Table 1 HMCLs’ characteristics and sensitivity to RITA and nutlin3a

From: RITA (Reactivating p53 and Inducing Tumor Apoptosis) is efficient against TP53 abnormalmyeloma cells independently of the p53 pathway

  1. HMCLs’ characteristics were previously reported (21). RITA and nutlin3a LD50 values (dose that killed 50% of cells in 72 h) were determined as described within the Methods section. SD: standard deviation. TP53 cDNA sequencing was performed after 2 overlapping PCR assays. HMCLs displaying TP53 mRNA sequence lacking exons (NAN6, NAN7, NAN8) or displaying mutation impairing exon splicing (L363) or nonsense mutations (NAN1 and ANBL-6) were gathered and called “truncated”. lack of exons 7, 8 and 9. *no amplification after exon 7. $L363 cells displayed a point mutation in exon7/intron 7 splicing junction (base C782G) impairing splicing of intron 7.
