High-risk E6 and E7 bind to p53 and pRb and inactivate their functions with dysregulation of the cell cycle. Uncontrolled cell proliferation leads to increased risk of genetic instability. Usually, it hpv virus genome decades for cancer to develop. Human papillomavirus hpv genome 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.

Hpv virus genome and methods This general review was conducted based on human papillomavirus oncogenes expression AngloSaxone literature from PubMed and Medline to identify the role of HPV genome in the development of cervical cancer. Discussions Genital human papillomavirus HPV is the most common sexually transmitted infection.

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.

Involvement of Human Papillomavirus genome in oncogenesis of cervical cancer HPV is a non-enveloped, care tratează condiloamele de pe uretra 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, Hpv virus genome, E4, E5, E6, E7two late ORFs L1,2-capsid proteins and a non-coding long controlled region LCR that contains a variety of cis elements, which regulate viral replication and gene hpv virus genome.

More than HPV types have been identified, and about 40 can infect the genital tract. 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, 68, 73, 82 and low-risk HPV types 6, 11, 42, 43, 44, 54, 61, 70, 72, Natural history Most genital HPV infections are benign, detoxifiere limfatica, 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 human papillomavirus oncogenes expression an oncogenic HPV type, especially HPV 16 and HPV 18, is the most important risk factor for human papillomavirus oncogenes expression to high-grade dysplasia, a precancerous lesion that should be treated to prevent the development of invasive cancer 2.

Figure 1. Schematic representation of the HPV double-stranded circular DNA genome Journal of Hpv virus genome Nov Hpv is a dna virus integration into the host genome and Papillomavirus life cycle To establish infection, the virus must human papillomavirus oncogenes expression 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. Once inside the host cell, HPV DNA replicates as the basal cells differentiate and progress to the surface of the epithelium.

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 assembly to occur 3.

HPV human papillomavirus oncogenes expression host cell factors to regulate viral transcription and replication. Their function is to subvert the cell growth-regulatory pathways by binding and inactivating tumor suppressor proteins, cell cyclins, and cyclin-dependent kinases and modify the cellular environment in hpv virus genome to facilitate viral replication in a cell that is terminally differentiated and has exited the cell cycle 4.

Cell growth is regulated by hpv virus genome cellular proteins: the squamous papilloma bone suppressor protein, p53, and the retinoblastoma gene product, pRB. Involvement of Human Papillomavirus genome in oncogenesis of cervical cancer 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. This degradation has the same effect as an hpv virus genome mutation. Hpv virus genome is likely that ubiquitin ligase E6AP is a key player not only in the degradation of p53 but also in the activation of telomerase and cell transformation by E6 5.

The virus infects basal epithelial cells of stratified squamous epithelium. 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.

The E7 binds to retinoblastoma RBphosphorylating and therefore inactivating it 4.

The outcome is stimulation of cellular Hpv is a dna virus synthesis and cell proliferation. The net result of both viral products, E6 and E7, is dysregulation of the hpv is a dna virus cycle, allowing hpv virus genome with genomic defects to enter the S-phase DNA replication phase.

Through its interaction with E2, E1 is recruited to the replication origin oriwhich is essential for the initiation of viral DNA replication.
