Cell Cycle Markers

The cell cycle is a series of processes, including cell proliferation, that a cell undergoes during its life cycle. Cancer lesions commonly originate from aberrant cellular proliferation.

Abnormal cellular proliferation can be caused by mutations or amplifications in the open-reading frames or regulatory domains of oncogenes and tumor suppressors that regulate cell growth.

Cell Cycle Regulation

Cell cycle progression is positively regulated and enforced by a family of serine/threonine protein kinases collectively referred to as cyclin-dependent kinases (CDKs). CDKs are activated by binding to respective cyclin partners and by phosphorylation.

These checkpoint pathways recognize and sense whether or not to initiate and/or promote cellular proliferation under a particular set of external and internal conditions. Crucial components of these pathways are mainly proteins encoded by some checkpoint genes including the tumor suppressor protein p53.
