The Golgi apparatus plays a central role in lipid and protein post-translational modification and sorting. Morphologically the organelle is heterogeneous and it is possible to distinguish stacks of flat cysternae (cis- and medial Golgi), tubular-reticular networks and vesicles (trans-Golgi). These morphological differences parallel a distinct functionality(More)
Calcium storage, release, and reuptake are essential for normal physiological function of muscle. Several human skeletal muscle disorders can arise from dysfunction in the control and coordination of these three critical processes. The release from the Sarcoplasmic Reticulum stores (SR) is handled by a multiprotein complex called Calcium Release Unit and(More)
The Golgi apparatus (GA) is a dynamic intracellular Ca(2+) store endowed with complex Ca(2+) homeostatic mechanisms in part distinct from those of the endoplasmic reticulum (ER). We describe the generation of a novel fluorescent Ca(2+) probe selectively targeted to the medial-Golgi. We demonstrate that in the medial-Golgi: (i) Ca(2+) accumulation takes(More)
Mitochondria are intracellular organelles involved in several processes from bioenergetics to cell death. In the latest years, ion channels are arising as new possible targets in controlling several cellular functions. The discovery that several plasma membrane located ion channels have intracellular counterparts, has now implemented this consideration and(More)
The activity of granulosa cells derived from different sized follicles surrounding oocytes of apparently comparable maturity was evaluated in hyperstimulated ovaries. Granulosa cells were obtained from women undergoing gamete intra-Fallopian transfer procedures who had been treated with gonadotrophin-releasing hormone analogue and gonadotrophins. Only(More)
