Cyclooxygenase-2 dependent expression of angiogenic
CXC chemokines ENA-78/CXC Ligand (CXCL) 5 and interleukin-8/CXCL8 in human non-small cell lung cancer ... To elucidate the
role of
COX-2 in the in vitro and in vivo expression of two known NSCLC angiogenic peptides,
CXC ligand ( CXCL ) 8 and CXCL5, we studied two COX-2 gene modified NSCLC cell lines, A549 and H157 ...
COX-2 overexpression
enhanced the in vitro expression of both
CXCL8 and CXCL5
Brant et al., Toxicological sciences : an official journal of the Society of Toxicology 2009
:
Consistent with our previous findings that Ni and MALP-2 stimulates the induction of CXCL8 via a COX-2 mediated pathway,
CXCL1 , CXCL5, and VEGF release were also
regulated by
COX-2
Katoh et al., Am J Pathol 2010
(Neoplasms...) :
Notably,
COX-2 inhibition
attenuated CXCL12/CXCR4 expression as well as expression of several other chemokines ... In addition, a
COX-2 inhibitor suppressed stromal formation and
reduced expression of
CXCL12/CXCR4 and a fibroblast marker ( S100A4 ) in a micropore chamber model

Nuclear factor-kappaB activation regulates
cyclooxygenase-2 induction in human astrocytes in
response to
CXCL12 : role in neuronal toxicity ...
CXCL12 induced
COX-2 and secretion of PGE ( 2 ) in a dose dependent manner in human astrocytes
Obermajer et al., Cancer Res 2011
(Ovarian Neoplasms) :
Similarly,
COX2 inhibition also
blocked CXCL12 production in the ovarian cancer environment and its ability to attract MDSCs. Together, our findings elucidate a central role for PGE ( 2 ) in MDSC accumulation triggered by the CXCL12-CXCR4 pathway, providing a powerful rationale to target PGE ( 2 ) signaling in ovarian cancer therapy
