2Endoplasmic reticulum: structure and function TheERis a major endomembrane compartment consisting of an extensively folded tubulovesicular membrane network supported by the gel-like cytoplasmic matrix (reviewed inEnglish and Voeltz, 2013). There are two types of ER in a cell: the smooth ER and th...

The endoplasmic reticulum is the major site of synthesis in the cell. It is a system of flattened sacs (cisternae) that are continuous with the outer nuclear envelope. Its physiological function has a very close association with that of the Golgi apparatus and together, they form the secretory...
The smooth endoplasmic reticulum is also involved in the transfer of molecules produced in the rough ER to the Golgi complex. Lipid synthesis The smooth endoplasmic reticulum is the major site for lipid synthesis, particularly at themembrane contact sites(MCS). MCS are areas where ER membranes mak...
Step-by-Step Text Solution:1. Understanding Endoplasmic Reticulum (ER): - The endoplasmic reticulum is a vital membrane-bound organelle found in eukaryotic cells. It plays a crucial role in various cellular
Canonically, adrenergic stimulation activates myosin light chain kinase (MLCK) and induces PASMC contraction by activating calcium-dependent channels in the endoplasmic reticulum to increase cytosolic Ca2+ concentration ([Ca2+]).41 Several mechanosensitive calcium channels have been shown to play a role ...
Smooth ER Function and Appearance Under a microscope you view a cell with an extensive smooth endoplasmic reticulum present. What would you see and how would you describe it? Smooth ER gets its name, as do so many things in anatomy and microanatomy, not from how it would really feel or ...
These phenotypes are also accompanied by the loss of the contractile phenotype coinciding with the activation of endoplasmic reticulum (ER) stress, autophagy and cell death18. Similarly, Prmt1 ablation also caused cell death of smooth muscles in aortas, likely contributing to aortic dilation. In ...
In contrast, synthetic cells are found in development and repair processes, such as in atherosclerotic lesions, and their cytoplasm contains few filament bundles but large amounts of organelles, including rough endoplasmic reticulum (RER) and Golgi. Their function is almost exclusively related to ...
which results in activation of L-type Ca2+channels and Ca2+entry. This also then leads to activation of Ca2+release channels expressed in the membrane of thesarcoplasmic reticulum. The L-type Ca2+channel is mechanosensitive, suggesting that smooth muscle cells are not only motor organs but also...
