10. Our results showed 14% inferior plasma DPP-4 activity in adolescent idiopathic scoliosis (AIS) patients when compared to healthy controls . Similarly, osteoblasts derived from AIS subjects had lower DPP-4 gene and protein expression than controls by 90.5% and 57.1% respectively (P < 0.009). DPP-4 expression was regulated in a different manner in osteoblasts isolated from AIS participants compared to controls.

17. API was demonstrated to inhibit the migration/invasion of NSCLC cells harboring different EGFR statuses via suppressing the Snail/Slug-mediated EMT..CD26 may be a useful biomarker for predicting NSCLC progression. API effectively suppressed lung cancer progression by targeting the CD26-Akt-Snail/Slug signaling pathway

18. hepatocyte DPP4 promotes visceral adipose tissue inflammation and insulin resistance in obesity, and targeting this pathway may have metabolic benefits that are distinct from those observed with oral DPP4 inhibitors

19. this study shows that CD26 expression is down-regulated on CD8(+) T cells in patients with Hashimoto's thyroiditis

20. Several isoforms of DPP-IV and FAP are present in glioblastoma tissue. The absence of alkaline isoforms of both enzymes in glioma cell lines however suggests that isoforms from other, most likely stromal, cell types contribute to the overall pattern seen in glioblastoma tissues.

Cow (Bovine) Dipeptidyl-Peptidase 4 (DPP4) Interaktionspartner

1. Results describe a proline-rich cytokine from neurosecretory granules that represents a new natural substrate for Dipeptidyl Peptidase IV (DPPIV).

2. This and other dipeptidyl peptidases can be isolated from bovine testes.

3. Data demonstrate that dipeptidyl peptidase II can form a complex with adenosine deaminase, but with one order of magnitude higher dissociation constant than that of DPPIV.

Pig (Porcine) Dipeptidyl-Peptidase 4 (DPP4) Interaktionspartner

1. This study shows that porcine DPP-IV is generally inhibited with greater potency by protein-derived peptides than is the human enzyme

2. DPP-IV from porcine kidney cortex was characterized.

3. Neutral endopeptidase 24.11 and DPP-IV is superior to DPP-IV inhibition alone in preserving intact GLP-1, which implies possibility that the combination has therapeutic potential.

4. Results describe the distribution of dipeptidyl peptidase IV-like activity enzymes in porcine tissue sections by RT-PCR.

Xenopus laevis Dipeptidyl-Peptidase 4 (DPP4) Interaktionspartner

1. Dpp4 and Xnr1 showed synergistic effect on induction of ectopic dorsal body axis, when co-injected at suboptimal doses in early embryos. Overexpression of Dpp4 disrupted specification of dorsal body axis of embryo, leading to malformed phenotypes such as spina bifida and a shortened and dorsally bent axis.

Mouse (Murine) Dipeptidyl-Peptidase 4 (DPP4) Interaktionspartner

1. Of the six biomarkers, only COMP and DPP4 showed high and SPP1 moderate correlation with the spinal muscular atrophy phenotype. PLS3 overexpression neither influenced the SMN level nor the six biomarkers, supporting the hypothesis that PLS3 acts as an independent protective modifier.
