Abstract: A CDK profile including a ratio of specific activities of two cyclin dependent kinases closely correlates with the malignancy grade and the presence/absence of the sensitivity to an irritant such as an anticancer agent of a cancer tissue in clinical medicine. Therefore, the properties of a mammalian cell, such as malignancy grade, proliferation potency, sensitivity to an irritant such as an anticancer agent can be assessed based on its CDK profile or by comparing the result of a specific activity ratio of two CDKs with a predetermined threshold corresponding to the ratio. This sensitivity assessing method shows a high ratio of correct assessing results particularly in positive or sensitivity and is useful in predicting efficacy of chemotherapy using the anticancer agent.

Abstract: A method of supporting a diagnosis of an effect of a treatment by using anthracycline anticancer drugs is disclosed. The method provides a new value for judging an effect, a judgment score, which is calculated based on expression levels and activity values of two cyclin dependent kinases (CDKs).

The judging step comprises judging the feature of the malignant tumor based on the comparison results of the first comparing step and the second comparing step.

Abstract: The present invention provides a method for determining the chemosensitivity of a cancer cell to a taxane comprising assessing the effect of the taxane on the expression level or activity of one or more cell cycle molecules in a cancer cell. Such a method makes use of an automated analyzer system wherein cell cycle parameters (molecules) such as CDK1 kinase activity, CDK1 expression, CDK2 kinase activity, CDK2 expression, MAD2 expression, Cyclin B1, Cyclin E expression, p21 expression, and CDK6 expression; are assessed. The present invention further provides a method of obtaining a cell cycle profile of a cancer cell that is sensitive to a taxane.

Abstract: A method of supporting a diagnosis of a risk of cancer recurrence is disclosed. The method provides a new determining value a recurrence risk score (RRS) which is calculated based on expression levels and activity values of two cyclin dependent kinases (CDKs). The risk of cancer recurrence is judged by comparing the RRS with a predetermined threshold level for RRS.

Abstract: A method for predicting an effectiveness of chemotherapy is described. The method comprises a comparing step and a predicting step. The comparing step is a step of comparing a threshold value with a parameter of a cyclin dependent kinase (CDK) included in a sample containing a tumor cell obtained from a human patient. The predicting step is a step of predicting the effectiveness based on a comparison result of the comparing step. Above stated parameter is selected from the group consisting of an activity, an expression level, and a ratio of activity to expression level.

Abstract: The present invention provides a method for predicting an effectiveness of chemotherapy using an anticancer agent with high probability. The effectiveness is predicted based on a comparison of a parameter relating to CDK and/or CDK inhibitor in a tumor cell specimen obtained from a patient, with a corresponding threshold value to the parameter. The patient to be subjected this sensitivity prediction test of an anticancer agent is administered with the anticancer agent prior to removal of the tumor cell. The threshold is predetermined based on data of correlation between the selected parameter and anticancer agent therapy results obtained from a number of patients actually performed the therapy. Accordingly, the predicting method can provide information useful for determining whether to perform the chemotherapy to individual patients.

Abstract: A method of measuring the activity of a kinase to which imatinib mesylate can bind is described. In the method, a kinase contained in a sample, to which imatinib mesylate can bind, a substrate for the kinase, and ATP are mixed. A phosphate group of ATP is thereby transferred to a tyrosine residue of the substrate by the action of the kinase. After a labeled substance capable of binding is bound to the substrate having the phosphate group transferred thereto, a signal emitted by the labeled substance is detected. On the basis of this detection result, the activity of the kinase is calculated.
