Hypothesis
HPV16 E2 acts as a down-regulator in cellular genes involved in apoptosis, proliferation, and cell differentiation.
Conclusion
HPV16 E2 has regulatory effects on cellular gene expression in HPV negative cells, suggesting it creates a favorable environment for the virus's replicative cycle.
Supporting Evidence
- HPV16 E2 down-regulated 1048 genes and up-regulated 581 genes in C-33A cells.
- The WNT pathway was significantly affected, with 28 genes down-regulated and 15 up-regulated.
- Key genes involved in apoptosis and cell proliferation were altered by E2 expression.
Takeaway
The HPV16 E2 protein changes how cells behave by turning off many genes that help control cell growth and death, which might help the virus to replicate.
Methodology
The study used a recombinant adenoviral vector to express HPV16 E2 in C-33A cells and analyzed gene expression changes using microarrays.
