Objective: To explore the mechanism of zedoary turmeric oil on tumor angiogenesis through the research of zedoary turmeric oil effect on vascular endothelial growth factor (VEGF) and chemokine(CXC) protein expression levels in rectal cancer SW1463 cells. Method: Steam distillation was used to extract volatile oil from Rhizoma curcuma
and prepared into different concentrations 80
120
160 and 200 mg·L-1. After 24 h treatment on rectal cancer SW1463 cells
their effects on morphology of rectal cancer SW1463 cells were observed by inverted microscope. The protein expression levels of VEGF
CXC
interleukin(IL)-8 and its receptors CXCR2
CXCR3 in rectal cancer SW1463 cells were detected by immunocytochemistry and Western blot. Result: After treatment on rectal cancer SW1463 cells for 24 h by zedoary turmeric oil
the protein expression levels of VEGF
IL-8 and CXCR2 in cells were significantly down-regulated as compared with the normal blank group (P<0.05
P<0.01). The protein expression levels of VEGF
IL-8
CXCR2 could be inhibited in tumor cells by zedoary turmeric oil. However
the protein expression level of CXCR3 in cells was significantly up-regulated as compared with the normal blank group (P<0.05
P<0.01). The protein expression level of CXCR3 can be promoted in tumor cells by zedoary turmeric oil. Conclusion: Different concentrations of zedoary turmeric oil from Guizhou can inhibit rectal cancer SW1463 cells proliferation and alter cellular morphology. Zedoary turmeric oil from Guizhou can inhibit tumor angiogenesis through down-regulation of pro-angiogenesis-associated factors VEGF
IL-8
CXCR2 and up-regulation of angiogenesis-related chemokines CXCR3.
