[A]: no

[Q]: Question: Does Np63 enhance the oncogenic phenotype of osteosarcoma cells by inducing the expression of GLI2?
Answer: Here, we report that GLI2 is the novel target gene of Np63 and that Np63-GLI2 crosstalk in osteosarcoma cells is a necessary event in osteosarcoma progression. Defining the exact mechanisms involved in this interaction that mediate the pathogenesis of osteosarcoma promises to identify targets for drug therapy.
[A]: yes
