The cell surface antigen mesothelin was found to be overexpressed in 67% of TNBC samples and is considered a potential target because of its involvement in the activation of intracellular pathways including MAPK, NFкB, and PI3K, resulting in tumor cell proliferation and resistance to apoptosis (Morello et al., 2016; Tchou et al., 2017). The gene discussed is MSLN; the disease is neoplasm.
