Abstract

Breast cancer is the most common cancer in women worldwide. miR-155 has been discovered to have an important role in the development of breast cancer. miR-155 targets many mRNAs of tumor suppressor genes, one of them is SOCS1. The discovery of miRNA in body fluids provides a novel alternative for the development of minimally invasive biomarker in cancer. However, limited study has been reported on the expression of miR-155 and SOCS1 mRNA in plasma breast cancer patients especially in Indonesian population.This study analyzed expressions of miR-155 and SOCS1 mRNA in plasma breast cancer patients This study was conducted using cross-sectional design, 32 plasma samples were collected from Dr.Sardjito Hospital. RNA was extracted from plasma and then cDNA was synthesized from RNA samples. Real-time qPCR was used to detect expression of miR-155 and mRNA SOCS1. Both expression was analyzed using Livak's method. The significance of the results were tested statistically using independence T-test. Expression of miR-155 at advanced stage was 2.43 higher than the early stages (p=0.047), while the mRNA expression of SOCS1 at advanced stage was 1.29 lower than early stage (p=0.170). Expression of miR-155 in ER, PR, & HER2 status revealed differences among subgroups, while the mRNA expression of SOCS1 was not significantly different. Other result showed that miR-155 expression was higher in triple negative tumor, while SOCS1 higher in luminal A tumor. Nevertheless, the difference was also not statistically significant (p value > 0,05). This study showed that expressions of miR-155 and SOCS1 mRNA was deregulated in breast cancer plasma and it believed to have an important role in breast cancer.
