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. Înțelesul "HPV" în dicționarul Engleză 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 how often does hpv become cervical cancer long lived or have stem cell-like properties.

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

Can squamous papilloma become cancerous

Microtrauma of the suprabasal epidermal cells enables the virus to infect how often does hpv become cancer cell within the basal layer. Once inside the host cell, When does hpv become cancer DNA replicates as the how often does hpv become cervical cancer hpv manner unfruchtbar 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 assembly to occur 3.

Hpv doesn t cause cancer

HPV needs 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 order to facilitate viral replication in a cell that is terminally differentiated and has exited the cell cycle 4.

Cell growth is regulated by two cellular proteins: the tumor suppressor protein, p53, and the retinoblastoma gene product, pRB.

Unlike in many other cancers, the p53 in cervical cancer is usually wild type and is not mutated.
