Methods for the diagnosis and treatment of lung cancer
View Patent ↗The present invention provides methods for aiding in the diagnoses of the neoplastic condition of a lung cell and methods of screening for a potential therapeutic agent for the reversal of the neoplastic condition.
1. A method for detecting and diagnosing lung cancer in a human patient, said method comprising:
(a) detecting the presence of an overexpressed b-mvb proto-oncogene in a lung cell sample taken from the patient; and
(b) determining that there is an indication of the presence of lung cancer in the patient when the proto-oncogene is overexpressed.
2. A method for identifying a human patient having lung cancer, said method comprising:
(a) determining the expression level of the b-myb proto-oncogene in a lung cell sample isolated from the patient; and
(b) identifying the patient as likely to have lung cancer when the expression level of the proto-oncogene in the sample is above the level of expression of the proto-oncogene in normal lung cells.
3. The method of claim 1 or 2 , further comprising:
(a) determining the expression level of the PGP9.5 proto-oncogene in a lung cell sample isolated from the patient; and
(b) determining that there is a further indication of the presence of lung cancer in the patient when the PGP9.5 proto-oncogene is overexpressed.
4. The method of claim 2 , wherein determining the expression level of the b-myb proto-oncogene comprises measuring the quantity of mRNA transcribed from the b-myb proto-oncogene in the sample.
5. The method of claim 2 , wherein determining the expression level of the b-myb proto-oncogene comprises measuring the quantity of cDNA produced from the reverse transcription of the b-myb mRNA in the sample.
6. The method of claim 2 , wherein determining the expression level of the b-myb proto-oncogene comprises measuring the quantity of the polypeptide or protein encoded by the b-myb proto-oncogene in the sample.
7. The method of claim 1 or 2 , wherein the lung cancer is non-small cell lung cancer.
8. The method of claim 2 , wherein determining the expression level of the b-myb proto-oncogene comprises probing the lung cell sample with a probe or primer comprising the sequence TGCTGCCCTG (SEQ. ID No. 1) or its complement.
9. The method of claim 1 , wherein detecting the presence of an overexpressed b-mvb proto-oncogene in a lung cell sample taken from the patient comprises measuring the quantity of mRNA transcribed from the b-myb proto-oncogene in the sample.
10. The method of claim 1 , wherein detecting the presence of an overexpressed b-mvb proto-oncogene in a lung cell sample taken from the patient comprises measuring the quantity of mRNA transcribed from the b-myb proto-oncogene in the sample.
11. The method of claim 1 , wherein detecting the presence of an overexpressed b-mvb proto-oncogene in a lung cell sample taken from the patient comprises measuring the quantity of cDNA produced from the reverse transcription of the b-myb mRNA in the sample.
12. The method of claim 1 , wherein detecting the presence of an overexpressed b-mvb proto-oncogene in a lung cell sample taken from the patient comprises measuring the quantity of the polypeptide or protein encoded by the b-myb proto-oncogene in the sample.
13. The method of claim 1 , wherein detecting the presence of an overexpressed b-mvb proto-oncogene in a lung cell sample taken from the patient comprises probing the lung cell sample with a probe or primer comprising the sequence TGCTGCCCTG (SEQ. ID No. 1) or its complement.
