Normal cells have special self-regulating activities; Positive regulators such as cyclins and cyclin-dependent kinases (cdk) which induce proliferation and growth, and negative regulatory components such as cdk inhibitors are tightly regulated to control homeostasis. Thus, many trials have been performing for the development of the diagnosis of cancer, therapeutics and screening system of anti-cancer agents. For the screening of anti-cancer agents target-oriented to inhibit the function and expression of cancer oncogenes E6, E7, this study is elucidated on the applications of screening systems to isolate new factors to inhibit the infection of virus and activity of oncogenes. Tetramethoxy flavones isolated from Artemesia and korean natural plants and their synthetic derivatives are being used to develope modulators for immune diseases of women infected by cervical carcinoma-inducing viruses. Over 50% of human cancers screened to date are caused by mutation of tumor suppressors p53 and Rb proteins. Other cancers have been described that p53, pRb have been inactivated by virus infection and other kinds of cell cycle modulators and tumor suppressors are inactivated or mutated by mutation or inactivation of proteins related to cell cycle. Therefore, based on interaction between oncogenes and tumor suppressors, proteins or genes related to cell cycle will be informed and much more progresses will be performed in the development of anti-cancer agents. Efficient various systems for screening modulators targeting to oncogenes from cancer cells and natural products have been elucidated based on interactions between oncogenes and tumor suppressors(ELISA based on interaction between oncogene E6 and E6AP; ELISA based on interaction between oncogene E6 and p53; ELISA based on interaction between oncogene E7 and Rb; ELISA based on interaction between oncogene E6AP and p53; Screening assay systems using transactivation of heterologous viral promoters of oncogenes E6, E7). Those systems can be applied to the screening of anti-oncogenes of HPV, or anti-inflammatory modulators and preventive and therapeutic trials to cervical cancers. Several screening systems to isolate new factors or materials to inhibit the function and activity of oncogenes have been used. In this study, we have produced, purified the oncogenes (E7, E6, E6AP) and tumor suppressor proteins(p53, Rb) by using gene recombination technology, and further established the in vitro binding screening system to test the function of these genes. These technologies were patented (277661, 329936, 380288). This study is focused as follows; By using in vitro systems based on the interactions between oncogenes and tumor suppressors (ELISA based on E6-p53 binding; ELISA based on E6AP-p53 binding; ELISA based on E6-E6AP binding; ELISA based on E7-Rb binding), cell cycle or apoptosis modulating factors can be identified and some of these factors can be used as putative anti cancer agent which can inhibit the growth of cancer cells or inhibit the inflammatory responses. These systems will be also used to screen the anti-cancer agents from the extracts of natural products such as oriental medicines and plants. By using these systems, several modulating factors such as tetramethoxy flavones are being isolated and characterized. Some of these factors are being derived from chemical synthesis and investigated how these factors are effective against infection and cervical cancers.
