IF analyses of both MDA-MB-231 (breast cancer) and RH30 (alveolar rhabdomyosarcoma) cell lines showed movement of HuP10 from the nucleus to the mitochondria (Supplementary Figures S2A–B), during TRAIL-induced apoptosis, as determined by PARP cleavage (Supplementary Figures S2C–D and S4C–D). This evidence concerns the gene PUS10 and breast carcinoma.
