Stanniocalcin-1 (STC1) is a secreted glycoprotein whose increasing expression is linked to poor prognosis, progression, and metastasis of a variety of tumors, such as breast cancer (Chang et al., 2015), ovarian cancer (Zhang C. et al., 2019), and colon cancer (Pena et al., 2013). Here, STC1 is linked to breast carcinoma.
