Astrocytes play a critical neurotrophic and neuroprotective role in the brain, and improper function of these cells may contribute to the onset of neurodegenerative diseases. Because astrocytes are known to be enriched with Cu chaperone proteins, it is important to understand the factors that may lead to cytotoxic effects of Cu on astrocytes. In this(More)
Pyrrolidine dithiocarbamate (PDTC) is a metal chelator. Biologically, slight toxic affects EC50, 100+/-5.9 microM are observed when added to cultured HL-60 cells. CuCl2 at a physiological concentration (1 microM), but not FeCl2, Pb potentiated the cytotoxic effect of PDTC by 700 fold (EC50, 0.14+/-0.02 microM). Furthermore, results indicated that the(More)
The perinatal period is critical for β-cell mass establishment, which is characterized by a transient burst in proliferation to increase β-cell mass in response to the need for glucose homeostasis throughout life. In adulthood, the ability of β-cells to grow, proliferate, and expand their mass is also characteristic of pathological states of insulin(More)
