Gene expression profiling reveals four distinct subgroups of multiple myeloma that have significant correlation with various clinical characteristics. Diagnosis for multiple myeloma (and possibly monoclonal gammopathy of undetermined significance) based on differential expression of 14 genes, as well as prognosis for the four subgroups of multiple myeloma based on the expression of 24 genes are established. A 15-gene model that classifies myeloma into 7 groups is also reported. Gene expression profiling also allows placing multiple myeloma into a developmental schema parallel to that of normal plasma cell differentiation. Development of a gene expression- or developmental stage-based classification system for multiple myeloma would lead to rational design of more accurate and sensitive diagnostics, prognostics and tumor-specific therapies for multiple myeloma.

Gene expression patterns were analyzed that identified multiple genes associated with radiation enhanced colon carcinogenesis. Some of the genes modulated by radiation exposure may be involved in up-regulating the Wnt/β-catenin signaling pathway and promote colon carcinogenesis. Consumption of a fish oil/pectin diet caused a general down-regulation of genes encoding proteins involved in cell adhesion and receptor activity, which may be involved in down-regulating the Wnt/β-catenin signaling pathway. The data suggest that dietary fish oil/pectin may be an effective countermeasure against radiation-induced colon carcinogenesis. In accordance with this, gene expression profiles can be monitored to reduce the risk of radiation induced carcinogenesis in high risk personnel (i.e., for example, astronauts) before, during, and/or after radiation exposure (i.e., for example, spaceflight), and/or to detect radiation-induced carcinogenesis so that an appropriate countermeasure administration can be implemented. The techniques are also targeted at non-invasively monitoring cancer patients after the primary cancer has been resected to determine if/when a secondary tumor develops.
