Conditional ERK3 overexpression cooperates with PTEN deletion to promote lung adenocarcinoma formation in mice.

ABSTRACT: ERK3, officially known as mitogen-activated protein kinase 6 (MAPK6), is a poorly studied mitogen-activated protein kinase (MAPK). Recent studies have revealed the upregulation of ERK3 expression in cancer and suggest an important role for ERK3 in promoting cancer cell growth and invasion in some cancers, in particular lung cancer. However, it is unknown whether ERK3 plays a role in spontaneous tumorigenesis in vivo. To determine the role of ERK3 in lung tumorigenesis, we created a conditional ERK3 transgenic mouse line in which ERK3 transgene expression is controlled by Cre recombinase. By crossing these transgenic mice with a mouse line harboring a lung tissue-specific Cre recombinase transgene driven by a club cell secretory protein gene promoter (CCSP-iCre), we have found that conditio
