According to the research of Dong et al., up-regulation of the EMT-driving transcription factor Snail-1 in basal-like breast cancer cells leads to the formation of a Snail-G9a-Dnmt1 complex to silence the expression of fructose-1,6-bisphosphatase (FBP1), which is an important enzyme of gluconeogenesis (Dong C. et al., 2013). This evidence concerns the gene FBP1 and breast cancer.
