Objective: To evaluate the genital human papillomavirus (HPV) infection in patients from gynecology clinic, and to investigate the association of persistent HPV infection with cervical lesions.
Methods: From January, 2009 to December, 2013, clinical data of 16 320 patients in Third Xiangya Hospital were collected. A retrospective analysis was carried out to evaluate the overall prevalence of HPV infection. The prevalence of HPV infection in different ages and subtypes were compared. The prevalence of persistent HPV infection and results of cervical cytology were analyzed.
Results: The overall HPV prevalence was 26.54%. The lowest overall and high-risk HPV prevalence were found in women at the age of 30-39 years old (P<0.05); the highest ones were found at the age of over 60 years old, with significant difference among the aged groups (P<0.05). There was no significant difference in low-risk HPV prevalence among the aged groups (P=0.693). The clearance rate of HPV was 87.65% one year later. There was no significant difference in high-risk and low-risk HPV infection between the non-persistent positive group and the persistent positive group (P=0.545), but the difference in single and multiple subtypes infection between these 2 groups was significant (P<0.05). In the persistent positive group, the most common genotypes were HPV 16, 52, 58, CP8304, and 33. The incidence of ASC-US, HSIL or SCC was significantly increased in the persistent positive group.
Conclusion: Persistent HPV infection mainly consists of multiple and high-risk HPV infection. It is necessary to focus on the prevention of HPV 16, 52 and 58 persistent infection in our region.

Background: Oral cancer is a common head and neck cancer malignancy that seriously affects patients' quality of life and increases the health care burden. Moreover, there is a lack of comprehensive reviews of previous research on factors associated with oral cancer. The aim of the current umbrella review was to provide a comprehensive and systematic summary of relevant studies, to grade the quality of evidence of relevant studies, and to provide guidance for the prevention of oral cancer.

Different types of feline papillomaviruses (PVs) are associated with a variety of skin lesions and neoplasia, such as papillomas and cell carcinomas, but the virus can also be found in healthy skin. In this review, the European Advisory Board on Cat Diseases (ABCD), a scientifically independent board of veterinary experts on feline infectious diseases from 11 European Countries, discusses the current knowledge of feline PV infections. Cats most likely become infected through lesions or abrasions of the skin.

This study explores the effects of plant compounds on human papillomavirus (HPV)-induced W12 cervical precancer cells and bioelectric signaling. The aim is to identify effective phytochemicals, both individually and in combination, that can prevent and treat HPV infection and HPV associated cervical cancer. Phytochemicals were tested using growth inhibition, combination, gene expression, RT PCR, and molecular docking assays.

Human papillomavirus (HPV)-associated head and neck squamous cell carcinoma (HPV-positive HNSCC) has distinct biological characteristics from HPV-negative HNSCC. Using an AI-based analytical platform on meta cohorts, we profiled expression patterns of viral transcripts and HPV viral genome integration, and classified the tumor microenvironment (TME). Unsupervised clustering analysis revealed five distinct and novel TME subtypes across patients (immune-enriched, highly immune and B-cell enriched, fibrotic, immune-desert, and immune-enriched luminal).

The papillomavirus E2 protein regulates the transcription, replication, and segregation of viral episomes within the host cell. A multitude of post-translational modifications have been identified which control E2 functions. A highly conserved di-lysine motif within the transactivation domain (TAD) has been shown to regulate the normal functions of the E2 proteins of BPV-1, SfPV1, HPV-16, and HPV-31.
