Abstract
The aim of this study is to determine whether there are differences in the expression of miR-155 and mRNA HIF1A in plasma ovarian cancer patients at the early stage compared with the advanced stage.
The samples using blood plasma from ovarian cancer patients RSUP Dr. Sardjito with 32 ovarian cancer patients early stages and 20 ovarian cancer patients advanced stages. Total RNA was isolated from blood plasma samples of ovarian cancer patients. cDNA synthesis from total RNA was performed to obtain cDNA. The expression of miR-155 and HIF1A were calculated using qPCR. qPCR results were analyzed using Biorad CFX Manager Software.
The analysis showed that the expression of miR-155 were 2,18 times lower (p-value = 0,018*) in the plasma of advanced stage ovarian cancer compared with early stage, the differences were statistically significant (p value≤ 0,05). Whereas the mRNA expression HIF1A were 2,46 times higher (p-value = 0,039*) in the plasma of advanced stage ovarian cancer compared with early stage, the differences were statistically significant (p value≤ 0,05).
This study has proved that miR-155 expression is downregulated and followed by upregulation of mRNA expression HIF1A at an advanced stage ovarian cancer compared with early stage.
