An explorative gene expression analysis for EGR3, cFOS, BUB1, MXD1, JUNB, cJUN, ETV5 and DUSP1 - genes known to be regulated by ERK1/217 - as well as for - CDKN1B, CDKN1A, GADD45, BCL6, CCNG2, CCNB1, CAT, SOD2 and PLK1 - genes known to be regulated by AKT18–20 was performed in our lymphoma cohort. The gene discussed is PLK1; the disease is lymphoma.
