Effect of Turkish propolis extracts on expression of voltage-gated sodium channel Nav 1.5 and 1.7 α-Isoforms in PC-3 human prostate cancer cells|
Uçar, Meltem; Değer, Orhan & Barlak, Yaşam
Purpose: To investigate the effect of dimethyl sulfoxide (DMSO) and water extracts of Turkish propolis
(WEP) on mRNA expression of Nav 1.5 and 1.7 α isoforms of Voltage-Gated Sodium Channel (VGSC)
proteins in PC-3 human prostate cancer cells.
Methods: DMSO and WEP (20 μg/mL each) were incubated for 24 h with PC-3 cells and total RNA was
extracted using a commercial kit. Real-time polymerase chain reaction (RTPCR) assay was used to
determine mRNA levels of the isoforms of VGSC. Expressions of VGSC were assumed to be 100 % in
PC-3 cells incubated without extract.
Results: Both extracts decreased the expression of VGSC isoforms to varying extents. Expressions of
Nav 1.5 and 1.7 was 61.43 ± 4.92 and 58.17 ± 2.88 %, respectively for DMSO; while for WEP, the
values were 83.54 ± 15.96 and 80.40 ± 13.87 20 μg/mL, respectively.
Conclusion: This results suggest that DMSO and water extracts of Turkish propolis may have antimetastatic
activity in PC-3 cells due to down-regulation of expressions mRNA of VGSC α-isoforms.
