COL12A1 and familial pancreatic carcinoma: Based on the ceRNA hypothesis, a novel HCG11/NAMPTP1-miR-26b-5p-COL12A1 triple sub-network was constructed, which showed that overexpressed lncRNAs/pseudogenes mediate downregulation of hsa-miR-26b-5p leading to increased expression of COL12A1 in the progression of pancreatic cancer (Figure 11).
