Title:	Coiled coil helix cristae morphology 1 (CHCM1) tumor marker and cancer therapeutic target
Abstract:	Methods for diagnosing and treating a cancer or a tumor in a patient are provided. The methods can comprise the steps of obtaining a biological sample from the patient and analyzing the sample for the presence or absence of Coiled Coil Helix Cristae Morphology 1 protein (CHCM1). A patient is diagnosed with cancer or a tumor provided that CHCM1 is overexpressed. The diagnosed patient is treated by administering a cancer or tumor treatment. The methods can also comprise the steps of obtaining a sample of cancer or tumor cells from the patient, determining a level of CHCM1 expression in the sample of cancer or tumor cells, and administering to the patient a compound for reducing the expression of CHCM1 or for blocking or inhibiting function of CHCM1.

The method of claim 1, wherein determining the level of CHCM1 protein or CHCM1 nucleic acid comprises performing an assay, wherein the assay is immunohistochemical staining, Western blotting, immunoprecipitation, protein pull-down, Northern or dot blotting, or a microarray procedure, or a modification thereof on the sample, wherein the assay comprises using an antibody specific for a CHCM1 protein, using a nucleic acid that binds to a CHCM1 nucleic acid, or using a peptide that binds to a CHCM1 protein, and wherein the assay detects CHCM1 expression. 4. The method of claim 3, wherein determining the level of CHCM1 nucleic acid comprises detecting a level of mRNA for CHCM1 in the sample. 5. A method for treating a patient being administered vemurafenib comprising: obtaining a biological sample from the patient being administered vemurafenib; determining a level of Coiled Coil Helix Cristae Morphology 1 (CHCM1) protein or nucleic acid expression in the biological sample; and provided that the biological sample expresses at least a 1.5-fold higher level of CHCM1 than matching normal tissue, administering to the patient a genotoxic anti-cancer compound for reducing the expression of CHCM1, for blocking or inhibiting function of CHCM1, or for blocking or inhibiting CHCM1 interactions with other proteins. 6. The method of claim 5, wherein the patient exhibits resistance to vemurafenib. 7. A method for diagnosing and treating a cancer or a tumor in a patient, wherein the cancer or the tumor harbors a vemurafenib-sensitive BRAF mutation comprising: obtaining a biological sample from a patient; determining a level of Coiled Coil Helix Cristae Morphology 1 (CHCM1) protein or CHCM1 nucleic acid in the sample; testing the biological sample for presence of a vemurafenib-sensitive BRAF mutation; and provided that the biological sample tests positive for presence of a vemurafenib-sensitive BRAF mutation, and provided that the sample expresses at least a 1.5-fold higher level of CHCM1 protein or CHCM1 nucleic acid than a level of CHCM1 protein or CHCM1 nucleic acid in matching normal tissue, administering vemurafenib and a genotoxic anti-cancer compound to the patient, wherein the genotoxic anti-cancer compound reduces the expression of CHCM1, blocks or inhibits function of CHCM1, or blocks or inhibits CHCM1 interactions with other proteins. 8. The method of claim 7, wherein the vemurafenib-sensitive BRAF mutation is a V600 BRAF mutation. 9. A method for diagnosing and treating a cancer or a tumor expressing a vemurafenib-insensitive BRAF mutation or a BRAF wild-type gene in a patient comprising: obtaining a biological sample from a patient; determining a level of Coiled Coil Helix Cristae Morphology 1 (CHCM1) protein or nucleic acid in the sample; testing the sample for presence of a vemurafenib-sensitive BRAF mutation or a wild-type BRAF gene; and provided that the sample tests negative for presence of the vemurafenib-sensitive BRAF mutation or tests positive for the wild-type BRAF gene, and provided that the biological sample expresses at least a 1.5-fold higher level of CHCM1 protein or CHCM1 nucleic acid than a level of CHCM1 protein or CHCM1 nucleic acid in matching normal tissue, administering to the patient a genotoxic anti-cancer compound for reducing expression of CHCM1, for blocking or inhibiting function of CHCM1, or for blocking or inhibiting CHCM1 interactions with other proteins. 10.
