplasmic reticulum (ER) forms tight membrane contact sites (MCSs) with several organelles in animal cells and yeast. The function of MCSs between the ER and mitochondria and endosomes are ...

The structure of plastids in the root cap of cress and maize was studied by low- and high-voltage electron microscopy after staining their membranes with a mixture of zinc iodide and osmium tetroxide.

Endoplasmic reticulum (ER) proteostasis is regulated by the adaptive unfolded protein response (UPR) pathway, which determines cell fate and maintains cell structure and function Stress (hypoxia, ...
