Abstract:
In order to define more effective predictive markers for clinical management and prognosis, we evaluated the expression of cyclin D1 and survivin in large papillary thyroid carcinoma (LPTC) and microcarcinoma (PTM). Sixty-seven patients operated for papillary carcinoma (36 of which with PTM) were considered. Immunochemistry for cyclin D1 and survivin was performed in samples from tumor mass and nodal metastases. There were not significant differences between LPTC and PTM as to patients personal data, TNM or MACIS staging, nodal invasion and multifocality, while capsular invasion was significantly more frequent in LPTC. Cyclin D1 and survivin were expressed at a very high rate and almost to the same extent in LPTC and PTM, both in tumoral mass and in nodal metastases. Survivin showed only cytoplasmic expression. Cyclin D1 and survivin over-expression are probably early events in tumorigenesis of thyroid papillary carcinoma but their full role in the process of tumor progression and their clinical value are still to be investigated.

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.
