1 .- 139 . (canceled)
140 . A method of diminishing the levels of osteolysis in a subject having a cancer comprising: reducing the activity of Hedgehog (Hh) in a cancer cell of the subject.
141 . The method of claim 140 , wherein reducing the activity of Hedgehog (Hh) comprises reducing the level of a nucleic acid encoding OPN or the level of OPN protein in the cancer cell.
142 . The method of claim 141 , wherein reducing the level of a nucleic acid encoding OPN or the level of OPN protein comprises administering to the subject an isolated nucleic acid selected from the group consisting of a small hairpin RNA (shRNA), a small interfering RNA (siRNA), an artificial micro RNA (miRNA), an antisense polynucleotide, and a ribozyme.
143 . The method of claim 140 , wherein reducing the activity of Hedgehog (Hh) comprises reducing the level of a nucleic acid encoding GLI1 or the level of GLI1 protein in a cancer cell of the subject.
144 . The method of claim 143 , wherein reducing the level of a nucleic acid encoding GLI1 or the level of GLI1 protein comprises administering to the subject an isolated nucleic acid selected from the group consisting of a small hairpin RNA (shRNA), a small interfering RNA (siRNA), an artificial micro RNA (miRNA), an antisense polynucleotide, and a ribozyme.
145 . The method of claim 144 , wherein the isolated nucleic acid comprises a sequence encoding GLI1 or a fragment thereof, a sequence encoding antisense GLI1 or a fragment thereof, or an antisense nucleic acid complementary to a sequence encoding GLI1 or a fragment thereof.
146 . The method of claim 145 , wherein the isolated nucleic acid comprises a sequence selected from SEQ ID NO.s:1-10.
147 . The method of claim 140 , wherein the Hedgehog (Hh) comprises Sonic Hedgehog (SHh).
148 . The method of claim 140 , wherein the cancer is breast cancer.
149 . The method of claim 148 , wherein the breast cancer is an infiltrating ductal carcinoma or a metaplastic carcinoma.
150 . A method of regulating osteoclast differentiation in a subject, comprising reducing the activity of Hedgehog (Hh) in a cancer cell of the subject.
151 . The method of claim 150 , wherein reducing the activity of Hedgehog (Hh) comprises reducing the level of a nucleic acid encoding OPN or the level of OPN protein in the cancer cell.
152 . The method of claim 151 , wherein reducing the level of a nucleic acid encoding OPN or the level of OPN protein comprises administering to the subject an isolated nucleic acid selected from the group consisting of a small hairpin RNA (shRNA), a small interfering RNA (siRNA), an artificial micro RNA (miRNA), an antisense polynucleotide, and a ribozyme.
153 . The method of claim 152 , wherein reducing the activity of Hedgehog (Hh) comprises the level of a nucleic acid encoding GLI1 or the level of GLI1 protein in the cancer cell of the subject.
154 . The method of claim 153 , wherein reducing the level of a nucleic acid encoding GLI1 or the level of GLI1 protein comprises administering to the subject an isolated nucleic acid selected from the group consisting of a small hairpin RNA (shRNA), a small interfering RNA (siRNA), an artificial micro RNA (miRNA), an antisense polynucleotide, and a ribozyme.
155 . The method of claim 154 , wherein the isolated nucleic acid comprises a sequence encoding GLI1 or a fragment thereof, a sequence encoding antisense GLI1 or a fragment thereof, or an antisense nucleic acid complementary to a sequence encoding GLI1 or a fragment thereof.
156 . The method of claim 155 , wherein the isolated nucleic acid comprises a sequence selected from SEQ ID NO.s:1-10.
157 . The method of claim 150 , wherein the Hedgehog (Hh) comprises Sonic Hedgehog (SHh).
158 . The method of claim 150 , wherein the cancer is breast cancer.
159 . The method of claim 158 , wherein the breast cancer is an infiltrating ductal carcinoma or a metaplastic carcinoma.
