It is estimated that up to 20% of all types of human cancers worldwide are attributed to viruses. The genome of oncogenic viruses carries genes that have protein products that act as oncoproteins in cell proliferation and transformation. The modulation of cell cycle control mechanisms, cellular regulatory and signaling pathways by oncogenic viruses, plays an important role in viral carcinogenes...

background globally, almost 20% of cancers are related to infectious agents that can be prevented. oncogenicity refers to viruses that may cause cancers, more importantly in immunocompromised subjects such as transplant and hemodialysis patients. therefore, epidemiological studies are the first line for understanding the importance of these agents in public health, particularly, in mobile popul...

Oncogenic viruses are the viruses that cause cancers in their natural hosts or experimental animal systems which are thought to be causative agents of about 15-20% of cancers. They have been broadly classified into the DNA oncogenic viruses and RNA oncogenic viruses based on the nature of the nucleic acid contain within their virion. The oncogenic DNA and RNA viruses that have been identified b...
