Effect of nanotubes with different diameters on the apoptosis of U87 cells.

Notes: (A) Expression of Bcl-2, Bax, and caspase-3 in U87 cells cultured on nanotubes with different diameters without annealing. (B) Statistical analysis of Bcl-2, Bax, and caspase-3 expression. *P<0.05, compared with the 20 nm nanotubes. (C, D) Immunostaining of caspase-3 in U87 cells cultured on nanotubes with different diameters without (C) and with (D) annealing.

Abbreviations: GAPDH, glyceraldehyde-3-phosphate dehydrogenase; Ti, titanium.
