Target Background

Function
(From Uniprot)
Appears to regulate cell growth through interactions with the extracellular matrix and cytokines. Binds calcium and copper, several types of collagen, albumin, thrombospondin, PDGF and cell membranes. There are two calcium binding sites; an acidic domain that binds 5 to 8 Ca(2+) with a low affinity and an EF-hand loop that binds a Ca(2+) ion with a high affinity.

  2. Plasma samples from lung cancer patients and healthy heavy-smokers controls were tested for levels of COL11A1 and COL10A1 (n = 57 each) and SPARC (n = 90 each). Higher plasma levels of COL10A1 were detected in patients (p PMID: 30227835
  3. The authors have confirmed the presence of SPARC expression in melanoma, Kaposi sarcomas (KS), leiomyosarcomas (LMS) and angiosarcomas (AS) and also detected it for the first time in atypical fibroxanthomas (AFX). PMID: 29660567
  4. Results revealed that hypermethylation of the SPARC promoter was the primary mechanism of SPARC downregulation in prostate cancer. SPARC expression was frequently lost during the promoter hypermethylation but could be restored by 5-Aza-Cdr. PMID: 29207175
  5. Stromal SPARC expression was a useful biomarker for predicting prognosis in patients with resected pancreatic ductal adenocarcinoma. PMID: 29295776
  6. SPARC is closely related to the development of breast cancer and can be used as a tumor marker for breast cancer recurrence. PMID: 29237913
  7. SPARC expression was inversely associated with the degree of malignancy and it had a negative correlation with VEGF-C and VEGF-D expression. Results suggest SPARC might function as a tumor suppressor inhibiting angiogenesis and lymphangiogenesis in ovarian cancer by reducing the expression of VEGF-C and VEGF-D. PMID: 29075785
  8. SPARC may be involved in gastric cancer metastasis by effecting on tumor microenvironment PMID: 29077165
  9. SPARC treatment enhances the epithelial mesenchymal transition signaling pathway via activation of AKT, and exogenous SPARC and tumor expressing SPARC might be associated with tumor progression in head and neck cancers. PMID: 28718842
  10. The epicardial adipose tissue expresses the mRNA of osteopontin, osteoprotegerin, and osteonectin genes that have been implicated in the calcification process; such expression is statistically associated with some components of HDL subclasses in coronary artery disease patients. PMID: 28821297

  15. The profiled circulating tumour cells also expressed elevated levels of stem cell markers, and the extracellular matrix protein, SPARC. The expression of SPARC might correspond to an epithelial-mesenchymal transition in pancreatic circulating tumour cells PMID: 28569190
  16. Data suggest that both osteonectin and FGF21 levels in serum are associated with early nephropathy in type 2 diabetes, albeit with different patterns; persistent hyperglycemia may inhibit bone formation leading to osteoporosis. (FGF21 = fibroblast growth factor 21) PMID: 27916484
  17. These results suggest that increased SPARC expression may be an indicator of greater aggressiveness, and may serve as a prognostic factor for triple-negative breast cancer. PMID: 27421134
  18. High expression of SPARC is related to worse prognosis in rectal cancer patients. PMID: 28009327
  19. Tumors with stroma-derived SPARC displayed suppressed growth, inhibited angiogenesis and increased lipid accumulation. Based on the described chaperone function of SPARC, authors hypothesized that SPARC binds albumin complexed with fatty acids and transports them to tumors. PMID: 27776337
  20. Weekly NAB-paclitaxel might be effective for heavily pretreated non-small-cell lung cancer patients. SPARC expression in tumor stroma cells might be a potential negative predictor of NAB-paclitaxel. PMID: 28304139
  21. SPARC-associated signaling pathways are associated with lymphangiogenesis and lymph node metastases of hypopharyngeal cancer. PMID: 29374693
  22. Stromal SPARC expression correlated with the prognosis of patients with resectable biliary carcinoma, and its significance was enhanced in patients treated with adjuvant gemcitabine-based chemotherapy. PMID: 28342122
  23. Studies revealed that SPARC plays a critical role in regulating bone remodeling and maintaining bone mass and quality. The mechanisms by which SPARC influences bone formation, maintenance, and repair might occur through multiple pathways that include the regulation of procollagen processing and assembly in the bone matrix, crosslinking, mineralization, and/or osteoblast/osteoclast differentiation and activity. [review] PMID: 26851678
  24. This study indicates that germline PTCH1 heterozygous mutations play a major role in bone metabolism in patients with NBCCS, in particular in those with PTCH1 protein truncation mutations. SPARC may represent an important downstream modulator of PTCH1 mediation of bone metabolism. PMID: 26890308
  25. The SPARC drives pathological responses in non-small cell lung cancer and idiopathic pulmonary fibrosis by promoting microvascular remodelling and excessive deposition of ECM proteins. PMID: 27759879
