2) Given that E6 inactivates p53-dependent pathways, cervical
cancer cells are particularly resistant to traditional treatments
such as chemotherapy, the search is ongoing for new alternative
therapeutics to be used in conjunction with current
chemotherapeutic drugs. One such candidate is the plant flavonoid
Luteolin. In 2014, Ham et al evaluate the effectiveness of Luteolin
