Although the wild-type flies are not paralyzed at 38 °C, the syx3–69 mutant flies are. However, the syx3–69 flies recover rapidly to standing position within 2–3 min once returned to the permissive temperature. The quantification of the recovery kinetics is shown in (B). Error bars in this and all other figures indicate the standard errors.(C) The paralyzed syx3–69 mutant flies remain capable of responding to stimuli via the polysynaptic giant fiber (GF) pathway. The flies are anchored on a glass slide upside down with modeling clay while a stimulating electrode is inserted into one of the compound eyes (arrows). The syx3–69 fly constantly shakes its legs, head, and abdomen while paralyzed at 38 °C. In response to electrical stimulation of the giant fiber neuron, the mutant fly extends its legs phase-locked with each stimulus. However, the Shits1 fly is completely paralyzed and does not respond to the stimuli at the same restrictive temperature. The right-most panels summarize the cumulative spontaneous and electrical stimulation–evoked movements of legs in syx3–69 flies and the lack of leg movement in Shits1 flies. These behavioral observations strongly indicate that exposing the syx3–69 fly to 38 °C does not block synaptic transmission. See also Videos S4 and S5.(D) Recordings from indirect flight muscles confirm that synaptic transmission is not blocked in syx3–69 flies at the restrictive temperature. Action potentials in DLMs driven by polysynaptic stimuli along the giant fiber pathway remain the same in the syx3–69 mutant fly as in the wild-type control fly before, during, and after exposure to the restrictive temperature. Synaptic-induced high-frequency action potentials are often observed in both the wild type and the syx3–69 mutant (unpublished data).

(A) The overexpression of CycE is able to induce ectopic BrdU incorporation with a high efficiency in the anterior part of the NPR, but less so the posterior, where only a few cells enter S phase. (B) The PCNA-GFP reporter (green) is active (arrows) in the CycE overexpression clones (marked by presence of β-gal in red) within the NPR. (C) In dE2F1 overexpression clones there is BrdU incorporation only in the anterior part of the NPR. (D) The overexpression of CycE and dE2F1 can induce incorporation of BrdU in anterior and posterior cells of the NPR. (E) CycA overexpressing cells incorporate BrdU in any part of the NPR, but with a higher efficiency in the posterior part, where most cells are BrdU positive. (F) Simultaneous overexpression of CycE and CycA induces a high proportion of BrdU incorporation in any part of the NPR.", "subfigure_path": "/datasets/PMC-15M/filtered_biomedica/filtered_v4/subfigures_final/subfig_0_filelist_commercial_batch_0_105-PMC1810524-4-1471-213X-7-13-2.jpg" }
