Blocking Fragment Of CDCP1
Utilizes CDCP1 as a novel therapeutic target for treating breast cancer as opposed to hormone receptorsMore effective at reducing tumor metastasis and preventing recurrence than generalized therapies (radiation, chemotherapy)
Treatment for triple-negative breast cancer and other breast cancers
Triple-negative breast cancer (TNBC) refers to any breast cancer that does not express the genes for estrogen receptor (ER), progesterone receptor (PR) or Her2/neu. There are currently no targeted therapies to treat TNBC and approximately 34% of TNBC patients experience recurrence or metastasis within five years of radiation and chemotherapy treatment. Researchers at UCI have identified a protein found on cell surfaces called CUB-domain containing protein 1 (CDCP1). CDCP1 controls fat metabolism by lowering fat levels inside cells, thus causing more fatty acid oxidation (FAO), which has been linked to metastasis of TNBC. As a method to target cancer cells that lack hormone receptors, blocking fragment that inhibit CDCP1 activity have been developed. Specifically, the fragment blocks CDCP1 dimerization, reducing FAO. Reduction of FAO is accompanied with inhibition of tumor growth and reduced metastasis.
