Gelsolin expression was also determined in a panel of commercially-available colorectal tumor cell lines derived from primary tumors (HCT116, HT29, WiDr, RCM-1, RKO, Caco-2, SW837, SW480, SW403, DLD-1, LS513) as well as those obtained from metastatic lymph node (SW620) and ascites (COLO201 and COLO205). The gene discussed is GSN; the disease is colorectal neoplasm.
