although pep was more effective than blm against blm-resistant hela cells ( hela-blmr ) , neoplastic cells derived from salivary gland ( hsg ) and melanoma cells ( mec ) , these three cell lines were still at least ten times more resistant to pep than epidermoid carcinoma cell lines including hela cells by comparison of ic50 , and showed lower cellular accumulation of 3h-pep as compared with hela cells .
