HPV E6 and E7 oncoproteins are the critical molecules in the process of malignant tumour formation. Interacting with various cellular proteins, E6 and E7 influence fundamental cellular functions like cell cycle regulation, telomere maintenance, susceptibility to apoptosis, intercellular adhesion and regulation of immune responses. High-risk E6 and E7 bind to p53 and pRb and inactivate their functions with dysregulation of the cell cycle.
In addition to tobacco and alcohol abuse, certain viruses have been associated with squamous cell carcinoma SCC of the head and neck, causing alterations in DNA.
Uncontrolled cell proliferation leads to increased risk of genetic instability. Usually, it takes decades for papillomavirus known as hpv to develop. This review presents the main mechanisms of HPV genome in the carcinogenesis of the uterine cervix. Virusul infectează epiteliile bazale, celule de epiteliu scuamos stratificat.

Proteinele celulare E6 și E7 influențează fundamental funcțiile celulare, cum ar fi reglarea ciclului celular, întreținerea telomerilor, susceptibilitatea la apoptoză, adeziunea intercelulară și reglarea răspunsurilor imune. E6 și E7 cu grad ridicat de risc se leagă la p53 și PRB și inactivează funcțiile lor cu papillomavirus known as hpv ciclului celular.
Proliferarea necontrolată a celulelor conduce la un risc crescut de instabilitate genetică. De obicei, este nevoie de zeci de ani pentru a dezvolta un cancer. Acest review prezintă principalele mecanisme ale genomului HPV în carcinogeneza colului uterin.

- The role of human papillomavirus infection in the pathogenesis of the external and the middle ear squamous papilloma and squamous cell carcinoma.
The most important papillomavirus known as hpv factor in the ethiology of cervical cancer is the persistent infection with a high-risk strain of human papillomavirus. Materials and methods This general review was conducted based on the AngloSaxone literature from PubMed and Medline to identify the role of HPV genome in the development of cervical cancer.
Although the majority of infections cause no symptoms and are self-limited, persistent infection with high-risk types of HPV is the most important risk factor for cervical cancer precursors and invasive cervical cancer.
The presence of HPV in They are also responsible for others genital neoplasias like vaginal, vulvar, anal, and penian. HPV is a non-enveloped, double-stranded DNA virus from the family of Papillomaviridae, with an 8 kb circular genome composed of six early ORFs open reading frames with role in viral transcription and replication E1, E2, E4, E5, E6, E7two late ORFs L1,2-capsid proteins and papillomavirus known as hpv non-coding long controlled region LCR that contains a variety of cis elements, which regulate viral replication and gene expression.

Based on their association with cervical cancer and precursor lesions, HPVs are grouped to high-risk 16, 18, 31, 33, 34, 35, 39, 45, 51, 52, 56, 58, 59, 66, papillomavirus known as hpv, 73, 82 and low-risk HPV types 6, 11, 42, 43, 44, 54, 61, 70, 72, Natural history Most genital HPV papilloma virus squamous cell are papilloma virus squamous cell, subclinical, and self-limited, and a high proportion of infections associated with low-grade cervical dysplasias also regress spontaneously 1.
By contrast, persistent cervical infection infection detected more than once in an interval of 6 months or longer with an oncogenic HPV type, especially Papillomavirus known as hpv 16 and HPV 18, is the most important risk factor for progression to high-grade dysplasia, a precancerous lesion that should be treated papilloma virus squamous cell prevent the development of invasive cancer 2.

HPV is a necessary but not a sufficient condition for the development of cervical cancer. Cofactors associated with cervical cancer include: cigarette smoking, increased parity, increased age, other sexually transmitted infections, immune suppression, long-term oral contraceptive use, and other host factors.
Figure 1. Schematic representation of the HPV double-stranded circular DNA genome Journal of Virology Nov HPV integration into the host genome and Papillomavirus life cycle To establish infection, the virus must infect basal epithelial cells of stratified squamous epithelium, that are long lived or have stem cell-like properties.
Microtrauma of the suprabasal epidermal cells enables the virus to infect the cell within the basal layer.
Viruses Can Cause HPV Related Cancers
Once inside the host cell, HPV DNA replicates as the basal cells differentiate and progress to the surface of the epithelium. The viral genome maintains itself as an episome in basal cells, where the viral genes are poorly expressed. In the differentiated keratinocytes of the suprabasal layers of the epithelium, the virus switches to a rolling-circle mode of DNA replication, amplifies its DNA to high copy number, synthesizes capsid proteins, and causes viral papillomavirus known as hpv to occur 3.

HPV papilloma virus squamous cell host cell factors to regulate viral transcription and replication. Their function is to subvert the cell growth-regulatory pathways by binding papilloma virus squamous cell inactivating tumor suppressor proteins, cell cyclins, and cyclin-dependent kinases and modify the cellular environment in order to facilitate viral replication in a cell that is terminally differentiated and has exited the cell cycle 4.
Unlike in many other cancers, the p53 in cervical cancer is usually wild type and is not mutated. E6 binds to p53 via a cellular ubiquitin ligase named E6AP, so that it becomes ubiquitinated, leading to degradation and down-regulation of pathways involved in cycle arrest and apoptosis.
