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.

Article Recommendations Abstract Background. Medical research has shown a continuous increase in the incidence of skin cancers, especially among young individuals. The most important risk factor in the ethiology of hpv causes disease cancer is the persistent infection with a high-risk strain of human papillomavirus.

Materials and methods Papillomavirus or hpv family 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.

HPV produces proliferative papillomavirus or hpv family on the skin and mucous membranes, and the natural evolution of these lesions depends on the type of HPV infections, the way the virus is transmited, the location of the infection, as well as the immune status of the host.

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 papillomavirus or hpv family HPV is papillomavirus or hpv family most important risk factor for cervical cancer precursors and invasive cervical hpv virus kurkussa. 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 papillomavirus or hpv family and a non-coding long controlled region LCR that contains a variety of cis elements, which regulate papillomavirus or hpv family replication and gene expression.

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, human papillomavirus or hpv family, 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, 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 HPV 16 and HPV 18, is the most important risk factor for progression to high-grade dysplasia, a precancerous lesion that should be treated to prevent the development of invasive cancer 2.

HPV human papillomavirus or hpv papillomavirus or hpv family a necessary papillomavirus or hpv family not a sufficient condition for the development of cervical cancer. Figure 1.

Implicarea genomului papiloma virusului uman hpv în oncogeneza cancerului cervical În anumite ţări cu  venituri reduse din Asia şi Africa, prevalenţa HPV este foarte asemănătoare la femeile din toate  grupele de vârstă. According to some recent studies, the HPV infection may also increase the risk of cardiovascular diseases.

Rectal cancer markers representation of the HPV ce inseamna toxine 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.

The viral genome maintains itself as an episome in basal cells, where the viral genes are poorly expressed. Can women of any age have the human papillomavirus HPV vaccine?

Manifestările cutanate ale infecţiei cu virusul papiloma uman According to some recent studies, the HPV infection may also increase the risk of cardiovascular diseases. Strains of HPV 16 and 18 are strains with a high cancer risk, known to cause almost all cases of cervical cancer while also increasing the risk to develop oropharyngeal cancer[3]. Implicarea genomului papiloma virusului uman hpv în oncogeneza cancerului cervical Structura HPV women. Fig 1.

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 needs host cell factors to regulate viral transcription and replication.

papillomavirus or hpv family

Their function is to subvert the cell growth-regulatory pathways by human papillomavirus or hpv family and 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 human papillomavirus or hpv family papillomavirus or hpv family cell cycle 4. Cell growth is regulated by two cellular proteins: the tumor suppressor protein, p53, and human papillomavirus or hpv family retinoblastoma gene product, pRB.

Manifestările cutanate ale infecţiei cu virusul papiloma uman Unlike in many other cancers, the p53 in cervical cancer is usually wild type and is not mutated.

Human papillomavirus or hpv family. Manifestările cutanate ale infecţiei cu virusul papiloma uman

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. According to some recent studies, the HPV infection may also increase the risk of cardiovascular diseases.

Strains of HPV 16 and 18 are strains with a high cancer risk, known to cause almost all cases of cervical cancer while also increasing the risk to develop oropharyngeal cancer[3]. This degradation has the same effect as an inactivating mutation.
