    Breast cancer (BC) is a heterogeneous disease whose histopathological and molecular characteristics significantly affect the clinical outcome of patients


    Breast cancer (BC) is a heterogeneous disease whose histopathological and molecular characteristics significantly affect the clinical outcome of patients


    Bone is the most common metastasis site of BC, but there is no relevant biomarker for predicting bone metastasis of disease


    In this study, the researchers aimed to identify gene signatures associated with the onset of bone metastasis (BM) in circulating tumor cells (CTC) , which were isolated from 40 patients with metastatic BC through a DEPArray-based protocol, and based on the disease The metastasis sites are divided into groups, namely BM group (bone metastasis only), ES group (extra-bone metastasis) or BM+ES group (bone+extra-bone metastasis)

    The researchers further applied this set of data to the CTC group, especially the comparison between the BM group and the ES group


    The researchers identified 31 differentially expressed genes, including MAF, CAPG, GIPC1 and IL1B, which play a key prognostic role in BC




    Correlation between targeted RNAseq signature of breast cancer CTCs and onset of bone-only metastases.
