26802645 legumain might play an important role in cervical cancer cell migration and invasion.
26607955 Legumain appears to be involved in tumor development and deterioration.
26549211 AEP acts as a delta-secretase, cleaving APP at N373 and N585 residues, selectively influencing the amyloidogenic fragmentation of APP. AEP contributes to the age-dependent pathogenic mechanisms in Alzheimer disease.
26403494 Studies indicate that legumain, usually in lysosomes, is also found extracellularly and even translocates to the cytosol and the nucleus.
25605174 High legumain expression is associated with breast cancer.
25326800 AEP acts as a crucial mediator of tau-related clinical and neuropathological changes.
24742492 High legumain activity is associated with breast cancer.
24610907 Identified an alternative oncogenic pathway for TRAF6 that uses AEP as its substrate. AEP and TRAF6 protein levels may have prognostic implications in breast cancer patients. Thus, AEP may serve as a biomarker as well as new therapeutic target
24407422 This unique feature was confirmed by the crystal structure of AEPpH4.5 (AEP was matured at pH 4.5 and crystallized at pH 8.5), in which the broken peptide bonds were religated and the structure was transformed back to its proenzyme form.
24023813 the relationship among Legumain expression, clinicopathologic, biological variables and patient prognosis in gastric carcinoma
23942113 HCT116 cells were transfected with p53 siRNA and the effect of knockdown of p53 expression on legumain expression was examined. The results showed that expression levels of both legumain mRNA and protein were decreased in the siRNA-treated cells.
23776206 The multibranched and context-dependent activation process of legumain illustrates how proteases can act not only as signal transducers but as decision makers.
23640887 Involvement of brain acidosis in the etiopathogenesis of Alzheimer disease, and the asparaginyl endopeptidase-I2(PP2A)-protein phosphatase 2A-Tau hyperphosphorylation pathway.
23383108 A synthetic peptide corresponding to the immunosuppressive domain (amino acids 574-592) of HIV-1 gp41 downregulates the expression of legumain (LGMN) in peptide-treated PBMCs
23326369 In the HCT116 and SW620 cell lines nuclear Data indicate that legumain was found to make up approximately 13% and 17% of the total legumain, respectively.
23160071 glycosaminoglycans accelerated the autocatalytic activation of prolegumain
23124822 Prostate cancer with a vesicular staining pattern of legumain had the potential of being highly invasive and aggressive in patients treated with radical prostatectomy. This suggests that legumain might contribute to the invasiveness and aggressiveness.
22902879 Data show a regulatory role of cystatin E/M in controlling both intra- and extracellular legumain activity.
22718532 TDP-43 is cleaved by AEP in brain.
22441772 Increased legumain expression was validated by real-time PCR and Western blots, correlated positively with an increased malignancy of ovarian tumors.
22232165 Accepting asparagines and, to lesser extent, aspartic acid in P1, super-activated legumain exhibits a marked pH dependence that is governed by the P1 residue of its substrate and conformationally stabilizing factors such as temperature or ligands
20536387 The Lgmn can serve as novel target in diabetes mellitus genetic therapy.
20074384 the level of cystatin E/M regulates legumain activity and hence the invasive potential of human melanoma cells
19453521 GARP is a key receptor controlling FOXP3 in T(reg) cells following T-cell activation in a positive feedback loop assisted by LGALS3 and LGMN
18377911 Legumain is expressed in both murine and human atherosclerotic lesions, may play a functional role in atherogenesis
18374643 AEP may be a proteinases activated by acidosis triggering neuronal injury during neuroexcitotoxicity or ischemia.
15788679 Increased legumain expression is associated with primary colorectal cancer
15100291 Freshly isolated human B lymphocytes lack significant asparagine-specific endoprotease (AEP/legumain) activity; cleavage by AEP is dispensable for proteolytic processing of myelin basic protein in this type of cell.
12860980 human monocyte-derived dendritic cells harbor inactive proforms of AEP (legumain) that become activated upon maturation of dendritic cells with lipopolysaccharide
