The invention provides a high efficiency fluorescence in situ hybridization (FISH) method for detecting mutations on individual RNA transcripts, including both exonic and intronic RNA transcripts. In certain embodiments, the method is used to quantify allelic expression at the population and single cell level, and also to distinguish maternal chromosomes from paternal chromosomes in single cells.

Method for detecting mutations in single cells or single molecules

The present invention relates to systems and methods for measuring chromosome structure and gene expression. In one embodiment, the present invention includes an assay for determining the spatial organization of gene expression in the nucleus. The present invention also includes a method based on fluorescence in situ hybridization (FISH) that simultaneously yields information on the physical position and expression of individual genes. By lighting up a large number of targets on a particular chromosome using a bar-coding scheme, the large scale structure of an entire chromosome can be determined.

Method for detecting chromosome structure and gene expression simultaneously in single cells

In alternative embodiments, the invention provides compositions that inhibit the polypeptide SSH-2, or SlingSHot-2, a phosphatase enzyme that regulates actin filaments, and methods for making and using them, including methods comprising administering compositions of the invention to regulate or modify actin filament polymerization by inhibiting SSH-2, where in one embodiment compositions of the invention slow or inhibit F-actin depolymerization and severing. In alternative embodiments, compositions and methods of the invention are used to slow or inhibit cell motility and/or internal remodeling. In alternative embodiments, compositions and methods of the invention are used to slow or inhibit, or reverse, or ameliorate the progression of a cancer or a metastasis or other uncontrolled or unregulated cell growth, and/or Alzheimer's disease.
