Domoic Acid-Induced Neurotoxicity Is Mainly Mediated by the AMPA/KA Receptor: Comparison between Immature and Mature Primary Cultures of Neurons and Glial Cells from Rat Cerebellum
Figure 1
Changes in the mRNA levels of NF-68 and 200 in primary cultures of CGCs exposed to domoic acid (5 μM, 10 μM, and 20 μM) at 1 DIV (immature cultures) or at 7 DIV (mature cultures) for 3 or 10 days. Note the significant downregulation of (a) NF-68 in immature cultures after 10 days of exposure, (b) NF-68 in mature cultures, (c) NF-200 in immature cultures, and (d) NF-200 in mature cultures. Gene expression levels were normalized to the standard calibrator, the housekeeping gene 18S rRNA and the mRNA expression at 1 DIV. Data represent mean ± S.E.M. of three independent experiments performed in duplicates. ++++++ comparing control cultures at 3 and 10 days. * ** *** comparing treated to control (untreated) cultures.
