Figure Lengend Snippet: Bevacizumab treatment concurrent with nab-paclitaxel chemotherapy is the most effective regimen for inhibiting tumor growth and metastasis. (A, B) Mice bearing 435-LuC + tumors of 450 mm 3 in volume were treated with bevacizumab (4 mg/kg) using three different combination regimens with nab-paclitaxel (10 mg/kg, three cycles of daily for five consecutive days). (A) Schematic illustration of experimental design describing different regimens assessed in this study. Group 1 received three cycles of nab-paclitaxel followed by bevacizumab for the duration of the study, group 2 received bevacizumab concurrent with nab-paclitaxel and both drugs were discontinued at the end of three cycles of nab-paclitaxel, and group 3 received bevacizumab throughout three cycles of nab-paclitaxel and for the duration of the study. (B) Black arrows indicate the start of each cycle of nab-paclitaxel treatment. Data are presented as the mean tumor volume ± SE per group at the indicated days after implantation. Frozen sections from control- (C, top) and nab-paclitaxel-treated (C, bottom) tumors were stained with anti-VEGF-A antibodies and counterstained with 4′,6-diamidino-2-phenylindole to visualize the nuclei. Images were acquired at a constant exposure setting and total fluorescent intensity of VEGF-A staining from control (D, top) and treated (D, bottom) tumor sections was plotted using the ImageJ software as described in the Materials and Methods. Fluorescent intensity plots of representative images in (C) are shown. All images were acquired at a magnification of x200.

doi: 10.3892/etm.2018.5783

Figure Lengend Snippet: Molecular mechanisms by which curcumin regulates the IGF-1R signaling pathway and the expression of VEGF in HepG2 cells under CoCl 2 -induced hypoxia. The arrow and blocked arrow (no arrowhead) indicate stimulation and inhibition, respectively. The dotted arrow indicates the translocation of HIF-1α and HIF-1β. The dotted blocked arrow indicates the potential effects of curcumin not directly examined in the present study. It was concluded that curcumin may suppress the expression of HIF-1 and VEGF by targeting IGF-1R or its downstream signaling pathways.
