CCNA2 and neoplasm: Secondly, RNA-sequencing (RNA-seq) analyses of cell-sorted, purified tumour-resident F4/80hi (both MHCIIhi and MHCIIlow) cells showed a clear upregulation of several cell cycle regulators, including cyclin-dependent kinase Cdk1, cyclin-A2 and -B2, E2f2, NEK family of serine/threonine kinases and various cell division cycle and mini-chromosome maintenance proteins family members, in comparison to their LP counterparts (Fig. 6b).
