Ⅰ. Background and purpose : More than 90% human cancer are induced in epithelial cells. HPV infection results in cancer development. HPV E7 oncogene enhances COX-2 expression, proinflammatory cytokine IL-32 expression, followed by activation of PTEN, PI3K/Akt, reading to the oncogenesis of cervical cancer. This study was focused on identification of the optimized modulators and establishment of inhibiting methods against cervical cancer mediated via regulating signaling pathways.
Ⅱ. Contents and Scope :
1) Investigation of expression patterns of E7, PPARγ , PTEN, PI3K/Akt, and IL-32 in epithelial cells and cervical cancer tissues and cells. Analyses of expression profiling during tumorigenesis and corelation between expression patterns and oncogenesis.
2) Modulating mechanisms targetting to HPV oncogene E7, PPAR-γ , PTEN, PI3K/Akt, IL-32
- analysis of E7 induced COX-2, IL-32 expression
- Analysis of controling cervical cancer using E7 siRNA, PPAR-γ agonist, IL-32 aptamer, IL-32 siRNA.
- Analyses of feedback mechanism between E7 induced IL-32 isoform and COX-2 expression, and expression of PPAR-γ, PTEN, PI3K/Akt, IL-32 using multiple targeting modulators (E7 siRNA, PPAR-γ agonist, COX-2 inhibitor, IL-32 siRNA or aptamer, etc).
Ⅲ. Results : Identification of optimized multiple targeting modulators and analysis of controliing methods against cervical cancer using multiple targeting modulators
Ⅳ. Application : Bioresourses (PPAR-γ agonist, IL-32 aptamer, IL-32 siRNA, E7 siRNA, etc)
