Target Background

Major connective tissue mitoattractant secreted by vascular endothelial cells. Promotes proliferation and differentiation of chondrocytes. Mediates heparin- and divalent cation-dependent cell adhesion in many cell types including fibroblasts, myofibroblasts, endothelial and epithelial cells. Enhances fibroblast growth factor-induced DNA synthesis.
Gene References into Functions
  1. Findings suggested that hypoxia induced CTGF upregulation in hypoxic pulmonary hypertension (HPH) rat model. CTGF mediated hypoxia-induced regulation of miR-26b and SRF in proliferation of pulmonary arterial smooth muscle cells, which indicated that hypoxia-induced miR-26b inhibition contributed to the pathogenesis of HPH via CTGF. PMID: 28816418
  2. Ang II down-regulates KLF15 expression via the AT1 receptor, and KLF15 is likely to inhibit Ang II-induced CTGF expression by repressing the recruitment of the co-activator P/CAF to the CTGF promoter. PMID: 29179208
  3. our findings showed that miR-375 binds to 3'-UTR region of Ctgf mRNA, subsequently leading to the decreased expression of Ctgf in the I/R brain. Furthermore, we showed that miR-375/Ctgf-mediated protective effects are associated with p21/PI3K/Akt signaling pathways. PMID: 29187583
  4. The blocking of this pathway by its inhibitor LY294002 impaired the proliferative effect of CCN2 on chondrocytes. These results suggested a novel physiological role of CCN2 in the development of condylar cartilage. PMID: 29198711
