IGBP1 and small cell lung carcinoma: Sakashita et al. found its overexpression in small cell adenocarcinomas [58], and Li et al. found that in a lung adenocarcinoma cell line the interaction of IGBP1 and Lactoferrin could induce cell apoptosis [59], implying IGBP1 to be a candidate target for SCLC therapy.
