OBJECTIVE: To verify the effect and mechanism of emodin combined with apatinib mesylate in inhibiting the proliferation of pancreatic cancer cells by up-regulating the angiotensin converting enzyme 2( ACE2)-Angiotensin( 1-7) [Ang( 1-7) ]-Mas receptor.METHODS: Methyl Thiazolyl Tetrazolium( MTT) was used to detect the effects of emodin
apatinib mesylate and drug combination( emodin + apatinib mesylate) on the proliferation of PANC-1 cells.Without medicine were took as the control.Enzyme-linked immunosorbent assay was used to determine the levels of interleukin 6( IL-6) and Ang( 1-7) in the cell supernatant.Western blot method and immunofluorescence method were used to detect the expression of ACE2 and Mas receptor protein in each experimental group.RESULTS:After intervention
the cell inhibition rate of the emodin group
apatinib mesylate group and drug combination group was respectively 11.72%
15.94% and 28.84%
the drug combination group was significantly higher than the single drug group
the differences were statistically significant( P <0.05).The level of IL-6 in the apatinib mesylate group was significantly lower than that in the emodin group
and that in the drug combination group was significantly lower than that in the emodin group and the apatinib mesylate group.In contrast to the level of IL-6
Ang( 1-7) in the emodin group
apatinib mesylate group and combination group was significantly higher than that in the control group
and the drug combination group had the highest Ang( 1-7)
with statistically significant difference( P < 0.01).The results of Western blot and immunofluorescence showed that the expression levels of ACE2 and Mas receptor protein in the emodin group and apatinib mesylate group were higher than those in the control group
and the expression levels of ACE2 and Mas receptor protein in the drug combination group were the highest.CONCLUSIONS: The monotherapy of emodin and apatinib mesylate inhibits the proliferation of pancreatic cancer cells by up-regulating the ACE2-Ang( 1-7)-Mas receptor axis
and the combination of two drugs has a synergistic effect.
