Cell viability according MTT test for oligonucleotides: (A–C)—biHD1; (D–F)—biHD1-C3; (G–I)—biHD1-T4A,T20A; (J–L)—biHD1-5′-Δ2G; results are presented for human cancer cell lines RL-67 (A,D,G,J), U87 (B,E,H,K), and embryonic fibroblasts (C,F,I,L) after 72 h incubation with different concentrations of oligonucleotides: Control experiment without oligonucleotides, 0.10, 1.0, and 10 μM. Data are presented as mean ± S.D. * marks p < 0.05 compared with control (w/o oligo).
