CDK8 and adenoma: Another more recent study using the heterozygous germline Apcmin mutant model of intestinal tumourigenesis also concluded that Cdk8 deletion does not hinder tumourigenesis; on the contrary, in this model, while there was no difference in micro‐adenoma formation, detectable increases in tumour number, size, and fraction of proliferating cells were observed upon deletion of Cdk8 (McCleland et al, 2015).
