Example sentences for: cxc
How can you use “cxc” in a sentence? Here are some example sentences to help you improve your vocabulary:
Sepsis is associated with a rapid release of CXC chemokines by alveolar macrophages, as well as up regulation of lung vascular intercellular adhesion molecule-1 (ICAM-1) expression [ 26 ] and these may contribute to the initial increase in adherent vascular neutrophils in the lung.
The genes for complement C3 and IP-10 (IFN-induced protein of 10 kDa), a non-ELR CXC chemokine, were among the genes upregulated by IL-4 in the monkey lung.
Interleukin-8 (IL-8) is a potent member of the supergene family of CXC chemokines with ELR motif (ELR+).
The CXC chemokines such as IL-8 were originally identified as potent activators and chemoattractants for neutrophils, whereas the CC chemokines such as MCP-1 and RANTES mostly attract monocytes and eosinophils respectively [ 10 ] . Chemokines are secreted in a stimulus-and cell type-specific manner [ 11 12 13 14 15 16 17 ] and are regulated primarily at the level of gene transcription [ 18 19 20 21 22 23 24 ] . The transcriptional promoters of IL-8, RANTES and MCP-1 contain binding sites for the redox-responsive transcription factor NF-κB, which has been shown to be important for their regulation by viral infections and cytokines [ 18 20 23 25 26 27 28 29 30 31 32 33 34 ] .
Several observations support the assertion that a complex interaction between IL-8 and several other growth factors, cytokines, or other proteins is responsible for these tumor-related events [ 5 9 10 11 12 13 ] . Growth regulated protein alpha (GRO-α), beta (GRO-β), and ENA-78 have been reported to be co-induced with IL-8 in A549 cells stimulated with two proinflammatory cytokines, IL-1β and TNF-α [ 14 ] . This result is consistent with the presence of nuclear factor kappa B (NF-κB) consensus binding sites in the promoter regions of all three genes [ 4 15 ] . In addition, GRO-α and -β are also members of the ELR +CXC cytokine family that are reported to be important mediators of tumorigenesis through their angiogenic properties [ 2 16 ] . They both share one of the IL-8 receptors, CXCR2, which has been postulated to regulate the ELR +CXC chemokine-mediated angiogenesis and resulting-tumorigenesis [ 1 ] . These observations suggest that GRO-α and -β may exhibit expression profiles similar to IL-8.
