25486458 There was a concomitant decrease in the phosphorylation of focal adhesion kinase and paxillin, indicating that DPP9 knockdown or enzyme inhibition suppressed the associated adhesion signaling pathway, causing impaired cell movement.
25464020 The DPP9 expressing cell model system is a very useful and promising system for investigating the selectivity and associated toxicity of DPP4 inhibitors on DPP9.
24562348 Whereas DPP9-short is present in the cytosol, DPP9-long localizes preferentially to the nucleus.
24072711 The SUMO1-E67 interacting loop peptide is an allosteric inhibitor of the dipeptidyl peptidases 8 and 9.

22736146 this study demonstrates for the first time that DP8 and DP9 are expressed in breast and ovarian carcinoma cell lines
22001206 residues important for dimer formation and enzymatic activity
21711053 Data identify modification points in the topology of a representative DPP8/9-inhibitor, capable of rendering selectivity for DPP8 over DPP9.
21622624 These findings suggest an important signaling role of DPP9 in the regulation of survival and proliferation pathways.
20534982 This is the first study to demonstrate the presence of DP9 in chronic lymphocytic leukemia.
20043068 DPP8 and DPP9 prevail over canonical DPP-IV/CD26 and FAPalpha in all examined meningioma patients
19667070 DPP9, a poorly characterized cytoplasmic prolyl-peptidase, is rate-limiting for destruction of proline-containing substrates both in cell extracts and in intact cells
19581630 DP8 and DP9 tissue and cellular expression
19268648 results indicate that the biochemical property of DPP9 is very similar to that of DPP8, its homologous protease. DPP9 and DPP8 are likely redundant proteins carrying out overlapping functions in vivo
18940951 The DPP9 gene is not associated with the occurrence or curve severity of AIS. It is neither a disease-predisposition nor a disease-modifying gene of AIS.
18940951 Observational study of gene-disease association. (HuGE Navigator)
16704418 Dipeptidyl peptidase 8 and dipeptidyl peptidase 9 influence cell-extracellular matrix interactions, and thus may regulate tissue remodeling.
16700509 cells overexpressing DP9 exhibit behavioral changesin the presence of ECM components; these effects were independent of enzyme activity
