Target Background

Gene References into Functions
  1. LRG-1 was highly expressed in human retinoblastoma sections, thus providing new insights into the molecular mechanism of retinoblastoma pathogenesis, and suggests a possible new therapeutic target. PMID: 29392314
  2. The detection of LRG1 in accordance with the DeltaRct value (electron-transfer resistance at the electrode surface) of the sensor layer incorporating LRG1 BP3 peptides showed a statistically significant difference (p < 0.001) between adenomas and carcinomas, indicating that the potential use of this biosensing platform for detecting the CRC biomarker, as well as for monitoring the colorectal adenoma-to-carcinoma tra... PMID: 28697446
  3. This study shows that TNF-alpha is the predominant proinflammatory cytokine that induces the secretion of LRG1. LRG1 contributes to angiogenesis-coupled de novo bone formation by increasing angiogenesis and recruiting MSCs in the subchondral bone of osteoarthritis joints. PMID: 28358372
  4. the expression of 3 miRs and 9 mRNAs associate with the PIK3CA status. Expression of LRG1 is independent of luminal (A or B) subtype, decreased after neo-adjuvant aromatase inhibitor treatment. PMID: 27491861
  5. Plasma LRG1 predicts both albuminuria and Chronic kidney disease progression beyond traditional risk factors. It may play a role in the pathologic pathway leading to progression of diabetic kidney disease in T2 Diabetes mellitus. PMID: 28973352
  6. LRG1 may be a key regulatory factor of allergic responses. PMID: 27378305
  7. Results find serum LRG1 levels are significantly associated with LRG1 expression in gastric tumors. Its inhibition suppresses gastric cancer cell growth and invasion suggesting that LRG1 is implicating in gastric tumorigenesis. PMID: 28746773
  8. LRG1 plays a crucial role in the proliferation and apoptosis of colorectal cancer (CRC) by regulating RUNX1 expression. LRG1 may be a potential detection biomarker as well as a marker for monitoring recurrence and therapeutic target for CRC. PMID: 28376129
  9. These findings suggest that sputum LRG is a promising biomarker of local inflammation in asthma. PMID: 27611322
  10. combination of modified whole blood LRG1 mRNA levels, plasma LRG1 protein and Alvarado score at the ED may be useful to diagnose simple and complicated acute appendicitis from other causes of abdominal pain PMID: 28202345
  11. Downregulation of LRG1 is associated with head and neck squamous cell carcinoma. PMID: 28098902
  12. Results suggest that serum LRG-1 is a promising biomarker for pancreatic cancer. PMID: 25058884
  13. 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. PMID: 26856989
  14. 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). PMID: 26517349
  15. 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. PMID: 26448929
  16. 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. PMID: 26425690
