Several diseases have been linked to the dysfunction of anoctamins. Anoctamins play a wide range of physiological roles, including cell proliferation, migration, epithelial secretion, and calcium-activated chloride channel activity. However, the function of anoctamin 10 (ANO10) in breast cancer is still unclear. ANO10 was highly expressed in bone marrow, blood, skin, adipose tissue, thyroid gland and salivary gland, while ANO10 was expressed at low levels in liver and skeletal muscle. Compared to benign breast lesions, the protein level of ANO10 was lower in malignant breast tumors. However, breast cancer patients with low ANO10 expression have favorable survival outcomes. ANO10 was negatively correlated with the infiltration of memory CD4 T cells, naïve B cells, CD8 T cells, chemokines and chemokine receptors. Furthermore, the ANO10 low expression group was more sensitive to certain chemotherapy drugs, including bleomycin, doxorubicin, gemcitabine, mitomycin and etoposide. Altogether, ANO10 is a potential biomarker that can effectively predict the prognosis of breast cancer. Our findings highlight the promising prognostic value and therapeutic target of ANO10 in breast cancer.
