Figure Lengend Snippet: Prrx1b–Hgf signaling regulates pancreatic cancer cell invasion. ( A ) Prrx1a and Prrx1b target genes identified by ChIP-seq. Genes of enriched pathways (KEGG) are indicated. ( B ) Relative mHgf gene expression in control and Prrx1a-overexpressing and Prrx1b-overexpressing KP fl CY cells ( left ) and control and Prrx1a and Prrx1b knockdown KPC2 cells ( right ). (*) P < 0.05; mean ± standard deviation (SD). ( C ) Invasion assay in control and Prrx1a and Prrx1b knockdown cells using mrHGF. ( D ) Double IHC staining for PRRX1B (brown) and mHGF (blue) in KP fl CY pancreatic tumors (orthotopic transplantation model). Bars, 50 μm. ( E ) Quantification of secreted mHGF protein by ELISA. n = 3; mean ± SEM. ( F ) Secreted mHGF protein in the supernatant of control and Prrx1a/b knockdown KPC2 cells. n = 5; mean ± SEM.
Article Snippet: mHGF-secreted protein levels were measured in the supernatant of cultured cells as well as mouse serum using the mHGF DuoSet (R&D Systems, DY2207) according to the manufacturer's protocol.
