Immunostaining results also showed scattered cells expressing the ATM target phospho-Kap16, 7 in both the KC and KCATMΔ+ pancreatic tumor epithelium (Fig. 1E), and absence of this protein in KCATMΔΔ pancreatic tumor epithelial cells (Fig. 1E). The gene discussed is CALCA; the disease is pancreatic neoplasm.
