26856989 Results provided evidence for LRG1 function as a novel inducer of epithelial-mesenchymal transition and angiogenesis in colorectal cancer, which was at least partially through promotion of HIF-1alpha expression.
26517349 Data show that leucine-rich-alpha-2-glycoprotein 1 (LRG1) is markedly up-regulated and serves as an independent factor of poor outcomes in hepatocellular carcinoma (HCC).
26448929 Reanalysis of a total of 47 MDS patients revealed biomarker candidates, with alpha-2-HS-glycoprotein and leucine-rich alpha-2-glycoprotein as the most promising candidates.
26425690 Two of these proteins were verified in a separate patient cohort: values of CRP and LRG1 combined gave a highly significant indication of extended survival post one week of radiotherapy treatment.
26049667 Findings suggest that LRG1 promotes invasion and migration of glioma cells through TGF-beta signaling pathway.
25814288 LGR1 is involved in the inhibition of HCC metastasis.
25799488 Data found LRG1 as a promising candidate marker for detection of epithelial ovarian cancer (EOC) and the combination of LRG1 and CA125 showed improved performance to distinguish EOC including early stage EOC from non-cases compared to CA125.
25636050 Higher LRG1 is a significant predictor for arterial stiffness, endothelial function, and peripheral arterial disease.
25589464 silencing the expression of LRG1 suppresses the growth of glioblastoma U251 cells in vitro and in vivo, suggesting that LRG1 may play a critical role in glioblastoma development, and it may have potential clinical implications in glioblastoma therapy.
25277046 The blood proteins IGF1, IGF2, IBP2, IBP3 and A2GL have been proposed as indirect biomarkers for detection of GH administration and as putative biomarkers for breast cancer diagnosis.
25058884 Results suggest that serum LRG-1 is a promising biomarker for pancreatic cancer.
24760273 LRG1 potentially offered clinical value in directing personal treatment for endometrial carcinoma patients
24058569 Human LRG (hLRG) concentration in the cerebrospinal fluid (CSF) was measured and hLRG expression in post-mortem human cerebral cortex and mouse LRG (mLRG) in the brain were examined.
23284758 Overexpression of serum LRG1 is associated with non-small cell lung cancer.
22374925 High Serum leucine-rich alpha-2 glycoprotein is associated with ulcerative colitis.
22277732 Increased plasma levels of the APC-interacting protein MAPRE1, LRG1, and IGFBP2 precede a diagnosis of colorectal cancer in women
22116432 This study demonistrated that LRG expression in resident astrocytes increased with age.
21557262 Screened for NSCLC-related proteins in urinary exosomes by comparing urinary exosomes proteome of normal controls and NSCLC patients. The LRG1 was found to be expressed at higher levels in urinary exosomes and lung tissue of NSCLC patients.
21282491 LRG1 was identified as a serum biomarker that accurately identifies patients with heart failure.
20442399 autologous Cyt c is an endogeneous ligand for LRG and PLIbeta and these serum proteins neutralize the autologous Cyt c released from the dead cells
19851871 Serum LRG when bound to extracellular Cyt c that is released from apoptotic cells acts as a survival factor for lymphocytes and possibly other cells that are susceptible to the toxic effect of extracellular Cyt c.
19324010 These results strongly suggest that LRG was a secretory type 1 acute-phase protein whose expression was up-regulated by the mediator of acute-phase response.
17583700 Several indirect lines of evidence suggest a role for LRG in implantation/decidualization.
17194537 These results also indicate that the CSF level assay of TGF-beta1, TbetaR-II and LRG is useful for the diagnosis of patients with INPH, and TGF-beta1, TbetaR-II and LRG may be involved in the pathogenesis of the disease.
16699948 Mass spectrometry analysis identified the serum inhibitory factor as leucine-rich alpha-2-glycoprotein-1 in enzyme-linked immunosorbent assay .
12223515 cDNA clones for human leucine-rich alpha2-glycoprotein were isolated. LRG expression was up-regulated during neutrophil differentiation but down-regulated during monocytic differentiation. The hLRG gene was localized to chromosome 19p13.3.
