A computer-assisted method of looking for pharmacologic targets, in which large numbers of persons are enrolled in drugh clinical trials, they are medically examined and documented, tissue samples are taken, the tissue samples are genotyped, and an examination is made of the genotypes to try to ascertain associations between the genotypes and the documented disease phenotypes of the patients.

Genetically elite ungulate mammals are identified on the basis of gene expression profiles from biological samples such as liver and blood. Methods and compositions are presented to select genetically elite animals with a desired phenotype such as high milk production for breeding to improve production levels. A method to select an animal with a specific phenotype, e.g. milk production and health traits, includes creating a Gene Expression Index for a specific phenotype and using the index to identify candidate animals for breeding by comparing the index to gene expression profiles of the animals.

An embodiment of the present invention is a method for measuring activity of cell pathways, such as the cell cycle pathway and correlating the resulting profile to phenotypes. The resulting correlations are useful in diagnosis, prognosis, selection and development of drug treatment regimens, and drug screening applications.

The present invention relates to novel double-stranded RNA (dsRNA) structures and dsRNA expression constructs, methods for generating them, and methods of utilizing them for silencing genes. Desirably, these methods specifically inhibit the expression of one or more target genes in a cell of animal (e.g., a mammal such as a human) without inducing toxicity. These methods can be used to prevent or treat a disease or infection by silencing a gene associated with the disease or infection. The invention also provides method for identifying nucleic acid sequences that modulate a detectable phenotype, such as the function of a cell, the expression of a gene, or the biological activity of a target polypeptide.

Polynucleotide delivery-enhancing polypeptides are admixed or complexed with, or conjugated to, nucleic acids for enhancing delivery the nucleic acids into cells. The transported nucleic acids are active in target cells as small inhibitory nucleic acids (siNAs) that modulate expression of target genes, mediated at least in part by RNA interference (RNAi). The siNA/polypeptide compositions and methods of the invention provide effective tools to modulate gene expression and alter phenotype in mammalian cells, including by altering phenotype in a manner that eliminates disease symptoms or alters disease potential in targeted cells or subject individuals to which the siNA/polypeptide compositions are administered.

A method of generating cells capable of secreting insulin is disclosed. The method comprises subjecting mammalian embryonic stem cells to set of culturing conditions suitable for differentiation of at least a portion thereof into cells displaying at least one characteristic associated with a pancreatic islet cell progenitor phenotype, and subjecting such differentiated cells to a set of culturing conditions suitable for formation of surface bound cell clusters including insulin producing cells.

The present invention relates to infectious DNA clones, infectious chimeric DNA clones of porcine circovirus (PCV), vaccines and means of protecting pigs against viral infection or postweaning multisystemic wasting syndrome (PMWS) caused by PCV2. The new chimeric infectious DNA clone and its derived, avirulent chimeric virus are constructed from the nonpathogenic PCV1 in which the immunogenic ORF gene of the pathogenic PCV2 replaces a gene of the nonpathogenic PCV1, preferably in the same position. The chimeric virus advantageously retains the nonpathogenic phenotype of PCV1 but elicits specific immune responses against the pathogenic PCV2. The invention further embraces the immunogenic polypeptide expression products.

The present invention is directed to plants that display a drought tolerance phenotype due to altered expression of a DR03 nucleic acid. The invention is further directed to methods of generating plants with a drought tolerance phenotype.

This invention provides methods for monitoring QTL effects and marker assisted selection (MAS) involving providing a recursively determined correlation between one or more markers and a phenotype of interest.

A method for reversing expression of malignant phenotype in cancer cells is described. The method comprises applying beta 1 integrin function-blocking antibody to the cells. The method can be used to assess the progress of cancer therapy. Human breast epithelial cells were shown to be particularly responsive.

Isolated polynucleotides and polypeptides encoded thereby are described, together with the use of those products for making transgenic plants.

The present invention provides a variety of nucleic acid based therapeutics and methods of use thereof which are effective to beneficially reprogram diseased cells such that they exhibit more desirable phenotypes. Also provided are compositions and methods to reprogram normal cells for medical and commercial purposes.

The present invention provides methods of marker assisted selection for high oleic/low linolenic traits in canola and in other oil seed crop species, as well as isolated nucleic acids for use as molecular markers in such methods. In particular, molecular markers and Brassica nucleic acid corresponding to fad2 and fad3 gene mutations are disclosed. The markers of the present invention are highly useful for the direct selection of desirable fad2 and fad3 alleles during marker-assisted trait introgression and breeding. In a one aspect of the embodiment, two single nucleotide polymorphism (SNP) markers are provided which correspond to the alleles. Thus, the present invention advantageously permits one of skill in the art to breed for the molecular markers described herein, or derivatives thereof, rather than breeding for a high oleic/low linolenic phenotype.

The present invention provides methods and systems for automated morphological analysis of cells. The inventive methods are particularly useful in the rapid analysis of cells required in a biological screen. Agents which cause a particular phenotype in the cells can be identified using the inventive quantitative morphometric analysis of cells. The data gathered using the inventive method can also be quantified and analyzed later for various trends and classifications. Characteristics of cells which can be determined using this method include number of nuclei, size of cell, size of nuclei, number of the centrosomes, shape of cells, size of centrosomes, perimeter of nucleus, shape of nucleus, pattern of staining, and degree of staining.

The present invention provides a method for expanding a population of chondrocytes that maintains chondrocyte phenotype during the expansion by culturing the population in a defined serum-free expansion medium containing one or more cytokines and under low attachment conditions. The method further solves diffusion problems during the subsequent stage of extracellular matrix production by use of a perforated polycarbonate substrate that results in a randomly organized cultured neocartilage tissue. Chondrocytes expanded and cultured in this manner can be used in various medical applications to repair cartilaginous tissues that have been injured by trauma or disease.

The present invention, in one aspect, relates to a method for examining a target for tumors or lesions using what is referred to as “Early Increase in microvascular Blood Supply” (EIBS) that exists in tissues that are close to, but are not themselves, the abnormal tissue and in tissues that precede the development of such lesions or tumors. While the abnormal tissue can be a lesion or tumor, the abnormal tissue can also be tissue that precedes formation of a lesion or tumor, such as a precancerous adenoma, aberrant crypt foci, tissues that precede the development of dysplastic lesions that themselves do not yet exhibit dysplastic phenotype, and tissues in the vicinity of these lesions or pre-dysplastic tissues.

Rice having reduced levels of starch branching enzymes produce grain having a high relative amylose content in the endosperm. The rice grain of this invention can be of a non-shrunken phenotype despite a lesion in the amylopectin synthesis pathway and may be transgenic or nontransgenic.
