Effect of Vif in doxorubicin treated breast cancer cells
Introduction Several studies linked DNA cytosine deaminase APOBEC3 to mutational process driving carcinogenesis [1]. However, APOBEC3 expression varies in breast cancer cells [2] and their role in breast cancer treatment remains elusive.

APOBEC3 genes: retroviral restriction factors to cancer drivers [PDF]
The APOBEC3 cytosine deaminases play key roles in innate immunity through their ability to mutagenize viral DNA and restrict viral replication. Recent advances in cancer genomics, together with biochemical characterization of the APOBEC3 enzymes, have now implicated at least two family members in somatic mutagenesis during tumor development.

Feline APOBEC3s, Barriers to Cross-Species Transmission of FIV?
The replication of lentiviruses highly depends on host cellular factors, which defines their species-specific tropism. Cellular restriction factors that can inhibit lentiviral replication were recently identified.

The APOBEC3 Family of Retroelement Restriction Factors [PDF]
The ability to regulate and even target mutagenesis is an extremely valuable cellular asset. Enzyme-catalyzed DNA cytosine deamination is a molecular strategy employed by vertebrates to promote antibody diversity and defend against foreign nucleic acids.

Antiretroviral APOBEC3 cytidine deaminases alter HIV-1 provirus integration site profiles
Antiretroviral APOBEC3 may contribute to HIV-1 latency. In this study, Ajoge and Renner et al. identify a previously undescribed function of human APOBEC3 proteins in redirecting integrations of HIV-1 DNA into more transcriptionally inactive regions of ...

Structural Insights into APOBEC3-Mediated Lentiviral Restriction
Mammals have developed clever adaptive and innate immune defense mechanisms to protect against invading bacterial and viral pathogens. Human innate immunity is continuously evolving to expand the repertoire of restriction factors and one such family of intrinsic restriction factors is the APOBEC3 (A3) family of cytidine deaminases.

Role of co-expressed APOBEC3F and APOBEC3G in inducing HIV-1 drug resistance
The APOBEC3 enzymes can induce mutagenesis of HIV-1 proviral DNA through the deamination of cytosine. HIV-1 overcomes this restriction through the viral protein Vif that induces APOBEC3 proteasomal degradation.

APOBEC3D and APOBEC3F potently promote HIV-1 diversification and evolution in humanized mouse model. [PDF]
Several APOBEC3 proteins, particularly APOBEC3D, APOBEC3F, and APOBEC3G, induce G-to-A hypermutations in HIV-1 genome, and abrogate viral replication in experimental systems, but their relative contributions to controlling viral replication and viral ...

Codon pairs of the HIV-1 vif gene correlate with CD4+T cell count [PDF]
Background: the human APOBEC3G (A3G) protein activity is associated with innate immunity against HIV-1 by inducing high rates of guanosines to adenosines (G-to-A) mutations (viz., hypermutation) in the viral DNA. If hypermutation is not enough to disrupt
