Figure 3. CTX, CA4 and CTX-23 lead to glioma cell shrinkage.
(A) Human glioma cells U251 were treated with CTX, CA4 or CTX-23 and membrane extensions were monitored. Incubation time for CTX, CA4 or CTX-23 was 24 hours. Nuclei are given in red, actin is displayed in green. Scale bar represents 50 μm. (B) Top, Quantification of CTX induced cell shrinkage. Both CTX and its derivatives significantly reduced cell volume compared to controls. Bottom, Quantification of CTX induced nuclei size increase. Both CTX and its derivatives significantly increased the nuclei size of glioma cells compared to controls. Quantification is given from three independent experiments. Means are given as ± SD, n = 10 per group, *P < 0.05 (Student’s unpaired t-test).
