Firstly, we performed Immunoprecipitation (IP) experiments using antibodies of MED13L, representative members of the core Mediator (the head module: MED6 and MED8; the middle module: MED1 and MED4; the tail module: MED23) and three components of the CDK8 kinase module (MED12, CCNC and CDK8) in NSCLC cells. Here, MED23 is linked to non-small cell lung carcinoma.
