This invention relates to the field of biomedical technology, specifically to a micromolecule RNA-19b-3p and its application in the treatment of pancreatic ductal adenocarcinoma. The micromolecule RNA-19b-3p has the nucleotide sequence shown in SEQ ID NO:1. This invention discloses its use in the preparation of a medicament for treating pancreatic ductal adenocarcinoma, achieved by inhibiting the expression and / or activity of the micromolecule RNA-19b-3p. The medicament comprises a substance capable of reducing the expression or activity of the micromolecule RNA-19b-3p. This substance is its inhibitor, suppressor, antagonist, or antisense oligonucleotide. The medicament is used to inhibit the proliferation, migration, and / or invasion of pancreatic ductal adenocarcinoma cells. This invention provides a novel biomarker and therapeutic intervention target for pancreatic ductal adenocarcinoma, clarifies the feasibility of targeted therapy, and possesses clear translational potential.
