1. A recently developed method of measuring cytoplasmic Ca2+ buffering in intact red cells was applied to re-evaluate the intracellular Ca2+ binding properties of the Ca2+ chelators benz2 and BAPTA. Incorporation of the free chelators was accomplished by incubating the

In an attempt to probe the relationship between excitotoxicity and increases in intracellular calcium ([Ca2+]i), BAPTA-AM and its analogs were applied to cultured hippocampal neurons. Chelation of [Ca2+]i depressed and prolonged transient responses to glutamate and did not effect elevation
Gurpreet Kaur et al.
Biochemical and biophysical research communications, 450(1), 812-817 (2014-06-24)
We previously showed that increased intracellular calcium can modulate Importin (Imp)β1-dependent nuclear import of SRY-related chromatin remodeling proteins. Here we extend this work to show for the first time that high intracellular calcium inhibits Impα/β1- or Impβ1-dependent nuclear protein import
Wei Song et al.
Neuroscience letters, 589, 104-109 (2015-01-18)
The neuromuscular junction (NMJ) is established through initial contact of motor neuron axon with a skeletal muscle cell and the subsequent synaptic maturation. Previous studies have shown that cyclic AMP (cAMP) enhanced spinal neurons' survival and growth but inhibited synaptogenesis.
Vera Valakh et al.
Neurobiology of disease, 77, 13-25 (2015-03-03)
Nerve injury can lead to axonal regeneration, axonal degeneration, and/or neuronal cell death. Remarkably, the MAP3K dual leucine zipper kinase, DLK, promotes each of these responses, suggesting that DLK is a sensor of axon injury. In Drosophila, mutations in proteins
