Viral cyclins can play a significant role in the development of cancer by disrupting normal cell cycle regulation. By overriding the cell's natural control mechanisms, viral cyclins can cause uncontrolled cell division, leading to the formation of tumors. This is particularly evident in certain oncoviruses like Human Papillomavirus (HPV) and Epstein-Barr Virus (EBV), which are known to encode viral cyclins.
