Figure Lengend Snippet: In vivo test of Bio-nFer on neuT mice. Bio-nFeR was administered at 100 mg/kg daily, 5 days/week, from week 14 to week 32 PB by oral gavage. (A) Time-course of tumor development in the mammary glands over time, post first tumor occurrence in vehicle (black) versus Bio-nFeR (red) mice. (B) Time to reach 10/10 mammary gland invasion in vehicle (black) versus Bio-nFeR (red) mice, post birth. (C) Average tumor volume at sacrifice in vehicle (black) versus Bio-nFeR (red) mice. (D) Scatter plot of average tumor burden (volume) at sacrifice in Bio-nFeR versus control mice. (E) Average tumor weight at sacrifice in vehicle (black) versus Bio-nFeR (red) mice. (F) Scatter plot of average tumor burden (weight) at sacrifice in vehicle versus Bio-nFeR mice. (G) Left: representative images of immunofluorescence staining of mammary tumors harvested ex vivo from vehicle-treated and Bio-nFeR-treated mice (20x, 0,7x zoom magnification, scale bar 50 μm). Ki67 (pseudocolored in green) and DAPI nuclear staining (blue); Right: proliferation index by Ki67 nuclear staining on sections. Data in A represent Mean ± SEM, *** P < 0.001 by paired Student’s t test with Wilcoxon test. Data in B were analyzed by Long-rank (Mantel-Cox) test, * P < 0.05 and. Data in C , D , E , F represent Mean ± SEM, * P < 0.05 and ** P < 0.01 by unpaired Student’s t test with Welch correction. Data in G represent Mean ± SD, * P < 0.05 by unpaired Student’s t test with Welch’s correction
