Considering the fact that TAT-mediated transduction of various non-overlapping peptides of CARP-1/CCAR1 suppressed the growth of HBC and lymphoma cells in vitro and in vivo [52, 53], and CARP-1/CCAR1 co-activates p53 to transduce ADR-dependent apoptosis in breast cancer cells [10], we speculated that CARP-1/CCAR1 likely regulates cell growth and apoptosis signaling by associating with additional key components of cell growth and cell cycle signal transduction pathways. This evidence concerns the gene CCAR1 and lymphoma.
