Alternative Title: Blocking the spread of breast cancer to bone
Current treatments are ineffective when breast tumours have spread to distant sites (metastasis). In particular, bone metastasis occurs in 70% of advanced breast cancer patients and causes severe morbidity. Cell surface receptors that promote cell attachment and movement are critical for the spread of tumours.
One such receptor, β3 integrin, is present on breast tumour, bone and blood cells and has been implicated in the spread of breast tumour cells but its role in bone metastasis is still unclear due to the lack of an appropriate model.
Miss Carter aimed to clarify the critical cell types expressing β3 integrin that are required for metastasis to bone and measure the therapeutic benefit of novel inhibitors targeting β3 integrin using a unique model of breast cancer metastasis to bone.
