Abstract (original English)
Breast cancer is one of the most common cancers in women and is closely associated with obesity. Gremlin-2 (GREM2), an antagonist for bone morphogenetic proteins (BMPs), has been considered an inhibitor of adipogenic differentiation in adipose-derived stromal/stem cells. However, the role of GREM2 in breast cancer cells remains largely unknown, and its signaling mechanism has yet to be clarified. Bioinformatics analysis was conducted using public databases. Breast cancer cells overexpressing mock or GREM2 were used for in vitro and in vivo studies. Cell viability, colony formation, migration, and animal studies were performed to investigate the role of GREM2 in breast cancer cells. Screening of target genes affected by GREM2 overexpression in breast cancer cells was performed through RNA sequencing (RNA-seq) analysis. The expression level of GREM2 mRNA was significantly reduced in both breast cancer tissues and cell lines. Kaplan-Meier analysis showed that low expression of GREM2 and high methylation of the GREM2 promoter were each associated with poor patient survival. The low mRNA expression of GREM2 in breast cancer cells was increased by the demethylating agent decitabine. Breast cancer cells overexpressing GREM2 decreased cell proliferation when compared to control cells, both in vitro and in vivo. Through comparison of RNA-seq analysis between cell lines and tissue sample
