    2. HAI-1 is upregulated in pancreatic intraepithelial neoplasia and broadly expressed in pancreatic ductal adenocarcinoma (PDAC) cells. However, PDAC cases having areas of reduced HAI-1 immunoreactivity may show shorter disease-free survival. PMID: 29202869
    3. In this work, KLK14 binding to either hepatocyte growth factor activator inhibitor type-1 (HAI-1) or type-2 (HAI-2) was essayed using homology modeling, molecular dynamic simulations and free-energy calculations through MM/PBSA and MM/GBSA. KLK14 was successfully modeled. PMID: 28817220
    4. the cell surface expression of HAI-1 in all viable epidermal layers renders it an effective regulator for matriptase and prostasin PMID: 29438412
    5. Data suggest that HAI1, a protease on the surface of colon carcinoma cells, is an MMP7 substrate; proteolysis by MMP7 releases extracellular region as soluble HAI1 (sHAI1); sHAI1 induces cancer cell aggregation; cholesterol sulfate is required for MMP-7--catalyzed generation of sHAI1. (HAI1 = hepatocyte growth factor activator inhibitor type 1; MMP7 = matrix metalloproteinase-7) PMID: 29046355

    13. it was found that the recombinant fusion protein uPA17-34-KPI (kunitz-type protease inhibitor ) inhibited the invasion and metastasis of ovarian tumors PMID: 26166362
    14. HAI-1 may have a critical role in maintaining normal keratinocyte morphology through regulation of PAR-2-dependent p38 mitogen-activated protein kinase signaling. PMID: 25842366
    15. the anti-migratory effects seen via gamma-catenin were driven by the expression of hepatocyte growth factor activator inhibitor Type I (HAI-1 or SPINT-1), an upstream inhibitor of the c-MET signaling pathway. PMID: 25925948
    16. Data suggest HAI1 exhibits structural features consistent with classification in MANEC subclass of PAN/apple domain family with unifying features such as two additional disulfide bonds, two extended loop regions, and additional alpha-helical elements. PMID: 25510835
    17. Matriptase activity was suppressed by the expression of HAI-1. PMID: 24147538

    24. we showed for the first time that MT1-MMP activates matriptase through the cleavage of HAI-1 PMID: 22118498
    25. These data suggest that matriptase activity can be rapidly inhibited by HAI-1 and other HAI-1-like protease inhibitors and "locked" in an inactive autoactivation intermediate, all of which places matriptase under very tight control. PMID: 22031598
    26. HAI-1 and -2 are overexpressed in the liver in cholangiopathies with ductular reactions and are possibly involved in liver fibrosis and hepatic differentiation. PMID: 21898507

    28. Low HAI-1 is associated with endometrial cancer. PMID: 20715109
