Fig. 8: Proposed model demonstrating the epigenetic modification and functional significance of LINC00261 in the progression of pancreatic cancer.

The expression of LINC00261 is repressed by DNA methylation and EZH2-mediated H3K27 trimethylation. LINC00261 exerts its tumor suppressive function by regulating miR-222-3p/HIPK2/ERK axis and sequestering IGF2BP1.
