Abstract:
Among the DNA tumor viruses Epstein-Barr virus (EBV) and Kaposi sarcoma herpesvirus (KSHV), account for a considerable percentage of virus-associated cancers. Deregulation of transcription factors signaling pathways is one of the most significant oncogenic characteristics of EBV and KSHV. NF-κB is a transcription factor that play a remarkable role in oncogenesis because of its function as a master regulator of a spectrum of genes involved in physiological and pathophysiological process. Constitutive activation of NF-κB is a frequent and well-described event in many human malignancies. Compelling evidence represent EBV and KSHV are capable of targeting different components of NF-κB cascade. Here, we summarized recent findings to clarify the precise relationship between dysregulation of NF-κB and EBV and KSHV-related malignancies. This essay also emphasizes on contribution of various viral products in developing cancer through alteration of NF-κB signaling pathway.
Insights
Epstein-Barr virus (EBV) and Kaposi sarcoma herpesvirus (KSHV) can cause cancer by disrupting the NF-κB signaling pathway. Understanding this link is key to developing new cancer therapies.
Area of Science:
- Oncology
- Virology
- Molecular Biology
Background:
- Epstein-Barr virus (EBV) and Kaposi sarcoma herpesvirus (KSHV) are DNA tumor viruses linked to significant cancer burdens.
- Dysregulation of transcription factor signaling pathways is a key oncogenic feature of EBV and KSHV infections.
Purpose of the Study:
- To clarify the relationship between NF-κB signaling pathway dysregulation and EBV/KSHV-related malignancies.
- To highlight the role of viral products in cancer development via NF-κB pathway alteration.
Main Methods:
- Literature review of recent findings on EBV, KSHV, and NF-κB signaling.
- Analysis of the mechanisms by which these viruses target the NF-κB cascade.
Main Results:
- Constitutive activation of NF-κB is common in human cancers.
- Both EBV and KSHV are shown to target various components of the NF-κB signaling pathway.
- Viral products contribute to oncogenesis by altering NF-κB signaling.
Conclusions:
- Dysregulation of the NF-κB pathway is a critical factor in EBV and KSHV-associated cancers.
- Targeting viral interference with NF-κB signaling may offer therapeutic strategies for virus-driven malignancies.
