Diagnosis and treatment of cancer
View Patent ↗The invention is based on the elucidation of a mechanism by which HPV promotes oncogenesis and provides a methods of diagnosing malignant tumors and methods of preventing the development of malignancies or inhibiting tumor growth. A method for diagnosing a neoplasm in a mammal is carried out by measuring the level of helicase-like transcription factor (HLTF) in tissue of the mammal. An increase in the level of HLTF in the tissue compared to the level in a normal control tissue indicates the presence of a neoplasm in the tissue.
1. A method for diagnosing a breast neoplasm in a mammal, comprising measuring the level of helicase-like transcription factor (HLTF) in breast tissue of said mammal, wherein an increase in the level of HLTF in said tissue compared to the level in non-cancerous breast indicates the presence of a breast neoplasm in said tissue, wherein said measuring step comprises detecting a HLTF transcript in said tissue and wherein said transcript encodes the amino acid sequence of SEQ ID NO: 10.
2. A method for detecting the presence of a malignant breast tumor or a predisposition to developing said tumor, comprising contacting a sample of nucleic acid molecules obtained from a breast tissue biopsy with a nucleic acid probe which hybridizes under stringent conditions to a human HLTF nucleic acid transcript, wherein the transcript encodes the amino acid sequence of SEQ ID NO: 10, and determining the level of binding of said probe, wherein an increase in said binding compared to that in non-cancerous breast indicates the presence of a malignant breast tumor or a predisposition to developing said tumor, wherein said stringent conditions comprise a wash condition at 650° C. and a salt concentration of 0.1×SSC and wherein said probe comprises at least 15 nucleotides of SEQ ID NO: 9.
3. The method of claim 2 , wherein said probe comprises at least 30 nucleotides of SEQ ID NO:9.
4. The method of claim 2 , wherein said probe comprises at least 50 nucleotides of SEQ ID NO:9.
5. The method of claim 2 , wherein said probe comprises at least 100 nucleotides of SEQ ID NO:9.
6. The method of claim 2 , wherein said probe comprises at least 250 nucleotides of SEQ ID NO:9.
7. The method of claim 2 , wherein said probe comprises at least 500 nucleotides of SEQ ID NO:9.
