Mitochondrial calcium uptake.
Calcium (Ca(2+)) uptake into the mitochondrial matrix is critically important to cellular function. As a regulator of matrix Ca(2+) levels, this flux influences energy production and can initiate cell death. If large, this flux could potentially alter intracellular Ca(2+) ([Ca(2+)]i) signals. Despite years of study, fundamental disagreements on the extent and speed of mitochondrial Ca(2+) uptak...
متن کاملCATION UPTAKE PROPERTIES OF CALCIUM ALUMINOSILICATE
In this study, the effect of different parameters such as time and temperature of calcination and milling on the formation of calcium aluminosilicates was investigated. Raw materials used in this study were calcium carbonate and kaolin in high purity. Powder X-ray diffraction patterns were obtained from all samples after heat treatment at various temperatures and times. To study the microstruct...
متن کاملInhibition of mitochondrial calcium uptake 1 in Drosophila neurons.
The mitochondrial calcium uptake 1 (MICU1) is a regulatory subunit of the mitochondrial calcium uniporter that plays an important role in calcium sensing. It contains two EF-hand domains that are well conserved across diverse species from protozoa to plants and metazoans. The loss of MICU1 function in mammals is attributed to several neurological disorders that involve movement dysfunction. The...
متن کاملAcidification reduces mitochondrial calcium uptake in rat cardiac mitochondria.
Cardiac ischemia-reperfusion (I/R) injury is accompanied by intracellular acidification that can lead to cytosolic and mitochondrial calcium overload. However, the effect of cytosolic acidification on mitochondrial pH (pHm) and mitochondrial Ca2+ (Cam2+) handling is not well understood. In the present study, we tested the hypothesis that changes in pHm during cytosolic acidification can modulat...
