HNF1A and familial pancreatic carcinoma: HNF1A and miR-504 expression changes were like those observed in vitro after LINC00673 knockdown or overexpression in tumors, as determined by qRT-PCR and shown in Fig. 7E. In addition, we found that LINC00673 may suppress pancreatic cancer deterioration by downregulating miR-504, which restrains HNF1A expression in vivo.
