Fig. 8. Nucleolin protein in NB4-LR1 cells after differentiation and apoptosis. (A) Differentiation (+) of NB4-LR1 cells was obtained by a 72-hour treatment with a combination of ATRA (1 µM) and 8-CPT-cAMP (200 µM). (B) Apoptosis was induced either by a 24-hour treatment with oridonin (4 µg/ml) or a 24-hour treatment with As2O3 (5 µM). Proteolytic fragments are indicated.
