For example, the histone deacetylase 9 (HDAC9) gene that displays lower relative expression in infected cells [20] was also expressed at a reduced level in TashAT2 transfected BoMac lines, as was the gene encoding synaptopodin 2 (SYNPO2), which induces focal adhesion [60] and can act as a tumour suppressor [61]. This evidence concerns the gene SYNPO2 and neoplasm.
