Abstract
Methods of-identifying a basal or luminal phenotype of a cell, comprising detecting expression of one or more of a set of predictive biomarker genes or proteins that identify the cell as having a basal or luminal cancer subtype and compositions for treating identified basal or luminal cancers.

14. A method for identifying a basal-type cancer patient, comprising:
- (a) measuring expression level of one gene selected from the group consisting of genes encoding SCNN1A, CA12, PRKX, TFF3, HNF3A, MYB, GABRP, ESR1, AGR2, GATA3, FOXC1, and EN1, in a sample from the patient; and
(b) comparing the expression level of the gene from the patient with expression level of the gene in a normal tissue sample or a reference expression level, wherein an increase of expression of one gene selected from the group consisting of the genes encoding PRKX, GABRP, FOXC1, and EN1 and a decrease of expression of one gene selected from the group consisting of the genes encoding SCNN1A, CA12, TFF3, HNF3A, MYB, ESR1, AGR2, and GATA3 indicates the patient has basal-type cancer. - View Dependent Claims (15, 16, 17)

18. A method for identifying a basal or luminal phenotype of a cell, comprising:
- (a) measuring expression level of one gene selected from the group consisting of genes encoding SCNN1A, CA12, PRKX, TFF3, HNF3A, MYB, GABRP, ESR1, AGR2, GATA3, FOXC1, and EN1, in a patient sample; and
(b) comparing the expression level of gene from a sample with expression level of the gene in a normal tissue sample or a reference expression level, wherein an increase of expression in the patient sample of one gene selected from the group consisting of the genes encoding PRKX, GABRP, FOXC1, and EN1, indicates the cell has a basal phenotype and an increase of expression of one gene selected from the group consisting of the genes encoding SCNN1A, CA12, TFF3, HNF3A, MYB, ESR1, AGR2, and GATA3, indicates the cell has a luminal phenotype. - View Dependent Claims (19)

33. An assay to detect modulated expression of a gene as a predictor or marker of basal-type cancers, the assay comprising:
RT-PCR primers dimensioned and configured to detect transcription level of one or more genes selected from the group consisting of SCNN1A, CA12, PRKX, TFF3, HNF3A, MYB, GABRP, ESR1, AGR2, GATA3, FOXC1, and EN1.
-
34. An assay to detect modulated expression of a gene as a predictor or marker of basal-type cancers, the assay comprising immunochemical reagents to detect a polypeptide expressed by one or more genes selected from the group consisting of SCNN1A, CA12, PRKX, TFF3, HNF3A, MYB, GABRP, ESR1, AGR2, GATA3, FOXC1, and EN1.
- 35. A compound to treat a cell that exhibits modulated expression of a gene that is a predictor or maker of basal-type cancer, wherein the compound is configured to inhibit expression of one or more genes selected from the group consisting of SCNN1A, CA12, PRKX, TFF3, HNF3A, MYB, GABRP, ESR1, AGR2, GATA3, FOXC1, and EN1.
