Gene silencing with siRNA targeting E6/E7 as a therapeutic intervention against head and neck cancer-containing HPV16 cell lines.
Conclusion: Our results indicate that siRNA E6 and/or E7 may have potential as a gene-specific therapy for human papillomavirus (HPV) type 16 (HPV16)-related squamous cell carcinoma of the head and neck (HNSCC). Objectives: To evaluate the effectiveness of siRNA targeting E6 and/or E7 on the in vitro and in vivo growth suppression of HPV16-related HNSCC. Methods: HPV16-related HNSCC (UM-SCC47) cell lines were used for the present study. Expression of HPV viral oncogenes E6 and/or E7 and their cellular targets, p53 and pRb, was evaluated by real-time PCR, Western blotting, and immunofluorescence staining. To study the effec...

PEGylation of lipoplexes: The right balance between cytotoxicity and siRNA effectiveness.
In conclusion, the right balance between cytotoxicity and siRNA effectiveness has been found with the transfection of lipoplexes coated with 20% of Ceramide-PEG2000. This new nanovector could have a high potential against multiple mucosal diseases, such as human papillomavirus-induced genital lesions.

The siRNA cocktail targeting interleukin 10 receptor and transforming growth factor‐β receptor on dendritic cells potentiates tumour antigen‐specific CD8+ T cell immunity
In this study, we used small interfering RNA (siRNA) to silence the expression of endogenous molecules in DCs, which can sense immunosuppressive factors. Among the siRNAs targeting various immunosuppressive molecules, we observed that DCs transfected with siRNA targeting IL‐10 receptor alpha (siIL‐10RA) initiated the strongest antigen‐specific CD8+ T cell immune responses. The potency of siIL‐10RA was enhanced further by combining it with siRNA targeting TGF‐β receptor (siTGF‐βR), which was the next best option during the screening of this study, or the previously selected immunoadjuvant siRNA targeting phosp...

Effects of siRNA-mediated suppression of HPV-11 L1 expression on the proliferation and apoptosis of vaginal epithelial cells.
Authors: Zeng J, Yang S, Wang X, Gao Y, Zhang M
Abstract
The aim of the present study was to investigate the effects of human papillomavirus (HPV) infection on the gynecological disease of vaginitis and to demonstrate how the small interfering RNA (siRNA) method may be used for HPV prevention in the clinic. Human vaginal epithelial cells were transfected with HPV-11 L1 expression vector and siRNA-HPV-11 L1 vectors and a control group was transfected with scrambled siRNA. Cell proliferation in each group was analyzed using the MTT assay and the expression of apoptosis-associated proteins was measured by western blot...

Effect of HPV E6/E7 siRNA with Chemotherapeutic Agents on the Regulation of TP53/E2F Dynamic Behavior for Cell Fate Decisions.
Abstract
Toxicity and resistance remain major challenges for advanced or recurrent cervical cancer therapies, as treatment requires high doses of chemotherapeutic agents. Restoration of TP53 and hypophosphorylated-retinoblastoma (pRB) proteins by human papillomavirus (HPV) E6/E7 siRNA sensitizes HPV-positive cervical cancer cells toward chemotherapeutic agents. Here, we investigated the therapeutic effects of E6/E7 siRNA on the dynamic behavior of TP53 and RB/E2F signaling networks in deciding the cell fate. The synergistic effect of HPV E6/E7 siRNA pool (SP) with chemotherapeutic agents on TP53 and RB/E2F signali...

Robotic-assisted minimally invasive surgery for gynecologic and urologic oncology: an evidence-based analysis.
Authors: Health Quality Ontario
Abstract
OBJECTIVE: An application was received to review the evidence on the 'The Da Vinci Surgical System' for the treatment of gynecologic malignancies (e.g. endometrial and cervical cancers). Limitations to the current standard of care include the lack of trained physicians on minimally invasive surgery and limited access to minimally invasive surgery for patients. The potential benefits of 'The Da Vinci Surgical System' include improved technical manipulation and physician uptake leading to increased surgeries, and treatment and management of these cancers. The demand for roboti...

The Role of Pejorative Search Terms and Professional Antivaccine Advocates on Search Engine Results for Human Papillomavirus Vaccine
Fu et al. [1] highlighted important issues relating to the impact of page rankings and search terms on the quality of content that consumers access when seeking information about the human papillomavirus (HPV) vaccine. Of particular importance was recognition that previous articles only used neutral search terms. The authors, thus, utilized a methodology that incorporated non-neutral terms.

Thymoma-associated myasthenia gravis: On the search for a pathogen signature.
Abstract
Myasthenia gravis (MG) is an autoimmune disease mainly mediated by anti-acetylcholine receptor (AChR) antibodies. In the late onset, a thymoma, tumor of the thymus, is quite frequent. However, the events leading to thymoma and MG are not understood. As thymoma-associated MG (MG-T) patients also display anti-interferon type I (IFN-I) neutralizing antibodies, we investigated if MG-T could be associated with an anti-viral signature. RT-PCR analyses demonstrated huge increases of IFN-I subtypes, IFN-α2, -α8, -ω and -β, in thymoma-associated MG but not in thymomas without MG or in control thymuses. Next, w...

Inhibition of SMYD2 Sensitized Cisplatin to Resistant Cells in NSCLC Through Activating p53 Pathway
In conclusion, the present study elucidated that the activity of SMYD2 in NSCLC may affect the cell sensitivity to chemotherapeutic agents, especially to CDDP. The elevated SMYD2 mediated CDDP resistance and malignant phenotype in NSCLC, indicating that SMYD2 may be a useful biomarker of CDDP resistance in NSCLC. Inhibition of SMYD2 contributes to the methylation-related activation of p53 and thus results in cell apoptosis. Furthermore, combination treatment with CDDP and an SMYD2 inhibitor had a synergistically antitumor effects in a xenograft model in vivo. Given that SMYD2 has reversible effects and is a targetable prot...

Abstract 2115: Effect of small interfering RNA targeting HPV E6/E7 gene on the regulation of TP53/Rb dynamic behaviour in cervical cancer cells
Human papillomavirus (HPV) E6 and E7 viral oncogenes are very well known to cause cervical cancer, because E6 degrades TP53 tumor suppressor protein, and E7 inactivates the tumor suppressor retinoblastoma (pRb) protein. Thus E6 and E7 oncogenes of HPV are supposed to be promising targets of gene therapy against HPV mediated cervical cancer. Here, we attempted to study the regulation of TP53/pRb proteins dynamic behaviour after HPV E6/E7 small interfering RNA (siRNA) transfection in cervical cancer cells. HPV positive (HeLa and Caski) cell lines were selected for these experiments. Herein, we also validated the dynamics of ...
