Abstract: Described herein are methods and composition for diagnosing and evaluating the treatment of depression using one or more biomarker metabolites for the diagnosis and monitoring treatment efficacy. In one aspect, the biomarker metabolites can be used to screen subjects for the likelihood of developing depression, the diagnosis thereof, monitoring the efficacy of treatment, and evaluating a subject's propensity for responding to treatment.

Abstract: This document provides methods and materials for treating cancer (e.g., estrogen receptor positive breast cancer). For example, methods and materials for identifying a mammal (e.g., a human) with cancer (e.g., estrogen receptor positive breast cancer) as having A?G variant genotype of rs6990851 and/or as having an elevated level of CSMD1 nucleic acid expression and administering one or more aromatase inhibitors (e.g., anastrozole) to treat the mammal identified as having such genotype and/or elevated level are provided.

Abstract: This document provides methods and materials involved in assessing chemotherapy responsiveness and treating cancer (e.g., breast cancer). For example, methods and materials for determining whether or not a cancer patient (e.g., a breast cancer patient) is likely to respond to chemotherapy (e.g., a taxane therapy) based at least in part on the presence of a variant in the mammal's polycystic kidney disease gene 1 (PKD1) are provided. In addition, methods and materials involved in treating mammals having cancer (e.g., breast cancer) by administering an inhibitor of ubiquitin specific peptidase 2 (USP2) polypeptide activity (e.g., NSC-632839, a 2-cyano-pyrimidine, or a 2-cyano-triazine) in combination with another chemotherapeutic agent such as a taxane therapy are provided.

Abstract: The present invention concerns the application of lipidomics to statin treatment for disorders such as cardiovascular disorders. Hence, the invention provides, among other things, a method of correlating a lipid profile with a positive or negative response to a statin treatment regimen by obtaining a lipid profile of a sample from a mammalian subject following commencement of the treatment regimen; and correlating the lipid profile in the sample with a positive or negative response to the treatment regimen. The invention further provides a method of correlating a lipid profile with a positive or negative response to a statin treatment regimen by obtaining a lipid profile of a sample from a mammalian subject before commencement of the treatment regimen; and correlating the lipid profile in the sample with a positive or negative response to the treatment regimen.
