CREB1 promotes cholangiocarcinoma metastasis through transcriptional regulation of the LAYN-mediated TLN1/β1 integrin axis: CREB1 promotes cholangiocarcinoma metastasis through regulating LAYN/TLN1/β1 integrin axis.

Background: Layilin (LAYN) plays an important role in tumor progression, invasion, and metastasis; however, its role in cholangiocarcinoma (CHOL) has not been elucidated.

Methods: We utilized the GEPIA, STRING, and hTFtarget databases for bioinformatics analysis. Overexpression or knockdown cell lines were constructed by transfecting the cells with different plasmids.
