1. A method for predicting the responsiveness of a mammalian patient having a cancer to a chemotherapy regimen, comprising:
- predicting said mammalian patient (a) as responsive to said chemotherapy regimen, if expression and/or activity of one or more gene products in a cell sample taken from said mammalian patient is not up-regulated relative to a reference population of individuals of the same species as said mammalian patient;
or (b) as non-responsive to said chemotherapy regimen, if expression and/or activity of said one or more gene products is up-regulated relative to said reference population of individuals, wherein said one or more gene products comprise respectively products of one or more different genes selected from the group consisting of genes corresponding to SEQ ID NOs;
1-39 or respective functional equivalents thereof.

Abstract
The invention provides molecular markers that are associated with responsiveness of a cancer patient to a chemotherapy treatment, and methods and computer systems for determining such responsiveness based on measurements of these molecular markers. The present invention also provides methods and compositions for enhancing the efficacy of chemotherapies in patients by modulating the expression or activity of genes encoding these molecular markers and/or their encoded proteins.

-
72. A method of identifying an agent that is capable of modulating sensitivity of a cell to the growth inhibitory effect of a chemotherapeutic drug, said method comprising comparing a first growth inhibitory effect of said chemotherapeutic drug on cells expressing said gene in the presence of a candidate agent with a second growth inhibitory effect of said chemotherapeutic drug on cells expressing said gene in the absence of said agent, wherein said agent is capable of reducing the expression and/or activity of a gene selected from the group consisting of genes having SEQ ID NOs:
- 1-39 or respective functional equivalents thereof and/or its encoded protein, wherein a difference in said first inhibitory effect and said second growth inhibitory effect identities said agent as capable of modulating sensitivity of said cell to the growth inhibitory effect of said chemotherapeutic drug.
