AnaSpec rabbit anti-gfap (1:200)
DAAkt1-induced gliomas. (A) Gross and histologic findings. (a,b) Glioma-bearing 3-month-old Ptf1aGal4/UASGFP-UASDAAkt1 zebrafish with bent body and visible bumps at the head, showing strong GFP expression on merged bright and fluorescence images (inlets). (c) Hematoxylin and eosin stains of cerebellum in control zebrafish. (d–i) Hematoxylin and eosin stains of gliomas. (d and e) Small tumors (boundaries by red arrowheads) at periventricular area showing invasion into 4th ventricle. (f) A large glioma replacing almost the whole cerebellum. (g) A large glioma showing invasion into the midbrain. (h) A high-grade glioma showing increased vascularity (black arrowhead). (i) A high-grade glioma showing necrosis (red arrowhead). (j) IHC for <t>GFAP</t> showing robust expression. (k) IHC for Akt1 on a small tumor invading 4th ventricle showing expression at tumor. (l) ISH for DAAkt1 showing stronger expression at the hypercellular area. (B) Increased proliferation in DAAkt1-induced gliomas. IHC indicates highly frequent positivity <t>to</t> <t>PCNA,</t> which is even higher in high-grade tumor. Tumors occasionally show positive staining to PHH3, a mitotic marker. BrdU labeling also reveals frequently positive cells. (C) Proliferation analyses in the pre-neoplastic cerebellum of 2-month-old zebrafish. Reactivity at the intestinal cells is used as an internal positive control (Inlets). Cells at the ventricular lining and the intermediate layer frequently reveal immunoreactivity to proliferative markers. The non–tumor-bearing cerebellum of DAAkt1-expressing zebrafish is not associated with increased proliferation. Average numbers of positive cells counted at the periventricular are 4.5 ± 2.2 and 4.7 ± 2.6 for PHH3 and 18.7 ± 6.8 and 19.9 ± 6.9 for BrdU in Ptf1aGal4/UASGFP and Ptf1aGal4/UASGFP-UASDAAkt1 zebrafish, respectively, which are not significantly different. Bars, 50 μm. (D) Activation of Akt downstream components in nonneoplastic DAAkt1-expressing cerebellum. IHC analyses reveal slightly increased expression of phospho-mTOR, -RS6K, and -4EBP1 in cells at the ventricular and periventricular zone.

Cells at the ventricular lining and the intermediate layer frequently reveal immunoreactivity to proliferative markers. The non–tumor-bearing cerebellum of DAAkt1-expressing zebrafish is not associated with increased proliferation. Average numbers of positive cells counted at the periventricular are 4.5 ± 2.2 and 4.7 ± 2.6 for PHH3 and 18.7 ± 6.8 and 19.9 ± 6.9 for BrdU in Ptf1aGal4/UASGFP and Ptf1aGal4/UASGFP-UASDAAkt1 zebrafish, respectively, which are not significantly different. Bars, 50 μm. (D) Activation of Akt downstream components in nonneoplastic DAAkt1-expressing cerebellum. IHC analyses reveal slightly increased expression of phospho-mTOR, -RS6K, and -4EBP1 in cells at the ventricular and periventricular zone.
