In the article “Acute Induction of Conserved Synaptic Signaling Pathways in Drosophila melanogaster,” by C. A. Hoeffer, S. Sanyal, and M. Ramaswami, which appeared on pages 6362-6372 of the July 16, 2003 issue, one of the gel images in Figure 7a is shown backward, erroneously depicting the data for DFos expression. The correct version of Figure 7, as well as the legend, is printed here.
Induction of Drosophila homologs of the immediate-early genes Fos (kayak) and c/EBP (slbo) after seizure induction and ERK activation in Drosophila. a, In mRNA extracted from entire fly heads, DFos is increased 2.7-fold in treated comttp7; CaP60AKum170Drosophila when compared with wild-type animals (n = 11; p = 0.004). b, Dm-c/EBP is increased 2.1-fold in comttp7; CaP60AKum170Drosophila when compared with wild-type animals (n = 10; p = 0.017). The gel bands beneath each graph show RT-PCR products at identical cycles just as the Q-PCRs entered log-linear growth phase for each comparison. (+, treated; -, untreated). See Table 1 for additional data.
