MARCH8, an E3 ubiquitin ligase, plays a crucial role in regulating various cellular processes such as protein degradation and signaling pathways and is implicated in the development and spread of pancreatic cancer. Analysis of pancreatic cancer tissues compared to adjacent normal tissues showed a decrease in miRNA-30d-5p levels and an increase in OIP5-AS1 and MARCH8 levels, as confirmed by qRT-PCR and Western blot analysis. The dual-luciferase reporter assay demonstrated a binding relationship between OIP5-AS1 and miRNA-30d-5p, as well as between miRNA-30d-5p and MARCH8 in PACN-1 cells, derived from a human pancreatic carcinoma specimen. Further investigations utilizing various assays revealed that OIP5-AS1 inhibited apoptosis and promoted cell proliferation, invasion, and migration in PACN-1 cells via the miRNA-30d-5p/MARCH8 axis
