Improving the Understanding of Pathogenesis of Human Papillomavirus 16 via Mapping Protein-Protein Interaction Network

Abstract EN

The human papillomavirus 16 (HPV16) has high risk to lead various cancers and afflictions, especially, the cervical cancer.

Therefore, investigating the pathogenesis of HPV16 is very important for public health.

Protein-protein interaction (PPI) network between HPV16 and human was used as a measure to improve our understanding of its pathogenesis.

By adopting sequence and topological features, a support vector machine (SVM) model was built to predict new interactions between HPV16 and human proteins.

All interactions were comprehensively investigated and analyzed.

The analysis indicated that HPV16 enlarged its scope of influence by interacting with human proteins as much as possible.

These interactions alter a broad array of cell cycle progression.

Furthermore, not only was HPV16 highly prone to interact with hub proteins and bottleneck proteins, but also it could effectively affect a breadth of signaling pathways.

In addition, we found that the HPV16 evolved into high carcinogenicity on the condition that its own reproduction had been ensured.

Meanwhile, this work will contribute to providing potential new targets for antiviral therapeutics and help experimental research in the future.
