Figure Lengend Snippet: Representative xenograft photomicrographs of hematoxylin-eosin ( A , B ) and Sirius red ( C , D ), polarized Sirius red ( E , F ) morphological stainings and of Ki67 expression ( G , H ) on vehicle cryopass-laser-treated mice ( A , C , E , G ) and melatonin cryopass-laser-treated mice ( B , D , F , H ). Bars: 8 μm. The green asterisks indicate the extravascular red blood cells, the yellow arrows indicate the tumor cells nuclei with irregular shape, the blue arrows indicate collagen fibers, and the red arrows indicate Ki67 positivity. Graph ( I ) summarizes the number of Ki67 positive cells/field measurement. * p ≤ 0.05 vs. melatonin cryopass-laser group.
Article Snippet: The xenograft sections were incubated for 1 h at 37 °C and for 1 h at room temperature with the following primary antibodies: rabbit polyclonal antibody against anti-Ki67 (diluted 1:100; Abcam, Cambridge, UK); anti-CD31; goat polyclonal antibody against MMP2 (diluted 1:200; Santa Cruz Biotechnology, Dallas, TX, USA); rabbit polyclonal antibody against SIRT1 (diluted 1:250; Abcam, Cambridge, UK); rabbit polyclonal antibody against PGC-1α (diluted 1:400; Abcam, Cambridge, UK); rabbit polyclonal PPAR γ (diluted 1:500; Abcam, Cambridge, UK; and rabbit polyclonal against NF-kB (diluted 1:350; Abcam, Cambridge, UK).
