Figure Lengend Snippet: The microscopic findings [Hematoxylin and Eosin (H&E) staining and immunohistochemical staining of the resected tumor]. H&E staining (A) Low-power (×40) and (B) high-power (×400) views showed moderate stromal hypercellularity with mild nuclear atypia and mild pleomorphism of the spindle cells. Focal mildly atypical epithelial hyperplasia was also noted. Stromal overgrowth was absent. Immunohistochemical staining of (C) the phyllodes tumor and (D) normal breast tissue using rabbit polyclonal anti-insulin-like growth factor II (IGF-II) antibodies. The tumor cells, but not the normal breast tissue, were diffusely immunopositive for IGF-II.

Figure Lengend Snippet: Western blotting of high-molecular-weight IGF-II. Lane 1, serum from a healthy control; lane 2, serum from the patient collected preoperatively; lane 3, serum obtained 3 days after the resection of the tumor; lane 4, phyllodes tumor tissue. Large amounts of high-molecular-weight IGF-II were detected in the serum collected preoperatively (lane 2) and in the tumor tissue (lane 4) but not in serum collected postoperatively (lane 3) or a serum sample from a healthy control (lane 1).

Figure Lengend Snippet: Fig. 1. IGF-2 morpholinos efficiently and specifically knockdown IGF-2 in vivo. (A) Phenotype of (a) control injected and (b) IGF-2(a+b) morphant embryo at 24 hpf. IGF-2(a+b) morphant embryos are ventralised with a shorter body, disrupted brain structures (double arrows), reduced eyes, disrupted somites and an expanded intermediate cell mass (arrow). (B) Western blot showing IGF-2 and alpha-tubulin at 24 hpf in (1) uninjected control embryos, (2) embryos injected with control morpholinos or (3) embryos injected with IGF-2(a+b) morpholinos. (C) Igf-2a and igf-2b mediate their effects on development in a synergistic fashion. (D) Co-injection of igf-2a or igf-2b RNA with the corresponding morpholino rescues the IGF-2 morphant phenotype. Rescued embryos display normal body size, eyes and brain structures at 24 hpf. Results shown are a summary of three independent experiments (n ≥ 80). Error bars indicate the standard deviation of the mean.
