1. A method of monitoring a gene expression profile associated with oral cancer comprising:
- contacting a first array of probes with a first population of nucleic acids derived from a human subject from one or more cells obtained from malignant oral tissue;
contacting a second array of probes with a second population of nucleic acids derived from the human subject from one or more cells obtained from normal oral tissue; and
determining relative hybridization of the first array of probes to the first population of nucleic acids relative to hybridization of the second array of probes to the second population of nucleic acids, wherein at least one nucleic acid that hybridizes differently is encoded by a gene of a gene expression profile that is associated with oral cancer, wherein the gene of the gene expression profile is selected from the group consisting of p-53 responsive gene 2, beta A inhibin, human alpha-1 collagen type I gene, placental protein 11, BENE protein, neuromedin U, flavin containing monooxygenase 2, runt-related transcription factor 1, alpha 2 collagen type I, fibrillin 1, absent in melanoma 1, nonvoltage-gated 1 alpha sodium channel, protein tyrosine kinase 6 and epithelial membrane protein 1.

2. A method of expression monitoring comprising:
-
contacting a first array of probes with a first population of nucleic acids derived from at least one cell derived from normal oral tissue from a human subject; contacting a second array of probes with a second population of nucleic acids derived from at least one cell derived from malignant oral tissue from the human subject; and determining binding of the first array of probes to the nucleic acids from the first population relative to binding of the second array of probes to the nucleic acids from the second population to identify at least one probe binding to a nucleic acid that is differentially expressed between the first and second populations, wherein the nucleic acid is encoded by a gene selected from the group consisting of p-53 responsive gene 2, beta A inhibin, human alpha-1 collagen type I gene, placental protein 11, BENE protein, neuromedin U, flavin containing monooxygenase 2, runt-related transcription factor 1, alpha 2 collagen type I, fibrillin 1, absent in melanoma 1, nonvoltage-gated 1 alpha sodium channel, protein tyrosine kinase 6 and epithelial membrane protein 1.

3. A method of diagnosing a human subject with oral cancer, the method comprising:
-
detecting a level of expression of a marker selected from a group of markers associated with oral cancer in a test sample from the human subject; and detecting the level of expression of the marker in a control sample from normal tissue from the human subject, wherein the level of expression of the marker in the control sample differs from the level of expression of the marker in the test sample when the subject is afflicted with oral cancer, and wherein the marker is encoded by a gene selected from p-53 responsive gene 2, beta A inhibin, human alpha-1 collagen type I gene, placental protein 11, BENE protein, neuromedin U, flavin containing monooxygenase 2, runt-related transcription factor 1, alpha 2 collagen type I, fibrillin 1, absent in melanoma 1, nonvoltage-gated 1 alpha sodium channel, protein tyrosine kinase 6 and epithelial membrane protein 1. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 19)

15. A method for monitoring the progression of oral cancer in a human subject, the method comprising:
-
detecting in a first sample obtained from the human subject at a first point in time, a level of expression of a marker selected from a group of markers associated with oral cancer; detecting in a subsequent sample obtained from the human subject at a subsequent point in time, the level of expression of the marker, and comparing the level of expression detected in the first and subsequent detecting samples in order to monitor the progression of oral cancer, wherein the marker is encoded by a gene selected from p-53 responsive gene 2, beta A inhibin, human alpha-1 collagen type I gene, placental protein 11, BENE protein, neuromedin U, flavin containing monooxygenase 2, runt-related transcription factor 1, alpha 2 collagen type I, fibrillin 1, absent in melanoma 1, nonvoltage-gated 1 alpha sodium channel, protein tyrosine kinase 6 and epithelial membrane protein 1. - View Dependent Claims (16, 17, 18)
