Construction of the endoplasmic reticulum
To study the construction of the ER, we used the microtubule-disrupting drug nocodazole to induce the complete breakdown of ER structure in living cells followed by recovery in drug-free medium, which regenerates the ER network within 15 min. Using the fluorescent dye 3,3'-dihexyloxacarbocyanine iodide to visualize the ER, we have directly observed the network construction process in living cel...
متن کاملGating Behavior of Endoplasmic Reticulum Potassium Channels of Rat Hepatocytes in Diabetes
Background: Defects in endoplasmic reticulum homeostasis are common occurrences in different diseases, such as diabetes, in which the function of endoplasmic reticulum is disrupted. It is now well established that ion channels of endoplasmic reticulum membrane have a critical role in endoplasmic reticulum luminal homeostasis. Our previous studies showed the presence of an ATP-sensitive cationic...
متن کاملCytoplasmic acidification reduces potassium channel activities in the endoplasmic reticulum of rat hepatocytes
Introduction: Intracellular pH (pHi) regulates essentially all aspects of cellular activities. However, it is unknown how endoplasmic reticulum (ER) potassium channels sense pHi. In this study, we investigate the direct effects of pHi on ER potassium channels. Methods: We used channel incorporation into the bilayer lipid membrane method. L-α-phosphatidylcholine, a membrane lipid, was extrac...
متن کاملThe Endoplasmic Reticulum
Original Findings on Cultured MateriaL--The relatively short history of the endoplasmic reticulum started 10 years ago, in 1945, when Porter, Claude, and Fullam (1), noted the presence of a "lace-like" reticulum in the ground substance of ceils grown in tissue culture and examined in toto in the electron microscope. In describing their findings, these authors mentioned that "at higher magnifica...
