Detecting Bcl-B expression in cancer and uses thereof
View Patent ↗Provided herein are compositions and methods of detecting Bcl-B expression in cancer cells to prognose, monitor, or select therapies for cancers such as breast cancer, prostate cancer, lung cancer, or gastric cancer.
1. A method of selecting a therapy for treating a subject with breast cancer or prostate cancer, comprising examining the expression of Bcl-B in one or more cells of said cancer, wherein a higher amount of Bcl-B expression in the cancer cells or a higher number or percentage of cancer cells with detectable Bcl-B expression as compared to that of non-metastatic reference cells indicates that the selected treatment is adjuvant chemotherapy or hormonal therapy, wherein a lower or equivalent amount of Bcl-B expression in the cancer cells or a lower or equivalent number or percentage of cancer cells with detectable Bcl-B expression as compared to that of non-metastatic reference cells indicates that the selected treatment is surgery, local therapy, or a combination thereof.
2. The method of claim 1 , wherein the reference cells comprise healthy cells from the same tissue of the subject as the cancer cells.
3. The method of claim 1 , wherein the reference cells comprise non-cancerous cells of same tissue from the subject.
4. The method of claim 1 , wherein the reference cells comprise non-cancerous cells of same tissue from one or more unrelated individuals.
5. The method of claim 1 , wherein the reference cells comprise non-cancerous cells from the same tissue of the subject as the cancer cells.
6. A method of selecting a therapy for treating a subject with lung cancer, comprising examining the expression of Bcl-B in one or more cells of said cancer, wherein a higher amount of Bcl-B expression in the cancer cells or a higher number or percentage of cancer cells with detectable Bcl-B expression as compared to that of non-metastatic reference cells indicates that the selected treatment is aggressive chemotherapy, investigational drugs, or a combination thereof.
7. The method of claim 6 , wherein the reference cells comprise healthy cells from the same tissue of the subject as the cancer cells.
8. The method of claim 6 , wherein the reference cells comprise non-cancerous cells of same tissue from the subject.
9. The method of claim 6 , wherein the reference cells comprise non-cancerous cells of same tissue from one or more unrelated individuals.
