    STC2 is a glycoprotein widely expressed in various tumor cells and tumor tissues such as breast, colorectum, stomach, esophagus, prostate, kidney, liver, bone, ovary, and lu.


    Importantly, STC2 also promotes the development of acquired resistance to chemotherapy and radiation thera.

    Recently, researchers from Tianjin Medical University Cancer Institute and Hospital published an article entitled "Stanniocalcin 2 (STC2): a universal tumor biomarker and a potential therapeutical target" in the journal J Exp Clin Cancer R.


    Human STC2 is a protein composed of 302 amino acids, and Aa1-24 is the signal peptide for endoplasmic reticulum transpo.

    ATF4 plays a key role in mediating the integrated stress response (IRS), and ATF4 is closely related to the expression of STC The tumor microenvironment is characterized by imbalanced oxygen levels, inadequate nutrient supply, and low pH; these stressful conditions lead to endoplasmic reticulum stress, disrupt protein maturation, accumulate unfolded or misfolded proteins, and ultimately activate evolutionarily conserved responses , Unfolding Protein Response (UP.
