To validate the role of KLF6 in the progression of PDAC, we collected 20 paired tumor tissues and non-tumor tissues from Ruijin Hospital to examine the expression of KLF6. RT-qPCR analysis revealed that the expression level of KLF6 was higher in tumor tissues and the IHC was further verified that KLF6 was infiltrated more in PDAC (Fig. 9A–C). Here, KLF6 is linked to neoplasm.
