Objective:
To investigate the role of CDK2 in the development of DNA heteroploid in laryngeal squamous cell carcinoma (LSCC).
Method:
Fifty specimens of LSCC, twelve specimens of atypical hyperplasia and thirty specimens of vocal cord polyp were obtain during operation. Centrosome were detected by anti tubulin antibodies. Immunohistochemical method was used to analyze the protein expression of CDK2 and gamma-tubulin.
Result:
The positive rate of CDK2 and gamma-tubulin in LSCC were 68.0% (34/50) and 78.0% (10/15), all of them were significant higher than those in the vocal cord polyp (P<0.05). Expression of CDK2 in LSCC was positively association with expression of gamma-tubulin.
Conclusion:
This experiment indicated that overexpression of CDK2 was strongly correlated with abnormal proliferation in LSCC, and it may be a valuable marker for the diagnosis and therapy of LSCC.

M-Cdk Drives Transition Into Mitosis
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.

Two states at the origin of replication
In eukaryotes, the initiation of replication occurs at many sites on the chromosomes, called the origins of replication.
