Expression of E7 proteins encoded by carcinogenic, high-risk human papillomaviruses (HPVs) triggers increased expression of the histone H3 lysine 27 demethylase KDM6A. KDM6A expression is necessary for survival of high-risk HPV E7 expressing cells, including several cervical cancer lines. Here we show that increased KDM6A in response to high-risk HPV E7 expression causes epigenetic de-repressio...
background: cervical cancer has been shown to be highly associated with human papillomavirus (hpv) infection. the viral oncogenes e6 and e7 are constantly expressed by the tumor cells and are therefore potent targets for therapeutic genetic vaccination. in the present study, it was investigated the potential effect of hpv-16 e6, e7 and l1 co-administration to activate specific cytotoxic t lymph...
High-risk types of human papillomavirus (HPV) are considered the major causative agents of cervical carcinoma. The transforming ability of HPV resides in the E6 and E7 oncogenes, yet the pathway to transformation is not well understood. Cells expressing the oncogene E7 from high-risk HPVs have a high incidence of polyploidy, which has been shown to occur as an early event in cervical carcinogen...
The aim of this study was to assess the use of human papillomavirus (HPV) E6/E7 mRNA testing in the follow-up of women treated for cervical intraepithelial neoplasia (CIN) by conization and to compare the prognostic value of HPV E6/E7 mRNA to HPV L1 DNA and cytology. One hundred and forty-three women underwent cytological/histological testing, HPV...
background and aims: since the produced recombinant proteins by molecular genetics techniques commonly have some limitations in the application, chimeric protein are introduced. chimeric proteins have found widespread application for the study of protein folding, structure stability, function and immunogenisity. methods: according to the known immunomodulatory effect and structure of hsp70 mole...
It has been well established that platelets are associated with tumor progression and metastasis as they can support angiogenesis and prevent hemorrhage. As such, platelets may be an ideal target for enhancing anticancer immunotherapies. Thus, we hypothesized that inducing thrombocytopenia would increase the leakiness of tumor vasculature thereby facilitating the effective delivery of antigen-s...
Antigen-specific DNA vaccine immunotherapy is an attractive approach for the treatment of cancer since it has the potency to specifically eradicate systemic tumors without damaging the normal cells. However, DNA vaccine shows insufficient immune response for antigen presenting cells and has minimal clinical efficacies. Cryoablation therapy is the therapeutic application of extreme cold for loca...
Serine protease inhibitor 6 (SPI-6), also called Serpinb9, inhibits granzyme B and thus may provide a method for delaying apoptotic cell death in dendritic cells. We have previously enhanced DNA vaccine potency by targeting antigen to MHC antigen presentation pathways, using proteins such as Mycobacterium tuberculosis heat shock protein 70, calreticulin, domain II of Pseudomonas aeruginosa exot...
Persistent HPV infection is recognized as the main etiologic factor for cervical cancer. HPV expresses the oncoproteins E6 and E7, both of which play key roles in maintaining viral infection and promoting carcinogenesis. While siRNA-mediated targeting of E6 and E7 transcripts temporarily induces apoptosis in HPV-positive cells, it does not eliminate viral DNA within the host genome, which can h...
Human papillomavirus (HPV) infection is necessary but not sufficient for cervical carcinogenesis. Genomic instability caused by HPV allows cells to acquire additional mutations required for malignant transformation. Genomic instability in the form of polyploidy has been demonstrated to play an important role in cervical carcinogenesis. We have recently found that HPV-16 E7 oncogene induces poly...
