A gene family is a set of homologous genes within one organism. A gene cluster is part of a gene family. A gene cluster is a group of two or more genes found within an organism's DNA that encode for similar polypeptides, or proteins, which collectively share a generalized function and are often located within a few thousand base pairs of each other. The size of gene clusters can vary significantly, from a few genes to several hundred genes. Portions of the DNA sequence of each gene within a gene cluster are found to be identical; however, the resulting protein of each gene is distinctive from the resulting protein of another gene within the cluster. Genes found in a gene cluster may be observed near one another on the same chromosome or on different, but homologous chromosomes. An example of a gene cluster is the Hox gene, which is made up of eight genes and is part of the Homeobox gene family.

The present invention is generally directed to the evolution of new metabolic pathways and the enhancement of bioprocessing through a process herein termed recursive sequence recombination. Recursive sequence recombination entails performing iterative cycles of recombination and screening or selection to “evolve” individual genes, whole plasmids or viruses, multigene clusters, or even whole genomes. Such techniques do not require the extensive analysis and computation required by conventional methods for metabolic engineering.

A method for associating a gene with a trait exhibited by one or more organisms in a plurality of organisms from a species. A genetic marker map is constructed from a set of genetic markers associated with the plurality of organisms. For each gene in a plurality of genes, a quantitative trait locus analysis is performed using the genetic marker map and a quantitative trait. The quantitative trait locus analysis produces quantitative trait locus data. A quantitative trait comprises an expression statistic for a gene. The expression statistic for a gene is derived from a cellular constituent level that corresponds to the gene in each organism in the plurality of organisms. The quantitative trait locus data are clustered from each quantitative trait locus analysis to form a quantitative trait locus interaction map. Clusters of genes in the map are identified as a candidate pathway group. An expression cluster map is used to refine the candidate pathway group. Multivariate analysis is used to validate the candidate pathway group as a set of genes that are genetically interacting.

Methods for the detection and treatment of cancer
InactiveUS20070231822A1Raise the possibilityMicrobiological testing/measurementDiseaseLymphatic Spread
Methods are provided for the detection of and determining prognosis of metastatic breast, lung, prostate, and / or pancreatic cancer using various genetic markers, including markers for gene clusters linked by Esx. In one method, breast cancer micrometastases and non-small cell lung cancer metastases or micrometastases are detected in a patient by determining whether the AGR2 or TFF1 genes are overexpressed in a cell sample compared to control lymph node tissue cells. In a further method, the likelihood that a patient diagnosed with breast cancer will respond to hormonal therapy is predicted by determining a higher expression level of the AGR2 gene compared to a control gene. In a further method, a decreased probability of survival for a patient diagnosed with early stage non-small cell lung cancer is predicted by determining a higher expression level of the AGR2 gene compared to a control gene. Kits for practicing the methods of the invention are further provided. Methods are also provided for the identification of markers for which overexpression is indicative of the presence of micrometastatic disease.
