As oncogenic KRAS is known as a major event in the IPMN-PDAC sequence, we further evaluated Pten and Rnf43 depletion in the context of constitutively overexpressed KRASG12D (KC) (Figure 3(g)) using the above described lentiviral knockdown system on KC ductal organoids. The gene discussed is PTEN; the disease is pancreatic intraductal papillary-mucinous neoplasm.
