Herrero and colleagues show that in a phase III randomized trial in Guanacaste, Costa Rica, the use of a human papillomavirus type 16 (HPV16) and HPV18 ASO4-adjuvanted vaccine (Cervarix) resulted in complete efficacy against 12-month persistent HPV16 and HPV18 infections and partial protection against HPV31, 33, and 45 in HPV-naïve young women ages 18 to 25.
OBJECTIVES To evaluate the clinicopathologic correlation and prognostic value of HPV18 DNA viral load in patients with early-stage cervical neuroendocrine carcinoma (NECA). METHODS Formalin-fixed, paraffin- embedded tissue of cervical NECA patients with known HPV18 infection and clinicopathologic data including follow-up results were collected. The HPV18 DNA load was assessed with quantitativ...
Infection with oncogenic human papillomavirus (HPV) is considered to be the major risk factor for cervical cancer. Tumor necrosis factor (TNF) is a pluripotent cytokine that plays an important role in inhibiting the action of microbial agents, and TNF microsatellite polymorphisms have been associated with several diseases, including cancer and viral infections. This study analyzed the associati...
abstract background and aims: cervical cancer is among leading causes of cancer related death in women and human papilloma virus (hpv) is one of the important risk factor of this cancer. the aim of the present study was to develop a pcr method for identification of a high carcinogenic type of hpv, hpv 18 using e6 gene as a marker in patients with cervical cancer materials and methods: 92 formal...
Background: Various studies proposed virus infection is to be a possible cause of human breast cancer. However, the data argue the association between virus and cancer are inconsistent. This study was conducted to detect whether HPV-DNA is present in tissue samples of breast cancer in Isfahan province. Materials and Methods: Paraffin embedded formalin fixed specimens were prepared from 40 brea...
The expression of the high risk HPV18 E6 and E7 oncogenic proteins induces the transformation of epithelial cells, through the disruption of p53 and Rb function. The binding of cellular transcription factors to cis-regulatory elements in the viral Upstream Regulatory Region (URR) stimulates E6/E7 transcription. Here, we demonstrate that the CCAAT-transcription factor NF-Y binds to a non-canonic...
Cervical carcinoma cells producing high levels of interleukin-6 (IL-6) were shown to be unresponsive to the cytokine IL-6 due to the loss of their IL-6 receptor. Addition of IL-6 receptor in a soluble form restores IL-6 signalling in SW756 carcinoma cells. This leads to a rapid and strong activation of the transcription factor signal transducer and activator of transcription 3 (STAT3). Nuclear ...
The distributions of human papillomavirus (HPV) types detected in cervical adenocarcinomas and squamous cell tumors differ. However, whether the distributions of intratypic HPV variants seen in these two histological forms of cervical disease differ is unknown. Our objective was to compare the distribution of HPV intratypic variants observed in squamous cell carcinomas (SCC) and cervical tumors...
BACKGROUND Several assays are used to measure type-specific serological responses to human papillomavirus (HPV), including the bead-based glutathione S-transferase (GST)-L1 multiplex serology assay and virus-like particle (VLP)-based ELISA. We evaluated the high-throughput GST-L1, which is increasingly used in epidemiologic research, as a measure of cumulative HPV infection and future immune pr...
