Previous studies have demonstrated that the palindromic motif, when N-terminally functionalized with peptide amphiphilic cationic sequences, such as RRWQWR-Ahx-RWQWRWQWR and RLLRRLLR-Ahx-RWQWRWQWR, exhibited a significant and selective cytotoxic effect in cervical cancer cells, HeLa and Ca Ski. The gene discussed is NR0B1; the disease is cervical cancer.
