Inhibition of the Akt kinase activates HPV16 late gene expression by reducing HPV16 early polyadenylation and by activating HPV16 late L1 mRNA splicing. We identified 'hot spots' for RNA binding proteins at the early polyA signal and at splice sites on HPV16 late mRNAs. We observed that hnRNP L was associated with sequences at all HPV16 late splice sites and at the early polyA signal. Akt kinas...
Persistent high-risk human papillomavirus (HPV) infection is a pivotal factor in the progression of cervical cancer. In recent years, an increasing interest has emerged comprehending influence HPV on head and neck squamous cell carcinoma (HNSCC). Notably, it well established that HPV-associated HNSCC show cases with distinct molecular clinical attributes compared to HPV-negative cases. The pres...
Although HPV16 transforms infected epithelial tissues to cancer in the presence of several co-factors, there is insufficient molecular evidence that poor nutrition has any such role. Because physiological folate deficiency led to the intracellular homocysteinylation of heterogeneous nuclear ribonucleoprotein E1 (hnRNP-E1) and activated a nutrition-sensitive (homocysteine-responsive) posttranscr...
Introduction: Human papillomavirus (HPV) is the main causative agent of cervical cancer worldwide leading to a big health problem, especially in the developing countries. Among 14 common high-risk genotypes, HPV16 accounts for more than 50% of all cervical cancers. The current prophylactic vaccines against HPV infection are based on L1 protein. Due to some drawbacks in the current vaccines such...
BACKGROUND Recent evidence has accumulated suggesting that human papillomavirus (HPV) plays a role in the development of head and neck squamous cell carcinoma (HNSCC). HPV16 is the most common of the HPV subtypes associated with oral and laryngeal malignancies. This study estimated the prevalence of HPV16 DNA in Puerto Rican patients with HNSCC. METHODS DNA was extracted from frozen tissue of...
HPV16 variants correlate with geographic origin and ethnicity. The association between infection with a specific variant and the cervical disease risk remains unclear. We studied the prevalence, persistence and association with cervical intraepithelial neoplasia (CIN) of different HPV16 variants, using cervical swabs and whole tissue sections (WTS) of biopsies from 548 women in the placebo grou...
BACKGROUND The increasing incidence of oropharyngeal cancer in many developed countries has been attributed to human papillomavirus type 16 (HPV16) infections. Recently, HPV16 E6 serology has been identified as a promising early marker for oropharyngeal cancer. Therefore, characterization of HPV16 E6 seropositivity among individuals without cancer is warranted. METHODS A total of 4,666 contro...
Background. Breast cancer remains the leading cause of cancer-related mortality worldwide. It has been indicated that human papillomaviruses 16 (HPV16) might participate in the pathogenesis and development of breast cancer. However, the detected rate of HPV16 varies with region. We will investigate HPV16 E6 expression in North China and explore the effects and mechanism of HPV16 E6 on breast ca...
PURPOSE Squamous cell carcinomas of the head and neck (HNSCC) often harbor p53 mutations, but p53 protein degradation by the viral oncoprotein E6 may supercede p53 mutations in human papillomavirus 16 (HPV16)-positive tumors. The prevalence of p53 mutations in HPV-positive HNSCCs is indeed lower, but in some tumors these alterations coexist. The purpose of this study was to discern whether HNSC...
BACKGROUND Studies suggest that testing for individual human papillomavirus (HPV) genotypes can improve risk stratification in women with minor cytologic abnormalities. We evaluated genotyping for HPV16, HPV16/18, and HPV16/18/45 in carcinogenic HPV-positive women with atypical squamous cells of undetermined significance (ASCUS) and low-grade squamous intraepithelial lesion (LSIL) cytology. M...
