C. Western blot for NHP2 in SI14/TEL+, SI24/ALT+ and 8G12/ALT+ cell lines treated with DMSO or 10 μM MG132 for 6 h. β-Actin served as loading control. Quantifications are shown on the right, normalized to β-Actin and to SI14/TEL+ cells (n=5). Statistical analyses were performed with Student's two-tailed unpaired t-test. Data information: Data are presented as mean ± SD.
