Increased expression of CDK6 in other primary tumors such as in squamous cell carcinoma [44,45], basal cell carcinoma [46], medulloblastoma, and B-cell lymphoproliferative disorder [47] have been reported in which increased CDK6 expression has been correlated with induced cell proliferation and malignant transformation coupled with cyclins. The gene discussed is CDK6; the disease is medulloblastoma.
