Abstract
Cervical cancer is one of the leading causes of female death from cancer worldwide with about 500,000 deaths per year. A strong association between certain human papilloma viruses (HPV types 16 and 18) and cervical cancer has been well known. An extract of natural products, named as Somatid, has been used to investigate whether this agent has the ability of inhibiting the oncogenes E6 and E7 of HPV type 16. This Somatid inhibited the proliferation of human cervical cancer cell lines (C-33A, SiHa, CaSki) and HaCaT keratinocytes in a dose response manner. In vitro binding assay and ELISA showed that Somatid inhibited the in vitro biding of E6 and E6AP which are essential for the binding and degradation of the tumor suppressor p53. In addition, Somatid inhibited the in vitro binding of E7 and Rb which is essential tumor suppressor for the control of cell cycle. The levels of mRNA for E6 and E7 were also decreased by Somatid. Our data suggested that Somatid inhibited the oncogenecity of E6 and E7 of HPV 16 type, thus can be used as a putative anti-HPV agent for the treatment of cervical carcinomas caused by HPV.
