S100A13 and ovarian cancer: Additionally, high expression levels of S100A2, S100A4, S100A6, S100A7A, S100A10, S100A14, S100A16, S100B, and S100P have been associated with lower survival, whereas the upregulated expression of S100A1, S100A13, S100A5, S100A13, and S100G proteins have been associated with improved survival in patients with ovarian cancer [8].
