The aim of this study was to determine the comprehensive contribution of ANPEP polymorphisms to T2D risk and annotate the underlying mechanisms. A total of 3206 unrelated individuals including 1579 T2D patients and 1627 controls were recruited for the study. Twenty-three common functional single nucleotide polymorphisms (SNP) of ANPEP were genotyped by the MassArray-4 system. Six polymorphisms, rs11073891, rs12898828, rs12148357, rs9920421, rs7111, and rs25653, were found to be associated with type 2 diabetes (Pperm ≤ 0.05). Common haplotype rs9920421G-rs4932143G-rs7111T was strongly associated with increased risk of T2D (Pperm = 5.9 × 10–12), whereas two rare haplotypes such as rs9920421G-rs4932143C-rs7111T (Pperm = 6.5 × 10–40) and rs12442778A-rs12898828A-rs6496608T-rs11073891C (Pperm = 1.0 × 10–7) possessed strong protection against disease.

Integrative transcriptome analysis revealed close relation of CTSE to the extracellular matrix. scRNA-seq from TISCH2 demonstrated that CTSE is predominantly expressed in malignant LIHC cells. IHC confirmed higher CTSE expression in LIHC tissues compared to peritumoral tissues. Functional assays, such as qRT-PCR, Western blot, cell proliferation, and colony formation experiments, demonstrated that siRNA-mediated CTSE knockdown in HepG2 and Huh7 cell lines notably suppressed cell proliferation and altered the FAK/Paxillin/Akt signaling cascade.
