Figure Lengend Snippet: Inhibition of anchorage-independent growth of C6 glioma cells by hyaluronan oligomers or by overexpression of soluble HABPs. A: C6 cells (2 × 103 per well) were incubated for 1 week in soft agar in the presence or absence of 1, 10, or 100 μg/ml of hyaluronan oligomers, or 50 μg/ml of N-acetylglucosamine plus 50 μg/ml of glucuronic acid monomers, as described in Materials and Methods. The numbers of colonies >0.25 mm in size were counted. The results are presented as means of triplicates ± SD (control versus 10 or 100 μg/ml hyaluronan oligomers; P < 0.05). B: Western blot with antibody against phosphorylated Akt (p-Akt) or Akt for extracts of C6 cells grown in suspension. Lane 1, C6 cells alone; lane 2, C6 cells incubated with 100 μg/ml of chitin oligomers; lane 3, with 100 μg/ml of hyaluronan polymer (∼80 kD); lane 4, with 100 μg/ml of hyaluronan oligomers. C: C6 cells (2 × 103 per well) were infected with recombinant adenoviruses driving expression of β-galactosidase (β-gal), soluble CD44 (solCD44), or brevican link module (BLM), then assayed for growth of colonies in soft agar. The results are presented as means of three separate experiments, each performed in triplicate, ± SD (control versus soluble CD44 or brevican link module; P < 0.05).

Figure Lengend Snippet: Inhibition of glioma cell invasion by hyaluronan oligomers. A: C6 glioma cells (2 × 104 per well) were incubated in the presence or absence of 100 μg/ml of hyaluronan (HA) oligomers for 72 hours and the number of cells that invaded the reconstituted basement membrane matrix was measured at each 24-hour interval, as described in Materials and Methods. B: C6 rat glioma cells (2 × 104 per well), A172 human glioma cells (1 × 104 per well), and U87 human glioma cells (1 × 104 per well) were incubated in the presence and absence of 1 to 100 μg/ml of hyaluronan oligomers, 100 μg/ml of chitin oligomers, or 4 μg/ml of antibody against CD44 (Zymed), and the number of cells that invaded was measured after 24 hours. The results in B are presented as means of three experiments ± SD (control versus hyaluronan oligomers; P < 0.05 for each cell type).

Figure Lengend Snippet: a . A representative example of MRI analysis of C6 glioma growth in vivo. At 7 days post-implantation and before the treatment, an MRI imaging was performed (left column, 1–2 pictures T2 imaging, 3–4 pictures T1 imaging). The rats were randomized and either treated with 0.2 M OxAc or 0.3 M NaCl for additional 14 days. The MRI imaging was performed again at the end of the treatment (21 days post glioma implantation, right column, 1–4 pictures T2 imaging). b . Tumor volume of the rats before and after the treatment was calculated in n = 14 for control group and in n = 15 for the treated group using MRIcro software. OxAc-treated rats show significantly reduced tumor growth compared to the control group. * p < 0.01 (repeated measures ANOVA test)

Figure Lengend Snippet: A) The amount of HGF and VEGF determined by ELISA is higher in glioma C6 CM than in astrocyte CM, while the opposite is found for EGF. IP of HGF, VEGF or EGF reduces the amount of the growth factor present in CM. HGF: N = 4, F(3,12) = 26.54; VEGF: N = 3, F(3,8) = 20.98; EGF: N = 3, F(3,8) = 44.52; **P<0.01, ***P<0.001, ns = not significant; as assessed by one-way ANOVA followed by Bonferroni's post hoc test. B) ReNcells CX transmigration assay across RBMECs done by placing in the basal compartment of the Millicell, DMEM with HGF or EGF; or DMEM with neutralizing antibodies against HGF, VEGF or EGF; or astrocyte or glioma C6 CM with or without neutralizing antibodies against HGF, VEGF and EGF. Control corresponds to the transmigration induced by glioma C6 CM without the neutralizing antibodies against HGF (upper panel), VEGF (middle panel) and EGF (lower panel), and is considered as 100% transmigration. HGF: N = 3, F(6,14) = 124.7; VEGF: N = 3, F(4,10) = 275.5; EGF: N = 3, F(7,16) = 30.77; **P<0.01, ***P<0.001, ns = not significant; as assessed by one-way ANOVA followed by Bonferroni's post hoc test. C) RBMECs cultured for 8 h in DMEM with HGF and EGF have a TEER similar to that obtained with astrocyte CM. IP of VEGF reverses the decrease in TEER induced by glioma C6 CM whereas IP of EGF from astrocyte CM decreases TEER in a manner similar to that obtained with glioma C6 CM. HGF: N = 3, F(2,16) = 5.668; **P<0.01 with respect to astrocytes CM; VEGF: N = 3, F(2,20) = 14.64; *P<0.05 with respect to astrocytes CM; #P<0.05 with respect to glioma C6 CM; EGF: N = 3, F(3,30) = 23.07; *P<0.05, **P<0.01, ***P<0.001 with respect to astrocytes CM; # P<0.05, ## P<0.01, ### P<0.001 with respect to glioma C6 CM; + P<0.05, ++ P<0.01, +++ P<0.001 with respect to astrocytes CM + α-EGF; as assessed by one-way ANOVA followed by Bonferroni's post hoc test.
