When cyclin B levels are elevated, cells can enter M phase prematurely and strict control over cell division is lost, which is favorable for cancer development.
Cyclin B is a regulatory protein that plays a crucial role in cell cycle progression, particularly in the transition from the G2 phase to mitosis. Its expression levels can significantly impact cancer progression and patient prognosis.
Cyclin B expression is often elevated in various cancers and is generally associated with poor prognosis.
Cyclin B levels:
-Accumulate during S and G2
-Peak at mitotic entry
-Are rapidly destroyed at metaphase–anaphase transition via the APC/C ubiquitin ligase
