Patents by Inventor Leland Hartwell

Leland Hartwell has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7122312
    Abstract: The present invention provides methods for identifying targets of a drug in a cell by comparing (i) the effects of the drug on a wild-type cell, (ii) the effects on a wild-type cell of modifications to a putative target of the drug, and (iii) the effects of the drug on a wild-type cell which has had the putative target modified of the drug. In various embodiments, the effects on the cell can be determined by measuring gene expression, protein abundances, protein activities, or a combination of such measurements. In various embodiments, modifications to a putative target in the cell can be made by modifications to the genes encoding the target, modification to abundances of RNAs encoding the target, modifications to abundances of target proteins, or modifications to activities of the target proteins. The present invention also provides methods for drug development based on the methods for identifying drug targets.

  • Publication number: 20050277149
    Abstract: The present invention relates to a method of identifying one or more secondary drug targets and their use in the identification of drug or drug candidates, particularly for the treatment of cancer. The yeast-based synthetic lethal screens were used to functionally identify and validate new gene targets to kill tumor cells with defects in cell cycle checkpoints and damage response pathways. These newly identified gene targets can be used to develop new cancer chemotherapeutics.
