Abstract

Anoikis is known as a special type of programmed cell death which occurs in response to loss of correct cell-extracellular matrix (ECM) connections. This process could be as pivotal event in normal development and tissue homeostasis and found as important mechanism in cancer invasiveness and metastasis. The persistent infection with oncoviruses including EBV (Epstein Bar virus), HPV (Human Papillomaviruses), HBV (Hepatitis B virus), KSHV (Human herpesvirus 8), HTLV-1 (Human T-lymphotropic virus-1), and HCV (Hepatitis C virus) accounted as one of main risk factor for cancer progression. Some of them play critical roles in metastasis, especially in anoikis resistance which could contribute to metastasis of tumor cells. The better understanding of effects of oncoviruses on anoikis could contribute to finding of effective therapeutic platforms for treatment of virus-associated cancers. This paper highlighted effects of these oncoviruses on anoikis protection in cancer.
