The up-regulation of CAP1 has been observed in several solid tumors, such as ovarian cancer, breast cancer (Xie et al., 2014; 2018; Hua et al., 2015; Hasan and Zhou, 2019), and rhabdomyosarcoma from which the TE671 cell line is derived (Rao et al., 2010). The gene discussed is CAP1; the disease is breast carcinoma.
