The Burnham Institute - La Jolla CA

International Classification:

A61K 3170

US Classification:

514 44, 4353201, 435455, 435456, 435458

Abstract:

The present invention provides mammalian retinoblastoma (Rb) protein-interacting zinc finger (RIZ) proteins, nucleic acid molecules encoding the RIZ and antibodies specific for the RIZ. The invention also provides screening assays for identifying an agent that effectively alters the association of a RIZ with a second molecule, which can bind to the RIZ. The invention also provides active fragments of RIZ containing the PR domain, which can regulate transcription. In addition, the invention provides methods for introducing a nucleic acid molecule-encoding a RIZ into a cell and for A-contacting a cell with an effective agent in order to modulate a function of a cell. Such methods are useful, for example, for inducing growth of a cardiac cell or a neuronal cell in a subject and for effecting normal growth control to a tumor cell or causing differentiation of tumor cells. The invention further provides methods for detecting a RIZ in a sample by detecting the RIZ or a nucleic acid molecule encoding the RIZ. Such methods are useful to diagnose a pathology that is characterized by an increased or decreased level of a RIZ in a cell or by expression of a mutant RIZ in a cell.

International Classification:

C07H021/04
C12Q001/68

US Classification:

435 6, 435 911, 435 912, 536 231, 536 243

Abstract:

The invention provides a method of inhibiting growth of a microsatellite instability (MSI)-positive tumor. The method is practiced by introducing into an MSI-positive tumor a nucleic acid molecule encoding a RIZ1 polypeptide and expressing the RIZ1 polypeptide in the tumor in an effective amount to inhibit growth of the tumor. Also provided is a method of determining the MSI status of a tumor. The method is practiced by determining in the tumor the number of adenosine (A) nucleotides in a poly(A) tract of a RIZ nucleic acid molecule in the tumor. An abnormal number of adenosine nucleotides in a RIZ poly(A) tract indicates that the tumor is MSI-positive.

US Classification:

435 15, 435193, 530327

Abstract:

The invention provides a method of screening for a compound that modulates RIZ histone methyltransferase (HMT) activity, by contacting a RIZ or RIZ fragment having HMT activity with one or more candidate compounds, and determining histone methyltransferase activity of the contacted RIZ or RIZ fragment. Also provided is a method of screening for a compound that modulates progesterone receptor (PR) activity, by providing a RIZ1 modulatory compound, and determining the ability of the RIZ1 modulatory compound to modulate PR activity. Further provided is a method of identifying an individual with an estrogen receptor positive (ER+) tumor having a reduced likelihood of responding to endocrine therapy. The method involves determining the RIZ1 status of the tumor, wherein an abnormal RIZ1 status identifies the individual as an individual with a reduced likelihood of responding to endocrine therapy.
