摘要:
A two-step, scalable method is described for identifying the cellular function(s) of one or more genes of unknown function, and for identifying modulators of the gene(s). The method uses the reversal or alteration of a phenotype created by the expression of the heterologous gene, e.g., a human gene, to identify modulators of that gene's activity. That modulator is then used in an in vitro or in vivo disease model system to identify compounds which affect disease progression. The subset of compounds which influence disease in a therapeutic manner are drug leads. However, all compounds which influence disease progression are tools to at least partially characterize gene function. The inhibitor identification step of the method is preferably carried out using a plurality of microbial strains or cell lines expressing different heterologous DNA sequences in a single solution. The method is particularly useful for genes which have not been validated as good inhibitor targets.

The invention provides systems and methods for remote computer-based analysis of user provided chemogenomic data. The invention includes computer-based systems and software that allow a remote user to access a centralized comprehensive chemogenomic database and use the correlative tools of that database to assess the user's data. The tools allow the user to generate a summary report of the chemogenomic/toxicogenomic analysis results obtained using the chemogenomic database.
摘要:
The invention provides methods for preparing reagent sets based on small subsets of highly informative genes capable of carrying out a broad range of chemogenomic classification tasks. The invention also provides high-throughput diagnostic assays and devices based on these reduced subsets of information rich genes. In addition, the invention provides a general method for selecting a reduced subset of highly responsive variables from a much larger multivariate dataset, and thus, use of these variables to prepare diagnostic measurement devices, or other analytic tools, with little or no loss of performance relative to devices or tools incorporating the full set of variables.

The invention discloses reagent sets and gene signatures for predicting onset of renal tubule injury in a subject. The invention also provides a necessary set of 186 genes useful for generating signatures of varying size and performance capable of predicting onset of renal tubule injury. The invention also provides methods, apparatuses and reagents useful for predicting future renal tubule injury based on expression levels of genes in the signatures. In one particular embodiment the invention provides a method for predict whether a compound will induce renal tubule injury using gene expression data from sub-acute treatments.
摘要:
The present invention provides methods and compositions for producing high titer preparations of recombinant AAV (“rAAV”) virions. The compositions of the present invention include AAV helper function systems and host cells. The present invention also includes methods of using AAV helper function vectors that effect the production of only small amounts of the long forms of Rep protein, and rAAV virions produced by such methods.

Disclosed is a method for predicting the biological activity of a compound by the similarity of its drug signature score to the scores of a plurality of known drug signatures.
摘要:
The present invention discloses methods of data analysis directed to diagnostic development, and in particular the development of signatures for classifying chemogenomic data. The invention provides methods for identifying and functionally characterizing a “necessary” set of information rich variables. The invention also discloses methods for identifying a plurality of “sufficient” classifiers. The necessary set of variables may be incorporated into a single diagnostic device to provide simultaneous confirmation of a classification measurement with a plurality of independent classifiers. In the field of biological diagnostics, the invention may be used to provide a plurality of short lists of genes, referred to as “signatures” that are “sufficient” to carry out specific classification tasks such as predicting the activity and side effects of a compound in vivo.
