Therefore, in the present study, we analyzed the ADIPOQ and ADIPOR1 protein levels in fresh breast tumour tissue and fresh breast adipose tissue adjacent to the tumour of postmenopausal women with normal BMI or with obesity, who had a histopathological diagnosis of early-stage operable invasive breast cancer and had a predominant luminal A subtype. Here, ADIPOR1 is linked to invasive breast carcinoma.
