Antagonists of Products of the HS.459642 Unigene Cluster for the Inhibition of Proliferation, Development or Differentiation of Stem Cells Including Cancer Stem Cells
The present disclosure provides methods and compositions for inhibiting the proliferation, differentiation, or development of stem cells and cancer stem cells in a patient in need thereof. The methods involve administering to a patient a therapeutically effective amount of an antagonist of an Hs.459642 Unigene Cluster product, such as an inhibitor of CACNA1H. The compositions include an antagonist of an Hs.459642 Unigene Cluster product, such as an inhibitor of CACNA1H. Specific antagonists such as antibodies and antisense oligonucleotides, and combination therapy with one or more additional anti-cancer agents, are also provided by this disclosure. Such methods, antagonists, and compositions can be useful, for example, in the treatment of cancer.
1 - 22 . (canceled)
23 . A method for treating a brain tumor in a patient, the method comprising:
(a) targeting cancer stem cells in the brain tumor of a patient by administering to the patient a therapeutically effective amount of a CACNA1H antagonist, wherein the cancer stem cells exhibit expression activity in the Hs.459642 Unigene Cluster, wherein the CACNA1H antagonist is mibefradil or TTL-177; and
(b) administering an additional anti-cancer therapy to the patient, thereby treating the brain tumor.
24 . The method of claim 23 wherein the additional anti-cancer therapy is selected from the group consisting of surgery, radiation therapy, and administration of a chemotherapeutic agent.
25 . The method of claim 23 , wherein the patient is a human.
26 . The method of claim 23 , wherein the brain cancer is a glioblastoma.
27 . The method of claim 23 , wherein the antagonist is administered to the patient prior to the additional anti-cancer therapy.
28 . The method of claim 23 , wherein the antagonist and the additional anti-cancer therapy are administered to the patient simultaneously.
29 . The method of claim 23 , wherein the antagonist is mibefradil.
30 . The method of claim 23 , wherein the antagonist is TTL-177.
31 . The method of claim 23 , wherein the additional anti-cancer therapy is administration of a chemotherapeutic agent, and wherein the chemotherapeutic agent is temozolomide.
32 . The method of claim 23 , wherein the cancer stem cells are glioma stem cells.
33 . The method of claim 23 , wherein the cancer is a refractory or recurrent cancer.
