WebMay 4, 2024 · Parvalbumin is one of the most important cytosolic Ca2+ buffers in skeletal muscle. Butera et al. demonstrate that the profound mitochondria rearrangement in muscle fibers, caused by parvalbumin ablation, increases mitochondria Ca2+ buffering capacity. This impinges on the PGC-1α4 pathway, counteracting atrophy and inducing muscle fiber … WebThis result also provides an analytical estimate of the cytosolic Ca2+ domain concentration ([Ca2+]d) near a channel pore and shows the dependence of [Ca2+]d on moderate concentrations of endogenous mobile buffer, Ca2+ indicator dye, and bulk cytosolic Ca2+. Assuming a simple relationship between ...
