Several studies have sought to identify novel targeting molecules for use with cancer therapeutics; with successful examples including acids, peptides, polypeptides, or proteins based on molecules such as the FSH (Zhang et al., 2009, 2013; Fan et al., 2014; Hong et al., 2018), cyclic arginine-glycine-aspartic acid (cRGD) (Zhang Y. et al., 2020), folic acid (FA) (Abou-ElNaga et al., 2017), and hyaluronic acid (HA) (Zhao et al., 2019) that bind to known receptors more abundantly expressed on the surface of reproductive cancer cells. The gene discussed is BRD2; the disease is cancer.
